Waves traveling across the surface of the sea tend to move relatively slowly. Likewise, their oscillations tend to have relatively long periods, e.g., on the order of eight to twenty seconds. However, despite their relatively slow movement, waves tend to possess and/or manifest substantial amounts of energy. For these reasons, it is both desirable and difficult to extract energy from ocean waves. The device of the current invention efficiently extracts energy from ocean waves with a robust and relatively inexpensive design having few or no moving parts.
A variety of embodiments of the current invention contribute to solving at least two significant limitations and/or drawbacks of large-scale computing.
A variety of embodiments of the current invention also solve at least two significant limitations and/or drawbacks of aquaculture.
Disclosed are a novel type of buoyant hydrodynamic pump and a novel type of wave engine configured to float adjacent to an upper surface of a body of water over which waves tend to pass. Embodiments incorporate at least one tube (also referred to herein as a liquid pressurizing columnar conduit, water tube, tapered tube, constricted tube, or inertial water tube, inter alia) with an opening, or mouth, at a lower portion and a constriction or narrowing at or near an upper mouth. The tube partially encloses a substantial volume of water that tends to be excited and oscillate within the tube in response to wave action at the device, in particular because of interactions between that water and the tube's constriction, taper, or reduction in cross-sectional area. Embodiments incorporate a buoy (also referred to herein as a flotation module, hollow chamber, buoyant enclosure, buoyant body, flotation capsule, hollow flotation module, or upper hull enclosure, inter alia) to which an upper part of the tube is connected. Wave-driven oscillations of the device, and its attached tapered or constricted tube, result in the periodic ejections of portions of the water inside the tube, at the top and/or from an upper mouth of the tube (referred to as an injection orifice, water discharge mouth, or water discharge spout, inter alia). In some embodiments, portions of said ejected water may be collected in a reservoir (also referred to herein as a liquid collecting chamber, water tank, interior enclosure, or water collection basin, inter alia) that is positioned and configured so that: (1) a surface of water within the reservoir can be maintained at a position above the mean water level of the body of water on which the device floats, i.e., the resting external water surface; and/or (2) the water within the reservoir can be held in state of elevated pressure by compressed air or gas contained in the same enclosure and/or a fluidly communicating enclosure. Water within such an elevated or pressurized reservoir may return to the body of water on which the device floats via an effluent conduit (also referred to herein as an effluent pipe, inter alia) within which is situated a turbine or another power-capture mechanism such as a magnetohydrodynamic generator, thereby permitting the generation of electrical power; or through another type of flow governor, such as an adsorbent filter, configured to regulate and/or govern the flow of water out of the reservoir. In some cases, the flow governor can produce useful work and/or a useful product as a consequence of water flow, such as the capture of dissolved substances in seawater. In other cases the utility of the flow governor is primarily the maintenance of an approximately constant pressurization of the device's reservoir and/or an approximately constant, or controllable, flow of water through the hydrodynamic pump.
A preferred embodiment is characterized by a waterplane area that is at least five times greater than the average horizontal cross-sectional area of the upper surface of the resting water partially enclosed within the tube. A preferred embodiment is characterized by a buoy that is quasi-spherical especially in the region of a resting waterline. A preferred embodiment is free-floating, unmoored, self-propelled, and possessing computing devices that are used to process computational tasks transmitted to it by a satellite, or by other electromagnetically- or optically-encoded signals, so that it can perform computational tasks on demand and/or autonomously, far from any shore and/or in the midst of waves that tend to be more energetic than those found near shore. Another preferred embodiment promotes the growth of fish, macroalgae, microalgae, bivalves, and/or other organisms, within the reservoir of the device, sometimes by using a portion of the energy that it generates to generate light to support their growth and/or to propel the device to locations offering favorable environmental resources. Another preferred embodiment captures minerals dissolved in seawater by using the pumping action of the embodiment to drive water at elevated pressure through or adjacent to an adsorbent or absorbent capture medium. Another preferred embodiment uses the water-pumping action of the embodiment to circulate water to create a hospitable and waste-free environment for fish captive within a reservoir of the embodiment. Finally, another preferred embodiment uses its water-pumping action to propel seawater skywardly to increase the number of cloud nucleation sites in the air above the embodiment.
A downward movement of the tapered tube, relative to the position and/or movement of the water partially enclosed within the tube, such as might occur as the device falls from the crest of a wave toward an approaching trough, tends to cause the tapered walls of the tapered tube to impart an increased pressure to the water inside the tube, particularly at an upper region of that water column. When such a downward movement of the tube is followed by an upward movement of the tube, such as might occur as the device rises from the trough of a wave toward an approaching crest, the water inside the tapered tube tends to continue moving downward for a period of time due to its substantial inertia and downward momentum, even as the tapered tube moves upward and away from that water. The resulting disparity in the movements of the tapered tube and the water therein tends to cause a reduction in the pressure inside an uppermost portion of the tapered tube, and, in some embodiments, causes air to be drawn into the tube from above.
When the volume of water within the tapered tube has been reduced (e.g., when a transient air pocket has developed at the top of the tube), then the inward and/or upward pressure exerted by the water outside and/or adjacent to the lower mouth of the tapered tube that would tend to push water back into the tube, and restore the tube's nominal volume of water, will tend to exceed the outward and/or downward pressure exerted by the reduced volume of water within the tapered tube at the lower mouth. The resulting net inward and/or upward pressure at the tapered tube's lower mouth will tend to impel water back into the tapered tube from below. And, as the water within the tapered tube moves up the tube, toward the tapered tube's upper mouth, that water tends to accelerate and gain upward momentum.
As the rise of the device and the device's tapered tube slows, and/or the device returns to a downward trajectory, the vertically stalled, and/or now descending, tapered tube will tend to encounter an upward-moving slug of water partially enclosed within the tapered tube that is still moving upward and/or still gaining upward momentum. As the transient air pocket at the top of the tube is reduced, and the upwelling water within the tapered tube again reaches its nominal height within the tapered tube, the narrowing cross-sectional area of the tapered tube, and/or the tube's constricted upper end, tends to cause a portion of the water moving up through the tapered tube to gain additional upward speed (relative to the tube) and to subsequently travel beyond the upper mouth of the tapered tube and to effectively be ejected therefrom. In embodiments having a reservoir (liquid collecting chamber), especially one pressurized by gas, this ejection of water from the tube corresponds to an injection of water into the liquid collecting chamber; the pressure and/or force required to perform this injection is supplied by the sizable momentum and/or inertia of the water moving upwardly (relative to the tube) in the relatively long tube.
An embodiment of the current disclosure traps a portion of the water discharged from the upper mouth of its tapered tube within a raised or elevated water reservoir, i.e., within a reservoir, container, chamber, pool, tank, bath, vat, and/or other full or partial enclosure configured so that in normal operation the reservoir holds a substantial portion of the water therein, and/or a surface of the water therein, at a distance above the mean external water level of the body of water on which the device floats, thereby capturing, preserving, buffering, storing, and/or caching, as gravitational potential energy some of the energy of water ejected from the upper mouth of the device's tapered tube. In embodiments having this kind of elevated or raised reservoir, the embodiment is typically configured to have at least some permanent buoyancy, i.e. structures having a lower density than water positioned so as to reside below a mean waterline of the embodiment during normal operation. An embodiment allows a portion of the water trapped within its raised reservoir to flow back into the body of water on which the device floats through at least one water turbine that is operatively connected to at least one electrical generator, such that water flowing through said turbine, under the influence of the head pressure possessed by the water within the raised reservoir, results in the production of electrical energy. Embodiments of the current disclosure may utilize any type of hydrokinetic, impulse, or reaction turbine, including, but not limited to, those that might be characterized as: Kaplan turbines, Francis turbines, and crossflow turbines.
An embodiment of the current disclosure utilizes and/or incorporates a pressurized accumulator, reservoir, chamber, vessel, container, capsule, tank, and/or other enclosure, containing both air and seawater, into which seawater is injected from the tapered tube. The pressurized reservoir traps a portion of the water discharged from an upper mouth of its tapered tube within a pressurized water reservoir, i.e., within a reservoir, container, chamber, pool, tank, capsule, and/or other enclosure, thereby holding the water alongside a pocket of compressed air, thereby capturing, preserving, buffering, storing, and/or caching, potential energy as an increased gas pressure. The pressurized reservoir stores potential energy in the compressed air inside the accumulator, much like a hydraulic accumulator. An embodiment allows a portion of the water trapped within its pressurized reservoir to flow back into the body of water on which the device floats through at least one water turbine that is operatively connected to at least one electrical generator such that water flowing through said turbine, under the influence of the elevated pressure possessed by the water within the pressurized reservoir, results in the production of electrical energy. Embodiments of the current disclosure may utilize any type of hydrokinetic, impulse, or reaction turbine, including, but not limited to, those that might be characterized as: Kaplan turbines, Francis turbines, and crossflow turbines.
An embodiment of the current disclosure utilizes and/or incorporates at least one water reservoir possessing at least one approximately elliptical or circular (nominally horizontal) cross-section, e.g., within a plane normal to a (nominally vertical) longitudinal axis of the device and/or its tapered tube. And the embodiment introduces a portion of the water discharged from the upper mouth of the tapered tube into the circular water reservoir at a position, and in a direction, that has a component tangential to the periphery of the elliptical or circular cross-section of the reservoir such that a swirling motion tends to be imparted to a portion of the water within the reservoir. One such embodiment utilizes a hydrokinetic turbine that extracts energy from both the gravitational potential energy (e.g., head pressure potential energy) and the (rotational and/or angular) kinetic energy of the water in the reservoir.
An embodiment of the current disclosure incorporates, includes, and/or utilizes a tapered and/or constricted tube, cylinder, channel, conduit, container, canister, object, and/or structure, an upper end of which is nominally positioned adjacent to, or above, a mean exterior waterline of the device, and a lower end of which is nominally positioned at a depth near, adjacent to, and/or below, a wave base of the body of water on which the embodiment floats, e.g. (depending on the scale of the embodiment) 20, 50, 100 meters, 150 meters, or 175 meters below the mean free surface, or in any event, at a depth substantially below the free surface of the body of water. Cross-sectional areas of the tapered tube relative to sectional planes normal to a nominally vertical, longitudinal axis of the embodiment and/or the tube (and hence parallel to a resting and/or average free surface of the body of water), are typically inconstant and preferably greater near a lower extent or portion of the tube, and lesser near an upper extent or portion of the tube, i.e., the tube (liquid pressurizing columnar conduit) narrows and/or contains a constriction or constricting feature near its upper end.
The constricted or tapered tube of a preferred embodiment has a lower portion, e.g., adjacent to a lower mouth of the tube, that is of relatively constant cross-sectional area and an upper portion, e.g., approaching an upper mouth of the tube, that is of a lesser, decreasing, and/or constricted cross-sectional area. An upper portion of the tapered tube of one such preferred embodiment is comprised of a frustoconical segment wherein the upper mouth is defined by the smallest-diameter edge of that frustoconical segment. An upper portion of the tapered tube of a different preferred embodiment has a region of approximately constant (transverse) cross-sectional area above the constricting section, such that an uppermost portion of the tube can be approximately cylindrical and/or prismatic. An upper portion of the tapered tube of another such preferred embodiment is comprised of a conical segment with walls that are curved with respect to cross-sectional planes passing through, and/or including, the longitudinal axis of the lower tube portion, e.g. to cause the constricting part of the tube to have walls completely tangential to the walls of any cylindrical or prismatic regions above or below. A (non-preferred) embodiment has a tapered tube of relatively constant cross-sectional area and an orifice plate near its top, the orifice of which comprises the upper tube mouth.
The tapered tube of another embodiment is smoothly tapered from a bottom of relatively great cross-sectional area to a top of relatively small cross-sectional area. The tapered tube of another embodiment has cross-sectional areas that increase with greater depth within a first depth range and are approximately constant within a second depth range, the second depth range being deeper in the body of water on which the embodiment floats than the first depth range. The tapered tube of another embodiment has cross-sectional areas that are constant with greater depth within a first depth range, are increasing with depth within a second depth range, and are approximately constant with depth in a third depth range, the second depth range being deeper in the body of water than the first depth range and the third depth range being deeper in the body of water than the second depth range.
Tapered tubes of the current disclosure include, but are not limited to, those which have a horizontal cross-section, i.e., a cross-section through a plane normal to a (nominally vertical) longitudinal axis of the tube, that is approximately circular, elliptical, rectangular, hexagonal, and/or octagonal, as well as those which have a horizontal cross-section that is irregular or of some or any other shape.
Tapered tubes of the current disclosure include, but are not limited to, those which have an internal channel, e.g., through which water and/or air may flow, which have horizontal cross-sections, i.e., a cross-sections through a plane normal to a (nominally vertical) longitudinal axis of the tube, that is approximately circular, elliptical, rectangular, hexagonal, and/or octagonal, as well as those which have a horizontal cross-section that is irregular or of some or any other shape.
Tapered tubes of the current disclosure include, but are not limited to, those that are relatively straight, e.g., vertical, and have a straight longitudinal and/or central axis, e.g., parallel to the axis of fluid flow through the tube. Water tubes of the current disclosure also include, but are not limited to, those that are curved and have a non-linear and/or curved longitudinal and/or central axis or centerline, e.g., parallel to the axis of fluid flow through the tube.
Tapered tubes of the current disclosure include, but are not limited to, those which have an internal channel, e.g., through which water may flow, with variable, inconsistent, and/or changing, cross-sectional areas, i.e., a variable, inconsistent, and/or unequal, area with respect to at least two cross-sections through a plane normal to a longitudinal axis or centerline of the tube.
Tapered tubes of the current disclosure include, but are not limited to, those which have a divided, partitioned, and/or separated internal channel, e.g., through which water may flow, through two or more separated channels within a single tube. For example, an embodiment may incorporate and/or utilize a single tube that, by means of one or more substantially vertical partitions that are approximately parallel to the vertical longitudinal axis of the tube, incorporates two or more separated channels through which water may flow. Such a divided and/or partitioned tube permits the possibility and/or the opportunity to incorporate within a single tube two or more channels, each of which is characterized by a different fundamental and/or resonant frequency at which water will oscillate within that tube in a direction approximately parallel to the longitudinal axis of the partitioned tube and each of which is therefore excited by differing wave amplitudes and/or periods, and/or differing ranges of wave amplitudes and/or periods, which result in optimal, maximal, and/or the most energetic discharges of water from the upper aperture of the respective tubes and/or of the constituent channels therein.
Tapered tubes of the current disclosure include, but are not limited to, those which are comprised of collections of, sets of, pluralities of, and/or two or more, constituent tubes, pipes, channels, and/or conduits. For example, an embodiment of the current disclosure incorporates and/or includes a water tube comprised, at least in part, of many pipes bound, fastened, and/or welded together such that the joined collection of constituent pipes in effect constitutes a partitioned tube of larger diameter.
Embodiments of the current disclosure incorporate, include, and/or utilize one or more tapered tubes, and The present disclosure includes embodiments that incorporate, include, and/or utilize any number of water tubes. Embodiments of the current disclosure may also incorporate, include, and/or utilize two or more water tubes that wherein one or more of those water tubes differs from one or more of the other water tubes with respect to diameter, length, included taper angle, cross-sectional shape, volume, and/or any other parameter, dimension, characteristic, and/or attribute. Each of such an embodiment's two or more unequal water tubes will tend to optimally responsive to different wave climates, wave heights, and/or wave periods. An embodiment's use of two or more tubes of differing lengths, included taper angle, volume, etc., may permit the embodiment to extract optimal amounts of energy from a greater range of waves amplitudes and/or periods than might be possible with only a single tube or multiple tubes of identical geometries.
An embodiment of the current disclosure utilizes and/or incorporates two or more tapered tubes. One such embodiment directs a portion of the water ejected by each tube into a common and/or shared water reservoir from which gravitational potential energy and/or rotational kinetic energy is extracted. Another such embodiment directs a portion of the water ejected by each tube into a dedicated and/or tube-specific water reservoir.

Tapered tubes of the current disclosure include, but are not limited to, those which are comprised of tube walls of approximately constant thickness and/or strength; as well as those which are comprised of tube walls of variable, inconsistent, and/or changing, thicknesses and/or strengths (e.g., tubes having thicker walls nearer the buoy (upper hull enclosure) and thinner walls near the bottom of the water tube, may have the advantage of providing an economy of structural material while successfully resisting structural loads).
The current disclosure includes an embodiment in which a water tube has an airfoil-shaped cross-sectional shape (i.e., with respect to a (nominally horizontal) cross-section in a plane normal to a longitudinal axis of the water tube, i.e. parallel to a resting water surface on which the device floats).

Embodiments of the present disclosure incorporate and/or utilize inertial water tubes through which water tends to oscillate and from the upper mouth of which water is occasionally ejected. The ejection of water from the upper mouths of these tubes is facilitated, promoted, enabled, and/or increased (e.g., in volume and/or frequency), by a reduction in the cross-sectional area of the tube proximate to the upper mouth, which constriction serves to excite water in the tube to oscillate. The present disclosure includes embodiments incorporating and/or utilizing any number of water tubes, wherein at least one of an embodiment's water tubes has an inconstant cross-sectional area with respect to sectional planes normal to the longitudinal axis of the inertial water tube, and/or normal to the axis of flow through the inertial water tube (i.e., inconstant “flow-normal” cross-sectional areas). The present disclosure includes embodiments incorporating and/or utilizing inertial water tubes characterized by variations, changes, differences, and/or alterations, in the flow-normal cross-sectional areas of any magnitude, relative or absolute, and of any form, design, or shape.

And an embodiment of the current disclosure utilizes such a pocket of pressurized air as its primary, if not only, source and/or provider of buoyancy. With respect to certain embodiments, the buoyancy of the pressurized accumulator keeps at least a portion of the embodiment floating adjacent to the surface of a body of water, and if a wall of the pressurized accumulator were to be punctured and/or the air within it released to the atmosphere, water could fill the accumulator and the embodiment would sink.

The coupling of such an effluent-generated thrust propulsion system with a device, mechanism, structure, feature, system, and/or module, that rotates the embodiments about their nominally vertical, longitudinal axes, and/or the utilization of two or more points of effluent-generated thrust propulsion which can be differentially controlled, allows such embodiments to not only be propelled, but also to be steered along a specific, adjustable, controllable, and/or desirable direction and/or course. The many devices, mechanisms, structures, features, systems, and/or modules, that permit such embodiments to be rotated about vertical axes, includes, but is not limited to: additional discharges of pressurized water from raised and/or pressurized water reservoirs from apertures, pipes, channels, and/or orifices, that are oriented so as to generate an at least partially tangential thrust to the embodiments; a rudder positioned adjacent to the mouth, aperture, and/or orifice, from which the thrust-generating turbine discharge is returned to the body of water; a rudder positioned at any location on the device in contact with, or beneath the surface of, the body of water on which the embodiments float; and/or a rotatable and/or adjustable sail.
Some embodiments of the present disclosure use one or more antennas, and/or one or more arrays of antennas, to facilitate communication, coordination, and/or the transfer of data, with a land-based receiver, one or more other embodiments and/or instances of the same embodiment, boats, submarines, buoys, airborne drones, surface water drones, submerged drones, satellites, and/or other receivers and/or transmitters utilizing one or more antennas.
Embodiments of the present disclosure utilize one or more types of antennas including, but not limited to, the following:
Embodiments of the present disclosure utilize one or more types of antenna arrays including, but not limited to, the following:
An embodiment of the current disclosure utilizes and/or incorporates at least one phased array antenna (and/or other type of antenna) across and/or over at least one broad area of the embodiment's upper surfaces, walls, and/or decks.
An embodiment of the present disclosure utilizes a phased array of antennas, e.g., dipole antennas, arrayed across an upper exterior surface of the embodiment. Because such a phased array is deployed across such a broad and/or expansive area and/or array, the embodiment is provided with the opportunity to achieve a highly resolved directionality and a significant and/or optimized degree of signal gain.
An embodiment of the present disclosure utilizes a phased array of antennas deployed across a broad, nominally horizontal upper exterior surface of the embodiment, which permits the phased array and/or the embodiment to achieve an optimized signal strength, signal-to-noise ratio, and data exchange rate, with respect to electromagnetically-mediated communications and/or exchanges of signals and/or data with a satellite. Such a capability is useful to a self-propelled embodiment that executes computing tasks received from a remote computer or computing network by satellite, and that returns computing results to a remote computer or computing network by satellite.
An embodiment of the present disclosure utilizes a phased array of antennas deployed across a broad, at least partially vertical lateral exterior surface of the embodiment, e.g., such as one or more sides of the embodiment, and this phased-array deployment facilitates the embodiment's communications and/or to exchanges of data with remote antennas, e.g., those of other devices and/or terrestrial antennas, and with any associated and/or linked computers or computing networks. Such remote antennas might be associated with, and/or integrated within, a variety of systems, stations, and/or locations, including, but not limited to terrestrial stations, airborne drones, ocean-going surface drone vessels, ocean-going submerged drone vessels, piloted aircraft, and satellites.
The current disclosure includes, but is not limited to, embodiments that incorporate, include, and/or utilize, phased arrays comprised of individual antennas with any relative and/or absolute orientation relative to the rest of the embodiment. The scope includes embodiments in incorporating, including, and/or utilizing, phased arrays comprised of individual antennas (of which the phased array is comprised) having any orientation relative to a respective embodiment, and having any orientation with respect to one another (e.g., parallel, normal, radial, random, etc.).
The current disclosure includes, but is not limited to, embodiments that incorporate, include, and/or utilize, phased arrays of any size, phased arrays comprised of any number of individual and/or constituent antennas, and/or phased arrays comprised of constituent antennas of any size. The current disclosure includes, but is not limited to, embodiments that incorporate, include, and/or utilize, phased arrays characterized by, and/or capable of, any transmission power, signal strength, and/or gain, and/or any degree of signal amplification with respect to received signals.
An embodiment of the present disclosure incorporates on an upper exterior deck and/or surface a phased array utilizing digital beamforming, and also utilizing gyroscopes and/or accelerometers to track changes in the orientation of the embodiment in order to reduce the latency between such changes and corresponding corrections to the gain and/or directionality of the phased array's beam, e.g., to preserve an optimal beam orientation with respect to a satellite.
An embodiment of the present disclosure incorporates on an upper exterior deck and/or surface a phased array transmitting and receiving electromagnetic radiation at least two frequencies, wherein the beamwidth of a first frequency is significantly greater than the beamwidth of a second frequency. Such an embodiment uses the relatively broad beam of the first frequency to localize and track a target receiver and/or transmitter, e.g., a satellite, and to adjust the angular orientation and/or beamwidth of the relatively narrow beam of the second frequency so as to optimize the second beam's gain with respect to the target receiver and/or transmitter.
An embodiment of the present disclosure incorporates dipole antennas attached to the periphery of the buoy and oriented approximately radially about the periphery of an exterior deck of the embodiment (with respect to a vertical longitudinal axis of the embodiment and/or its inertial water tube). The embodiment's dipoles benefit from the proximate ground plane created by the sea and its surface, wherein the sea and/or its surface reflect upward any beam lobe that might have otherwise been directed downward, thus increasing the gain of the upward beam.
An embodiment of the present disclosure stores at least a portion of the electrical energy (and/or another form(s) of energy) that it extracts from ambient waves in an energy storage device, component, and/or system. Embodiments of the present disclosure include, incorporate, and/or utilize, energy storage devices, components, and/or systems, including, but not limited to:
An embodiment of the present disclosure utilizes at least a portion of the energy that it stores in order to provide approximately steady and/or continuous electrical power to at least a portion of the computers and/or computer networks contained therein. An embodiment of the present disclosure responds to a diminution and/or reduction in the rate at which it produces and/or generates electrical power (e.g., in response to suboptimal wave conditions) by incrementally shutting down computers and/or computer networks therein, and/or adjusting the clock frequency of computers or integrated circuits contained therein, and/or by adjusting the duty cycle and/or CPU consumption of computational processes being run on one or more computers of the embodiment, e.g. by periodically pausing and restarting such processes, or by adjusting the scheduling of such processes by the kernel of an operating system of one or more computers of the embodiment. An embodiment of the present disclosure responds to a resumption and/or return of a nominal rate electrical power production and/or generation (e.g., in response to a resumption of optimal wave conditions) by incrementally turning on computers and/or computer networks therein.
An embodiment of the present disclosure activates and deactivates subsets of its computers, and/or changes a clock frequency (clock rate) of an integrated circuit thereof (e.g. a CPU, GPU, or ASIC thereof), thereby changing and/or adjusting the number and/or percentage of its computers that are active at any given time, and/or the percentage of available computational power that is available at any given time, so as to correspondingly change and/or adjust the amount of electrical power required by those computers (i.e., the “electrical load”), in response to changes in wave conditions, and/or changes in the amount of electrical power generated by its power takeoff, so as to match the amount of power being consumed by the computers to the amount being generated (i.e., to match the generation power level to the load).
An embodiment of the present disclosure incorporates, and/or utilizes components and/or mechanisms, including, but not limited to: batteries, capacitors, springs, flywheels, and/or chemical fuel (e.g. hydrogen) generators and storage mechanisms. These energy storage mechanisms permit the embodiment to store, at least for a short time (e.g. 10-20 seconds), at least a portion of the electrical and/or mechanical energy generated by the embodiment in response to wave motion. Such energy storage may have the beneficial effect of permitting the embodiment to integrate and/or smooth the generated electrical power.
An embodiment of the present disclosure, when tethered to other embodiments and/or devices, may further stabilize its own energy supplies, as well as helping to stabilize the energy supplies of the other tethered devices, by sharing electrical energy, batteries, capacitors, and/or other energy storage means, capacities, components, and/or systems, and/or by sharing and/or distributing generated power, across a power bus and/or grid that it shares with the other tethered devices. This capability and deployment scenario will facilitate the ability of some tethered collections and/or farms of embodiments to potentially utilize a smaller total number of batteries, capacitors, and/or other energy storage means, components, and/or systems, since the sharing of such components, systems, and/or reserves will tend to reduce the amount of energy that any one device will need to store in order to achieve a certain level of stability with respect to local stochastic variations in generated power and/or computing requirements.
An embodiment of the present disclosure incorporates, and/or utilizes, sufficient energy storage means, capacities, components, and/or systems, so that a sufficiently great amount of energy may be thus stored, thereby allowing the embodiment to continue powering a greater number of computers than could be powered without energy storage and/or buffering, i.e., by relying only on the utilization of inconstant, fluctuating, instantaneous levels of generated electrical power. For example, the embodiment is able to store enough power to energize all of its computers for a day in the absence of waves, and is therefore able to avoid reducing its number of active computers during a “lull” in the waves, and to continue energizing them until a nominally energetic wave state resumes.
An embodiment of the present disclosure applies, consumes, and/or utilizes, at least 50% of the electrical power that it generates in order to energize, power, and/or operate, its respective computing devices and/or circuitry. An embodiment of the present disclosure applies, consumes, and/or utilizes, at least 90% of the electrical power that it generates in order to energize, power, and/or operate, its respective computing devices and/or circuitry. An embodiment of the present disclosure applies, consumes, and/or utilizes, at least 99% of the electrical power that it generates in order to energize, power, and/or operate, its respective computing devices and/or circuitry (including CPUs, memory, and/or ASICs).
An embodiment of the present disclosure utilizes a portion of the electrical energy that it generates in order to energize computers that perform computational tasks specified by remote operators, computers, and/or networks, and transmitted to the embodiment, e.g., by satellite. The embodiment, and the computers of which it is comprised, operate with a “power usage effectiveness” (PUE) of no more than 1.1. An embodiment of the present disclosure utilizes a portion of the electrical energy that it generates in order to energize computers that perform computational tasks specified by remote operators, computers, and/or networks, and transmitted to the embodiment, e.g., by satellite. The embodiment, and the computers of which it is comprised, operate with a “power usage effectiveness” (PUE) of no more than 1.01. An embodiment of the present disclosure utilizes a portion of the electrical energy that it generates in order to energize computers that perform computational tasks specified by remote operators, computers, and/or networks, and transmitted to the embodiment, e.g., by satellite. The embodiment, and the computers of which it is comprised, operate with a “power usage effectiveness” (PUE) of no more than 1.001.
An embodiment of the present disclosure turns at least a portion of its computing devices and/or integrated circuits on and off (and/or adjusts their clock rate) so as to at least approximately match the amount of electrical power being generated by the embodiment at any given moment, and/or to match the rate at which the embodiment is extracting energy from the waves that buffet it.
The power profile of a wave energy converter can be irregular, i.e. it can generate large amounts of power for a few seconds, followed by a pause of a few seconds when no power is generated. ASIC chips designed to computing hash values for the “mining” of cryptocurrencies can typically compute many millions of hash values per second. An embodiment of the present disclosure, incorporates, and/or utilizes, energy control circuits that turn on and energize ASICs and/or CPUs when the embodiment is generating power, and de-energize ASICs and/or CPUs when the embodiment is not generating power. An embodiment of the present disclosure, incorporates, and/or utilizes, energy control circuits that energize a quantity of ASICs and/or CPUs that corresponds and/or is proportional to the amount of power that the embodiment is generating at any particular time, and/or adjusts the clock rate or processor load of said ASICs and/or CPUs in a manner approximately proportional to the amount of power that the embodiment is generating at any particular time. In this manner, the amount of power storage and/or buffering equipment required of the embodiment can be reduced. An embodiment of the present disclosure, incorporates, and/or utilizes, computing circuitry that is at least partially energized and de-energized on a second-by-second basis. An embodiment of the present disclosure, incorporates, and/or utilizes, computing circuitry that is at least partially energized and de-energized on a millisecond by millisecond basis.
An embodiment of the present disclosure selects those tasks that it will attempt to compute and/or execute in order to at least approximately match the amount of future computing power and/or computing capacity, and/or the amount of time or energy, required to complete those tasks, with the amount of power and/or energy estimated and/or forecast to be generated by the embodiment at a future time.
An embodiment of the present disclosure turns at least a portion of its computing devices on and off as needed in order to at least approximately match the amount of electrical power that its computers forecast and/or estimate that the embodiment's power take off will generate at a future time. An embodiment of the present disclosure turns at least a portion of its computing devices on and off (or adjusts the clock rate or processor load of integrated circuits) as needed in order to at least approximately match the amount of electrical power that has been forecast and/or estimated by a computer on another embodiment or device, and/or on a computer at a remote location (e.g., a land-based facility), that the embodiment's power take off will generate at a future time.
An embodiment of the present disclosure, when deployed within a farm configuration in which the embodiment, and other embodiments and/or devices, are electrically connected to one another and/or to one or more terrestrial and/or other sources of electrical power, may, e.g. when its power generation exceeds its computing power requirements, send excess generated electrical power to another embodiment, e.g., for storage, or to shore (e.g., to an onshore grid connection). Conversely, an embodiment deployed in such a farm configuration, in which the embodiment, and other embodiments and/or devices, are electrically connected to one another and/or to one or more terrestrial and/or other sources of electrical power, may, when its computing demands require more electrical energy than can be provided through its own conversion of wave energy (e.g. when waves are small), draw energy from one or more of the other embodiments and/or devices to which it is electrically connected, and/or from the one or more terrestrial sources of power to which it is electrically connected so as to continue computing and/or recharge its energy reserves.
An embodiment of the present disclosure facilitates its communication, coordination, and/or its transfer of data, with the respective computing devices and/or circuits of one or more other embodiments and/or devices by means of a common distributed network, e.g. Ethernet, Infiniband, or TCP/IP.
An embodiment of the present disclosure facilitates its communication, coordination, and/or its transfer of data, with the respective computers, circuits, and/or internal and/or physical networks on, and/or incorporated within, one or more other embodiments and/or devices by means of virtual and/or electromagnetic network connections and/or links, e.g. WAN, Wi-Fi, satellite-mediated, radio, microwave, and/or modulated light. The embodiment shares data, programs, and/or otherwise cooperates, with the one or more other embodiments and/or devices without the benefit of a physical (wired) network connection.
An embodiment of the present disclosure transmits, receives, transfers, shares, and/or exchanges, data with one or more other embodiments and/or devices by means of acoustic and/or electrical signals transmitted through the body of water and/or seawater on which they float. By inducing localized sounds, acoustic signals, electrical currents, and/or electrical charges, within the seawater that surrounds it, the embodiment creates acoustic and/or electrical signals in the seawater that travel through the seawater, and/or radiate away from the embodiment within the seawater, and can be detected and/or received by the one or more other embodiments and/or devices. In this way, a two-way exchange of data, as well as broadcasts of data from one embodiment to one or many others can be completed, executed, and/or realized.
When other embodiments and/or devices are so distant from an embodiment of the present disclosure that line-of-sight communication options, e.g. modulated light, are not available, possible, feasible, and/or practical, then the embodiment facilitates its sharing, and/or exchange, of data with those other distant embodiments and/or devices by daisy-chaining, through intermediate embodiments and/or devices, inter-device communications, signals, transmissions, and/or data transfers. Data may be exchanged between two widely separated embodiments through the receipt and re-transmission of data by embodiments and/or devices located at intermediate positions from the originating and target embodiments and/or devices.
An embodiment of the present disclosure transmits, receives, transfers, shares, and/or exchanges, data with receivers at distant locations, e.g., with other embodiments and/or devices, and/or with remote objects, facilities, computers, and/or networks, by means of modulated light and/or “flashes” shined on, and/or reflected or refracted by, atmospheric features, elements, particulates, droplets, etc. An embodiment encodes data (with the encoding preferably including an encryption of the data) into a series of modulated light pulses and/or flashes that are projected into the atmosphere in a direction at least an approximately toward a distant receiver, e.g., toward other embodiments and/or devices, and/or toward remote objects, facilities, computers, and/or networks. The receiver, e.g. through the use of wavelength-specific filters, and/or temporally specific frequency filters, will then detect at least a portion of the transmitted light pulses and decode the encoded data. The return of data by the receiver to the embodiment is accomplished in the same or similar manner.
Such a “reflected and/or refracted and light-modulated” data stream can be made specific to at least a particular wavelength, range of wavelengths, pulse frequency, and/or range of pulse frequencies. By such a data communication scheme and/or process, an individual embodiment can be configured to transmit data to one or more individual other embodiments and/or devices (e.g. on separate wavelength-specific channels), and/or to a plurality of other embodiments and/or devices. The embodiment can be configured to receive data from one or more individual other embodiments and/or devices (e.g. on separate wavelength-specific channels), and/or from a plurality of other embodiments and/or devices.
An embodiment of the present disclosure includes a cable that is directly and/or indirectly connected to at least one of the embodiment's computers and/or other electronic devices, components, networks, and/or systems. One end of the cable is suspended from the embodiment adjacent to the surface of the body of water on which the embodiment floats. When a suitably configured vessel, e.g., an unmanned autonomous vessel, approaches the embodiment, it may secure and connect to the free end of that cable, and thereafter may communicate through that cable with the computers and/or other electronic devices, components, and/or systems, on board the embodiment to which the cable is connected. Through the embodiment's “exterior data access cable”, another suitably configured vessel can exchange copious amounts of data with computers and/or other electronic devices, components, and/or systems, on the embodiment, e.g., in order to download the results of a calculation and/or simulation performed on the embodiment, and/or to upload a body of data and/or applications to be executed in order to perform a calculation.
Embodiments of the present disclosure achieve this remote data exchange capability by means of exterior data access cables comprising, at least in part, cables of known types, including, but not limited to, the following:
Embodiments of the present disclosure may exchange data with other computers, vessels, networks, data-relay stations, and/or data repositories, by means of communication technologies including, but not limited to, the following types:
Embodiments of the present disclosure may exchange data with other computers, vessels, networks, data-relay stations, and/or data repositories, by means of suitably equipped communication intermediaries and/or relays including, but not limited to, the following types:
The current disclosure includes embodiments in which at least one “pitch-inhibiting” weight is suspended beneath and/or from, and/or attached to a lower portion of, one or more of the water tubes of the respective embodiments by flexible cables and/or rigid struts and/or other structures. When the orientation of a nominally vertical longitudinal axis of those embodiments deviates from vertical, and/or from being normal with and/or to the resting, nominal surface of the body of water on which each respective embodiment floats, then the downward gravitational force of the weight is imparted to the bottom of the water tube of the respective embodiments, and/or to the bottom of the buoy and/or pressurized reservoir of the respective embodiments, thereby creating a restoring torque. When a pitch-inhibiting weight is suspended beneath and/or from, and/or attached to a lower portion of, two or more water tubes, then a pitching motion of the respective embodiment causes the pitch-inhibiting weight to impart a downward force to the bottom of the most raised tube (i.e., the tube with the least draft), thereby creating a restoring torque.
The current disclosure includes embodiments in which various “water ballast chambers,” compartments, voids, spaces, and/or containers, within the embodiment may be filled with, and/or emptied of, water to a desired degree, thereby altering the average density of the embodiment, and its average depth (i.e., waterline) in the water on which it floats. In many embodiments, the water reservoir into which water is added from ejections from the water tube serves as a water ballast chamber.
By emptying water from one or more of these water ballast chambers, an embodiment can reduce its average density and rise up to a shallower average depth, and/or lower its waterline, thereby projecting its upper portions out of the water and above potentially damaging storm waves and/or surges. In some embodiments, a turbine or flow governor of the embodiment is controlled to change a flow rate of water from the embodiment, to increase or decrease the amount of water in a water reservoir of the embodiment, causing the average density of the embodiment to increase or decrease.
By increasing the volume of water in one or more of these water ballast chambers or water reservoirs, an embodiment can increase its average density and sink down to a greater average depth, and/or raise its waterline, for example, a depth in which it can become more or less responsive to the waves passing beneath and/or around it, thereby increasing the amount of power it is able to extract from those waves, or limiting the amount of energy absorbed from those waves (e.g. to provide additional structural protection).
An embodiment of the current disclosure utilizes an elevated reservoir in which to store water ejected from its inertial water tube. Another embodiment of the current disclosure utilizes a pressurized reservoir in which to store water ejected from its inertial water tube. The reservoirs of both of these embodiments can be equipped with respective valves, that when actuated by the embodiment's control system, directly discharge water from the respective reservoirs and into the body of water on which the embodiment floats, thereby at least partially bypassing each respective embodiment's nominal discharge conduit or tube (i.e. that conduit or tube which contains, and/or incorporates, a water turbine or other flow governor).
An embodiment of the current disclosure utilizes a reservoir in which to store water ejected from its inertial water tube. And, the embodiment utilizes a second reservoir utilized for the creation of ballast. That ballast is comprised, at least in part, of water, and a pump, when appropriately actuated by the embodiment's control system, will pump additional water from the body of water on which the embodiment floats and into the ballast reservoir, thereby increasing the mass and inertia, of the embodiment. That pump (and/or a second pump) when appropriately actuated by the embodiment's control system, will pump additional water out of the ballast reservoir and back into the body of water on which the embodiment floats, thereby decreasing the mass and inertia, of the embodiment.
The current disclosure includes embodiments that are capable of adjusting their included mass and/or inertia and/or average density by any and all means, methods, schemes, technologies, systems, and/or modules, including controlling the amount of water in an included water reservoir fed by ejections from a wave-driven inertial water tube, and/or one or more ballast compartments supplied by water by other means besides ejections from a wave-driven inertial water tube.
The current disclosure includes embodiments in which the effective mass of each embodiment is augmented and/or adjusted, at least in part, through the addition and/or removal of water from within one or more chambers or voids within the embodiments.
An embodiment holds water within the embodiment's buoy or buoyant structure, e.g., in a chamber separate from its water reservoir. An embodiment holds water within the hollow wall of its water tube, e.g., within the gap between the water tube's inner wall and its outer wall wherein the inner wall is a tubular structure approximately coaxial with the tubular outer wall. An embodiment holds water within a chamber, container, and/or void, adjacent to, and/or embedded within, an upper surface of the buoy, the water tube, and/or another part or portion of the embodiment.
The current disclosure includes embodiments in which the inherent mass of each of those embodiments is augmented, at least in part, through the addition of sand, gravel, and/or some other granular or powdered hard materials. This material also includes, but is not limited to, dirt, rocks, crushed cement, bricks, and/or other heavy and/or scrap material, e.g., such as discarded or waste materials that are available for recycling.
The current disclosure includes embodiments in which the inherent mass of each of those embodiments is augmented, at least in part, through the addition of cement and/or cementitious materials.
The current disclosure includes embodiments in which the inherent mass of each of those embodiments is augmented, at least in part, through the addition of a material that is “loose” and/or able to be shoveled, poured, and/or imported to the embodiment. This can include, but is not limited to, aggregate materials.
Some embodiments of the present disclosure float freely, and/or “drift,” adjacent to a surface of water in a passive manner which results in their movement in response to wind, waves, currents, tides, etc. Some embodiments are anchored and/or moored so as to retain an approximately constant position relative to an underlying position on the seafloor. And, some embodiments are self-propelled, and/or capable of exploiting natural movements of air and/or water to move in a chosen, deliberate, calculated, and/or selected direction, at least to an approximate degree.
Some embodiments of the present disclosure are self-propelled and/or capable of exploiting natural movements of air and/or water so as to change their positions in at least a somewhat controlled manner. Self-propelled embodiments may achieve their directed motions by means including, but not limited to discharges of captured water (e.g., from their respective reservoirs), rigid sails, ducted fans, propellers, sea anchors, Flettner rotors, sea anchors, and/or drogue anchors.
Some embodiments of the present disclosure are deployed so as to be free-floating and so as to drift with the ambient winds, currents, and/or other environmental influences that will affect and/or alter their geospatial locations.
Some embodiments of the present disclosure are deployed such that individual devices are anchored and/or moored (e.g. to the seafloor) so as to remain approximately stationary and/or to remain at an approximately constant geospatial position. Some embodiments of the present disclosure which are anchored and/or moored are anchored and/or moored proximate to other such devices and may even be moored to one another. These embodiments may be deployed in “farms” and, of those embodiments which utilize a portion of their power to perform calculations, their respective computers may be directly and/or indirectly interconnected and/or networked such that they may interact, e.g. when cooperating to complete various computing tasks. The computing embodiments deployed in such farms may communicate with computers and/or networks on land by means of one or more subsea data transmission cables, including, but not limited to: fiber optic cables, LAN cables, Ethernet cables, and/or other electrical cables. The computing embodiments deployed in such farms may communicate with computers and/or networks on land by means of one or more indirect devices, methods, and/or means, including, but not limited to: Wi-Fi, radio, microwave, pulsed and/or modulated laser light, pulsed and/or modulated LED-generated light, and/or satellite-enabled communication.
Some computing embodiments of the present disclosure which drift and/or are self-propelled, may directly and/or indirectly interconnect their computers so that they may interact, e.g. when cooperating to complete various computing tasks. For example, drifting devices may act as clusters within a larger virtual cluster network so as to cooperatively complete computing tasks that are larger than individual devices can individually complete. Self-propelled devices, regardless of their respective device-specific applications, may travel the seas together in relatively close proximity to one another, exchanging information via radio, satellite, and/or other indirect means and/or channels, though not directly and/or physically connected (except by the water on which they all float).
Drifting, and/or self-propelled, computing embodiments may communicate with computers and/or networks on land, and/or with each other, by means of one or more indirect devices, methods, and/or means, including, but not limited to: radio, microwave, pulsed and/or modulated laser light, pulsed and/or modulated LED-generated light, and/or satellite-enabled communication.
Some embodiments of the present disclosure are deployed so as to be “virtually” interconnected to one or more other devices (e.g. by Wi-Fi, radio, microwave, modulated light, satellite links, etc.), and to drift together as a loosely-coupled group driven by the ambient winds, currents, and/or other environmental influences that will affect and/or alter their respective geolocations.
Some embodiments of the present disclosure are deployed so as to be tethered, and to be directly inter-connected, to one or more other devices, wherein one or more of the tethered devices are anchored and/or moored (e.g. to the seafloor), and wherein one or more of the tethered devices may not be anchored, but only tethered to other devices, such that the tethered group of devices remain approximately stationary, thereby limiting the range of motion and/or position of the entire tethered assembly.
Some embodiments, when directly and/or indirectly inter-connected with one or more other devices, whether drifting or anchored, will link their respective computers and/or computing networks, e.g. by means of satellite-mediated inter-device communications of data, so as to act, behave, cooperate, and/or compute, as subsets of a larger, integrated, and/or inter-connected set of computers. Such inter-connected and/or cooperating devices may utilize, and/or assign to, a single device (or subset of the inter-connected group of devices) to be responsible for a specific portion, part, and/or subset, of the system-level calculations, estimates, scheduling, data transmissions, etc., on which the group of devices depends.
The current disclosure optimizes the harvesting of energy from ocean waves with a technology that has the potential to be highly reliable, long-lived, and cost effective.
Embodiments of the current disclosure offer many advantages over the prior art, including, but not limited to the ability to capture and convert wave energy with a simple and robust device. For example, embodiments capturing water ejected from their respective tapered tubes within respective elevated and/or pressurized reservoirs, can incorporate, as their only moving parts, a water turbine rigidly and rotatably connected to a generator, or can incorporate no moving parts in the case of the use of a magnetohydrodynamic generator or another flow governor that converts water pressure and flow directly to electrical energy with no moving parts. Such embodiments can operate without the need for valves, motors, and/or other components which might require maintenance or replacement.
Embodiments of the current disclosure can operate far from shore where wave resources are more energetic and consistent, thereby providing those embodiments with greater capacity factors and efficiencies, and with relatively lower costs of energy.
Embodiments of the current disclosure can operate far from shore, in the absence of moorings to the seafloor and connections to subsea power cables, thereby avoiding the costs of deploying such seafloor moorings (and the environmental damage that can result during such deployments), the costs of deploying such subsea power cables, and the costly delays associated with the arduous process of gaining the permits, licenses, and/or other permissions required for deployments that are moored to the seafloor and connected to subsea power cables.
If the electrical power generated by a wave-energy converting device is to be transmitted to land, e.g. where it might be added to an electrical grid, then that power must have a channel, method, and/or means, with which to do so. Many developers of wave energy devices choose to use subsea electrical power cables to transmit the power generated by anchored farms of their devices to shore. However, these cables are expensive. Their deployment (e.g. their burial in the seafloor) is also expensive. And, the anchoring and/or mooring of a farm of such wave energy devices close to shore can be difficult and expensive and can disrupt delicate subsea ecosystems.
The current disclosure allows wave energy devices to make good use of the electrical power that they generate without transmitting it to land. And, because disclosed embodiments are free to operate far from land, they are also able to be deployed where waves are most consistent, and of optimal energies.
While the current disclosure does not preclude the anchoring of the disclosed devices, it nevertheless discloses embodiments that make good use of the electrical power that they generate without being anchored and/or moored to the seafloor, and without a connection to an electrical cable able to transmit the power they generate back to shore.
Free-floating embodiments of the current disclosure can be placed in the water (at appropriate locations) immediately following their fabrication, and soon thereafter, if not immediately, begin operating and generating revenues, e.g., consuming their own generated electrical power in order to achieve onboard production of useful products and/or services. Self-propelled embodiments of the current disclosure can be placed in the water at a greater variety of locations, and then propel themselves to optimal energy-harvesting locations, immediately following their fabrication.
An embodiment of the current disclosure utilizes and/or incorporates computing devices that consume at least a portion of the electrical energy generated by the embodiment in response to wave action in order to perform computations transmitted to it from a remote source (i.e., from a source not physically—rigidly or flexibly—connected to the embodiment) such as via encoded electromagnetic transmissions from a satellite or other remote antenna of executable codes and/or data and/or programs and/or instructions. A substantial portion of the electrical power generated by the embodiment in response to wave action is used to energize the embodiment's cluster(s) of computers, at least some of the time.

At least a portion of the heat generated by the embodiment's computers is transmitted (e.g. passively and/or conductively) to the water on which the embodiment floats, and/or to the air surrounding the embodiment.
Much, if not all, of the energy imparted to computational devices within an embodiment of the present disclosure will become heat. And, excessive levels of heat might damage or impair those computational devices and/or adjacent electronics, systems, structures, modules, and/or parts of the embodiment. Therefore, it is prudent for an embodiment to remove heat from its “active” computational devices as quickly and/or efficiently as possible, and/or at least quickly enough to avoid excessive heating of the computational devices.
An embodiment of the present disclosure facilitates the passive convective cooling of at least some of its computational devices, and/or of the ambient environments of those computation devices. An embodiment of the present disclosure actively removes heat from its computational devices, and/or from the ambient environments of those computational devices.
An embodiment of the present disclosure passively cools its computing devices by facilitating the convective and/or conductive transmission of heat from its computing devices and/or their environment to the water on which the device floats, e.g. through a thermally conductive wall, and/or fins or heat baffles, separating the devices from the water.
In an embodiment, the conduction of heat from computing devices takes place via a conductive and/or metal wall in a conduit through which water flows from a reservoir of the embodiment to a turbine or magnetohydrodynamic generator of the embodiment. In an embodiment, the conduction of heat from computing devices takes place via a conductive and/or metal wall in a conduit through which water flows from a turbine or magnetohydrodynamic generator of the embodiment to the body of water on which the embodiment floats. In either of these cases, heat can be conducted to the conductive and/or metal wall by the evaporation and/or boiling of a liquid substance in which computing circuits of the embodiment are immersed, followed by condensation of said substance on said wall.
An embodiment of the present disclosure passively cools its computing devices by facilitating the convective and/or conductive transmission of heat from its computing devices and/or their environment to the air above the water on which the device floats, e.g. through a thermally conductive wall, and/or fins or heat baffles, separating the devices from the air.
An embodiment of the present disclosure actively cools its computing devices by means of a heat exchanger that absorbs heat from the computing devices and/or their environment, and carries it to a heat exchanger in thermal contact with the water on which the device floats and/or in thermal contact with the air above that water. Such thermal contact may be the result of direct exposure of the exchanger with the water and/or air, or it may be the result of indirect exposure of the exchanger with the water and/or air by means of the exchanger's direct contact with a wall or other surface in direct or indirect contact with the water and/or air.
An embodiment of the present disclosure passively cools its computing devices, and/or of the ambient environment of its computing devices, by providing a thermally conductive connection between the computing devices and the water on which the embodiment floats and/or the air outside the embodiment. An embodiment promotes this conduction of heat from the computing devices to the ambient water and/or air by using “fins” and/or other means of increasing and/or maximizing the surface area of the conductive surface in contact with the water and/or air. An embodiment promotes this conduction of heat from its computing devices to the ambient water by using metallic (e.g., copper and/or copper/nickel) heatsink poles and/or plates extending into the water and/or air outside the embodiments, and/or into the chamber(s) in which at least a portion of the embodiment's computing devices are located.
The computers of an embodiment of the present disclosure are positioned, located, and/or operated, within sealed chambers containing air, nitrogen, and/or another gas or gases. The computers of an embodiment of the present disclosure are positioned, located, and/or operated, within chambers into which air, nitrogen, and/or another gas or gases, are pumped.
Because a computing device operating in an air environment (e.g. inside a compartment or module on and/or within an embodiment of the present disclosure) may not transmit heat with sufficient efficiency to prevent and/or preclude an overheating of the computing device, an embodiment of the present disclosure incorporates, includes, and/or utilizes, a thermally conductive fluid and/or gas to facilitate the passage of heat from the various components (e.g. the CPUs) within its computing devices to the ambient air or water proximate to the embodiment thereby reducing the risk of overheating, damaging, and/or destroying some, if not all, of its computing devices.
An embodiment of the present disclosure promotes the conduction of heat from its computing devices to the ambient air and/or water by immersing, surrounding, bathing, and/or spraying, the computing devices with and/or in a thermally conductive fluid and/or gas. The thermally conductive fluid and/or gas is ideally not electrically conductive, as an electrically conductive might tend to short-circuit, damage, and/or destroy, the computing devices. The thermally conductive fluid and/or gas ideally has a high heat capacity that allows it to absorb substantial heat without experiencing a substantial increase in its own temperature. The thermally conductive fluid and/or gas carries at least a portion of the heat generated and/or produced by at least some of the computing devices to one or more thermally conductive interfaces and/or conduits through which at least a portion of the heat may pass from the fluid and/or gas to the ambient air or water proximate to the embodiment. In some embodiments, said thermally conductive fluid has a boiling point sufficiently low that said fluid boils when it bathes operational computing devices of the embodiment.
An embodiment of the present disclosure may cool its computing systems, and/or other heat-generating components and/or systems, by means, systems, modules, components, and/or devices, the include, but are not limited to, the following:
A significant advantage of embodiments of the present disclosure is that a large number of computing devices can be deployed within, among, and/or between a large number of embodiments, such that a relatively large number of computing devices are partitioned into a large number of relatively small embodiment-specific groups, which, in addition to being powered, at least in part, by the energy that each respective embodiment extracts from the environment proximate to the embodiment, are also immediately adjacent, and/or proximate, to a heat sink characterized by a relatively cool temperature and a relatively large heat capacity, i.e. the sea, and the air, atmosphere, and/or wind that flows above it. By deploying relatively small numbers of computing devices in self-powered and passively cooled autonomous units, environmental energy is used with maximal efficiency (e.g. without suffering the losses and costs associated with transmitting the power to shore), and the requisite cooling of those computing devices is accomplished with minimal, if any, expenditure of additional energy. Embodiments of current disclosure permit a graceful and efficient scaling of computing and/or computing networks through the iterative fabrication and deployment of relatively simple and cost-effective self-powered, self-cooling, computing modules.
By contrast, the concentration of larger numbers of computing devices, e.g. the number of computing devices that might be associated with hundreds or thousands of embodiments of the present disclosure, requires that a significant amount of power be generated remotely and transmitted to the concentrated collection(s) of computing devices (e.g., in a server farm or data warehouse), thereby increasing the costs and incidental losses of the energy consumed. Furthermore, the concentration of larger numbers of computing devices, as in a server farm, requires a relatively large and concentrated amount of heat to be actively and energetically removed from the many computing devices co-located in a relatively small space, and/or volume, which typically requires a significant expenditure of capital and additional energy.
An embodiment of the present disclosure interconnects at least some of its computing devices with, and/or within, a network in which each of a plurality of the computing devices are assigned, and/or associated with, a unique internet, and/or “IP” address. An embodiment of the present disclosure interconnects at least some of its computing devices with, and/or within, a network in which a plurality of the computing devices are assigned, and/or associated with, a unique local subnet IP address.
An embodiment of the present disclosure interconnects at least some of its computing devices with, and/or within, a network that incorporates, includes, and/or utilizes, a router.
An embodiment of the present disclosure interconnects at least some of its computing devices with, and/or within, a network that incorporates, includes, and/or utilizes, a modem.
An embodiment of the present disclosure interconnects at least some of its computing devices with, and/or within, a network that incorporates, includes, and/or utilizes, a “storage area network.”
The current disclosure includes embodiments in which pluralities of computers, computing systems, computational systems, servers, computing networks, data processing systems, and/or information processing systems, incorporated therein, are cooled by methods, mechanisms, processes, systems, modules, and/or devices, that include, but are not limited to, the following:
By sequestering clusters of computers within independent self-powered, free-floating, devices, the numbers of computers (i.e. the numbers of clusters) made available for computational work, and/or the processing of computing tasks, can be scaled with relative ease, e.g. there are no obvious barriers, costs, and/or consequences, associated with an increase in the numbers of such sequestered clusters.
The energy efficiency of virtually interconnected and/or cooperating sets of collocated computers can be discussed in terms of “power usage effectiveness” or “PUE.” PUE=(Total Computing Facility Power)/(Total Computing Equipment Power).
Because large terrestrial and/or land-based clusters of computers require the expenditure of energy not just to energize the computers themselves, but also for requirements such as: cooling, lighting, environmental considerations for staff, etc., their PUEs are typically estimated to be about 1.2. An ideal PUE would be 1.0, which would mean that all electrical power consumed, was consumed by the computers during their execution of their respective computing tasks, and, by extension, no electrical power was “wasted” doing anything else.
Many embodiments of the disclosed device utilize passive conductive cooling of their computers, which, because it is passive, consumes no electrical power. And, because the disclosed devices are typically autonomous and/or unmanned, many embodiments utilize close to 100% of the electrical power that they generate energizing their respective computers and providing them with the energy that they need to complete their respective computing tasks. Thus, many embodiments of the disclosed device will have a PUE approaching 1.0, i.e. a “perfect” power usage effectiveness, at least net of any losses due to temporary buffering or storage of power.
Also, because the computers stored and operated within embodiments of the present disclosure are located on devices that are floating on a body of water (e.g. on the sea far from shore), they provide significant computing power without requiring a concomitant dedication of a significant area of land. This potentially frees land that might otherwise have been used to house such computing clusters, so that it might instead be used for farming, homes, parks, etc.
Some embodiments of the present disclosure, when deployed in anchored farms of devices, will send electricity back to an onshore electrical power grid via a subsea electrical power cable. However, when the electrical demands of that terrestrial grid are not high, and/or the price of electrical power sold into that grid is too low, then some or all of the devices in the farm may perform other tasks such as performing computations, such as Bitcoin mining and/or arbitrary or custom computational tasks for third parties, in order to generate revenue and/or profits.
Some might regard the history of computing as having taught that progress, especially with respect to the scaling of computing, is often a consequence of an underlying progress in the discovery and/or invention of new ways to “decouple” the components, and the constituent tasks, on which large-scale computing relies, from the overhead and/or support requirements needed to support large “monolithic” collections of computers. Embodiments of the present disclosure achieve a decoupling of computing networks from the traditional concentrated land-based deployments which tend to suffer from a number of inefficiencies.
The current disclosure offers many potential benefits, including, but not limited to a decoupling of computing power (e.g. available CPUs and/or instructions per second) from the typically correlated supporting and/or enabling requirements, e.g., such as those associated with the construction, operation, and/or maintenance, of data centers and/or server farms.
These requirements include the need that sufficient electrical power be provided to energize a large number of computers. In order to transmit large amounts of electrical power into concentrated collections of computers, it is typically necessary to bring the power to the collections of computers at a high voltage and/or a high current. However, since individual computers, computing devices, and/or computing circuits, require electrical power that is typically of a lower voltage and/or current, it is often necessary and/or preferred to partition the high-energy electrical power into multiple circuits of lower-energy power. These changes in voltage and/or current can result in some loss of energy and/or efficiency.
These requirements include the need to remove heat, and/or introduce cooling, fast enough to compensate for the significant amounts of heat that are generated by highly concentrated and extensive collections of electrically powered computing devices. Such cooling is relatively energy intensive, e.g. significant electrically powered refrigeration, fans, pumped liquid heat exchangers, etc.
Embodiments of the present disclosure obtain relatively small amounts of electrical power from water, and/or ocean, waves and utilize that electrical power to energize a relatively small number of computing devices. By contrast with large, highly-concentrated, collections of computers, the computers within embodiments of the current disclosure are able to be energized with electrical power that, at least approximately, matches electrical requirements of the computers, i.e. there is no need to transmit highly-energetic electrical power from distant sources before reducing that power down to voltages and/or currents that are compatible with the computers to be energized.
Some embodiments of the present disclosure achieve and/or satisfy all of their cooling requirements through purely passive and convective and/or conductive cooling. Thermally conductive walls and/or pathways facilitate the natural transmission of heat from the computing devices to the air and/or water outside the device. A relatively smaller number of devices means relatively less heat is generated. And, the proximity of a heat sink of significant capacity (i.e. the water on which the device floats) means that the removal of these relatively small amounts of heat conductively and/or convectively is achieved with great efficiency and in the absence of any additional expenditures of energy.
The current disclosure increases the modularity of clusters of computing devices by not only isolating them physically, but also by powering them independently and autonomously, and by cooling them passively. Through the creation and deployment of additional self-powered computing buoys, a computing capability can be scaled in an approximately linear fashion, typically, if not always, without the non-linear and/or exponential support requirements and/or consequences, e.g. cooling, that might otherwise limit an ability to grow a less modular architecture and/or embodiment of computing resources.
The current disclosure provides a useful application for wave-energy conversion devices that requires significantly lower capital expenditures and/or less infrastructure. For instance, a free-floating and/or drifting device of the current disclosure can continuously complete computational tasks, such as calculating Bitcoin block headers and/or nonce values, while floating freely in very deep water (e.g. 3 miles deep) in the middle of an ocean, hundreds or thousands of miles from shore. Such an application does not depend upon, nor require, a subsea power cable to send electrical power to shore. It does not require extensive mooring and/or the deployment of numerous anchors in order to fix the position of a device, e.g. so that it can be linked to a subsea power cable.
Embodiments of the present disclosure support, perform, and/or execute computing tasks of an arbitrary nature. Embodiments of the present disclosure incorporate and/or utilize computing circuits specialized for the execution of specific types of computing tasks, such as the “mining” of cryptocurrencies such as Bitcoin. An embodiment's receipt of a computational task, and its return of a computational result, may be accomplished through the transmission of data across satellite links, fiber optic cables, LAN cables, radio, modulated light, microwaves, and/or any other channel, link, connection, and/or network. Computationally intensive tasks may be shared, and/or cooperatively executed or completed, across multiple embodiments.

An embodiment of the present disclosure generates fees, and/or the owner of an embodiment of the present disclosure calculates fees, for at least some of the “on-demand” computational tasks that the embodiment executes based on attributes that include, but are not limited to: size (e.g. in bytes) of program and/or data executed, size (e.g. in bytes) of data created during program execution and/or returned to the owner of the program, number of computing cycles (number of computational operations) consumed during program execution, amounts of RAM, and/or hard disk space, utilized during program execution, other computing resources, such as GPUs, required for program execution, and the amount of electrical power consumed during and/or by a program's execution.

An embodiment of the present disclosure stops execution of a sufficient number of its most-recently started computational tasks, and/or those tasks with the greatest estimated remaining execution times, and powers down the corresponding computing devices and/or circuits, e.g., to provide, and/or ensure, sufficient power to complete the computation of the remaining tasks using the still-active computing devices and/or circuits, when the embodiment determines that the level of its power generation has decreased, and the continued and/or continuous operation of its currently “active” computing devices and/or circuits can no longer be sustained
An embodiment of the present disclosure transmits the results of a completed task to a remote source and/or server (e.g. the remote source and/or server from which the task originated). After receipt and/or validation of the completed-task results, a remote source and/or server broadcasts to every one of a collection, cohort, and/or set of cooperating embodiments, which (would have been expected to have) received the now-completed task, a message and/or signal to indicate that the task has been completed. Each of the embodiments receiving the “task-completed” message and/or signal then removes that task from its task queue and terminates execution of the task if the execution of the task is in progress.
An embodiment of the present disclosure receives the same task received by a plurality of embodiments, and may elect to place the task in its task queue, thereby deferring and/or delaying task execution, and/or it may elect to execute the task when sufficient computing resources and/or energy are available.
In addition to the results of a task, an embodiment also returns to a remote source and/or server, information that is sufficient to allow the benefactor of the task's execution to be charged and/or billed an amount of money consistent with a payment contract. Such “billing-relevant information” might include, but is not limited to, the following:

A global task controlling and/or coordinating computer and/or server may use such task-execution-specific data in order to forecast which tasks are likely to be successfully completed by a future time. And, if the likelihood of a particular task's completion by a future time is sufficiently great then other embodiments of the present disclosure which have been notified of the task at an earlier time, and which are potentially storing the task in their respective task queues, may be notified of that task's likely completion by an embodiment. The notified embodiments may then elect to reduce the priority of the task, or to remove it from their task queues.

A free-floating embodiment of the present disclosure, as well as an anchored and/or moored embodiment of the present disclosure, neither of which are directly connected to land by means of a cable, utilize one or more indirect network communication links, including, but not limited to: satellite, Wi-Fi, radio, microwave, modulated light (e.g. laser, LED).
An embodiment of the present disclosure communicates with other embodiments, devices, and/or terrestrial data transmission and/or exchange networks, by transmitting data to a remote receiver by means of modulated light (e.g. laser or LED) which is limited to one or more specific wavelengths and/or ranges of wavelengths. The sensitivity of the remote receiver is then improved through the receiver's use of complementary filter(s) to exclude wavelengths of light outside the one or more specific wavelengths and/or ranges of wavelengths used by the embodiment. Another remote receiver with which the embodiment communicates utilizes multiple such wavelength-specific filters, e.g. utilizing a specific filter to communicate with a specific receiver, so as to limit and/or discriminate its receipt of data to that transmitted from one or more specific remote sources at a time and/or from among many such remote sources, each of which, and/or each subset of which, utilizes a specific wavelength(s) and/or range(s) of wavelengths.

In some deployments of some embodiments of the present disclosure, a satellite will broadcast to a plurality of the deployed devices, on a channel and/or frequency shared by many, if not all, of the devices in a deployment, information including, but not limited to: data, tasks, requests for information (e.g. status of tasks, geolocation of a device or group of devices, amount(s) of energy available for computational tasks and/or for locomotion, amount of electrical power being generated in response to the current wave conditions of a device and/or group of devices, status of computational hardware and/or networks, e.g. how many devices are fully functional and/or how many are non-functional, status of power-generating hardware and/or associated electrical and/or power circuits, e.g. how many power take-off assemblies and/or generators are fully functional and/or how many are non-functional, how many energy storage components (e.g. batteries) are fully functional and/or how many are non-functional, etc.).
In some deployments of some embodiments of the present disclosure, a satellite will broadcast to a specific deployed device, and/or subset or group of deployed devices, on a channel and/or frequency specific to the device, and/or subset or group of deployed devices, information including, but not limited to: device- or group-specific data (e.g. which range of Bitcoin nonce values to evaluate), device- or group-specific tasks (such as which types of observations to prioritize, e.g. submarines), requests for information (e.g. wave conditions at location(s) of device), etc.
In some deployments of some embodiments of the present disclosure, each device, or subset of devices, will broadcast to a satellite on a channel and/or frequency specific to the device, or subset of devices, (i.e. and not shared by other devices in a deployment) information including, but not limited to: data, task results (e.g. Bitcoin headers and/or header templates and corresponding nonce values), requests for information (e.g. new tasks, weather and/or wave forecasts for a given geolocation, results of self-diagnostics on hardware, software, memory integrity, etc., status of computational hardware and/or networks, e.g. how many devices are fully functional and/or how many are non-functional, status of power-generating hardware and/or associated electrical and/or power circuits, e.g. how many power take-off assemblies and/or generators are fully functional and/or how many are non-functional, how many energy storage components (e.g. batteries) are fully functional and/or how many are non-functional, observations (e.g. visual, audio, radar) of aircraft, observations of other floating vessels, observations of submarines, observations of marine life, observations of weather and/or wave conditions, environmental sensor readings, etc.).
By providing alternate computational resources, that draw their power directly from the environment, and by completing computational tasks currently executed in terrestrial clusters of computers, the amount of electrical power required on land can be reduced. And, thereby, the amount of electrical power generated through the consumption of fossil fuels, and the concomitant generation of greenhouse gases, can be reduced.
All potential variations in sizes, shapes, thicknesses, materials, orientations, methods, mechanisms, procedures, processes, electrical characteristics and/or requirements, and/or other embodiment-specific variations of the general inventive designs, structures, systems, and/or methods disclosed herein are included within The present disclosure.
Embodiments of the current disclosure that incorporate, contain, and/or utilize a water reservoir of substantial volume, are inherently well suited to the raising of fish, shrimp, and other animals, as well as to the growing of seaweeds, other algae, and other aqueous plants. Thus, while they extract energy from the waves about them, these embodiments can utilize at least a portion of that energy to facilitate and/or promote the growth of rich sources of nutrients which may then be harvested.
An embodiment of the present disclosure utilizes at least a portion of the energy that it generates to aerate water stored and/or cached within its reservoir so as to promote the health, growth, and/or wellbeing of the fish living therein. An embodiment of the present disclosure utilizes at least a portion of the energy that it generates to energize and/or illuminate lights, and to thereby illuminate at least a portion of the water stored and/or cached within its reservoir. An embodiment of the present disclosure utilizes at least a portion of the energy that it generates to energize and/or illuminate lights, and to thereby illuminate at least a portion of the water within its inertial water tube. An embodiment of the present disclosure utilizes at least a portion of the energy that it generates to energize and/or illuminate lights, and to thereby illuminate at least a portion of the water outside the embodiment.
Embodiments of the current disclosure that incorporate, contain, and/or utilize a water reservoir of substantial volume, can utilize at least a portion of the energy that they extract from waves to desalinate water and to store at least a portion of that desalinated water within their water reservoirs (e.g., by incremental replacement of the seawater stored within a plurality of reservoir tanks with desalinated water) or other water compartments. Such desalinated water can then be offloaded from such embodiments to ships or port installations, and the respective reservoir tanks refilled with seawater to initiate a new cycle of desalinated water production.
Embodiments of the current disclosure that incorporate, contain, and/or utilize a water reservoir of substantial volume, can utilize at least a portion of the energy that they extract from waves to remove (e.g., boil off) water from the seawater stored within their respective reservoirs thereby creating brines of high salinity, and also brines rich in minerals. Such mineral-rich brines can then be offloaded from such embodiments to ships or port installations, and desirable minerals can then be extracted from the respective brine solutions with relative efficiency.
Embodiments of the current disclosure can utilize a portion of the energy that they extract from waves to spray or pump seawater into the air, or otherwise aerosolize seawater, so as to promote cloud formation and reduce, at least to a degree, the amount of energy absorbed by the Earth from the Sun.
The current disclosure includes an embodiment in which a portion of the pressurized water within the embodiment's pressurized reservoir is discharged through a nozzle in order to generate a spray, mist, and/or aerosolization of that water.
The current disclosure includes an embodiment in which a portion of the water within the embodiment's elevated reservoir is discharged through a nozzle in order to generate a spray, mist, and/or aerosolization of that water.
The current disclosure includes an embodiment in which an electrically powered pump and/or blower is used to aerosolize seawater and project, propel, and/or spray, it into the atmosphere.
Embodiments of the current disclosure generate power (e.g., electrical, chemical, etc.) far from shore. And, there are many uses for electrical power that is generated and made available far out at sea.
Ocean charging stations for autonomous and/or remotely operated, ocean-going or airborne, “drones,” especially military drones, can consume large amounts of power, and the effective ranges of operation of those drones can be limited if the only source of energy available to those drones is from an onshore on nearshore facility. Surveying of the ocean floor and the detection of submarines far from shore can consume large amounts of power and are impractical in the absence of a source of abundant energy far from shore. Communications relays (e.g. for submarines) and radar stations floating on the deep sea can consume large amounts of power and require a source of energy from which they can obtain that power while far from shore. Ocean-floor mining operations can consume large amounts of power over long periods of time. Embodiments of the present disclosure can provide power to such mining operations.
Embodiments of the present disclosure may present tethers, mooring lines, cables, arms, sockets, berths, chutes, hubs, indentations, and/or connectors, to which another vessel may attach, and/or moor, itself. Embodiments of the current disclosure can utilize a portion of the energy that they extract from waves to charge, and/or to provide energy, e.g., transmitting that energy conductively and/or inductively via charging connections and/or pads, to manned vessels and/or aircraft, and/or to autonomous vessels and/or aircraft (i.e. “drones”), including, but not limited to, boats, ships, submarines, aircraft (e.g., helicopters), unmanned surface vessels, unmanned submersible vessels, unmanned aircraft, and/or ocean-going and airborne drones.
Such embodiments, when incorporating appropriate surfaces, enclosures, extensions, connections, and/or interfaces, may provide a suitable docking, landing, resting, and/or staging, location at which certain compatible vessels and/or vehicles can recharge, and subsequently disengage from the respective embodiments and resume their journeys and/or missions. Such embodiments, when incorporating adequate communications channels may also facilitate the exchange of data between docked vessels and/or vehicles and remote computers, networks, facilities, individuals, and/or installations.
Embodiments of the present disclosure may present connectors, protocols, APIs, and/or other devices or components or interfaces, by and/or through which energy may be transferred and/or directed to be transferred from the embodiments to another vessel. The vessels that might receive such energy include, but are not limited to:
The deployment of embodiments of the present disclosure for the purpose of charging of drones in the deep sea and/or far from shore may not utilize all of the power generated by those embodiments. Their cost of energy may therefore be relatively high. However, such deployments can be made more economical, and/or the cost of their energy can be reduced, if there is a use to which each embodiment's electrical power can be applied after the power requirements of any charging drones have been satisfied. The execution of computationally intensive tasks using computational circuits incorporated within, and powered by, each embodiment is one of the simplest, most low-capital-cost and low-maintenance ways of using electrical power.
When any connected drones are fully charged and/or a device's energy stores are full, then some embodiments of the present disclosure will consume surplus and/or supplemental generated electrical power performing other useful tasks (e.g., concentrating brine, or performing energy-intensive computations, such as Bitcoin mining and/or arbitrary or custom computational tasks for third parties), and/or creating useful products (e.g., hydrogen), in order to generate (additional) revenue and/or profits. Such a dual purpose and/or application may also facilitate an embodiment's charging of drones (e.g., through the production of hydrogen), and/or may facilitate the concealment and/or hiding of drones when the ratio of embodiment devices to drones is relatively high.
Embodiments of the present disclosure, when deployed in anchored farms of devices, or when free-floating, especially as individual devices, will primarily energize, operate, and monitor various sensors, such as, but not limited to: sonar, radar, cameras, microphones, hydrophones, antennae, gravimeters, magnetometers, and Geiger counters, in order to monitor their environments (air and water) in order to detect, monitor, characterize, identify, and/or track other vessels and/or aircraft, or to survey the ocean floor for minerals and other characteristics.
Embodiments of the present disclosure may detect, monitor, log, track, identify, and/or inspect (e.g. visually, audibly, and/or electromagnetically), other vessels passing within a sufficiently short to distance of a device such that at least some of the device's sensors are able to detect, analyze, monitor, identify, characterize, and/or inspect, such other vessels.

Embodiments of the present disclosure may present connectors, APIs, and/or other devices or components, by and/or through which data may be exchanged between the embodiment and another vessel. Such other vessels might utilize such a data connection in order to obtain cached data, messages, signals, commands, and/or instructions, preferably encrypted, transmitted to the device from a remote source and/or server, and stored within the device, and/or within a plurality of devices, any one of which may be accessed by another vessel for the purpose of obtaining command and control information.

These and other objects of the invention will best be understood with reference to the accompanying figures and the detailed description of the preferred embodiments below.
For a fuller understanding of the nature and objects of the invention, reference should be made to the preceding detailed description, taken in connection with the accompanying drawings. The following figures offer explanatory illustrations, which, like most, if not all, explanations and illustrations are potentially useful, but inherently incomplete. The following figures, and the illustrations offered therein, in no way constitute limitations, either explicit or implicit, on The present invention.
The buoyant embodiment 100 floats adjacent to an upper surface 101 of a body of water over which waves tend to pass. The embodiment incorporates a tapered inertial water tube 102-104 characterized by approximately circular cross-sections with respect to sectional planes normal to a (nominally vertical) longitudinal axis of the tube, and/or normal to an axis of inner-tube fluid flow, i.e., characterized by approximately “flow-normal cross-sectional shapes and/or areas”. An upper first portion 102 of the inertial water tube 102-104 has a frusto-conical shape (having circular flow-normal cross-sectional areas that increase in diameter with respect to increasing depths within the body of water 101 on which the embodiment floats). A second portion 103 of the inertial water tube 102-104 has a frusto-conical shape of a greater included angle. And, a bottom-most third portion 104 of the inertial water tube 102-104 is approximately cylindrical (having circular flow-normal cross-sectional areas that are approximately constant with respect to increasing depths within the body of water 101 on which the embodiment floats). Inertial water tube segment and/or portion 104 has a mouth 105 (which can also be referred to as an ingress orifice or water ingress/egress mouth) at its lower end that is open to the body of water 101 and allows water from the body of water to flow 106 in and out of the tube.
As the embodiment 100 moves up and down in response to passing waves, water within the inertial water tube 102-104 will occasionally move up and out of the upper mouth (not visible) inside the embodiment of the inertial water tube, thereby depositing water within an enclosed water reservoir 107. Water from that reservoir 107 drains through an effluent pipe 108 or channel in which is positioned a water turbine (not visible) within effluent pipe 108. As water flows from the reservoir 107 through effluent pipe 108 and back to the body of water 101, the flowing water causes the water turbine within the effluent pipe to rotate. And, rotations of the water turbine and an attached turbine shaft 109, causes to rotate the rotor (or other relevant rotating or moving element) of a generator 110 thereby generating electrical power.
As water exits an effluent pipe discharge mouth 111 (also referred to as an external effluent port) of a lower portion of effluent pipe 108B, it engages and/or is diverted by a rudder 112, which, when oriented with its broad surfaces at an angle to the effluent exiting effluent pipe discharge mouth 111, causes the embodiment 100 to rotate about its nominally vertical longitudinal axis, thereby allowing the embodiment's control system (not shown) to steer the embodiment by altering, changing, and/or adjusting the position of the rudder 112.
A portion of the electrical power generated by the generator 110 is used to energize a plurality of computing devices positioned within a computer chamber 113, enclosure, module, or compartment. One wall of computer chamber 113 is adjacent to water reservoir 107 and the water therein, thereby facilitating the absorption by the water within the water reservoir of a portion of the heat generated by the computers inside computer chamber 113.
A computer within computer chamber 113 exchanges data with a computer not directly connected to embodiment 100 via encoded electromagnetic transmissions generated and received by a phased array antenna 114 attached to a top surface of the water reservoir 107.
As the embodiment 100 moves up and down in response to passing waves, water 101 outside the embodiment moves 106 into and out of the inertial water tube 102-104, through its lower mouth 105, resulting in a surface 117 of the water within the tube 102-104 moving 118 up and down, typically in an oscillatory fashion. Occasionally, and/or periodically, especially when the downward movements of the tapered walls of the inertial water tube impinge upon an upwelling body of water 117 within the inertial water tube thereby causing an increase in the pressure of the water within the tube, the surface 117 of the water within the inertial water tube 102-104 moves high enough to allow a portion of that water to escape the upper mouth 115 of the tube, thereby ejecting water 117 against a water diverter 116 which tends to break up the ejected stream of water into a spray. The ejected water tends to encounter the curved upper wall 119 of the water reservoir 107, and a plurality 120 of chains hanging therefrom, which tend to rob the ejected water of some of its kinetic energy and direct it into the lower portion 121 of the water reservoir where it is collected into a pool 123 that is divided by a cylindrically-shaped baffle 122 through which water can flow through an aperture 124. An embodiment similar to the one illustrated in
Water 123 from the reservoir 107/122 flows through an aperture 125 into effluent pipe 108 where that water 126 flows down and through a water turbine 127 (e.g., a Kaplan or propeller turbine) causing that water turbine and a connected, and/or attached, turbine shaft 109 to rotate, thereby energizing a generator 110 and causing that generator to produce electrical power. After passing through the water turbine 127, water flowing through the effluent pipe 108 flows 128 out of an effluent pipe discharge mouth 111 positioned at a lower end 108B of the effluent pipe, thereafter passing over and around a rudder 112 whose angular orientation relative to the effluent outflow can be adjusted so as to steer the embodiment 100.
Inside the buoy 100, or buoyant portion, of the embodiment to which the inertial water tube 102-104 is attached, and/or comprising, at least in part the walls of that buoy 100, is a layer or wall 129 of buoyant material, which can, for instance, comprise a hermetically sealed hollow metal wall whose interior contains air or closed-cell plastic foam. For clarity of exposition, the thickness of the layer or wall 129 is not drawn to scale; the thickness of this layer or wall 129 must be sufficient to provide buoyancy to the embodiment sufficient to elevate reservoir 107/122 to the desired vertical level (taking into account the amount of water in water ballast 130) and will be subject to various thicknesses and configurations depending on desired performance characteristics and target wave conditions. Inside the hollow of the buoy 100 is an adjustable volume of water ballast 130. In relatively energetic wave conditions, when ejections of water from the upper mouth 115 of the inertial water tube are relatively vigorous, the amount of water ballast can be reduced, thereby lowering the waterline 131 relative to the embodiment and decreasing the draft of the embodiment, and raising the height of the water 123 in the reservoir 107/121, relative to the mean level 101 of the body of water on which the embodiment floats, and thereby increasing the head pressure associated with the water 123 in the reservoir 107/121 (with respect to that water's discharge back into the body of water 101). Furthermore, by lowering the waterline 131 of the embodiment 100, a decrease in the amount of water ballast 130 within the buoy 100 can decrease the waterplane area of the embodiment (i.e., as the waterline is lowered, the effective diameter of the waterplane area decreases) which will tend to reduce the amount of wave energy absorbed by the embodiment, which, in turn, will tend to help insulate the embodiment from an excessive influx of energy which might stress the embodiment and potentially cause it damage.
By contrast, in relatively mild wave conditions, when the level 117 of water within the inertial water tube 102-104 might not rise high enough to escape the upper mouth 115 of the inertial water tube (resulting in a cessation of electrical energy production), the amount of water ballast 130 can be increased, thereby raising the waterline 131 and increasing the draft of the embodiment and lowering the height of the water 123 in the reservoir 107/121 relative to the mean level 101 of the body of water on which the embodiment floats, and thereby decreasing the head pressure associated with the water 123 in the reservoir 107/121 (with respect to that water's discharge back into the body of water 101). By raising the waterline 131 of the embodiment 100, an increase in the amount of water ballast 130 within the buoy 100 can increase the waterplane area of the embodiment (i.e., as the waterline is raised up to and including the approximate middle of buoy 100 where the diameter of a flow-normal cross-sectional area is greatest, the effective diameter of the waterplane area increases) which will tend to cause the embodiment to absorb a greater fraction of the wave energy impinging on it.
Thus, in certain circumstances, by decreasing the volume and mass of water ballast 130 within the embodiment, a lesser amount of ambient wave energy can tend to be absorbed, but that energy will be processed more efficiently (e.g., through the availability of greater head pressure in the water 123 that flows through the water turbine 127). And, likewise, in certain circumstances, by increasing the volume and mass of water ballast 130 within the embodiment, a greater amount of ambient wave energy can tend to be absorbed thereby helping to better preserve a more nominal level of electrical power production, albeit by means of a water turbine 127 driven by water 123 possessing less head pressure.
Note that water turbine 127 will typically have a set of blades on its runner (not shown for clarity of exposition) and will typically have a converging and expanding/diverging (Venturi) sections upstream and downstream of the runner respectively (also not shown for clarity of exposition). In many figures of this disclosure, schematic representations of water turbines are simplified for clarity of exposition, and one skilled in the art will understand that established design principles applicable to water turbines will be aptly considered, including considerations related to the prevention of cavitation.
The embodiment includes a control system and/or module that controls and/or adjusts the level 130 and volume of the water ballast inside the buoy 100 through its control of a pump that connects the water within that water ballast to the water 101 outside the embodiment. In one embodiment, the level 130 and volume of the water ballast is controlled by actuating a valve that, when open, allows water to pass between the interior of the inertial water tube 118 and the water ballast chamber 130.
A portion of the electrical power generated by the embodiment is consumed by computers 132 within a computer chamber 113. Thus, electrical energy generated by the embodiment, and by extension the embodiment itself, is, at least in part, monetized through the execution of computational tasks for third parties, wherein the tasks and/or the data for those tasks is received (at least in part) via encoded radio transmissions received, e.g., by satellite, by the embodiment's phased array antenna 114. And, at least a portion of the results of the completed computational tasks are transmitted to a remote computer, server, receiver, or service, via encoded radio transmissions transmitted, e.g., to a satellite, by the embodiment's phased array antenna 114.
The embodiment illustrated in
The buoyant embodiment 200 floats adjacent to an upper surface 201 of a body of water over which waves tend to pass. The embodiment incorporates an inertial water tube 202-203 comprised of both convex (e.g., 203) and concave (e.g., 202) tubular segments. A lower mouth 204 allows water to move 205 into and out from the interior of the inertial water tube 202-203. And, an upper mouth (not visible and inside the embodiment) of the inertial water tube 202-203 allows water to be ejected up and out of the inertial water tube, and into a water reservoir 206, when the water inside the inertial water tube rises fast enough and/or far enough. A portion of the gravitational potential energy and kinetic energy of the water ejected from the upper mouth of the inertial water tube 202-203 is preserved through the capture of a portion of that water in the water reservoir 206 which is positioned above the surface 201 of the body of water to which it will return.
A portion of the water trapped in the water reservoir 206 is returned to the body of water 201 on which the embodiment 200 floats through an effluent pipe (not visible) in which is positioned a water turbine (not visible). When water flows through the discharge pipe, the water turbine therein is caused to rotate at least in part due to the head pressure of the water flowing to and through it from the water reservoir. The rotation of the water turbine by outflowing water causes an operatively connected generator 207 to be energized resulting in the generation of electrical power.
A portion of the water trapped in the water reservoir 206 may be returned to the body of water 201 on which the embodiment 200 floats through either or both of two effluent pipes 208 and 209. Because of their tangential orientation with respect to the vertical longitudinal axis of the embodiment, the discharge of water through the effluent pipe discharge mouth positioned at the lower end of effluent pipe 208 will tend to rotate the embodiment in a counter-clockwise direction (with respect to a top-down perspective). Likewise, the discharge of water through the effluent pipe discharge mouth at the lower end of effluent pipe 209 will tend to rotate the embodiment in a clockwise direction (with respect to a top-down perspective). The discharge of water through both effluent pipes 208 and 209 at approximately equal rates of flow will tend to produce torques on the embodiment that cancel each other and result in no rotation of the embodiment.
Effluent regulation motors 210 and 211 control the rate at which water from the water reservoir 206 is discharged and/or able to flow through and from effluent pipes 208 and 209, respectively, e.g. by adjusting the degree of openness, and/or the degree of obstruction, of two respective effluent valves or stoppers (not visible) positioned and/or operated adjacent to an upper end and/or mouth of effluent pipes 208 and 209. A control module and/or system (not shown) controls the behavior of the effluent regulation motors, and therethrough the angular orientation (i.e., the direction of travel) of the embodiment, as well as other aspects of the embodiment's behavior and operation.
A buoy, chamber, enclosure, canister, and/or portion 212 of the embodiment is hollow and contains water ballast, the volume of which may be adjusted, that is used to raise and lower the embodiment's waterline, and respectively to lower and raise the head pressure of the water in the water reservoir 206. A buoyant collar 213 provides the embodiment with a measure of permanent buoyancy which, following a reduction of water ballast within chamber 212, will tend to lift the embodiment to a height that places its buoy 212 in a more elevated position relative to the surface 201 of the water on which the embodiment floats.
The embodiment's control module (not shown) controls and/or adjusts the volume of water ballast within the buoy 212 through its control of a pump and pump conduit (not shown) that connects the water ballast within the interior of the buoy 212 to the water 201 outside the embodiment.
Attached to an upper exterior surface of the water reservoir 206 is a phased array antenna 214 comprised, at least in part, of a plurality of individual dipole antennas.
Water trapped in water reservoir 206 flows 215 back into the body of water 201 from which it was initially captured through an effluent pipe discharge mouth 216 of effluent pipe 217, and, due to the lateral flow vector of the discharged water, will tend to generate and/or produce thrust that propels the embodiment in a direction opposite to the direction 215 of the effluent discharge.
The downward flow of water through effluent pipe 217, under the influence of the head pressure imparted to the flow by the height of the water reservoir 206 above the surface 201 of the body of water into which it flows, engages, and/or energizes, a water turbine (not visible) positioned within the effluent pipe thereby causing it to rotate. And, the rotation of the water turbine within effluent pipe 217 causes an operatively connected generator 207 to generate electrical power. Baffles can be provided to limit sloshing in reservoir 206.
The discharge of a water from the water reservoir 206 through effluent pipes 208 (and 209 in
Effluent regulation motors 210 and 211 raise or lower respective rods 218 and 219, which in turn raise or lower respective stoppers (not visible) of respective effluent valves (not visible), that open or close respective apertures within the water reservoir 206. When an effluent pipe's respective effluent valve is opened, e.g., through a raising of its respective stopper, then water flows from the water reservoir 206, under, with, and/or in response to, the head pressure associated therewith, out of the effluent pipe discharge mouth of the respective effluent pipe. When water flows from the water reservoir through effluent pipe 208 and discharges 220 into the body of water 201 then a torque is applied to the embodiment, with respect to a vertical longitudinal axis of the embodiment, causing the embodiment to turn to the right (with respect to the perspective of
In the embodiment configuration illustrated in
As the embodiment 200 moves up and down in response to passing waves, water within the inertial water tube 203 will tend to oscillate, and be excited by the constricting/tapered walls of said water tube, and will tend to occasionally rise fast enough and far enough such that a portion of the water in the inertial water tube is ejected from the upper mouth 223 of the inertial water tube and into the reservoir (206 in
Note how discharges 220 and 221 of pressurized water from effluent pipes 208 and 209, respectively, will generate a torque about a longitudinal axis (e.g., passing through and normal to the upper mouth 223) of the embodiment thereby causing the embodiment to turn about that axis, and allowing the embodiment's control system (not shown) to steer the embodiment with respect to the more substantial forward thrust generated by the discharge 215 of water through effluent pipe 217.
As embodiment 200 moves up and down in response to waves traveling across the surface 201 of the body of water on which the embodiment floats, the water within the inertial water tube 202-203, and the surface 224 of that water, tend to move up and down, the former being excited in oscillation by the rise and fall of the embodiment. Occasionally, the surface 224 of the water within the inertial water tube 202-203 rises fast enough and far enough that a portion of that water is ejected and/or projected up and out of the upper mouth 223 of the inertial water tube. That ejected water may then collide with water diverter 225 whereupon it is, at least in part, dispersed, thereafter tending to fall into the pool 226 of water (or creating such a pool of water) within the water reservoir 206. The upper end 222 of the inertial water tube extends into the reservoir through an approximately cylindrical wall 236 at the center of the water reservoir 206.
Inertial water tube 202, 203, 227, 222 is comprised of segments that alternate between convex and concave. Segments 203 and 227 are convex (i.e., they differ from frustoconical in that they tend to bulge outward near the centers of the segments). Whereas segments 202 and 222 are concave (i.e., they differ from frustoconical in that they tend to bulge inward near the centers of the segments).
Note that this figure is not necessarily to scale, and the scope of the present disclosure includes inertial water tubes of any shape, design, size, and/or configuration. In one embodiment of the present disclosure, the ratio of the total height of inertial water tube to the diameter of a flow-normal cross-sectional area of buoy 212 is significantly greater than the one depicted or implied in
Some of the water 226 within the water reservoir 206 flows down through effluent pipe 217 thereby engaging, and causing to rotate, water turbine 228, positioned therein. The water turbine 228, in turn, imparts rotational kinetic energy to turbine shaft 229, which energizes operatively connected generator 207 causing it to produce electrical power. After passing and/or flowing through, and imparting rotational kinetic energy to, water turbine 228, the water in effluent pipe 217 flows 215 out of effluent pipe discharge mouth 216, thereby generating forward thrust that tends to propel the embodiment to the right (with respect to the illustration in
When, as illustrated in
A similar stopper is actuated by effluent regulation motor 210 (in
Buoy chamber 212 is substantially hollow and nominally contains a water ballast 231 of adjustable volume and mass (e.g., wherein the volume of water ballast is adjusted by a pump, not shown, controlled by the embodiment's control system (not shown), that pumps water from the water ballast into the body of water 201 on which the embodiment floats in order to reduce the volume and mass of the ballast, thereby tending to cause the embodiment's draft to decrease, or, conversely, pumps water from the body of water 201 on which the embodiment floats into the buoy chamber 212 in order to increase the volume and mass of the water ballast 231, thereby tending to cause the embodiment's draft to increase. A layer 232 of rocks, gravel, and/or other aggregate material, helps to reduce side-to-side flows of water within the water ballast, and to thereby stabilize the orientation of the embodiment with respect to wave motion.
Within buoy chamber 212, and attached to a wall of the inertial water tube 227, is a computer chamber 233, enclosure, container, module, and/or vessel, which contains, at least in part, a plurality of computing devices which consume at least a portion of the electrical power generated by the embodiment's generator. One wall 234 of the computer chamber is connected to, or shared by, the inertial water tube thereby facilitating the passive and/or conductive cooling of the computing devices within the enclosure 233.
Attached to an inner upper surface inside the buoy chamber 212 is a layer 235 of buoyant material which provides a degree of permanent buoyancy, and a measure of safety that the embodiment will not sink following an unanticipated accident, or unanticipated damage (e.g., from a collision with a ship or other water vessel).
Effluent pipes 208 and 209 are connected to water reservoir 206, and the water 226 therein, by apertures, e.g., 237, in a bottom wall of the water reservoir. Stoppers 238 and 230 control the flow of water, and/or the rate at which water flows, through each respective effluent pipe 208 and 209. When a stopper, e.g., 238, is fully lowered, thereby fully obstructing its respective aperture, then water 226 from the water reservoir is unable to flow into and/or through the respective effluent pipe, e.g., 208. Conversely, when a stopper, e.g., 230, is raised, and does not fully obstruct its respective aperture, e.g., 237, then water 226 from the water reservoir is able to flow into and through the respective effluent pipe, e.g., 209, thereby generating a tangential thrust that tends to turn the embodiment and permit the embodiment's control system (not shown) to steer the embodiment in a desirable direction, along a desirable course, and/or to a desirable location. Stoppers 238 and 230 are raised and lowered by their respective lifting rods 218 and 219, which are raised and lowered by their respective effluent regulation motors 210 and 211.
The embodiment illustrated in
The head pressure of the water that flows through pipe 239, and originates in and/or from the water reservoir 206, forces that water to pass through an effluent filter 240, mat, block, aggregation, collection of membranes, and/or puck comprised of material with a tendency to adsorb, absorb, or otherwise collect certain elements, minerals, and/or compounds from the seawater flowing through it (for instance, the effluent filter, mat, block, aggregation, collection of membranes and/or puck may be composed and/or comprised, at least in part, of adsorbing fibers, yarns, and/or solids contained within a porous fabric bag). When the gravitational potential energy and/or head pressure of the water within the water reservoir 206, is relatively high, then the efficiency with which effluent filter 240 adsorbs target and/or desirable chemical may tend to be increased. And, following its passage through the mineral-adsorbent effluent filter 240, water draining and/or flowing from the water reservoir 206 through effluent pipe 239 returns 241 to the body of water 201 outside the embodiment, through effluent pipe discharge mouth 242, providing (additional) thrust to propel the embodiment in a forward direction (i.e., toward the right with respect to the embodiment configuration illustrated in
Effluent filters 240, such as the one illustrated in
In one embodiment of the present disclosure, the adsorbing material of the embodiment's effluent filter 240 preferentially adsorbs lithium and/or lithium compounds. In one embodiment of the present disclosure, the adsorbing material of the embodiment's effluent filter 240 preferentially adsorbs rubidium and/or rubidium compounds. In one embodiment of the present disclosure, the adsorbing material of the embodiment's effluent filter 240 preferentially adsorbs uranium and/or uranium compounds.
An embodiment of the present disclosure similar to the one illustrated in
The embodiment illustrated in
The buoyant embodiment 300 floats adjacent to an upper surface 301 of a body of water over which waves tend to pass. The embodiment incorporates an inertial water tube 302 comprised of an approximately frusto-conical top portion (not visible) and an approximately cylindrical bottom portion 302. Surrounding the frusto-conical top portion of the inertial water tube is an annular ring 303 comprised of buoyant material that provides the embodiment with at least a degree of permanent buoyancy and reduces the average density of the embodiment 300. A hollow chamber 304, enclosure, buoy, and/or portion of the embodiment provides structural support for four water reservoirs 305-308. And, each of the four water reservoirs 305-308 supports, and/or is attached to, a generator 309-312, respectively, that is operatively connected to a reservoir-specific water turbine (not visible).
As the embodiment 300 moves up and down in response to waves traveling across the surface 301 of the body of water on which it floats, water within the embodiment's inertial water tube 302 tends to oscillate in a direction approximately parallel to a longitudinal axis of the inertial water tube, occasionally ejecting water from tubes (not visible) and upper mouths and/or apertures (not visible) incorporated within and/or at an upper end of the inertial water tube 302. Water ejected from the top of the inertial water tube 302 enters one of the four water reservoirs 305-308 at an approximately tangential orientation to each respective water reservoir's radially-symmetrical interior, thereby tending to induce in the water therein a swirling motion.
Water within each water reservoir 309-312 flows back to the body of water 301 through a respective effluent pipe e.g., 313 and 314, each effluent pipe of which is oriented so as to release and/or discharge its effluent in an approximately lateral direction and to thereby generate a propulsive thrust that tends to move the embodiment in a lateral direction (e.g., in a direction parallel to the surface 301 of the body of water on which the embodiment floats). Two effluent pipes at a “front side” of the embodiment (the side adjacent to reservoirs 305 and 306) are angled so as to release water in a direction that is, to a degree, tangential to the embodiment, and tends to produce both forward (to the left of the illustrated embodiment) and tangential thrust, the tangential thrust tending to cause the embodiment to turn relative to a vertical longitudinal axis of the embodiment.
The energy extracted by the water turbine within the effluent pipe operatively connected to each water reservoir 305-308 arises from both the gravitational potential energy (i.e., head pressure potential energy) of the water, and the rotational (or angular) kinetic energy of the water's swirling.
Attached to an upper surface of the exterior wall of the inertial water tube 302 is a computer chamber 315 compartment, enclosure, and/or module that contains a plurality of computing devices, components, and/or other electronic components, modules, systems, and/or equipment. The computing devices within the computer chamber 315 are energized with electrical power generated at least in part by the generators 309-312. And, the computing devices within the computer chamber 315 receive instructions, programs, and/or data from a remote transmitter, e.g., from a satellite, by means of encoded electromagnetic signals transmitted to, and captured by, an antenna 316. Completed computational results and data are transmitted to a remote transmitter, e.g., to a satellite, by means of encoded electromagnetic signals transmitted from antenna 316. For clarity, as in all embodiments of this disclosure, such a computer chamber can be located anywhere in and/or on the embodiment, and in some embodiments it is located at least partially below a mean waterline of the embodiment and has an outer wall, and/or an operatively connected heat exchanger, that is in contact with the water 301 on which the embodiment floats so as to allow the ambient external water to cool the computer chamber.
Water flows 317 into, and out from, a lower mouth 318 at a bottom end of inertial water tube 302.
The hollow chamber 304, enclosure, and/or portion of the embodiment is able to contain a variable and/or adjustable volume and/or mass of water ballast, e.g., comprised of water. The volume of that water ballast may be adjusted by the embodiment's control system (not shown) through its activation and/or control of one or more pumps (not shown) which are able to remove water from the water ballast, thereby reducing the embodiment's draft, and to add water to the water ballast, thereby increasing the embodiment's draft.
In response to the discharge of water from the water reservoirs 305-308, the embodiment 300 will tend to be propelled to the left (with respect to the embodiment orientation illustrated in
A discharge of water from water reservoir 306 through and/or from effluent pipe 319 will tend to generate a first tangential thrust that, at least to a degree, will tend to cause the embodiment 300 to rotate about a vertical longitudinal axis in a counter-clockwise direction (as viewed from above the embodiment). Whereas a discharge of water from water reservoir 305 through and/or from effluent pipe 313 will tend to generate a second tangential thrust that, at least to a degree, will tend to cause the embodiment 300 to rotate about a vertical longitudinal axis in a clockwise direction (as viewed from above the embodiment).
By adjusting the relative rates at which water flows from the water reservoirs 306 and 305 and out of the respective effluent pipes 319 and 313, such that those rates of relative outflow and/or discharge are unequal and/or imbalanced, a differential torque can be applied to the embodiment, causing the embodiment to turn about a vertical axis in the direction dictated by the effluent pipe with the greater rate of flow. By contrast, when the rates of outflow and/or discharge out of effluent pipes 319 and 313 are approximately equal, then the embodiment will tend to move forward in a lateral direction across the surface 301 of the body of water on which the embodiment floats (e.g., in a direction normal to, and out of the page, and toward the reader, with respect to the orientation of the embodiment illustrated in
A control system and/or module (not shown) controls the relative torques, and or resistance, imparted by generators 310 and 309 to their respective water turbines (not visible, inside respective effluent pipes 319 and 313) in order to control the relative rates of outflow and/or discharge of water from effluent pipes 319 and 313, respectively. By increasing the torque and/or resistance imparted by a generator to its respective operatively connected shaft and water turbine, the embodiment's control system can reduce the rate at which water flows out of that generator's respective effluent pipe. Conversely, by reducing the torque and/or resistance imparted by a generator to its respective operatively connected shaft and water turbine, the embodiment's control system can increase the rate at which water flows out of that generator's respective effluent pipe. Thus, by controlling and/or adjusting the torque and/or resistance imparted by a generator to its respective operatively connected shaft and water turbine, the embodiment's control system can control and/or adjust the rate and direction at which the embodiment will turn, thereby allowing the control system to steer the embodiment with respect to the thrust, and/or components of thrust, that tend to propel the embodiment forward. However, in some embodiments, increasing and reducing the torque imparted by a generator is not used to adjust the rate of flow out of a generator's respective effluent pipe, but instead, a valve is used to adjust the rate of flow. In either case, the turbine or valve is a species of flow governor that limits the flow rate of water from the respective reservoir so as to maintain a relatively constant flow out of the embodiment despite the fact that injections of water to the respective reservoir is sporadic and stochastic.
Water that flows from water reservoirs 305-308 and is discharged into the body of water 301 through effluent pipes 313, 319, 320, and 314, respectively, tends to generate and/or produce, at least to a degree, thrust that tends to the propel the embodiment forward (i.e., normal to, and into, the page with respect to the embodiment orientation illustrated in
Embodiment 300 floats at the surface of a body of water and tends to move up and down in response to passing waves. As the embodiment rises and falls, water within an inertial water tube 302 (in
Computer chamber 315 is attached to an upper end of inertial water tube 321, and antenna 316 is attached to an upper surface of the computer chamber 315.
As the embodiment 300 moves up and down in response to passing waves, water inside inertial water tube 302 tends to move up and down. Occasionally, water rising within tube 302 reaches the upper interior wall 326 of the tube and is thereby blocked. Upon reaching, or almost reaching, the top inertial tube wall 326, water rising within tube 302 tends to move laterally through apertures and/or ejection pipes 322-325, after which portions of such diverted flows of water may flow into corresponding and/or respective water reservoirs 305-308. When water reaches the upper end 326 of inertial water tube 302 with sufficient energy, then those portions of the inertial water tube's water that flow through ejection pipes 322-325 may still possess kinetic energy upon their ejection from those ejection pipes. Portions of such residual kinetic energy may be imparted to the water within the respective water reservoirs as rotational kinetic energy and/or angular momentum.
Water flowing from water reservoirs 305 and 306 (in
Water flowing from water reservoirs 307 and 308 (in
As the embodiment 300 moves up and down in response to passing waves, water inside inertial water tube 302/321 tends to move up and down. When the level 327 of the water inside the inertial water tube 302/321 rises high enough to reach the ejection pipes, e.g., 325, water will flow from the vertical inertial water tube 302/321 and through the ejection pipes, e.g., 325, and flow into a respective water reservoir, e.g., 308, from a point and/or aperture, e.g., 328, that is adjacent to the approximately circular interior wall of the respective reservoir, e.g., 308. The approximately tangential discharge of water from the ejection pipes, e.g., 325, into the respective water reservoirs, e.g., 308, tends to induce a swirling motion or vortex within the water trapped within each respective water reservoir. Thus, the sectional profile of the water within each reservoir can tend to be similar to that of a vortex wherein the level 329 of the water near the center of the vortex tends to the lower than the level 330 of the water at its periphery.
Adjacent to, and attached to, an upper exterior surface of each water reservoir, e.g., 306, is a generator, e.g., 310. Depending from, and operatively connected to, each generator, e.g., 310, is a turbine shaft, e.g., 331. A lower end of each shaft, e.g., 331, is connected to a water turbine, e.g., 332. Water, e.g., 330, from each water reservoir drains and/or flows into an effluent pipe, e.g., 319, wherein the rotational kinetic energy and head pressure of the flowing water imparts rotational kinetic energy to a respective water turbine, e.g., 332, therein. Water that flows through and past each water turbine is discharged into the body of water 301 through an effluent pipe discharge mouth at a lower end of each respective effluent pipe, e.g., 319, thereby generating lateral thrust that tends to push against the embodiment in a direction normal to the embodiment's vertical longitudinal axis and/or approximately parallel to the resting surface 301 of the body of water on which the embodiment floats.
Within the hollow interior of hollow chamber 304 is water ballast 333. A pump (not shown) allows the embodiment's control system (not shown) to alter, adjust, and/or control, the level, volume, and/or mass, of the water ballast within the hollow chamber 304, thereby allowing the embodiment's control system to adjust, and/or control, the mass of the embodiment, its displacement, its draft, and its waterline 334. When the mass of the ballast 333 is reduced, the embodiment tends to rise in the water concomitantly lowering its waterline and decreasing its draft. Because the bottom portion of hollow chamber 304 is tapered, and because the cross-sectional area of the hollow chamber 304 decreases with increasing vertical distance from the top of the embodiment, e.g., the top of antenna 316, a lowering of the embodiment's waterline 334 tends to reduce the embodiment's waterplane area. This in turn tends to reduce the fraction of the available wave energy that is imparted to the embodiment, while also increasing the energy threshold that must be reached in order for water rising within inertial water tube 302/321 to reach and escape the ejection pipes. Thus, reducing the water ballast 333 tends to insulate, at least to a degree, the embodiment from excessive wave energy as might be encountered during storms.
On the other hand, when wave conditions are of and/or at suboptimal energy levels, e.g., during relatively calm conditions, then the embodiment's control system (not shown) can increase the level 333 of the water ballast, thereby raising the waterline, increasing the embodiment's draft, and increasing the embodiment's waterplane area, and thereby increasing the fraction of the available wave energy that is imparted to the embodiment. The raising of the embodiment's waterline also can tend to reduce the energy threshold that must be reached in order for water rising within inertial water tube 302/321 to reach and escape the ejection pipes. Thus, in an energy-poor wave climate, raising the waterline will tend to allow a greater volume of the less energetic water oscillating within the tube 302/321 to be collected and discharged through the embodiment's water turbines. Increasing the water ballast 333 tends to compensate, at least to a degree, for the reduction in energy generation that an embodiment might otherwise experience as a consequence of reduced wave energies.
It should be noted that, as in other embodiments of this disclosure, the shown figure (and in particularly the vertical length of the cylindrical tube segment 302/321) is not necessarily to scale. In particular, the vertical length of the inertial water tube 302/321 (measured from bottom 318 to top 315) may be 2, 3, 4, 5, or more, times the maximum horizontal diameter of the hollow chamber 304. In an embodiment of the present disclosure, the vertical length of the inertial water tube 302/321 can be 100-200 meters or more, while the horizontal diameter of the hollow chamber 304 is 40-50 meters. In another embodiment of the present disclosure, the vertical length of the inertial water tube 302/321 can be 25 meters, while the horizontal diameter of the hollow chamber 304 can be 8 meters.
In response to wave-induced motion of the embodiment, water oscillates approximately vertically and/or longitudinally within the central vertical inertial water tube 321 of the embodiment 300. Occasionally, water rises within inertial water tube 321 with enough vigor that some of that water enters, and is subsequently discharged from, ejection pipes 322-325. Water discharged from ejection pipes 322-325 is ejected and/or discharged 335-338 into water reservoirs 305-308 in a direction approximately tangential to vertical longitudinal axes of approximate radial symmetry of the respective reservoirs 305-308. Because of their approximately circular horizontal cross-sections, especially at the vertical level at which water is discharged into them by the ejection pipes 322-325, water discharged 335-338 into water reservoirs 305-308 tends to induce swirling motions, e.g., 339-342, in the water contained within the reservoirs.
In order to reach, and then be discharged from, ejection pipes, water within an embodiment's inertial water tube 321 must achieve enough gravitational potential energy to rise as high as the embodiment's ejection pipes. The induction and/or creation of swirling in the waters stored within an embodiment's water reservoir(s) permits not only the capture of a portion of the gravitational potential energy of the water ejected from an embodiment's inertial water tube, it also permits the capture of a portion of any kinetic energy remaining within the discharged water (i.e., the amount of the kinetic energy, if any, that remains within the rising and/or discharged water after the requisite amount of kinetic energy in the rising water has been converted into the gravitational potential energy required by the water to reach the ejection pipes).
The water captured within the water reservoirs possesses head pressure potential energy (i.e., gravitational potential energy), and, because of the induced swirling motion of that water, the water also possesses rotational kinetic energy (i.e., angular momentum). By capturing and extracting portions of both of these types of energy, the efficiency of an embodiment of the present disclosure is increased.
In the embodiment configuration illustrated in
An upper part or portion 344 of the partition dividing tube 302 into two adjacent channels 345 and 346 is angled as its centermost longitudinal angle maintains a constant angular orientation with respect to the vertical longitudinal axis of the upper tapered portion of tube 302. A lower part or portion 343 of the partition dividing tube 302 into two adjacent channels 345 and 346 is approximately parallel to the vertical longitudinal axis of the cylindrical lower portion of tube 302.
The lower portion 343 of the partition wall is parallel to the central longitudinal axis of the inertial water tube, but is not positioned at the center of the inertial water tube, i.e., the partition wall is offset 347 from the longitudinal axis and/or from the lateral center of the inertial water tube 302. Because the partition wall 343 does not pass through the center of the inertial water tube 302, and is instead offset from such a central position, the flow-normal cross-sectional area of inertial water tube channel 345 is less than the flow-normal cross-sectional area of inertial water tube channel 346. Therefore, the average volume and/or mass of the water within inertial water tube channel 345 will tend to be less than the average volume and/or mass of the water within inertial water tube channel 346, and each channel will likely be most responsive to different wave heights, wave periods, wave states, and/or wave conditions.
Water flowing and/or oscillating within inertial water tube channel 345 occasionally flows into and out of ejection pipes 322 and 323, thereby flowing into respective water reservoirs 305 and 306. Water flowing and/or oscillating within inertial water tube channel 346 occasionally flows into and out of ejection pipes 324 and 325, thereby flowing into respective water reservoirs 307 and 308.
Because inertial water tube channels 345 and 346 have different relative cross-sectional areas, different included angles, and, in light of their approximately equal lengths, different volumes, each of the two inertial water tube channels will tend to oscillate most vigorously at different resonant frequencies, and will therefore tend to supplement their respective reservoirs at differing rates with respect to the same wave climate. However, and of greater benefit, will be their tendency to extend the range of wave climates over which at least one of the embodiment's two inertial water tube channels is supplementing its respective reservoirs at a relatively high rate.
In the embodiment configuration and/or operational state illustrated in
Any water that rises to the top of inertial water tube 321 within inertial water tube channel 345 is forced by wall 344 to exit through one of the ejection pipes 322 or 323. Likewise, any water that rises to the top of inertial water tube 321 within inertial water tube channel 346 is forced by wall 344 to exit through one of the ejection pipes 324 or 325. And, because of their tendency to be characterized by different resonant frequencies, the water within each inertial water tube channel 345 and 346 will tend to exhibit a maximum rate of flow into its respective reservoirs in response to different wave climates.
The buoyant embodiment 400 floats adjacent to an upper surface 401 of a body of water over which waves tend to pass. The embodiment incorporates four inertial water tubes each of which is comprised of a lower cylindrical portion, e.g., 402-404, a conical middle portion, e.g., 405-407, and an upper curved cylindrical portion, e.g., 408-410. The conical portions of the four inertial water tubes, e.g., 405-407, are attached to a central and/or centermost approximately frusto-conical hollow chamber 411, enclosure, buoy, and/or portion, that buoyantly holds the embodiment at the surface 401 of the body of water, and/or imbues the embodiment with an average density sufficiently less than that of that of water so that the embodiment floats adjacent to the surface 401 of a body of water.
As the embodiment rises and falls in response to waves traveling across the surface 401 of the body of water on which the embodiment floats, water enters and leaves, e.g., 412-414, the inertial water tubes, e.g., 402-407, through the respective lower mouths, e.g., 415, at the base of each inertial water tube, and the water within each inertial water tube tends to move up and down, and/or oscillate, in a direction approximately parallel to the longitudinal axis of the respective inertial water tube. Occasionally, water rises within one or more of the embodiment's inertial water tubes with sufficient speed, energy, momentum, and/or force, to cause a portion of that water to enter, and pass through, the ejection pipes, e.g., 408-410, at the upper end of each inertial water tube. Each inertial water tube's respective ejection pipe enters a central, shared, and/or common, water reservoir 416 through a space, e.g., 417-418, in a side wall of the water reservoir 416. Water is discharged into the water reservoir 416 from each ejection pipe in a direction that is approximately tangential to the flow-normal, and/or horizontal, cross-section of the water reservoir. Because of its tangential discharge and/or ejection into the water reservoir, any residual kinetic energy, speed, and/or momentum, in the water discharged from an ejection pipe will induce, and/or magnify, a swirling motion in the water within the water reservoir 416.
Water within the water reservoir flows and/or drains back to the body of water 401 on which the embodiment floats through an effluent pipe within which is a water turbine that is operatively connected to a generator 419. The generator 419 is attached to an upper exterior surface of the water reservoir 416. At least a portion of the electrical power generated by generator 419, and/or by the embodiment, is used to power a plurality of computing devices, circuits, modules, and/or systems, contained within a computer chamber 420, enclosure, box, container, housing, and/or locker. Some of the computing devices within computer chamber 420 perform and/or execute computational tasks specified by code, programs, instructions, and/or data transmitted by, and/or originating from, a remote transmitter (e.g., a satellite) and received as encoded electromagnetic signals by a phased array antenna 421 attached to an upper exterior surface of the water reservoir 416. Some of the computational results produced by the computing devices within computer chamber 420 are transmitted to a remote receiver (e.g., a satellite) by the phased array antenna 421.
The computer chamber is in thermal contact with a portion of the water reservoir's 416 wall thereby allowing a portion of the heat generated by the computing devices within the computer chamber 420 to pass into the water within the water reservoir 416, and thereby facilitating the passive and/or conductive cooling of those computing devices.
Some of the electrical power generated by generator 419, and/or by the embodiment, is used to energize one or both of a pair of ducted fans, e.g., 422, which are used to propel and steer the embodiment across the surface 401 of the body of water on which the embodiment floats, and/or to maintain the embodiment's geospatial position at the surface 401 of that body of water. In some embodiments, the geospatial position of the device is monitored and/or controlled using GPS signals.
Ducted fan 422 is energized, at least in part, by electrical power generated by the embodiment 400, and/or the embodiment's generator 419, and it blows 423 a forceful stream of air, generating thrust, thereby tending to propel the embodiment forward (i.e., to the left with respect to the embodiment orientation illustrated in
At the bottom end of each of the embodiment's four inertial water tubes, e.g., 402-404, is a lower mouth, e.g., 415, 424 and 425, into and out of which tends to flow, e.g., 412-414, water when the embodiment rises and falls in response to passing waves.
Four inertial water tubes, e.g., 406, 407, and 427, each of which incorporates a lower cylindrical portion 403, 404, 426, and 402 (in
A pair of ducted fans 422 and 431 provide propulsive thrust to the embodiment. And, by varying the amount of thrust generated by each fan, the embodiment is able to turn and steer a course across the surface 401 of the body of water, and/or to maintain a particular desired geospatial location at the surface 401 of that water (e.g., in conjunction with mooring so as to reduce the requisite strength, and/or to extend the lifetime, of that mooring). The ducted fans are energized, at least in part, with electrical energy generated by generator 419.
A pair of ducted fans 422 and 431 generate propulsive flows 423 and 432, respectively, that provide propulsive thrust to the embodiment. And, by varying the amount of thrust generated by each fan, relative to the amount generated by the other fan, the embodiment is able to turn and steer a course. A control module and/or system (not shown) controls the thrust generated by each fan, and tracks the geospatial position of the embodiment, and thereby tends to be able to move the embodiment, and/or to hold the position of the embodiment, as programmed, instructed, and/or desired (with respect to other factors, such as wave climate, winds, antenna gain, e.g., with respect to a particular remote antenna, etc.).
The embodiment incorporates four inertial water tubes 402-404 and 426, attached to a central hollow chamber 411, enclosure, buoy, and/or portion. Water within the four inertial water tubes tends to oscillate vertically, occasionally reaching and discharging water from tube-specific upper mouths, into a water reservoir through four respective ejection pipes 408-410 and 428 (note that the bottom-up illustration in
As embodiment 400 moves up and down in response to waves across the surface 401 of the body of water on which the embodiment floats, water, e.g., 436 and 437, within the embodiment's four inertial water tubes 402, 404, 426 and 403 (in
Water within the water reservoir 416 flows and/or drains back into the body of water 401 on which the embodiment floats through an effluent pipe 434 in which is positioned a water turbine 435. The combination of the swirling motion and head pressure of the water 440 flowing into effluent pipe 434 from water reservoir 416 tends to impart rotational kinetic energy and/or a torque to the water turbine 435 and to the turbine shaft 443 connected and/or attached to it. The turbine shaft 443 communicates at least a portion of the torque and/or rotational kinetic energy, produced by the water turbine 435 in response to water flowing through effluent pipe 434, to the generator 419 nominally resulting in the generation of electrical power. Water flows 445 out of, and/or is discharged by, the embodiment through an effluent pipe discharge mouth 446 at a lower end of effluent pipe 434.
The ejection pipes, e.g., 408 and 428, enter the water reservoir through portals, apertures, spaces, and/or gaps, e.g., 444, in upper portions of the walls of the reservoir 416, and if the rate at the embodiment's ejection pipes discharge water into the water reservoir exceeds, for too long a time, the rate at which water flows out of the water reservoir through effluent pipe 434, then water may leak out of the water reservoir through those apertures, e.g., 444.
A portion of the electrical power generated by generator 419 is used to energize a portion of a plurality of the computing devices 447 positioned, mounted, and/or housed, within a computer chamber 420. And a portion of the heat generated by those computing devices 447 tends to be transmitted to the water within the water reservoir 416 through a water reservoir wall 448 shared by, and/or in contact with, a wall of the computer chamber 420.
An adjustable amount, volume, and/or mass of water ballast 449 is held within the hollow chamber 411, enclosure, buoy, and/or portion, and adds to the mass of the embodiment 400 thereby affecting the inertia of the embodiment as well as the height of the embodiment's waterline 450. A pump (not shown) is controlled by the embodiment's control system (not shown), thereby enabling the control system to pump water 401 from outside the embodiment into the hollow chamber 411, thereby increasing the volume and/or mass of the embodiment's water ballast 449 and tending to raise the embodiment's waterline 450 and increase the embodiment's waterline draft, and to pump water out of the embodiment's water ballast 449, thereby decreasing the volume and/or mass of the embodiment's water ballast and tending to lower the embodiment's waterline 450 and reduce the embodiment's waterline draft.
In heavy seas, when wave energies are greater than normal, the embodiment's control system can reduce the mass of the water ballast 449 thereby lowering the embodiment's waterline 450 and decreasing the embodiment's draft, and, since the hollow chamber 411 and/or buoy is conical and its cross-sectional area, and therefore its waterplane area, decreases as the waterline is lowered, the lowering of the embodiment's waterline 450 tends to reduce the embodiment's sensitivity to the waves, thereby tending to reduce its energy absorption efficiency, which may tend to protect the embodiment from damage that might result from excessively vigorous energy absorption.
In periods of relative calm, the embodiment's control system can increase the mass of the water ballast 449, thereby raising the embodiment's waterline 450, and thereby tending to increase the embodiment's waterplane area, to increase the embodiment's sensitivity to the ambient waves, and to increase its energy absorption efficiency, which may permit the embodiment to maintain a near nominal, and/or an acceptable, rate of energy production during weak wave states.
A compartment 451 within a lower portion of the hollow chamber 411 and/or buoy provides the embodiment with a degree of permanent buoyancy.
Water moves 412, 414, 430, and 413 (in
Water that rises with sufficient force, momentum, speed, and/or kinetic energy to reach an ejection pipe 408, 409, 410, or 428, will flow out 438, 452, 453, or 439, respectively, through the ejection pipe's respective upper mouth, and will tend to enter the water reservoir 416 near the periphery of the water reservoir and with a tangential orientation, thereby tending to induce a swirling motion in the water within the water reservoir. Water within the water reservoir 416 flows down through effluent pipe 434 therein tending to engage and energize water turbine 435 and to induce, produce, and/or create a torque and/or rotational kinetic energy therein. The turning of water turbine 435 causes a rotation in the attached turbine shaft 443 which is operatively connected to a generator (419 in
Inertial water tube 406/403, with lower mouth 424, is the shortest of the embodiment's four inertial water tubes. And, inertial water tube 405/402, with lower mouth 415, is the longest. With respect to the embodiment illustrated in
The scope of the present disclosure includes embodiments with any number of inertial water tubes, any inertial water tube shape(s), any inertial water tube length(s), any inertial water tube volume(s), inertial water tubes that taper with any included angle(s), and inertial water tubes with complex shapes (e.g., tubes not simply comprised of cylindrical and frusto-conical segments). The scope of the present disclosure includes embodiments with inertial water tubes whose lengths differ as a result of differences in the lengths of the cylindrical portions of those inertial water tubes (as in the embodiment of
The buoyant embodiment 500 floats adjacent to an upper surface 501 of a body of water over which waves tend to pass. The embodiment incorporates a buoyant platform or buoy 502 which causes the embodiment to float upon the water 501. Attached to, and passing through, the buoy 502 is a nominally vertical, approximately cylindrical tube 503 which incorporates an inertial water tube (not visible) and a hollow chamber within which a water ballast of variable volume is located. A plurality of struts 504 strengthen the attachment of the cylindrical tube 503 to the buoy 502, reducing the likelihood that the changing buoyant forces applied to the buoy 502, in conjunction with the drag forces inhibiting lateral motions of the lower portion 503B of the cylindrical tube, will result in a weakening of the attachment and/or alignment of the cylindrical tube 503 to the buoy 502.
As the embodiment 500 moves up and down in response to passing waves, water within the embodiment's inertial water tube will tend to move up and down as well. In response to wave motion at and/or against the embodiment, water will tend to enter and leave 505 the inertial water tube's lower mouth 506. Occasionally, water will rise within the inertial water tube with sufficient energy, speed, and/or to a sufficient height, that a portion of that water will exit, and/or be ejected from, the inertial water tube through an upper mouth (not visible) at its upper end, thereafter tending to enter a water reservoir 507.
If water rises within the inertial water tube so quickly, and/or with such force, that the upper mouths of the tube are unable to accommodate the requisite level of flow, then that water may continue rising within the inertial water tube. If water rises in the inertial water tube with sufficient energy or force, then a pressure activated pressure-relief valve (not visible) opens and thereby allows a portion of that rising water to exit 508, and/or be ejected from, the inertial wall tube through an upper pressure-relief nozzle 509, with the water so ejected tending to form an aerosol (which may promote cloud formation). Whether or not the pressure-activated, pressure-relief valve is open, the portion 510 of the inertial water tube that extends above the upper mouths (not visible, but positioned adjacent to the interior of the water reservoir 507) of the inertial water tube, through which water may exit the inertial water tube and enter the water reservoir, will tend to contain air and the compression of that air (e.g., when the pressure-relief valve is closed, and the air at the top of that portion 510 of the inertial water tube is trapped) will tend to occur in response to the water rising above the upper mouths of the inertial water tube, and that pocket of air will tend to act as a shock-absorbing buffer or cushion. By smoothly, gently, gracefully, and/or gradually, countering the upward acceleration of upwelling water within the inertial water tube, the air pocket in the upper portion 510 of the inertial water tube will tend to reduce structural stress, fatigue, and damage that might otherwise result from a sudden collision of upward rising water against a rigid surface.
If the water rises within the inertial water tube with enough force to rise above the upper mouths, then either the pressure-relief valve will open thereby allowing a portion of rising water to escape the inertial water tube, and thereby tending to relieve and/or reduce at least a portion of the pressure of the water rising in the inertial water tube, of the pressure-relief valve will remain closed, in which case the pocket of air trapped within the inertial water tube, adjacent to the pressure-relief valve, will tend to be compressed and thereby absorb and/or dampen at least a portion of the pressure of the water rising in the inertial water tube.
Water within the reservoir 507 tends to flow and/or drain back into the body of water 501 on which the embodiment floats through one of three effluent pipes fluidly connected to the water reservoir. One centermost effluent pipe (not visible) contains a water turbine (not visible) that tends to receive rotational kinetic energy and/or angular momentum from the water that flows through it from the water reservoir. The water turbine is operatively connected to a generator 511 that tends to generate electrical energy in response to the rotation of the water turbine. After passing through the water turbine, water flowing out and/or back into the body of water 501 through the centermost effluent pipe will tend to generate thrust that tends to propel the embodiment in a forward direction (e.g., in a direction approximately toward the left and into the page with respect to the embodiment configuration illustrated in
Water within the water reservoir 507 is allowed to flow, or prevented from flowing, through one or both of two lateral effluent pipes (not visible). Effluent regulation motors 512 and 513 raise and/or lower respective stoppers or plugs (not visible) that, when raised, allow water to flow through the respective lateral effluent pipes, or, when fully lowered, prevent such flow. In energetic wave climates, when water is ejected from the inertial water tube, and thereby injected into the water reservoir at a rate that exceeds the nominal and/or desired value, then water can be caused (e.g., by the embodiment's control system—not shown) to flow out of the water reservoir 507 through one or both of the lateral effluent pipes thereby generating (additional) forward thrust that will tend to propel the embodiment in a forward direction (e.g., in a direction toward the left and into the page with respect to the embodiment configuration illustrated in
By releasing water from the water reservoir 507 through two lateral effluent pipes in addition to the centermost effluent pipe, water may be released from the water reservoir at a faster rate than might otherwise be achieved through the release of water only through the centermost effluent, thereby perhaps avoiding an overflow of the water reservoir, and also thereby perhaps providing additional forward thrust and speed in a wave climate where additional speed might be helpful in maintaining the embodiment's most desirable course and direction. In the event that the release of water from the water reservoir 507 through all three of the effluent pipes is unable to avoid the overfilling of the reservoir, then water may flow out of the water reservoir 507 through apertures 514 positioned about an upper portion of the water reservoir wall.
In conjunction with the generation of forward thrust through the release of water from the water reservoir 507, the embodiment utilizes a rudder 515, the angular orientation of which is controlled by a motor 516, which, in turn, is controlled by the embodiment's control system (not shown) in order to steer a course that is determined and executed by that control system.
A portion of the electrical energy generated by the generator 511 is used to energize a plurality of computing devices, circuits, modules, and/or systems positioned, stored, enclosed, and/or protected, within a computer chamber, enclosure, box, housing, locker, cavity, and/or compartment 517. A portion of those computing devices execute computational tasks for which the tasks, programs, codes, parameters, and/or data, are received from a remote computer, network, transmitter, and/or antenna via encoded electromagnetic signals received by the embodiment's phased array antenna 518. A portion of the results, data, values, products, and/or information, generated through and/or by the execution of such remotely-received computational tasks are transmitted to a remote computer, network, receiver, and/or antenna via encoded electromagnetic signals transmitted by the embodiment's phased array antenna 518. Computational task and/or result data might be received from, and/or transmitted to, any of a variety of remote systems, computers, networks, transceivers, and/or antennas, including, but not limited to, those incorporated within and/or accessed via: satellites, surface drones, flying drones, balloon drones, terrestrial stations, boats, planes, and submarines.
The embodiment's control system (not shown) steers the embodiment through its control of the rudder control system 516 and its rudder-turning motor, which rotates shaft 521 to which rudder 515 is fixedly attached.
Because water is flowing out of lateral effluent pipe 520, but not out of lateral effluent pipe 525, the unbalanced and/or tangential component of the thrust generated by the water flowing out of lateral effluent pipe 520 will tend to generate a torque on the embodiment, about a centermost longitudinal axis, thereby tending to cause the embodiment to rotate in a clockwise direction (if viewed from above the embodiment). However, the embodiment's control system (not shown) can correct for this, or augment it, through its control of the rudder's 515 angular orientation (about the longitudinal axis of its shaft 521 (in
Within the cylindrical outer tube 503 is an inertial water tube 526 that includes a bottom-most cylindrical portion, a middle frusto-conical portion, and an upper cylindrical portion. As the embodiment moves up and down in response to waves passing across the surface 501 of the body of water on which the embodiment floats, water moves 505 into and out from the lower mouth 506 of the inertial water tube 526, and water 527 within the inertial water tube 526 likewise moves 528 up and down. Occasionally, water rises within inertial water tube 526 with sufficient energy, speed, and/or momentum to raise the upper level 527 of that water up to, and/or above, the upper mouths 529 of the inertial water tube, thereby causing a portion of that rising water to pass from, and/or be ejected by, the inertial water tube 526, into the water reservoir 507, thereby, at least momentarily, raising the level 530 of the water within the water reservoir 507.
If the water rising in the inertial water tube 526 is so great that the rate of up flow exceeds the rate at which water flows into the water reservoir through upper mouths 529, then the water that rises above those upper mouths may trap a pocket of air within the upper portion 510 of the tube 526, and with further rising of the level 527 of the water within the inertial water tube 526 the air within that air pocket may be compressed thereby exerting a counterforce upon the rising water, and thereby tending to cause its deceleration. If the resulting rate of deceleration in the up flow is insufficient to dissipate the momentum of the rising water to a sufficient degree, then a pressure-actuated valve 531 will open and allow a portion of the rising water to escape 508 through nozzle 509 as a spray, potentially creating an aerosol useful in the promotion of cloud formation, and cooling of the Earth.
Another embodiment utilizes a valve 531 that is opened and closed in response to the control signals generated by the embodiment's electronic or fluidic control system. In one such embodiment, the valve 531 is actuated through the variation of an electrical signal, voltage, and/or current, controlled, adjusted, and/or set, by the embodiment's control system.
A portion of the water within the water reservoir 507 flows into an effluent pipe 523 and passes over and/or through a water turbine 532 therein. As water from the water reservoir 507 flows through water turbine 532 a torque is applied and/or imparted to the water turbine. That water turbine torque is shared with a shaft 533 that is operatively connected to a generator 511. The rotation of water turbine 532 by water flowing under pressure from the water reservoir, results in the generation of electrical energy. After passing through the water turbine 532, the water flowing through effluent pipe 523 flows out of the pipe at effluent pipe discharge mouth 534 and thereby flows 535 out and/or into the body of water 501 on which the embodiment floats in an approximately horizontal direction thereby tending to generate forward (i.e., to the left with respect to the embodiment configuration and orientation illustrated in
Within a middle portion of cylindrical outer tube 503B is buoyant material 536, positioned between the wall of the cylindrical outer tube 503B and the wall of the inertial water tube 526, which provides the embodiment with a degree of permanent buoyancy. Above the buoyant material 536, and within the hollow gap between the wall of the cylindrical outer tube 503B and the wall of the inertial water tube 526, is water ballast 537, the volume and mass of which may be altered by a pump (not shown) that is able to pump additional water into the hollow gap and increase the volume of the water ballast, thereby tending to increase the draft of the embodiment, and is able to pump water from the water ballast to the water 501 outside the embodiment, thereby tending to decrease the draft of the embodiment. By adjusting the embodiment's amount of water ballast 537, the embodiment's control system (not shown) is able to adjust the embodiment's average mass, its average inertia, its average draft, its average displacement, and its waterline. The embodiment's extraction of energy from passing waves may be optimized with appropriate adjustments of the embodiment's inertia.
A portion of the electrical power generated by generator 511 is used to power some or all of the computing devices 538, circuits, modules, and/or systems positioned, stored, enclosed, and/or protected, within a computer chamber, enclosure, box, cavity, and/or compartment 517. A portion of the heat generated by those computing devices 538 may be conductively communicated and/or transferred to the air outside the embodiment.
Within the outer cylindrical wall or casing 503 is an inertial water tube 526. The inertial water tube has an approximately cylindrical bottom portion 539, a middle approximately frusto-conical portion 526, and an approximately cylindrical upper portion 540. At an upper end of the upper cylindrical portion 540 of the inertial water tube are a plurality of apertures 529 through which water that rises high enough within the inertial water tube is ejected, and/or flows, into the water reservoir 507.
In addition to the effluent pipe 523 through which water from water reservoir 507 flows back into the body of water on which the embodiment floats, a pair of lateral effluent pipes, e.g., 525, allow water from the water reservoir 507 to flow back into the body of water on which the embodiment floats generating thrust in the process. When a stopper or plug, e.g., 541, is in its lowered and/or closed position (i.e., as illustrated by plug 541 in
Between the walls of the inertial water tube 539/526/540 and the outer cylindrical tube 503 is a hollow space 542, chamber, and/or cavity, in which water may be deposited and/or trapped as water ballast.
Some of the water that rises far enough inside the inertial water tube 526 is ejected from, and/or spills into, the water reservoir 507 and is trapped there as a pool 530 of water with substantial head pressure and gravitational potential energy relative to the surface 501 of the body of water on which the embodiment floats. Water 530 inside the water reservoir 507 returns, and/or flows back, to the body of water 501 through three effluent pipes 520, 523, and 525. Water continuously flows from the water reservoir 507 through a centermost effluent pipe 523 within which it engages, energizes, and tends to cause to rotate a water turbine 532 positioned therein. The water turbine 532 in turn rotates a turbine shaft (533 in
Water can flow out of the water reservoir 507 through two additional effluent pipes 520 and 525 if and when respective pipe stoppers or plugs 543 and 541 are raised from their respective upper effluent pipe mouths 544 and 545. In the embodiment configuration illustrated in

Embodiment 600 floats adjacent to the surface 601 of a body of water. And, when in operation, embodiment 600 moves up and down in waves moving across the surface 601 of the water on which it floats, and it generates electrical power from the rotation of a water turbine (not visible) positioned inside a turbine-generator assembly, compartment, and/or housing 602.
A portion of the electrical power generated by the embodiment is used to energize and/or operate a computer array (not visible and positioned within a chamber below and adjacent to the turbine-generator assembly 602) and a phased array antenna 603. In one embodiment, the computer array processes computational tasks that the embodiment 600 receives by radio signals transmitted to, and converted into electrical signals by, its phased array antenna 603, or performs computational operations using input data that the embodiment 600 receives by radio signals transmitted to, and converted into electrical signals by, its phased array antenna 603. In one embodiment, the embodiment and/or its computers return computational results to a computer and/or computer network on land by radio-encoded versions and/or analogues of those computational results transmitted to a remote antenna, flying drone, balloon-suspended antenna/transceiver, satellite, or other receiver, by its phased array antenna 603.
Embodiment 600 includes several functional and/or structural elements including, but not limited to: a hollow flotation module 604/605 (having an approximately spherical-cap-shaped lower flotation module surface 604 and an approximately spherical-cap-shaped upper flotation module surface 605); a tube jacket wall 606; tube ballast (not visible, and positioned inside a tube ballast void between the inertial water tube 625 and the tube jacket walls 606/614); a turbine-generator assembly 602; an air pump 607; a turbine ingress pipe 608; an effluent pipe 609; an effluent pipe discharge mouth (not visible, and located in and/or passing through, tube jacket wall 606); a phased array antenna 603; a plurality of radial structural support fins 610; an inertial water tube (not visible, and located within hollow flotation module 604/605 and tube jacket wall 606, having an upper mouth at its top and a lower mouth at its bottom, and from which wave-induced ejections of water enter into, and are stored within, hollow flotation module 604/605), a pressure-relief tube 611, and several other elements that will be identified and discussed in subsequent figures.
Radial structural support fins 610 are connected to hollow flotation module 604/605, and tube jacket walls 606/614, and provide structural support to tube jacket walls 606/614 (and to the inertial water tube contained therein).
Hollow flotation module 604/605 is a broad, and/or large-diameter, upper structural component of the embodiment, and has an approximately spherical or ellipsoidal curvature, with an approximately spherical bottom surface 604.
Hollow flotation module 604/605 is substantially hollow and its walls are substantially hermetically sealed with the exception the inertial water tube (not visible), concentrically enclosed inside of tube jacket 606/614, is fluidly connected to the body of water 601 on which the embodiment floats. As shown and described in detail in subsequent figures, the inertial water tube (not visible) creates a passageway between the water below the embodiment (below the lower mouth (not visible) of the inertial water tube) and the interior of the hollow flotation module 604/605, and enables water to be “pumped” into the hollow interior of the hollow flotation module, when wave-induced oscillations of the water within the inertial water tube achieve sufficient energy, height, and/or momentum to escape and/or to be ejected by the upper mouth of the inertial water tube.
Between the wall of the inertial water tube (not visible) and the wall of the tube jacket 606 is a substantially hollow, preferably rigid, enclosure that is concentric with the inertial water tube (not visible) and substantially traps, encloses, and/or holds, therein a volume of water (e.g. seawater), i.e., a tube ballast, adjacent to a bottom portion of the inertial water tube (not visible), thereby providing additional mass (inertia) to the embodiment without substantially adding to its wet weight (i.e., the weight of the embodiment when dry and/or free of any water less the weight of the water displaced by the embodiment's dry portions). In some embodiments, a part of the tube ballast consists of and/or contains an additional volume of material denser than water, e.g. rock, iron, steel, aggregate stone or gravel, or concrete, in order to provide additional hydrostatic stability to the embodiment.
When in operation, the up and down motions of the embodiment due to the motion of waves acting on and/or against the embodiment cause water in the embodiment's inertial water tube (not visible and substantially inside the tube jacket 606/614) to periodically and/or occasionally be forced upward, and to be ejected into the hollow interior of flotation module 604/605. This periodic pumping of water, from the body of water 601 on which the embodiment floats, into the interior of the hollow flotation module 604/605 via the inertial water tube tends to raise and/or increase the average pressure of the water and gas inside the hollow flotation module. When the pressure of the air and water trapped inside the hollow flotation module is sufficiently great, then water trapped, cached, and/or stored, within the interior of the hollow flotation module 604/605 tends to rise up from the interior of the hollow flotation module through turbine ingress pipe 608 and therethrough to flow into turbine generator assembly 602, where it tends to flow through, and/or to cause the rotation of, a water turbine therein (not visible). And, having passed through, and imparted energy to, the water turbine, the risen water then tends to flow downwardly through turbine effluent pipe 609 and emerge from effluent pipe discharge mouth (not visible; penetrates through the tube jacket wall 606) into the body of water 601.
The thrust generated by the exit of water from the effluent pipe discharge mouth (not visible) and into the body 601 of water causes the embodiment to move through the body of water 601 in a direction substantially opposite that of the water outflow and/or discharge.
An embodiment of the present disclosure includes, incorporates, and/or utilizes, “steering elements” including, but not limited to, multiple effluent pipe discharge mouths (whose relative flow magnitudes can be controlled and/or adjusted e.g. using a valve and/or using variations in the torque of an operationally connected water turbine), and a pair of rudders. The embodiment can utilize its steering elements to propel and steer the embodiment in a specific direction, and/or to a specific location. In a similar embodiment, an electrical control system controls the steering elements in order to maintain and/or adjust the position of the embodiment in response to electromagnetically encoded signals and/or instructions received by a phased array antenna.
The embodiment's turbine-generator assembly 602, computer chamber (not visible), and air pump 607, are all contained on and/or within a removable spar module 612 which incorporates pad eyes, e.g., 613, that facilitate the placement and/or removal of the removable spar module 612 by a ship crane or aircraft, e.g. for servicing or replacement. In some embodiments, the removable spar module's removal is limited or prevented by an electronically controlled locking mechanism. In some embodiments, the electronically controlled locking mechanism is controlled by a computer that receives electromagnetically encoded instructions via the respective embodiments' phased array antennas, e.g. signals that are sent from a land-based control center or a maintenance vessel to unlock the removable spar module at a time corresponding to the presence of said maintenance vessel in the vicinity of the embodiment.
In the embodiment 600 illustrated in
In some embodiments, the horizontal diameter of hollow flotation module 604/605 may be 30 meters, 40 meters, 50 meters, 60 meters, or 70 meters. In some embodiments, the vertical height of the embodiment, from the top of hollow flotation module 605 (e.g. at the turbine-generator assembly 602), to the lower mouth 619 of the inertial water tube, may be 100 meters, 130 meters, 160 meters, 190 meters, or 220 meters.
In some embodiments, a different type of antenna, i.e., other than a phased array, and/or a different means of transmitting and/or receiving coded signals, computational tasks, and/or other forms and/or types of data, is used in place or, or in addition to, a phased array antenna. For instance, a dipole antenna or a satellite dish may be used.
Turbine-generator assembly 602 includes a generator 615 that is operatively connected to the water turbine (not visible) inside the turbine-generator assembly 602.
Water from within the hollow flotation module 604/605 flows up and into the turbine-generator assembly 602 through ingress pipe 608, and imparts energy to the water turbine therein (not visible) and causes it to rotate. Water discharged from the water turbine flows out of the turbine-generator assembly 602 through effluent pipe 609 and thereafter exits through effluent pipe discharge mouth 616, thereby leaving the embodiment 600 and entering the body of water 601 on which the embodiment floats, and thereby tending to generate thrust that tends to move the embodiment 600 in a “forward” direction (i.e., to the left in the embodiment configuration and/or orientation illustrated in
As the embodiment 600 moves up and down in response to waves passing across the surface 601 of the body of water on which the embodiment floats, water enters and leaves 618 a lower mouth and/or aperture 619 in the inertial water tube (not visible and inside, and substantially coaxial with, the tube jacket 606/614).
If the pressure of the air and/or water within the hollow flotation module 604/605 exceeds a threshold pressure, then pressurized water from within the hollow flotation module will tend to be ejected 620 from an upper mouth and/or aperture in a pressure-relief pipe 611 thereby relieving and/or reducing that pressure, and potentially preventing damage to the embodiment that might otherwise result from an excessive pressure within the hollow flotation module.
The individual dipole antennas of which the embodiment's phased array antenna 603 is comprised are visible on a top surface of the hollow flotation module 605. Each individual antenna element 621 (e.g., each dipole antenna) of the phased array antenna 603 is mounted to a mounting plate 622 which secures it to the hollow flotation module 605. Phased array antenna 603 enables electromagnetically encoded transmissions to be sent from, and received by, the embodiment to remote antennas, e.g. the antenna(s) of a satellite.
The individual antenna elements, e.g., 621, of the phased array antenna 603 are arranged radially around the embodiment's central removable spar module 612. The phased array antenna 603, the removable spar module 612, the hollow flotation module 605, and the inertial water tube (not visible), share, at least to an approximate degree, a common flow-normal and/or vertical longitudinal axis (i.e., normal to the page and at the approximate center of the circular perimeter 600 of the embodiment with respect to the orientation of the embodiment illustrated in
The air pump 607, when activated, pumps pressurized air into the interior of the hollow flotation module 605 through air pipe 623. Air pump 607 can be used to increase the mass and/or pressure of air inside the interior chamber, and/or enclosure, of the embodiment 600. Air pump 607 can be powered, at least in part, by electricity generated by turbine-generator assembly 602, electricity generated by a solar panel (not shown), and/or it can be directly mechanically driven by the rotating water turbine of turbine-generator assembly 602, or by any other means, mechanism, and/or source of electrical power.
Pressurized water from within hollow flotation module 605 is forced up, as a consequence of its pressure, through turbine ingress pipe 608 whereupon it flows through, engages, and causes to turn, a water turbine (not visible) inside turbine-generator assembly 602, which, in turn, causes the rotor of an operatively connected generator 615 to turn, thereby generating electrical power in response to the passage of water through the water turbine. Effluent from the water turbine flows out of the turbine-generator assembly 602 through effluent pipe 624. Water flowing out of the water turbine through effluent pipe 624 flows down and into a heat-exchanging, and/or heat-absorbing, cooling chamber (not visible) located within the removable spar module 612 and positioned directly beneath the upper wall of the removable spar module and the turbine-generator assembly 602 thereon. After flowing through the cooling chamber, the water turbine effluent flows up and into effluent pipe 609, and therethrough down to effluent pipe discharge mouth (616 in
As the embodiment moves up and down in response to the passage of waves across the surface 601 of the body of water on which the embodiment floats, water moves 618 in and out of a lower mouth 619 of the embodiment's inertial water tube 625. The water inside inertial water tube 625, as well as the upper surface 626 of that water, moves 627 up and down in response to the passage of waves at, around, and/or beneath, the embodiment. Occasionally, the surface 626 of the water inside the water tube 625 rises so high, and/or with such speed, momentum, and/or kinetic energy, that it escapes an upper mouth 628 of the inertial water tube 625 and collides with a water diverter 644 and is diverted 630 laterally such that it tends to fall into the hollow 631, and/or interior space, enclosure, and/or chamber, within the hollow flotation module 604/605, thereby adding water to a water reservoir and/or pool 632 of water therein.
Inertial water tube 625 is a substantially cylindrical tube and is concentric and/or coaxial with both the cylindrical tube ballast wall 606 and the oblong tube ballast wall 614. Inertial water tube 625 passes vertically through, and/or within, the center of tube ballast jacket 606/614. Inertial water tube 625 is open to the body of water 601 on which the embodiment floats at lower mouth 619, such that the interior of inertial water tube 625 communicates with the water outside (e.g. below) the embodiment, and water can pass freely 618 into (upwardly) and out from (downwardly) inertial water tube 625 via lower mouth 619.
As a consequence of the ejection of water from the upper mouth 628 of inertial water tube 625, and its subsequent addition to the interior hollow, chamber, and/or enclosure 631 of the hollow flotation module, and/or the addition of pressurized air to the interior hollow, chamber, and/or enclosure 631 by air pump 607, and/or the addition of both, the pressure of both the air (occupying the upper portion of the hollow flotation module's interior hollow, chamber, and/or enclosure 631 that lies above the surface 632 of the pool of water therein) and the water 632 within that hollow, chamber, and/or enclosure 631. The pressure of the water 632 causes water to flow 633 into, and up through, the lower mouth 634 of that portion 635 of the turbine ingress pipe 608 that is connected, via pipe coupler 636, to that portion 608 of the turbine ingress pipe that is directly connected to turbine-generator assembly 602. The water flowing up through turbine ingress pipe 635/608 flows into, onto, and/or through, water turbine 651 thereby tending to cause that turbine to rotate.
Hollow flotation module 604/605 contains a hollow, chamber, enclosure, vessel, and/or void 631 that can contain quantities of water 632 and/or air (above the water 632) at various pressures, including pressures significantly elevated from atmospheric pressure. Hollow flotation module void 631 has a top interior surface defined by the upper hollow flotation module wall 605, and a bottom interior surface defined by the lower hollow flotation module wall 604 of the flotation module.
Following its passage through water turbine 651, the water that reached the water turbine via turbine ingress pipe 635/608 flows out of the turbine-generator assembly through effluent pipe 624 and therethrough down and into a water cooling chamber 637 where it will tend to absorb at least a portion of the heat generated by computers, batteries, power converters, radio transceivers, phased-array controllers, and other electronic and/or electrical components and/or circuits 638, that are positioned, affixed, mounted, and/or protected, within computer chamber 639.
After its passage through the water cooling chamber 637, the water that reached and flowed through the water turbine 651 via ingress pipe 635/608 flows out through the upper portion 609 of the effluent pipe, and then, via pipe coupler 640, through the lower portion 641 of that effluent pipe, after which it exits 642 the pipe via effluent pipe discharge mouth 616, thereby generating thrust in a direction opposite that of its exit flow. Rudder 617 allows an embodiment navigational control system (not shown) to direct the motion of the embodiment 600 across the surface 601 of the body of water on which the embodiment floats thereby steering the embodiment along a desirable and/or specified course, and/or to a desirable and/or specified destination.
Turbine-generator assembly 602, effluent pipe 624, the upper portion 608 of the ingress pipe, the upper portion 609 of the effluent pipe, air pump 607, water cooling chamber 637, and computer chamber 639 (and the computers 638 and other electrical circuits therein), are attached to, and/or incorporated within, removable spar module 612. And, removable spar module 612 is positioned within and removably attached to removable spar enclosure 640.
If and when movable pipe connectors 636 and 640 are loosened, moved, and/or removed, the upper portions 608 and 609, of the respective ingress and effluent pipes, can be separated from their respective complementary lower pipe portions and/or segments 635 and 641 thereby permitting those respective upper and lower pipe portions to be separated. Similarly, although not visible in the illustration of
Aside from the rudder 617, and its associated mechanical components and/or systems, all of the moving (e.g., bearings) and electronic components of the embodiment 600 are incorporated within removable spar module 612. Thus, if any of those respective moving and electronic components fail, the damaged and/or non-functional removable spar module 612 may be replaced with an operational one. A pair of pad eyes (613 in
In normal operation, removable spar module 612 is locked inside its complementary removable spar enclosure 643 by an electronic locking mechanism that can be locked and unlocked by coded radio signals received by the embodiment's phased array antenna 603.
A bottom surface 644 of the removable spar enclosure 643 creates a water diverter. That bottom surface 644 has an approximately conical shape and tends to laterally divert 630 water that is ejected from the upper mouth 628 of water tube 625.
The inertial water tube 625 of the embodiment illustrated in
Inertial water tube 625 is defined by three continuous and mutually interconnected sections: a lower cylindrical section 625, a middle frustoconical section 645, and an upper cylindrical section 646. Lower cylindrical section 625 rises from lower mouth 619 up through the region about which is stored, entrained, and/or positioned, tube ballast 647, and through the bottom portion of flotation module 604.
When the embodiment 600 is in operation, and waves pass under and/or collide with the embodiment, water tends to move up and down within the inertial water tube 625. Water moving upward within and/or through lower cylindrical section 625 tends to accelerate, and/or to be accelerated, within the middle frustoconical section 645, and thereafter to move upward through the upper cylindrical section 646. Water that reaches the top of the upper cylindrical section 628 and has remaining upward velocity can leave water tube 646, and/or be ejected from it, whereupon it will tend to be laterally diverted by water diverter 644, so that it is deposited in the hollow, chamber, enclosure, vessel, and/or void 631 of hollow flotation module 604/605, whereupon it becomes “trapped” and typically cannot easily enter, and/or flow down, upper cylindrical section 628.
Continued wave action at and/or against the embodiment 600 can cause water to be periodically, occasionally, frequently, and/or somewhat regularly, pumped into interior enclosure 631, and to thereby be added to the reservoir 632 of water therein, which will tend to progressively, incrementally, and/or somewhat continually, raise the interior waterline 632 of the water deposited within the hollow flotation module 604/605. At the same time, the air or gas that is trapped with and/or alongside the water inside the hollow, chamber, enclosure, vessel, and/or void 631 is pressurized and compressed when water is added to the enclosure 631. As this air or gas is compressed, the pressure of the water in the enclosure also tends to be increased. At some point, as more and more water is added to the enclosure 631, and the pressure of the air and water within that enclosure 631 continues increasing, the pressure becomes sufficient to force water from the pool 632 into 633 the lower mouth 634 of the turbine ingress pipe, and up the turbine ingress pipe 635, to the point that it reaches and flows through the water turbine 651 within the turbine-generator assembly 602. Water flowing out of, and/or away from, the water turbine 651 through effluent pipe 609/641 tends to pull water up through turbine ingress pipe 608/635, and through the water turbine 651.
At the same time that water is added to the interior enclosure 631, tending to cause the pressure of the air and water within enclosure 631 to increase, the average density of the embodiment 600 tends to increase, thereby tending to cause the device to sit lower in the water which tends to reduce the effective and/or net head pressure required to drive water through the water turbine and back to the body of water 601 on which the embodiment floats, thereby tending to increase the rate at which water is evacuated from the embodiment.
The shape, dimensions, design, and/or geometrical configuration, of the inertial water tube is arbitrary and inertial water tubes with other shapes, dimensions, designs, and/or configurations are included within the scope of the present disclosure.

The water reservoir 632 occupies a lower portion of the hollow chamber 631 within the flotation module 604/605. However, that water reservoir extends down and surrounds the sides of the water tube 625 by occupying a space, chamber, and/or void, i.e., the tube ballast void 647, positioned and/or located between the wall of the bottom-most portion 625 of the inertial water tube and the wall of the surrounding and/or circumferential water tube jacket 606/614. The water 647 between the inertial water tube 625 and the tube jacket 606/614 is effectively tube ballast (i.e., ballast positioned adjacent to the inertial water tube 625). The tube ballast chamber 647 is contiguous and fluidly-connected to the water reservoir 632 and to the entire hollow chamber 631 within the flotation module 604/605.
A different embodiment of the present disclosure similar to the one illustrated in
Tube ballast 647 is located at the bottom portion of the embodiment 600 and is defined and/or constrained by walls 614/606 that are rigidly and concentrically attached to the outer circumference of the embodiment's inertial water tube 625 that passes vertically inside of it. The tube ballast walls 614 of tube ballast 647 have a curved and/or convex exterior shape. The horizontal cross-sectional area of tube ballast 647 is greatest at a vertical position that falls within the lower half of the embodiment (i.e. a vertical position located beneath the vertical midpoint of the embodiment). In a similar embodiment of the present disclosure, the horizontal cross-sectional area of tube ballast 647 is greatest at a vertical position that falls within the lower third of the embodiment. The scope of the present disclosure includes tube ballast chambers of any size, shape, relative position on the embodiment, and/or design.
Adjacent to a lower end of the inertial water tube 625, within a bottom portion of the tube ballast chamber 647, is a weight 648 and/or negatively buoyant material (e.g., rocks, sand, metallic objects, and/or other aggregate materials) that also serves as ballast for the embodiment 600.
Tube ballast wall 606/614 includes, creates, and/or comprises, a hollow container that serves as a jacket and/or wall that surrounds inertial water tube 625, especially but not exclusively jacketing a bottom portion of inertial water tube 625. Tube ballast wall 606/614 encloses and substantially constrains a large volume of water 647, “fixing” that water's vertical position relative to water tube 625 and therefore effectively adding the mass of that enclosed water to the mass of the embodiment. Tube ballast wall 614 defines a shape that corresponds to an elongated torus, whose central axis is nominally oriented vertically, with thin bottom annulus near 619, thin top annulus near 606, and bulbous center region near 614, so as to pass through the water with minimal drag (while providing the desired inertial ballast at the desired position along the inertial water tube).

Lower flotation module surface and/or wall 604 provides “permanent buoyancy” to the embodiment because it is thickened relative to the upper flotation module surface and/or wall 605 and either is made of a low-density material or contains hermetically sealed voids containing gas or a low-density material like closed-cell foam, in either case decreasing the average density of the embodiment. For instance, bottom flotation module surface and/or wall 604 might be made of closed cell foam. Or, bottom flotation module surface and/or wall 604 might include sealed bulkhead-separated compartments containing air, nitrogen, and/or other gases. In other words, bottom flotation module surface and/or wall 604 has an average density lower than that of water, and therefore contributes to an overall positive buoyancy of the embodiment. Other similar embodiments of the present disclosure include, incorporate, and/or utilize, permanent buoyancy that is located elsewhere on and/or in the embodiment. Some embodiments of the present disclosure include, incorporate, and/or utilize, a buoyant cladding or jacket around inertial water tube 625, especially around its middle frustoconical section 645. Some embodiments of the present disclosure have no structures, components, elements, features, and/or parts, that provide the respective embodiments with permanent buoyancy. These embodiments achieve positive buoyancy, and remain floating, as a result and/or consequence of, the air and/or other gas trapped, and/or forming a “bubble”, within hollow flotation module chamber 631.
The hollow flotation module 604 incorporates permanent buoyancy in the form of a material, structure, chamber, module, space, volume, and/or element, 649 from which water is largely, substantially, and/or completely, excluded. The illustrated embodiment 600 includes a volume 649 conformal to a bottom surface of the hollow flotation module 604 wherein water is substantially excluded.

Removable spar enclosure 643 is structurally stabilized, at least in part, by four approximately horizontal struts, e.g., 650, that rigidly connect it to the wall of the hollow flotation module 604/605, e.g., that connect it to the reinforced seam between hollow flotation module portions 604 and 605.
Embodiments including, incorporating, and/or utilizing, any number, geometry, design, configuration, strength, thickness, type, material composition, etc., of strengthening struts, stringers, and/or other structural reinforcements, used to stabilize an embodiment's removable spar enclosure and/or water diverter are included within the scope of the present disclosure.
Co-located with the turbine-generator assembly 602 is an array 638 of computers and/or other electronic components and/or circuits. Computer array 638 is located in a hermetically sealed computer container and/or chamber 639 and the computers and/or other electronic components and/or circuits within the computer array 638 are energized, at least in part, by electrical power generated by the embodiment and/or its generator 651.
Computer array 638 consists of computer chips (CPUs, GPUs, ASICs, or other similar chips) and other computer components at least some of which are bathed in a heat exchange fluid that has low electrical conductivity and tends to boil at a temperature corresponding to an operating temperature of the computer chips. This heat exchange fluid tends to rise as a gas to the top of the hermetically sealed computer chamber 639 when the computer array is in operation. A heat exchange surface at the top of hermetically sealed computer chamber 639 allows heat from the heat exchange fluid to be transferred to water that has traveled up turbine ingress pipe 635/608 and into and/or through cooling chamber 637. Accordingly the water moved by the embodiment to the turbine-generator assembly 602 is used, indirectly, to cool the computer chips of the computer array 638, via the intermediation of a phase-changing boiling heat exchange fluid in the hermetically sealed computer chamber 639. After receiving heat from the heat exchange fluid through the heat exchange surface that separates the computer chamber 639 from the cooling chamber 637, the water in the cooling chamber 637 flows through effluent pipe 609/641 and through effluent pipe discharge mouth 616. By this mechanism, heat generated by the embodiment's computer chips and other computer components is indirectly and/or passively discharged into the body of water 601 on which the embodiment floats.
In the embodiment illustrated in
In an embodiment of the present disclosure, the heat exchange surface of a cooling chamber (e.g., for the embodiment's one or more computer chambers) is positioned at or adjacent to an outer peripheral surface of the embodiment, and the water that is used to remove heat from the boiling heat exchange fluid within the embodiment's computer chamber is the water upon which the embodiment floats.
In an embodiment of the present disclosure, inertial water tube 625 is substantially longer/taller than in the embodiment configuration illustrated in

In some embodiments of the present disclosure, computer array 638 includes a plurality of CPUs, GPUs, TPUs, FPGAs, and/or ASICs that can to compute cryptographic hash values and/or other “proof of work” values for cryptocurrency block chain blocks. There are many methods, protocols, mechanisms, systems, and/or strategies, by which embodiments of the present disclosure may execute, complete, and/or process, the computation of cryptographic hash values and/or other “proof of work” values for cryptocurrency block chain blocks, and embodiments including, incorporating, and/or utilizing, any and/or all such methods, protocols, mechanisms, systems, and/or strategies are included within the scope of the current disclosure.
An embodiment of the present disclosure executes the following steps in order to compute cryptographic hash values:
When coordinating the cryptographic computational work of a plurality of such embodiments, the second computer can calculate a common block header specification from the plurality of cryptocurrency transaction records collected, collated, and/or processed, the by the first computer. It can then divide the total range of potential cryptographic hash values by specifying sequential, contiguous, and/or segmented, ranges of timestamp values, “nonce” values, and/or possible permutations of Merkle tree intermediate nodes, and transmit to each embodiment, and/or subset of embodiments, cooperatively searching for a cryptographic hash value, as part of a larger group, set, and/or collective, of such cooperating embodiments, a block header and/or computational task specification that will limit the searching of the embodiment, and/or subset of embodiments, to a specified range of potential cryptographic hash solutions, wherein optimally that range of potential solutions does not overlap, and/or is not redundant with, the ranges of potential solutions, searched, and/to be searched, by the other embodiments, and/or subsets of embodiments.
The range(s) and/or subset(s) of timestamp values, “nonce” values, and/or possible permutations of Merkle tree intermediate nodes, that an instance of an embodiment will be instructed to search, and/or that are sent to a given instance of an embodiment, might be chosen, e.g., by the second computer, an algorithm thereon, and/or a human operator, according to a “divide and conquer” scheme whereby a plurality of instances of embodiments are each given a different block header specification (or a block header specification at least some parts of which are conditionalized on, parameterized on, limited in scope by and/or narrowed with respect to, pre-designated embodiment-specific IDs), enabling the plurality of instances to simultaneously and efficiently search different parts of the “parameter space” of valid block chain block headers, thereby avoiding, at least to a degree, redundancy. Such a “block header specification” can also be referred to as a “partial block header specification” because it typically does not include concrete, immutable, and/or final values for all components of the block header, such as the nonce, timestamp, and/or Merkle root. Instead, it may contain ranges, parameters, and/or instructions, according to which the embodiment can vary these aforementioned components (and/or other components of the block header) in order to find and/or produce a block header whose cryptographic hash is valid (e.g. whose numerical value is less than the relevant “target”) with reference to the relevant block chain network's current difficulty level.
In some variants of the aforementioned method, and/or with respect to some embodiments of the present disclosure, the block header specification transmitted to the embodiment includes a set of cryptocurrency transaction records and may not necessarily include a Merkle root or a set of Merkle tree intermediate nodes. In these variants, the embodiment itself computes the relevant Merkle root from the set of cryptocurrency transaction records transmitted to it. In some variants, and/or with respect to some embodiments of the present disclosure, the embodiment is a node of the global Bitcoin network and receives transaction records directly from computers comprising said network.
A pressure-relief pipe 611 releases water from the water reservoir 632 inside the hollow flotation module 604/605 if and when the pressure of the air and water within the hollow flotation module is sufficient to lift the upper surface 652 of the water within the pressure relief pipe to a height that exceeds the height of the upper mouth 653 of the pressure-relief pipe. In other words, the height of the upper mouth 653 of the relief pipe 611 determines the maximum pressure of air and/or water that may be reached within the hollow flotation module 604/605. Water from the water reservoir 632 enters the pressure relief pipe 611 through a lower mouth 654. In some embodiments, the upper mouth 653 is fitted with a nozzle that can convert at least a portion of any water that escapes the pressure-relief pipe 611 into an aerosolized spray of water (e.g., of seawater).
Some embodiments of the present disclosure include, incorporate, and/or utilize, multiple pressure-relief pipes. Some embodiments of the present disclosure include, incorporate, and/or utilize a pressure-relief pipe 611 possessing a larger diameter and/or flow-normal cross-sectional area than that of the respective embodiment's turbine ingress pipe 635/608. Some embodiments of the present disclosure include, incorporate, and/or utilize a pressure-relief pipe 611 possessing a smaller diameter and/or flow-normal cross-sectional area than that of the respective embodiment's turbine ingress pipe 635/608. Some embodiments of the present disclosure include, incorporate, and/or utilize, at least one pressure-relief pipe that is fitted with an aerosolization nozzle and at least one relief pipe is not fitted with such a nozzle. An embodiment of the present disclosure includes, incorporates, and/or utilizes, multiple relief pipes and the upper mouth of one of the embodiment's relief pipes is at a higher vertical position and/or elevation than the upper mouth of a second of the embodiment's relief pipes.
The height of the upper mouth 653 of the relief pipe 611, and the related maximal pressure that may be achieved and/or maintained within a respective hollow flotation module 604/605, can be achieved, and/or is consistent, with many different embodiment configurations, and embodiments that include, incorporate, and/or utilize any and/or all such configurations and variations are included within the scope of the present disclosure. Some embodiments included within the scope of the present disclosure do not include a pressure relief pipe, nor any pressure relief mechanism, component, module, means, and/or system. Such embodiments may regulate the pressure of the water reservoirs 632 within their hollow flotation modules 604/605 by altering the torque and/or resistance of their respective water turbines 651, e.g., reducing the resistive torque of their respective water turbines so as to reduce their impedance and/or obstruction of the outflow of pressurized water. Some embodiments included within the scope of the present disclosure, include, incorporate, utilize, and/or rely upon, alternate mechanisms, components, modules, means, and/or systems, to prevent the possibility of excessive pressure from developing and/or persisting within their respective hollow flotation modules, e.g., such as with electrically actuated relief valves operated in conjunction with, and/or activated in response to, readings from pressure sensors within the flotation modules.
Pressurized air may be generated and/or produced by air pump 607 after which a portion of that pressurized air flows into the chamber, cavity, void, hollow, and/or interior 631, of the hollow flotation module 604/605, through an upper portion 655 and a lower portion 623 of an air pressurization pipe. The upper and lower pipe portions 655 and 623 of the air pressurization pipe are connected by pipe connector 656, which, if loosened, moved, and/or removed, will facilitate the separation, removal, and/or replacement, of the removable spar module 612 from its complementary removable spar enclosure 643.
The upper portion 646 of the inertial water tube is rigidly connected to the bottom of removable spar enclosure 643 by a plurality of struts 657.
During operation, the embodiment 600 moves up and down in waves due to the action of the wave pressure field of the body of water and/or the interaction of that wave pressure field with the embodiment, particularly the interaction of that wave pressure field with the broad bottom surface 604 of the hollow flotation module.
While the embodiment 600 moves up and down, the water contained within inertial water tube 625 has a large inertia and tends to resist being moved up and down in synchrony with the tube. When the middle frustoconical section 645 of inertial water tube 625 moves downward against the water contained within the inertial water tube 625, the pressure of the water within that inertial water tube 625 tends to increase and/or to be increased, especially within the upper region of lower cylindrical section 625. This higher and/or increased pressure tends to drive a portion of the water within the inertial water tube up through middle frustoconical section 645 of the inertial water tube, into and through the upper cylindrical section 646 of the inertial water tube, and, after being diverted by water diverter 644, out and into the interior chamber and/or enclosure 631 of the embodiment, where it tends to fall into, and/or to be captured by, the pool of water within the water reservoir 632, thereby tending to increase the volume and/or mass of the water within the water reservoir 632.
Embodiment 600 floats adjacent to the surface 601 of a body of water (e.g., of an ocean) when in an operational configuration. The average waterline of the embodiment may be at any of a range of locations along the vertical extent of the embodiment depending on the ratio of water to air inside flotation module 604/605 and/or the chamber 631 therein. In other words, the average density of the embodiment can be changed, controlled, altered, and/or adjusted, by changing, controlling, altering, and/or adjusting, the amount of water (e.g., seawater) that is contained within its hollow interior chamber 631 (e.g. inside hollow flotation module 604/605). These changes in average embodiment density can cause the embodiment's average vertical position within the body of water 601 on which the embodiment floats to change (and accordingly, they can cause its average waterplane area to change, as well as its degree of exposure and/or sensitivity to the dynamic pressure field in the water due to waves). The volumetric ratio of water to air inside and/or within 631 the hollow flotation module 604/605 can be altered by the rate at which water is permitted to flow through, and/or past, the embodiment's water turbine 651, as well as the volume and/or amount of pressurized air that is added to the interior 631 of the hollow flotation module 604/605 by air pump 607 via air conduit 655/623.
The lower and/or bottom wall 604 of the hollow flotation module 604/605 is continuous with tube jacket wall 606/614. Tube jacket wall 606 is cylindrical and has an approximately vertical longitudinal axis that is approximately coaxial with a longitudinal axis of the inertial water tube 625. Tube jacket wall 606 is spaced, separated, and/or offset, from the wall of the inertial water tube 625, and the intervening space and/or gap, defines and/or establishes the upper portion of the tube ballast void 647. When the device is in operation, the tube ballast void 647 can contain water (e.g., seawater). The water contained in tube ballast void 647 is continuous with the water 632 contained in the bottom portion of interior chamber 631 of the hollow flotation module 604/605 (in other words, water particles can move between the interior chamber 631 and the tube ballast void 647).
Tube jacket wall 606 is continuous with tube jacket wall 614. Tube jacket wall 614 is curved, convex, spaced, separated, and/or offset, from the wall of the inertial water tube 625, and tube ballast void 647 includes, and/or is defined as, the space between them; when the device is in operation, this tube ballast void 647 contains water (e.g., seawater). Tube ballast wall 606/614, the water 647 enclosed thereby, and solid ballast 649, and/or any subset of these, together constitute the embodiment's tube ballast.
Components above the upper wall 605 of the hollow flotation module are shown with dotted lines in order to better illustrate the path followed by water as it flows into, through, and then out of, the cooling chamber 637.
Water flows from the water reservoir (632 in
The removable spar module 612 is supported at an upper position on the hollow flotation module 605 by flange 612F, by which the removable spar module is also removably attached to the hollow flotation module.
Inside the computer chamber 639 are computers, batteries, power converters, radio transceivers, phased-array controllers, and other electronic and/or electrical components and/or circuits 638. In the spaces, gaps, and/or voids, 662 between these electrical components 638 is a phase-changing material that, after absorbing heat from the electrical components 638 volatilizes and rises within the computer chamber 639. The gasified phase-change material then tends to condense on the bottom surface of the cooling chamber which is above and adjacent to the computer chamber 639. As the gasified phase-change material within the computer chamber 639 condenses on the wall that is shared between the computer and cooling chambers it tends to transfer at least a portion of its heat to that wall. And, at least a portion of that transferred heat then tends to be absorbed and carried away from the shared wall by the effluent water flowing through the cooling chamber on its way back to the body of water on which the embodiment floats.
The removable spar enclosure 643 is structurally stabilized, at least in part, by struts 650 that affix it to the wall of the hollow flotation module 604/605.
The embodiment illustrated in
The scope of the present disclosure includes embodiments in which the flange 612F and/or the removable spar module 612 is attached, whether removably or permanently, to the other portions of the respective embodiments by explosive bolts, that, when detonated, e.g. as by a command transmitted to the embodiment by a satellite and received by the embodiment's phased array antenna, disconnect the spar module 612 from the portion of the embodiment to which it is attached, thereby permitting it to fall into the interior chambers and/or water reservoirs 632 of the respective embodiments and/or into the bodies of water 601 on which the embodiments float. Some embodiments that attach a removable spar module 612 to the embodiment with explosive bolts, also incorporate additional explosive bolts and/or panels which, when detonated, open the computer chamber 639 to the water (e.g., seawater) into which the spar module falls, thereby speeding the degradation of the computers and other electronic circuits therein. Embodiments that utilize explosive bolts may automatically and/or autonomously detonate some or all of those bolts when piracy, and/or an attempted breach, is detected, and/or when so instructed by a coded radio transmission received by the embodiments' respective phased array antennas.
Computer and/or electronic array 638 is indirectly cooled by water that has exited turbine-generator assembly 602. Computer array 638 consists, at least in part, of a number of computer chips enclosed in a hermetically sealed box, i.e., the computer chamber 639, that are bathed in a heat exchange fluid that can boil when heated by the computer chips and/or other electronic circuits. The gasified heat exchange (e.g., phase changing) fluid then condenses on a heat exchange surface 667, especially when said heat exchange surface is in contact with and cooled by water that has exited turbine-generator assembly 602 via the embodiment's heat exchange conduit, i.e., the cooling chamber 637. In some embodiments, heat exchange surface 667 is a flat metal surface. In some embodiments, heat exchange surface 667 includes of a series or array of pipes, ridges, or other features allowing a greater heat exchange surface between the heat exchange fluid inside the hermetically sealed computer chamber 639 box and the water flowing through heat exchange conduit, i.e., the cooling chamber 637.
The generator 615 of the turbine-generator assembly 602 produces electricity when the water turbine 651 is rotated by water. At least a portion of the electricity produced and/or generated by generator 615 powers the computers, batteries, power converters, radio transceivers, phased-array controllers, and other electronic and/or electrical components and/or circuits located and/or positioned within the computer array 638 via conductive cables passing from the generator of the turbine-generator assembly 602 to, and/or into, the computer chamber 639.
Embodiment 700 floats adjacent to the surface 701 of a body of water. And, when in operation, embodiment 700 moves up and down in response to the action of ocean waves impinging on, and/or colliding with, its surface as those waves move across the surface 701 of the body of water on which the embodiment floats. As it moves up and down in response to ocean waves, water within a partially tapered inertial water tube (not visible) at the embodiment's center moves up and down relative to the embodiment, said inertial water tube having a longitudinal and/or radial axis of symmetry that is oriented approximately vertically and/or approximately normal to the resting surface 701 of the water. A tapered upper portion of the inertial water tube causes a portion of the water moving upward within the tube to be raised to a height sufficient to cause a volume, and/or at least a portion, of the water flowing up the inertial water tube to be ejected from an upper mouth, aperture, channel opening, and/or orifice (not visible) in the inertial water tube.
Water ejected through an upper aperture of the embodiment's inertial water tube (not visible) tends to be deposited into a water reservoir (not visible) within the embodiment (i.e. within an interior chamber, hollow, void, and/or enclosure, thereof). Water within the embodiment's water reservoir is propelled, lifted, driven, and/or caused to flow, by a combination of pressures, including the head pressure of the water trapped within the embodiment, and the air pressure above and/or outside the water trapped within the embodiment, through a turbine ingress pipe 702 into a water turbine 703, thereby causing the water turbine to rotate and consequently causing the rotation of a rotor of an operatively connected generator 704, thereby causing electrical power to be generated.
Effluent from the water turbine 703 travels through effluent pipe 705 and therethrough into a computer chamber, compartment, and/or enclosure, 706 containing (not visible) electronic devices, components, mechanisms, modules, and circuits, including, but not limited to: computing devices, network routers, batteries, radio transceivers, encryption and decryption circuits, and memory storage devices and circuits. The effluent water flows through the computer chamber 706 through a portion of the effluent pipe therein, and that pipe is hermetically separated from the electronic circuits and components operated and/or operating within that computer chamber (thereby avoiding short circuits).
The effluent water passing through effluent pipe 705 tends to absorb heat from the electronic circuits within the computer chamber 706 and carry away at least a portion of that heat as that water flows out of, and/or exits, the computing compartment and continues flowing through effluent pipe 707 after which it flows out of the effluent pipe through effluent pipe discharge mouth 708 and returns to the body of water 701 on which the embodiment floats.
Effluent pipe 707 is secured to the embodiment by means of a rigid strut, brace, fin, rail, member, element, and/or component 709 that affixes the pipe to an outer surface 710 of the embodiment. The outer hull 710 of the upper bulbous portion (i.e., to the hollow flotation module) of the embodiment is structurally strengthened by means of a plurality of ribs, e.g., 711, which are approximately circular in shape and are attached and/or affixed to the outer hull of the embodiment's hollow flotation module and/or buoy portion such that a plane bisecting the upper and lower portions of each rib will be approximately normal to a flow-parallel and/or vertical longitudinal axis of the embodiment and/or of its inertial water tube.
Affixed to an upper surface 700 of the embodiment are seven arrays of antennas, e.g., 712, each array of rectilinearly positioned antennas comprises a phased array antenna, and the collection of radially disposed such phased array antennas comprises a larger composite phased array antenna.
Radially surrounding the embodiment's central inertial water tube (not visible) are a plurality of water ballast tubes, e.g., 713, each of which is open at a bottom-most end, e.g., 714, where an aperture, mouth, and/or orifice, permits water from the body of water 701 to freely move into and out of each ballast tube. An upper end of each ballast tube, e.g., 713, is adjustably and/or controllably opened to, or closed from the air and/or atmosphere above the embodiment 700 by an air valve, e.g., 716.
Each water ballast tube's air valve, e.g., 716, controls the opening and closing of a corresponding aperture, e.g., 717. When a ballast tube's air valve, e.g., 716, is open, its unobstructed aperture, e.g., 717, allows air to flow freely between the respective interior of the water ballast tube, e.g., 713, and the atmosphere. When a ballast tube's air valve is closed, the fully obstructed aperture, e.g., 717, of the water ballast tube traps the contents of the respective water ballast tube (e.g., by suction), thereby preventing the flow of air between the interior of the respective tube and the atmosphere, and tending to prevent, or at least to inhibit, the flow of water between the interior of the respective tube and the body of water 701 on which the embodiment floats.
An embodiment control system (not shown and located within computer chamber 706) opens a water ballast tube's air valve in order to allow the amount of air within the respective water ballast tube, and thereby the level of the water within the respective water ballast tube, to change in response to ambient waves, and to the wave-induced motions of the embodiment. When the amount of air within the respective water ballast tube is at a desirable level, and/or when the volume and/or mass of water within the respective water ballast tube is at a desirable level, then the embodiment's control system may close the respective water ballast tube's air valve, thereby tending to fix the level of the water within the tube, and thereby add the water trapped in the respective water ballast tube to the inertia of the embodiment, at least to a degree (since the water within a water ballast tube may still exhibit a small degree of oscillation through the consequent alterations in the pressure of the air trapped at the top of the water ballast tube). Through the exercise of such control, the embodiment's control system can achieve an advantageous level, volume, and/or mass, of water ballast within the embodiment's ballast tubes.
Water moves in and out of a lower mouth, aperture, and/or orifice 715 of the embodiment's centrally positioned inertial water tube.
After passing through the embodiment's water turbine, water discharged by the water turbine flows through effluent pipe 705 and effluent pipe 707 until it flows 716 through and out of an effluent pipe discharge mouth 708 positioned at a lower end of the effluent pipe 707 and thereby returns to the body of water 701 from which it was originally captured by the embodiment's inertial water tube (not visible).
Each of the embodiment's water ballast tubes, e.g., 717, allows water to freely enter and leave through a respective bottom mouth, aperture, and/or orifice, e.g., 718. The movement of water into and out of each respective water ballast tube is, at least to a degree, regulated, and/or controlled, through the opening and closing of a respective air valve, e.g., 719, positioned at an upper end of each respective water ballast tube. When open, the air valve permits air to move into and out of the respective water ballast tube, e.g., 717, thereby permitting the water therein to readily change its level in response to wave and embodiment motions. When allowed to move freely, the water within a water ballast tube has little effect on the inertia and/or vertical oscillations and/or movements of the embodiment. However, when closed, the air valve obstructs the flow of air therethrough thereby inhibiting the flow of air into and out of the respective water ballast tube, and thereby inhibiting changes in the level of the water within the tube. When prevented and/or inhibited from moving independently of the embodiment, the water within a water ballast tube tends to increase the inertia and tends to have a substantial inhibitory effect on vertical oscillations and/or movements of the embodiment.
Seven three-by-six rectilinear arrays of antennas, e.g., 712, comprise a composite phased array antenna that is affixed to an upper surface of the embodiment. Encoded electromagnetic signals are received by the phased array antenna and are processed by a transceiver (not shown) positioned within the embodiment's computer chamber 706. The phased array antenna 712, and the respective transceiver, are energized, at least in part, with electrical power generated by generator 704.
The encoded signals received by the phased array antenna 712 include computational problems, tasks, and/or data which are processed, at least in part, by computing devices and/or circuits within the computer chamber 706. At least a portion of the computational results and/or data generated by the computing devices within the computer chamber 706 (said results computed in response to the embodiment's receipt of electromagnetically encoded computational task specifications or commands) is encoded and transmitted by the phased array 712. The computing devices within the computer chamber 706 are energized, at least in part, with electrical power generated by generator 704.
A centrally-positioned inertial water tube 720 has a relatively large-diameter lower mouth 715 at its bottom end and a relatively small-diameter upper mouth 721 at its top end. A narrowing of the tube from its bottom end to its top end results in a relative reduction of flow-normal cross-sectional area of the top mouth 721 relative to the bottom mouth 715. The inertial water tube 715 is surrounded by nine water ballast tubes, e.g., 713 and 717. When the respective air valves, e.g., 716 and 719 in
Water within a centrally positioned inertial water tube 720, 722 and 723, is able to freely move 724 in and out of a lower mouth 715 of the tube, thereby freely moving between the interior of the inertial water tube and the body of water 701 on which the embodiment floats. Any air or water within the inertial water tube is also able to freely move out of an upper mouth 721 of the tube (thereby tending to be ejected from the tube and into the interior 730 of the embodiment). As the embodiment 700 moves up and down in response to passing waves, the surface 725 of the water within the inertial water tube 722 moves 726 up and down. Periodically, the surface 725 of the water within the inertial water tube 720, 722, 723, will rise above the mouth 721 and a portion of that water will be ejected from the tube 723. Water ejected from the upper mouth 721 of the inertial water tube 723 may be laterally deflected upon its collision with an approximately conical and/or pointed water diverter 727.
The water diverter 727 is formed within and/or by an inner upper hull, wall, structure, and/or surface 728. Above, and joined at an approximately circular seam 700 with, the inner upper hull 728 is an outer upper hull 729.
Water ejected from and/or through the upper mouth 721 of the inertial water tube 723 enters the interior 730 of the embodiment's hollow flotation module 710 and tends to accumulate and/or pool in a bottom portion of that interior chamber, enclosure, and/or space thereby tending to form a reservoir of water 731. As water accumulates in the embodiment's water reservoir 731 it tends to displace and compress the air above the water reservoir 731 within that interior space 730 thereby tending to increase the pressure of that air. Additionally, as the level 731 of the water reservoir rises above the mean level of the surface 701 of the body of water on which the embodiment floats, the height of the surface 731 of the reservoir above the surface 701 of the outside body of water creates a head pressure and/or gravitational potential energy.
Through a combination of air and head pressures, water within the embodiment's water reservoir 731 tends to be driven and/or pushed into a mouth 732 of turbine ingress pipe 702 after which the water tends to flow 733 upward through the pipe 702 and into 734 the water turbine 735 within the turbine compartment 703 thereby tending to cause the water turbine to rotate, and an operatively connected generator to generate electrical power.
Within a lower portion 736 of the interior 730 of the embodiment's hollow flotation module 710 is a permanently buoyant space 736, chamber, and/or material, characterized by a density that is lower than that of the water 701 on which the embodiment floats. This buoyant space 736 tends to reduce the likelihood that the embodiment will sink if the wall 710 of the embodiment's hollow flotation module is punctured, structurally compromised, and/or ruptured, which might tend to allow the interior 730 of the hollow flotation module to fill with water. A volume 736 of permanent buoyancy will tend to keep the embodiment afloat even if the ingress of water from the upper mouth 721 of the inertial water tube 723 is not countered and/or resisted by a corresponding increase in the pressure of the air within the buoy.
The embodiment 700 incorporates permanent buoyancy in the form of a material, structure, chamber, module, space, volume, and/or element, 736 from which water is largely, substantially, and/or completely, excluded. The illustrated embodiment 700 includes a volume 736 conformal to a bottom interior surface of the buoy 710 from which water is excluded.
Buoyancy space 736 may be made of a low-density material or may contain one or more hermetically sealed voids containing gas or a low-density material like closed-cell plastic foam, in either case decreasing the average density of the embodiment. For instance, buoyancy space 736 might be made of closed cell foam. Or, buoyancy space 736 might include sealed bulkhead-separated compartments containing air or another gas. In other words, buoyancy space 736 has an average density lower than that of water, so as to help provide an overall positive buoyancy to the embodiment.
Some embodiments of the present disclosure include, incorporate, and/or utilize, permanent buoyancy that is located elsewhere on and/or in those embodiments. Some embodiments of the present disclosure include, incorporate, and/or utilize, permanent buoyancy that is attached, connected, and/or incorporated within, those embodiments as a cladding or jacket around the lower portions of the water ballast tubes, e.g., 737. Some embodiments of the present disclosure have no permanent buoyancy; in which case those embodiments derive, and/or rely upon, a positive buoyancy exclusively from the “bubble” of trapped gas within the interior 730 of the hollow flotation modules 710 of the respective embodiments. Those embodiments may utilize the space 736 in order to extend and/or to expand the water reservoirs 731 of the respective embodiments.
Arrayed about the outer perimeter of the inertial water tube 720 are a plurality of water ballast tubes, e.g., 737, with vertical longitudinal axes that are substantially parallel to a vertical longitudinal axis of the inertial water tube. A lower mouth, e.g., 738, at a bottom end of each water ballast tube, e.g., 737, allows water to enter and leave, e.g., 739, each water ballast tube without restriction or hindrance. An air valve, e.g., 740, at a top end of each water ballast tube allows air to enter and leave, e.g., 741, each respective water ballast tube without restriction when the valve is in an open orientation and/or configuration. However, when an air valve, e.g., 740, is closed, e.g., 742, then air (and water) are obstructed and tend to be unable to enter or exit the respective water ballast tube, e.g., 737.
When a water ballast tube's, e.g., 737, air valve, e.g., 740, is open, air may flow 741 in and out of the respective water ballast tube. Each water ballast tube, e.g., 737, has an upper tube portion, e.g., 743, of relatively small diameter. The relatively narrow upper portion of each water ballast tube is contiguous, continuous, and/or fluidly connected, with a relatively wide lower portion, e.g., 737. When a water ballast tube's, e.g., 737, air valve, e.g., 740, is open, the relatively unrestricted inflow and outflow 741 of air into the upper portion of the tube allows the level 744 of the water within the respective water ballast tube to freely change and/or move in response to movements of the embodiment and/or the waves that move it. When a water ballast tube's, e.g., 737, air valve, e.g., 740, is closed, e.g., 742, the passage of air into and out of the upper portion of the tube tends to be obstructed, thereby trapping air therein. Such trapped air will tend to impede, inhibit, and/or prevent, any raising of the level 744 of the water within the water ballast tube, which will tend to compress the pocket of trapped air. Such trapped air will tend to impede, inhibit, and/or prevent, any lowering of the level 744 of the water within the water ballast tube, which will tend to create a partial vacuum within the pocket of trapped air.
Thus, when a water ballast tube's respective air valve is open, the volume and mass of water within that respective water ballast tube may change with relative freedom. However, when the embodiment's control system (not shown) determines that the level of water within a water ballast tube is optimal, desirable, and/or suitable, it may close the respective water ballast tube's air valve thereby inhibiting any changes in the volume and mass of water within that water ballast tube.
A lower portion of the centrally disposed inertial water tube 722-723 is obscured by the permanent buoyancy 736. The inertial water tube 722-723 is surrounded in a radial fashion by nine water ballast tubes 713, 717, 737, 745-750. The section plane passes through one of the embodiment's circular reinforcing bands 711 which helps to resist any expansion of the wall 710 of the hollow flotation module that might occur in response to an increase in the pressure of the air and water trapped within the internal chamber 730 bounded by the wall 710 of the hollow flotation module.
Effluent pipe 707 is secured, fastened, and/or affixed to the embodiment's hollow flotation module 710 by means of a strut 709 that spans the gap between the effluent pipe and the wall 710 of the hollow flotation module.
Effluent water from the water turbine 703 flows away from the water turbine through turbine egress pipe 705. A short distance from the water turbine 703, the effluent pipe 705 enters the computer chamber 706, and water flowing through the section and/or portion of pipe 751 positioned within the interior of the computer chamber will tend to absorb at least a portion of the heat generated by the computing and/or other electronic circuits, devices, components, and/or elements, within the computer chamber. The effluent pipe 751 then passes out of the computer chamber 706, and the heated water then flows out of the computing chamber 706 and into effluent pipe 707, after which that water flows 716 through and out of an effluent pipe discharge mouth 708 and thereby returns to the body of water 701 on which the embodiment floats.
Water pushed out of the water reservoir (731 in
Hollow flotation module 710 is a broad upper structural component of the embodiment, and has an approximately spherical or ellipsoidal curvature, with an approximately spherical bottom surface.
Hollow flotation module 710 is substantially hollow and its walls are substantially hermetically sealed with the exception of its connection to the body of water via inertial water tube (720 in
Some embodiments of the present disclosure include, incorporate, and/or utilize, respective hollow flotation modules 710 having respective horizontal diameters of 30 meters, 40 meters, 50 meters, 60 meters, or 70 meters. Some embodiments of the present disclosure are characterized by vertical heights, e.g., the distances from the tops of their respective flotation modules 710, to their respective lower mouths 715, of 100 meters, 130 meters, 160 meters, 190 meters, or 220 meters.
Some embodiments of the present disclosure include, incorporate, and/or utilize, different types of antenna, i.e., other than a phased array antenna, and/or different means of transmitting and/or receiving coded signals, instead of, and/or in addition to, a phased array antenna.
If the pressure of the air and/or water within the hollow flotation module 710 of the embodiment exceeds a threshold pressure, then pressurized water from within the water reservoir 731 of the hollow flotation module 710 will tend to be ejected from an upper mouth and/or aperture of the embodiment's pressure-relief pipe 702 thereby relieving and/or reducing that pressure.
Individual and/or constituent antennas (e.g., dipole antennas) of the embodiment's phased array antenna 712 are visible on the top surface of the embodiment's hollow flotation module 710. Phased array antenna 712 enables electromagnetically encoded transmissions to be sent from the embodiment to remote antennas, e.g. to the antenna(s) of a satellite, and to be received by the embodiment, e.g. from the antenna(s) of a satellite.
The shape, dimensions, design, and/or geometrical configuration, of the inertial water tube 720 is arbitrary and inertial water tubes with other shapes, dimensions, designs, and/or configurations are included within the scope of the present disclosure.

The scope of the present disclosure includes embodiments that include, incorporate, and/or utilize, any means, manner, element, component, design, and/or material, of excluding water from any portion of the embodiment and thereby creating to any degree a measure of permanent buoyancy. Embodiments possessing any measure of permanent buoyancy are included within the scope of the present disclosure regardless of the shape, dimensions, design, geometrical configurations, positions, distributions within the embodiment, relative volumes, absolute volumes, and material(s) of fabrication, of the buoyant features, components, elements, portions, and/or parts, by which that measure of permanent buoyancy is achieved.
In the embodiment illustrated in
The embodiment 800 floats adjacent to an upper surface of a body of water 801 over which waves pass. The embodiment comprises an upper buoyant portion (i.e., a hollow flotation module) 802 and a depending, rigidly connected tubular portion (i.e., an inertial water tube) 803 through which water rises and falls in response to the wave-induced changes in the height of the water's surface 801 and to the wave-induced movements of the embodiment.
The embodiment's hollow flotation module 802 encloses a sealed hollow chamber that nominally contains both air and water. The embodiment's hollow flotation module 802 has an approximately ellipsoidal shape from which an upper portion has been cleaved so as to form a relatively flat upper surface that is oriented so as to be approximately normal to a nominally vertical longitudinal axis of the embodiment's inertial water tube 803, and approximately parallel to a resting and/or mean surface 801 of the body of water on which the embodiment 800 floats. In other embodiments, hollow flotation module 802 has no cleaved portion or has a smaller cleaved portion, so that it more closely resembles a full ellipsoid, and its upper surface can be curved rather than flat.
The embodiment's inertial water tube 803 is open to the body of water 801 on which the embodiment floats by means of a lower aperture or mouth 804. And, the embodiment's inertial water tube 803 is open to the interior of the embodiment's hollow flotation module 802 by means of an array of upper apertures or mouths (not visible). A lower portion 805 of the embodiment's inertial water tube 803 is surrounded by, and/or positioned within, a water-filled tank, chamber, and/or jacket 805 which provides the embodiment with water ballast and additional inertia, which tends to alter the natural frequency of its oscillations.
The embodiment's inertial water tube 803 comprises a single channel of relatively great flow-normal cross-sectional area at its lower extent, e.g. 803 and the channel passing through tube ballast chamber 805. At its upper end 806, the tubular portion of the inertial water tube 803 is partitioned into an array of substantially parallel and tapered channels, whose cumulative flow-normal cross-sectional area narrows to become less than the flow-normal cross-sectional area of the tube's lower mouth 804. Thus, water rising within the embodiment's inertial water tube tends to pass through a constricting channel (i.e. an array of constricting channels that, in flow-normal cross-sectional aggregate, also constitute a constricting channel). Whereas, water moving downward within the inertial water tube tends to pass into an expanding channel.
As the embodiment 800 rises and falls in response to passing waves, the inertia of the water within its inertial water tube inertially resists the nominally wave-induced upward and downward accelerations of the embodiment 800, thereby causing the water within the inertial water tube to tend to move vertically and/or longitudinally relative to the inertial water tube that constrains and/or entrains it, and typically and/or often in a relative direction opposite that of the embodiment's movements.
Changes in the relative height of the water 801 outside the embodiment, e.g., changes in the height of the embodiment's waterline, result in changes in the effective depth of the inertial water tube's lower mouth 804, and/or in the magnitude of the pressure of the water at and/or adjacent to that lower mouth, which also tends to cause the water within the embodiment's inertial water tube 803 to move vertically and/or longitudinally relative to the tube 803. At least as a consequence of the two factors described above, the water within the embodiment's inertial water tube 803/806 tends to rise and fall within the inertial water tube's tapered channels when the embodiment rises and falls in response to passing waves.
As the water within the embodiment's inertial water tube 803 rises and falls, the relative narrowing and/or constriction of the tube's tapered channels tends to amplify the movements and/or speeds of movement of that water. Occasionally, the water within the embodiment's inertial water tube rises to an extent that causes a portion of that water to be ejected from, and/or to flow out of, one or more of the upper apertures or mouths of the inertial water tube's tapered channels, e.g., 806, thereby depositing water within the interior of the embodiment's hollow flotation module 802. As water collects within the embodiment's hollow flotation module 802, the air therein is displaced and compressed causing its pressure to increase. When the height of the water within the embodiment's hollow flotation module 802 is great enough, and/or the pressure of the air therein is great enough, water from within the embodiment's hollow flotation module 802 rises through a turbine ingress pipe 807 and enters a water turbine enclosure 808 where it collides with a water turbine therein (not visible), tending to cause the water turbine to rotate, and thereby tending to cause an operatively connected generator 817 to be energized, e.g., through a rotation of its rotor, thereby generating electrical energy.
After passing through, around, and/or over the water turbine within the water turbine enclosure 808, water flowing out of the embodiment's hollow flotation module 802 flows through effluent pipe 809, and then flows out of an end of that effluent pipe through a mouth or aperture (not visible) beneath the embodiment's hollow flotation module 802, where it rejoins the body of water 801 on which the embodiment floats. The outflow of water from the distal mouth of effluent pipe 809 tends to generate thrust that tends to propel the embodiment in a direction opposite the embodiment's rudder 810, thereby allowing the embodiment's control system (not visible) to direct the thrust-induced motion thereof so as to steer the embodiment in a desirable direction and/or to a desirable destination. The rudder's rotational orientation about the longitudinal axis of its substantially vertical shaft (not visible) is altered, changed, adjusted, positioned, and/or controlled, by a rudder control mechanism 811 that is controlled by the embodiment's control system.
The position, orientation, and structural integrity of the embodiment's inertial water tube 803/806, relative to the embodiment's hollow flotation module 802, is supported, augmented, facilitated, and/or promoted through a plurality of tensioning linkages, e.g., 812, that connect the two. Embodiments of the current disclosure may utilize tensioning linkages that are rigid, such as, but not limited to, pipes and struts, such as those made of steel or another metal. Embodiments of the current disclosure may also use and/or alternatively use tensioning linkages that are flexible, such as, but not limited to, chains, cables, ropes, and/or other linkages.
Affixed to an upper surface of the embodiment's hollow flotation module 802 is an electronics enclosure 813 whose contents can include, but are not limited to, computers, computing devices, computer networking devices, memory storage devices, energy storage devices, radio communications circuits, navigational devices, and the embodiment's control system. At least a portion of the electrical power that energizes some or all of these electronic devices and circuits is generated by the embodiment's water-turbine-powered generator 817. A portion of that electrical power may be stored within energy storage devices within the electronics enclosure 813 and made available to power some or all of the other electronic devices and circuits. At least a portion of the heat generated by the electronic circuits and devices is dissipated into the atmosphere by heat-radiating fins, e.g., 814, and as in previous embodiments of the present disclosure, by communicating some of that heat via a heat exchanger to one or more of: the water enclosed within the embodiment, the water passing from or to the turbine of the embodiment, and/or the water 801 on which the embodiment floats.
The embodiment's phased-array antenna 815 receives encoded radio transmissions that include, but are not limited to: computational problems, computational data, signals, coordinates, status requests, status updates, and other information that allows the embodiment to perform computational tasks on, with, and/or within, its computational devices; navigate to desirable locations (e.g., where wave conditions are and/or will be optimal, where the number and/or dangers of potential navigational hazards are and/or will be minimal, etc.); coordinate its navigation, position, computational activities, etc., with other embodiments; etc.
Likewise, the embodiment's phased-array antenna 815 transmits encoded radio transmissions that include, but are not limited to: the results of fully or partially completed computational tasks; reports of the embodiment's status (e.g., available electrical energy, and performance of devices, systems, and/or subsystems on, in, or within, the embodiment); reports of ambient environmental conditions (e.g., wave conditions, wind speeds and directions, precipitation, relative humidity, water temperature and salinity, current speed and direction, and positions, speeds and densities, of passing marine life); available computing resources (e.g., CPUs, memory, etc.) and estimates of future availability; and observations of nearby ships, planes, fish, etc.
An air intake valve 816 is controlled by the embodiment's control system (not visible) and, when opened, allows a suction created within one or more tapered channels 806 of the embodiment's inertial water tube to draw air into the interior of the embodiment's hollow flotation module 802, thereby tending to increase the mass of air therein. If the pressure of the air within the embodiment's hollow flotation module 802 exceeds a threshold level, then portions of that air will exit through a pressure-relief pipe (not visible).
Other embodiments have other types of generators, multiple generators, generators coupled to the water turbine by differing mechanisms, and so on. An embodiment of the current disclosure incorporates and utilizes a generator that is incorporated within, and/or is an integral part of, the water turbine. One such integral water turbine generator mechanism comprises a set of electricity generating coils embedded within a cylindrical coaxial block about the longitudinal and/or radial axis of which the water turbine, and magnets attached thereto, rotates.
When the volume and/or height of water within the interior of the embodiment's hollow flotation module 802 is sufficiently great and/or the pressure of the air within the embodiment's hollow flotation module is sufficiently high, water will tend to rise within turbine ingress pipe 807 and pass through, engage, and cause to rotate, the water turbine (not visible) positioned within the water turbine enclosure 808 after which the water will tend to flow through effluent pipe 809 and thereafter to flow 818 into the body of water 801 on which the embodiment floats through effluent pipe discharge mouth 819.
Rudder 810 is attached to rotatable shaft 820 the rotational orientation of which is adjusted and controlled by rudder control mechanism 811.
If and when the pressure of the air within the embodiment's hollow flotation module 802 exceeds the pressure of the water at the lower mouth and/or aperture 821 of the (air) pressure-relief pipe 822, a sufficient portion of that air will exit the embodiment 800 through that lower pressure-relief pipe mouth so that the pressure of the air within the embodiment's hollow flotation module 802 returns to its maximum nominal value. In a similar manner, a water pressure-relief pipe such as 611 in
As the embodiment 800, and the adjacent waves, rise and fall, water enters and exits 823 the lower mouth 804 of the embodiment's inertial water tube, thereby permitting the water within the inertial water tube to rise and fall without significant hindrance.
At the center of the annular-ring shaped tube ballast chamber 805 is the lower mouth 804 of the approximately cylindrical bottom-most portion of the embodiment's inertial water tube 803. A middle portion 803 of that inertial water tube constricts with respect to an upward vertical direction, and the inertial water tube progressively alters its flow-normal and/or horizontal cross-sectional shape from the approximately circular cross-section 804 that characterizes the cylindrical bottom-most portion of that inertial water tube and the lower mouth 804 thereof, to the approximately rectangular flow-normal cross-section 824 that characterizes the middle portion 803 of the embodiment's inertial water tube.
(It should be noted that throughout this disclosure the term “ballast” does not necessarily refer to, and typically does not refer to, heavy material such as stone or gravel, but rather typically refers to a “water ballast” i.e. a volume of water that is constrained within an enclosure of the relevant embodiment so as to add a measure of effective inertia, mass, and stability to the embodiment. So, for instance, tube ballast chamber 805 of embodiment 800 is a hollow enclosure having walls made of a rigid material e.g. steel and having an interior void that, in operation, is flooded with water, e.g., seawater.)
At an upper end 824 of the middle rectangular portion 803 of the inertial water tube, the single, integral inertial water tube and/or its channel splits and forms and/or becomes six approximately conical tapered channels, segments and/or portions, e.g., 825, whose flow-normal and/or horizontal cross-sections morph from approximately square 826 adjacent to their bases, bottoms, and/or lower extents, to approximately circular 827. At the upper end of each conical tubular segment is an approximately circular mouth 827, at their tops, and/or upper extents. Above each upper mouth, e.g., 827, of each conical tapered channel, e.g., 825, is a respective approximately conical water diverter, e.g., 828. Each water diverter tending to cause water ejected upward from its respective conical tapered channel to be directed and/or sprayed laterally, thereby reducing the portion of that water that will fall back into the respective conical tapered channel through the channel's respective mouth, e.g., 827, after ejection. In other embodiments, the array of progressively more constricted tubes at the upper portion of the undivided portion 803 of the inertial water tube can be arrayed in other configurations besides the “2×3” rectangular/rectilinear configuration characterizing the embodiment illustrated in
The scope of the present disclosure includes embodiments with any type, design, size, location, configuration, flow-normal cross-sectional profile, flow-parallel cross-sectional profile, and/or design, of tapered channel array.
The scope of the present disclosure includes embodiments including, incorporating, and/or utilizing, inertial water tubes possessing, incorporating, and/or manifesting, any number of separated channels, split channels, unique flow paths, sub-divided tubes and/or tube segments.
As the embodiment 800 moves up and down in response to passing waves, and as its waterline and effective draft also change and/or oscillate in response to passing waves, water tends to rise and fall within the embodiment's inertial water tube 829, 803, and 806. The rising and falling of water within the embodiment's inertial water tube is associated with a concomitant flowing in and flowing out 823 of water through the inertial water tube's lower mouth 804. The lower cylindrical 829 and middle constricting 803 portions of the inertial water tube are joined together, and/or transition from one to the other, at seam and/or junction 830. Between seams 830 and 831, the inertial water tube's flow-normal horizontal cross-sectional area decreases (with respect to an upward direction) and its shape morphs from approximately circular to approximately rectangular.
Above seam 831, the inertial water tube splits into six separate channels, e.g., 806, whose flow-normal cross-sectional areas also decrease with respect to an upward direction. The sectional plane of the illustration in
At an uppermost end of each conical tubular segment is an approximately cylindrical tube segment 833 through which water is occasionally ejected, e.g., 834, from and/or through the upper mouth, e.g., 827, of each respective conical tubular segment, and diverted by each respective approximately conical water diverter, e.g., 828. Each water diverter, e.g., 828, is formed at the end of a structural element, e.g., 835, that depends from the upper wall 836 of the embodiment's hollow flotation module 802. (In some embodiments, the water diverters do not depend from the upper wall 836, but are rather supported by, and/or rigidly attached to, one or more of the conical tubular segments, e.g. 833A, e.g. by attachment to the upper mouths 827 of one or more conical tubular segments.) Water ejected from the conical tubular segments 806/833 collects in a water reservoir 837 positioned within a lower portion of the interior space of the embodiment's hollow flotation module 802, thereby forming a reservoir of water the height of whose surface 838 defines and/or creates a head pressure of the water at a bottom mouth 839 of the turbine ingress pipe 807. The pressure of the water at the bottom mouth 839 of the turbine ingress pipe 807 is increased by the pressure of the air within the upper portion 840 of the embodiment's hollow flotation module 802.
When the combined and/or total pressure of the water at the bottom mouth 839 of the turbine ingress pipe 807 (i.e. pressure due to both the weight of water and degree of air compression above that location) is sufficient, water enters that bottom mouth 839, travels upward through the turbine ingress pipe 807, enters the water turbine enclosure 808, and causes the rotation of the water turbine 841 therein. After passing through the water turbine 841, the water propelled out of the embodiment's water reservoir 837 then flows through effluent pipe 809 and flows 818 through mouth 819 back into the body of water 801 from which it was originally captured by the embodiment's inertial water tube 829.
The bottom mouth 821 of pressure-relief pipe 822 is at a depth beneath the embodiment's hollow flotation module 802 that varies in response to changes in the waterline and/or draft of the embodiment, but which is nominally within a relatively narrow range of depths. When the pressure of the pocket of air 840, trapped within the hollow flotation module 802, and positioned above the water reservoir 837, exceeds the hydrostatic pressure of the water at the bottom mouth 821 of the pressure-relief pipe 822, then pressurized air from the air pocket 840 will flow through that pipe 822 and exit the pipe's lower mouth 821 thereby escaping the embodiment and reducing the pressure of the air 840. When the pressure of the pocket of air 840 is less than the hydrostatic pressure of the water at the bottom mouth 821 of the pressure-relief pipe 822, then the surface 842 of the water within the pressure-relief pipe 822 will be above the pipe's bottom mouth 821, and air will remain trapped within the air pocket 840. Air from air pocket 840 enters the pressure-relief pipe 822 through upper mouth 843.
Instead of, or in addition to, the pressure relief pipe 822, a water pressure-relief pipe such as 611 in
When the air intake valve (816 in
Within electronics enclosure 813 are included (without limitation): computing devices and circuits 845; energy storage devices 846; and radio communications devices, transceivers, navigational devices, and the embodiment's control system 847.
The orientation of the embodiment's rudder 810, and the shaft 820 to which it is affixed, are adjusted and controlled by the rudder control mechanism 811 and a motor 848 therein, which, in turn, are controlled by the embodiment's control system 847.
The annular tube ballast chamber 805 contains a sealed space 849 that is filled with water. Other embodiments of this disclosure utilize different materials, and/or different relative locations, to supplement the ballast, and/or to adjust the natural frequencies, of those embodiments.
In some embodiments of this disclosure, the tube ballast chamber 849 contains perforations in its walls 805, especially at uppermost and lowermost portions (e.g. near seam 830 and near mouth 804), to facilitate the flooding of the chamber during initial deployment. Said perforations can allow air trapped inside the tube ballast chamber to exit (e.g. from perforations at an uppermost portion of the chamber), and allow water to flood into the chamber (e.g. from perforations at a lowermost portion of the chamber). Similar perforations can be provided in all embodiments of this disclosure that utilize a water ballast.
An embodiment similar to the one illustrated in
When air intake valve 816 is open, the suction created by a Venturi effect associated with the movement of water through constricting pipe 833C draws atmospheric air in through the air intake valve, and through the connected air intake pipe 844, after which a portion of the air passes through aperture 850 and into the stream of water flowing upward through conical tubular segment 833C. Air so drawn into the interior of the embodiment's hollow flotation module 802 will be trapped therein until and unless the pressure of that trapped air exceeds the level needed to overcome the hydrostatic pressure at the bottom mouth of the pressure-relief pipe (822 in
Note that in this embodiment, there is little or no “permanent buoyancy” provided, i.e. there are no large hermetically sealed volumes whose average density is lower than that of water. Instead, the buoyancy of the embodiment is provided by a pocket of air 840 inside the hollow flotation module 802. In other words, the average internal water level 838 tends to be vertically lower than the average external water level 801.
The altered embodiment configuration illustrated in
In other words, with respect to the embodiment configuration illustrated in
The embodiment 900 floats adjacent to a surface 901 of a body of water. The embodiment 900 comprises a buoyant, and approximately spherical, buoy 902 that floats at the surface 901 of a body of water, and a depending hollow inertial water tube 903, an upper portion 904 of which is tapered and approximately frustoconical. As the embodiment moves up and down in response to passing waves, water within the depending tube 903-904 tends to move up and down relative to the embodiment and not in phase with the embodiment, due in part to excitation by the tapered upper portion 904 of water tube 903. As water within the inertial water tube 903-904 moves up and down relative to the embodiment, water tends to enter and exit the inertial water tube, through a lower mouth 905 at a lower end of the inertial water tube 903, in an oscillating fashion though with a net upward water transport. Moreover, as water within the inertial water tube 903-904 moves up and down relative to the embodiment, water from within the inertial water tube is periodically ejected from an upper mouth (not visible) of the inertial water tube and deposited within the hollow interior of the embodiment's buoy 902, at an average rate of ejection corresponding to the net upward water transport.
As water is deposited within the buoy 902, air therein is compressed. When the volume, height, and/or level of the water within the buoy 902 is sufficient, and/or the pressure of the air trapped within the buoy 902 is sufficient, the pressure of the water within a bottom part and/or portion of the buoy's hollow interior can reach and/or surpass a threshold pressure, and water from within the buoy 902 will be forced out of the buoy 902 through an aperture, mouth, conduit, and/or portal 906. In the embodiment illustrated in
A water turbine (not visible) adjacent to the effluent aperture, and/or fully or partially within the channel defined by effluent pipe 907, is caused to rotate by the outflow of water through the respective effluent aperture 906 and/or effluent pipe 907. The water turbine is operatively connected to a generator (not visible), and outflowing-water-driven rotations of the water turbine cause the generator to generate electrical power.
In this manner, the pumping action of the embodiment creates a pressurized reservoir or accumulator within the buoy (upper hull enclosure) of the embodiment, which is drained in a relatively constant fashion to supply power to a turbine.
A portion of the electrical power generated by the embodiment's generator (not visible) may be used to energize radio communications equipment and/or circuits (not shown), including, but not limited to, phased array antennas. A portion of the electrical power generated by the embodiment's generator may be used to energize computing circuits (not shown) that perform, execute, and/or complete, computational tasks received by the embodiment through encoded radio transmissions, and/or by other means. A portion of the electrical power generated by the embodiment's generator may be used to energize propulsion devices (not shown) that may propel the embodiment in desired directions, and/or to desired locations.
An actuated valve 908 positioned at an upper portion of the buoy 902 can release air from within the buoy 902 so as to reduce the pressure therein. The valve 908 may be actuated directly in response to a sufficient pressure of the air within the buoy 902 being reached or exceeded, and/or it may be activated by the embodiment's electronic or fluidic control system (not shown) (i.e. the valve may be controlled as the result of analog or digital operations performed by fluidic logic gates and/or fluidic amplifiers).
A pressure relief pipe 909 ejects water from within the buoy 902 when the volume, height, level, and/or head pressure of that water, combined with the pressure of the air adjacent to that water, imparts to the water sufficient pressure to reach, exceed, and/or overcome the height of the upper mouth and/or aperture 910 of the pressure relief pipe 909.
An actuated valve 911 positioned at a lower portion of the buoy 902 can release water from the interior of the buoy so as to reduce the volume, height, level, and/or pressure of the air and/or water therein. The valve 911 may be actuated directly in response to a sufficient pressure of the water within the buoy 902 being reached and/or exceeded, and/or it may be activated by the embodiment's control system (not shown).
Pressure-relief pipe 909 has an upper mouth and/or aperture 910 through which water flows out from the interior of the buoy 902 to the outside of the embodiment if and when the pressure of that water is sufficient to lift the water past the upper aperture 910.
Actuated pressure-relief valve 908 has an upper aperture 912 through which air flows out from the interior of the buoy 902 to the atmosphere outside the embodiment when activated by, and/or in response to, the air pressure within the buoy 902 reaching and/or exceeding a specific threshold pressure, a threshold pressure dynamically determined by the embodiment's control system (not shown), and/or by the embodiment's control system for another reason, such as to adjust the level, volume, and/or mass of the water within the buoy 902, and the inertia therein, thereby adjusting the embodiment's waterline and waterplane area, which in turn tends to adjust and/or alter the sensitivity of the embodiment to the ambient wave energy.
Water within the buoy 902 flows out through effluent pipe 907 and/or effluent mouth 906 thereby causing a water turbine therein to rotate, and causing an operatively connected (not visible) generator to generate electrical power.
Actuated pressure-relief valve 911 has a lower aperture 913 through which water flows out from the interior of the buoy 902 to the body of water (901 in
Water moving up and down within inertial water tube 903 is periodically ejected from the tube's upper mouth 914 inside the buoy 902 and is thereafter deposited within the interior of the buoy 902. The constricting portion 904 of the inertial water tube tends to impart a pressure to and excite the water in the interior of the constricting portion when the embodiment is moving downwardly, and amplify the speed and momentum of the water rising up from the approximately cylindrical portion 903 of the inertial water tube, and thereby tends to cause the water ejected from the upper mouth 914 of the inertial water tube to achieve a height and/or head higher than the mean waterline of the embodiment with respect to the surface (901 in
As the embodiment 900 moves up and down in response to waves moving across the surface 901 of the body of water on which the embodiment floats, water 915 within the embodiment's inertial water tube 903, with an upper surface 916, tends to move 917 up and down relative to the tube's upper mouth 914, and it tends to move 918 up and down relative to the tube's lower mouth 905, with a net or average upward movement.
The interior of constricting portion 904 of inertial water tube 903 constitutes an interior wall defining a liquid pressurizing surface that can impinge upon and increase the pressure of water inside the tube (adjacent to that wall) when the embodiment moves downwardly relative to the water inside the water tube. The constricting portion 904 of inertial water tube 903 excites the water inside the inertial water tube, causing it to oscillate. Periodically, due in part to increases in pressure created by the constricting portion 904 and/or due to the oscillation of the water inside the tube excited by the constricting portion 904, a portion of the water within the inertial water tube rises above the inertial water tube's upper mouth 914 and is ejected 919 from the tube after which it falls into the hollow chamber 921 and/or interior within the buoy 902, and is thereby added to a reservoir and/or pool 920 of water within the hollow interior of the buoy 902. As water is added to the reservoir 920 the volume of the air 921 trapped within the buoy 902 is reduced, thereby compressing that air, and the pressure of that air 921 is increased. If the height, level, and/or upper surface 922 of the reservoir of water 920 within the buoy 902 rises to a height that exceeds the height of the tube's 903 upper mouth 914, then water from the water reservoir 920 will flow back into the tube 903 and be added to the water 915 therein until the upper surface 922 of the water reservoir is no greater than that of the tube's upper mouth 914. Although this embodiment does not have a feature that laterally diverts the water ejected from tube 903, the pitching and rolling motions of the embodiment can cause the water ejected from tube 903 to nonetheless fall into the reservoir of water 920 rather than to fall straight back down into the inertial water tube 903 and thereby rejoin the water 915 from which it was briefly separated.
The combination of the height, level 922, and/or head pressure of the water 920, and the pressure of the air 921, trapped within the buoy 902 tends to propel water from the water reservoir 920 through effluent pipe or conduit 907 where the flowing water engages and tends to rotate the water turbine 923, thereby energizing the generator 924. After flowing and/or passing through the water turbine 923, the water flows through effluent aperture 906, and thereby flows 925 back into the body of water 901 from which it was captured, and on which the embodiment floats.
Water from the reservoir 920 enters pressure-relief pipe 909 through its lower mouth 926. And if and when the pressure of the water within the water reservoir 920 is sufficient to force water high enough up and through pressure-relief pipe 909 such that it reaches and/or exceeds a the height of the pressure-relief pipe's upper mouth 910, then water from the buoy's reservoir 920 will flow out of, and/or exit, the interior of the embodiment through that upper mouth 910, thereby tending to reduce the pressure of both the water 920 and the air 921 within the buoy's hollow interior. During operation of the embodiment, the water surface inside pressure-relief pipe 909 will tend to be some distance above the upper surface of the water in water reservoir 920, due to the elevated pressure of the air 921 above that water, i.e., the combined water and air pressures will tend to exceed the atmospheric pressure of the air in the upper portion of the pressure-relief pipe 909.
A nominal deployment of the embodiment 930 positions it adjacent to an upper surface 931 of a body of water over which waves travel, at least periodically and/or occasionally. The embodiment 930 comprises an approximately spherical buoyant portion 932 and an approximately cylindrical depending tubular portion, i.e., an inertial water tube, 933 that possesses a lower 934 mouth through which water may freely enter and freely exit the interior of the inertial water tube 933, and an upper mouth (not visible) through which water may freely exit the interior of the inertial water tube.
As the embodiment 930 moves up and down in response to passing waves, water within the inertial water tube 933 tends to move up and down, at times moving out of phase with the wave-responsive movements of the embodiment 930. Periodically and/or occasionally water rises within the inertial water tube 933 to a sufficient height, and/or with sufficient speed, to escape the upper mouth of the inertial water tube 933 and thereafter be trapped, and/or deposited, within the interior of the hollow buoy 932, i.e. into the embodiment's water reservoir or internal water tank. As water is added to the reservoir of water within the buoy 932, the volume of the air trapped within the buoy is reduced and its pressure is thereby increased.
A portion of the pressurized water within the buoy tends to flow back to the body of water 931 from which it was captured through an effluent port, aperture, pipe, portal, and/or channel 935. As water from within the buoy 932 flows out through effluent portal 935 it engages and tends to cause to rotate a water turbine positioned therein and/or adjacent thereto. In response to rotations of the water turbine, a generator, operatively connected to the water turbine by a shaft, is energized, e.g., through rotations of the generator's rotor, thereby generating electrical power. In similar embodiments, the water turbines impart rotational power to hydraulic rams, accumulators, and motors and the water turbines are energized directly or indirectly by the hydraulic motors. In other similar embodiments, other power takeoffs are utilized.
The scope of the current disclosure is not limited to the type and/or number of power takeoff mechanisms utilized. In similar embodiments, no electricity is generated, but rather, high-pressure water is passed over, through, and/or into filtration and/or adsorption substances and/or mats configured to remove valuable elements and/or compounds from the water, e.g. an adsorption substance designed to extract dissolved lithium from the water.
As water leaves the effluent portal 935 the flow of at least a portion of that water, or of water moved by that water, tends to be obstructed by a surface 936 which tends to deflect at least a portion of that flow away from the embodiment along an approximately radial, lateral, horizontal, and/or flow-normal vector, thereby generating lateral thrust that tends to propel the embodiment in a direction opposite that of the deflected flow and across the surface of the body of water on which the embodiment floats.
An actuated valve 937 positioned at an upper portion of the buoy 932 can release air from the interior of the buoy 932 so as to reduce the pressure of the air and water within the buoy. The valve 937 may be actuated directly (e.g. passively) in response to a sufficient pressure of the air within the buoy 932 being reached and/or exceeded, and/or it may be activated (e.g. actively) by the embodiment's control system (not shown), e.g. when electrical sensors detect a threshold pressure within the embodiment.
A pressure relief pipe 938 ejects water from the interior of the buoy 932 when the volume, height, level, and/or head pressure of that water, combined with the pressure of the air adjacent to that water, imparts to that water sufficient pressure to reach, exceed, and/or overcome the height of the upper mouth and/or aperture of the pressure relief pipe 938.
An actuated valve 939 positioned at a lower portion of the buoy 932 can release water from the interior of the buoy 932 so as to reduce the pressure of the air and water therein. The valve 939 may be actuated directly in response to a sufficient pressure of the water within the buoy 932 being reached and/or exceeded, and/or it may be activated by the embodiment's control system (not shown).
Water flowing 940 over, and/or through, the embodiment's water turbine (not visible) and back to the body of water 931 on which the embodiment floats is deflected by a surface 936 of a structural element 941 attached to the embodiment's tube 933 thereby generating a lateral thrust useful in propelling the embodiment across the surface 931 of the body of water on which the embodiment floats.
The embodiment's 930 inertial water tube 933 is hollow, with upper (not visible due to a lateral bend in the upper portion of the inertial water tube) and lower 942 mouths, and tends to contain water within at least a portion of its internal channel.
The buoy portion 932 of embodiment 930 is comprised, at least in part, of a flexible cloth, sheet, panel, covering, material, and/or barrier that is held in an approximately spherical shape by an internal pressure of air and water that pushes outward against the inner surface(s) of the flexible material. The nominal spherical shape of the buoy 932 is preserved, e.g., in the case of a reduction in the buoy's internal pressure, by a set of vertical circumferential ribs, struts, tubes, pipes, beams, and/or rods, e.g., 943, that span the buoy adjacent to an inner surface of its outer flexible covering 932, radiating outward from an uppermost point 944 to a corresponding lowermost point (not visible) and arranged in a pattern similar to the arrangement of lines of longitude on a globe. One or more horizontal circumferential ribs, struts, tubes, pipes, beams, and/or rods, e.g., 945, that span the buoy adjacent to an inner surface of its outer flexible covering 932, radiating about the embodiment's nominally flow-normal and/or vertical longitudinal axis and arranged in a pattern similar to the arrangement of lines of latitude on a globe.
As the embodiment 930 moves up and down in response to waves passing across the surface 931 of the body of water 931 on which the embodiment floats, water 942 within the embodiment's inertial water tube 933 tends to move up and down, at times out of phase with, and/or with a greater amplitude than, the vertical movements of the embodiment. As water 942 within the inertial water tube 933 moves up and down, water enters and exits 946 through the inertial water tube's lower mouth 934. Likewise, the surface 947 of the water within the inertial water tube 933 moves 948 up and down, periodically moving high enough that a portion thereof is ejected 949 from the upper mouth 950 of the tube. A portion of the water ejected 949 from the upper mouth 950 of the inertial water tube falls to the bottom of the inner chamber and/or hollow of the buoy's 932 interior thereby adding to the volume of water 951 in a pool and/or reservoir of water in a lower portion of the buoy's interior, and likewise raising the level and/or upper surface 952 of that water reservoir 951. As the volume of water within the embodiment's water reservoir 951 is increased, the volume of air 953 trapped, and/or contained, within an upper portion of the buoy's interior is decreased, and its pressure is increased.
At least in part due to an increase in the pressure of the air and water within the buoy's 932 water reservoir 951, a portion of the water within the buoy's reservoir 951 tends to flow out of the buoy and back to the body of water 931 from which it was originally captured through effluent pipe 935. As water flows through effluent pipe 935 it flows over and/or through a water turbine 954 therein. As water flows through water turbine 954, the turbine tends to rotate, which causes the attached shaft 955 to rotate, which, in turn, causes the rotor of generator 956 to rotate, thereby causing generator 956 to generate electrical power.
Water flowing out of effluent pipe 935 tends to be obstructed and/or diverted by surface 936 which tends to cause that flow to move away from the embodiment 930 in a horizontal direction radially and laterally oriented away from the embodiment's nominal flow-normal and/or vertical longitudinal axis. The diverted flow of water tends to impart to the embodiment thrust in a direction opposite the flow's direction and radially oriented away from the embodiment's nominal flow-normal vertical longitudinal axis in the opposite direction, thereby tending to propel the embodiment across the surface 931 of the body of water on which the embodiment floats.
When the pressure of the water within the buoy's water reservoir 951 exceeds a threshold pressure, that pressure becomes sufficient to cause water entering the lower mouth and/or aperture 957 of pressure-relief pipe 938 to flow up to, and flow 958 out of, the upper mouth and/or aperture 959 of that pressure-relief pipe, thereby reducing and/or relieving the “excess” water pressure.
Notice that a substantial portion of the narrowing, tapered, and/or constricting upper portion 960 of the embodiment's tube 933 is arched, tilted, slanted, and/or bent so that its axis of flow tends to not be coaxial with a straight, and nominally vertical, longitudinal axis, and/or axis of radial symmetry, of the inertial water tube 933. This bending of the upper portion of the tube 933 tends to cause water ejected 949 from the inertial water tube's upper mouth 950 to be projected laterally as well as vertically.
A similar embodiment lacks an effluent pipe 935, and instead has an aperture in the wall of the buoy 932, in which aperture, or adjacent to which aperture, a water turbine is positioned and energized by the flow of water through that aperture.
The embodiment 1000, when nominally deployed in a body of water, tends to float adjacent to an upper surface 1001 of the body of water. The embodiment comprises a buoy portion 1002 with an approximately ellipsoidal hull, and a plurality of hollow, approximately cylindrical inertial water tubes, e.g., 1003, of which are positioned about a lateral and/or horizontal periphery of the buoy 1002 and have relatively small flow-normal cross-sectional areas, and two, e.g., 1004, of which are positioned adjacent to the lateral and/or horizontal center of the buoy 1002 and have relatively large flow-normal cross-sectional areas. Although not obvious from the illustration in
Each of the eight inertial water tubes, e.g., 1003 and 1004, has a lower mouth, e.g., 1005 and 1006, respectively, through which water may enter and leave each respective inertial water tube without significant impediment, obstruction, and/or resistance.
The top 1007 of the buoy 1002 is curved in a manner that might be characterized as being consistent with that of a partially flattened ellipsoid. A portion 1008 of the top surface of the buoy is flat, and attached thereto is a water turbine compartment 1009, in which is positioned a water turbine (not visible) that is operatively connected to a generator 1010.
Also attached to a top portion 1007 of the buoy 1002 are two rigid sails 1011 and 1012. Each rigid sail is connected to a respective sail shaft 1013 and 1014. And, each sail shaft is operatively connected to a respective shaft-rotation mechanism 1015 and 1016, e.g., a stepper motor. Note that the rigid sails in
Each of the two wider and longer inertial water tubes, e.g., 1017, penetrates the lowermost hull 1002 of the embodiment's buoy at a position, e.g., 1018, near the buoy's bottom and/or point of maximal draft. Each of the six more narrow and shorter tubes, e.g., 1019, penetrates the lowermost hull 1002 of the embodiment's buoy at a position, e.g., 1020, approximately midway between the buoy's top 1007 and its bottom 1002.
The embodiment incorporates eight tubes oriented approximately vertically and each tube is hollow with a lower mouth, e.g., 1006, and an upper mouth (not visible). Six tubes 1003, 1019, and 1021-1024 have relatively small flow-normal cross-sectional areas. Two tubes 1004 and 1017 have relatively large flow-normal cross-sectional areas.
Water discharged from the embodiment's water turbine (not visible) is returned to the body of water on which the embodiment floats through effluent pipe 1025.
As the embodiment 1000 moves up and down in response to waves passing across the surface 1001 of the body of water on which the embodiment floats, water tends to move up and down within the embodiment's eight inertial water tubes, and be excited in its vertical oscillations by the constricting (pressurizing) surfaces or internal walls thereof. In the cross-sectional illustration of
As water 1026 within inertial water tube 1004 moves up and down, water is made to flow 1027 in and out of the tube through the tube's lower mouth 1006. The movement of water 1026 within the inertial water tube 1004 also causes the upper surface 1028 of that water to move 1029 up and down, occasionally causing a portion of that water to be ejected 1030 from the upper mouth 1031 of the inertial water tube 1004. There is a net upward transport of water up the tubes. The upper portion 1032 of inertial water tube 1004 is constricted and curved which tends to cause water rising through that upper portion 1032 of the inertial water tube to be accelerated and upon ejection to be directed laterally. After falling within the interior of the buoy, water ejected 1030 from inertial water tube 1004 joins, and increases the volume of, water pooled in a reservoir 1033 within the buoy 1002 thereby raising the level 1034 and/or surface of that water reservoir 1033. An increase in the volume of water within the embodiment's water reservoir 1033 results in a decrease in the volume of the air 1035 above the water reservoir, and trapped as an air pocket within the buoy's 1002 interior, thereby increasing the pressure of that air and providing a store of potential energy that enables water to be forced out of the reservoir of the embodiment, via a flow governor such as a turbine, at elevated pressure.
Similarly, as water 1036 within inertial water tube 1017 moves up and down water is made to flow 1037 in and out of the inertial water tube through the inertial water tube's lower mouth 1038. The movement of water 1036 within the inertial water tube 1017 also causes the upper surface 1039 of that water to move 1040 up and down, occasionally causing a portion of that water to be ejected 1041 from the upper mouth 1042 of the inertial water tube. The upper portion 1043 of inertial water tube 1017 is constricted and curved which tends to cause water rising through that upper portion 1043 of the inertial water tube to be accelerated and upon ejection to be directed laterally. After falling within the interior of the buoy, water ejected 1041 from inertial water tube 1017 joins, and increases the volume of, water pooled in a reservoir 1033, just as does water ejected 1030 from inertial water tube 1004 and water ejected from the embodiment's other six inertial water tubes, e.g., 1024.
The embodiment's narrower six inertial water tubes, e.g., 1022 and 1024, also possess upper portions, e.g., 1044 and 1045, respectively, that are constricted and curved.
When the pressure of the water in the embodiment's water reservoir 1033 is high enough, water rises up a turbine ingress pipe (not visible) and enters a water turbine compartment 1009 where it engages with, and tends to cause the rotation of, the embodiment's water turbine 1046, thereby causing the rotation of a turbine shaft which operatively connects the water turbine to the embodiment's generator 1010, thereby causing electrical energy to be produced. After passing through the water turbine 1046, the water that had risen through the turbine ingress pipe (not visible), then flows down through effluent pipe 1025 and therethrough flows 1047 back into the body of water 1001 on which the embodiment floats.
The sectional view illustrated in
The section plane of the illustration in
Because the embodiment's two sets of inertial water tubes, i.e., those of relatively larger and those of relatively smaller flow-normal cross-sectional areas, and of relatively longer and relatively shorter lengths, respectively, will tend to have different natural frequencies, each set of inertial water tubes will tend to eject water into the water reservoir 1033 within the buoy 1002 at optimal and/or maximal rates of flow in response to, and/or with respect to, wave conditions of differing energies, significant wave heights, and/or dominant wave periods.
As water 1051 within inertial water tube 1021 moves up and down that water tends to flow 1052 in and out of the lower mouth of the inertial water tube. The movement of water 1051 within the inertial water tube 1021 also causes the upper surface 1053 of that water to move up and down, occasionally causing a portion of that water to be ejected 1054 from the inertial water tube's upper mouth. The upper portion 1055 of inertial water tube 1021 is constricted and curved which tends to cause water rising through that upper portion of the inertial water tube to be accelerated and upon ejection to be directed laterally. After falling within the interior of the buoy, water ejected 1054 from inertial water tube 1021 joins, and increases the volume of, water pooled in a water reservoir 1033 within the buoy 1002, thereby raising the level 1034 and/or surface of that water reservoir.
Similarly, as water 1056 within inertial water tube 1023 moves up and down water tends to flow 1057 in and out of the inertial water tube through the inertial water tube's lower mouth. The movement of water 1056 within the inertial water tube 1023 also causes the upper surface 1058 of that water to move up and down, occasionally causing a portion of that water to be ejected 1059 from the inertial water tube's upper mouth. The upper portion 1060 of inertial water tube 1023 is constricted and curved which tends to cause water rising through that upper portion of the inertial water tube to be accelerated and upon ejection to be directed laterally. After falling within the interior of the buoy, water ejected 1059 from inertial water tube 1023 joins, and increases the volume of, water pooled in a water reservoir 1033 thereby raising the level 1034 and/or surface of that water reservoir.
The upper curved and constricted portions of the embodiment's inertial water tubes are visible within the hollow interior of the buoy 1002. Each inertial water tube tends to eject water periodically in response to wave motion at and/or against the embodiment. Pressurized water from within the embodiment's water reservoir 1033 rises through turbine ingress pipe 1049 after which it flows through the embodiment's water turbine (not visible). The discharge from the water turbine flows down through effluent pipe 1025 where it is deposited into the body of water on which the embodiment floats.
The embodiment 1100, after a nominal deployment and/or when positioned in a nominal operational configuration and a nominal operational environment, floats adjacent to an upper surface 1101 of a body of water over which waves at least occasionally pass. The embodiment possesses a buoy 1102-1104 comprised of three hull portions. A lower hull portion 1102 that is approximately ellipsoidal in shape. A middle hull portion 1103 that has the shape of a flattened ellipsoid. And, an upper portion 1104 which is approximately flat. Attached to the upper portion 1104 is a water turbine compartment 1105 and attached to that water turbine compartment is a generator 1106. Barely visible behind the water turbine compartment 1105 is a portion of an effluent pipe 1107 that carries away water discharged by the water turbine.
Depending from a lower portion 1102 of the buoy are two hollow tubes 1108 and 1109, each possessing a lower mouth 1110 and 1111, respectively. Providing structural stability to each tube 1108 and 1109 is a respective bracing panel 1112 and 1113. Protruding from a lower portion of the buoy hull 1102 is a water turbine pipe 1114 wherein is positioned a water turbine (160 in
Also protruding from a lower portion 1102 of the buoy hull is a water jet 1115 through which pressurized water from inside the buoy flows back to the outside and/or ambient water 1101 after first being accelerated by a nozzle 1116 positioned at an end of the jet 1115. The water jet 1115 can be rotated about an approximately vertical axis so as to generate thrust in and/or with any radial orientation and/or direction about the embodiment. The passage of water through the water jet 1115, and/or the rate at which water flows out from the water jet, is controlled by a valve that is actuated and/or controlled by the embodiment's control system (not shown).
Arrayed about the periphery of the buoy 1102-1104, and above the surface 1101 of the body of water on which the embodiment floats, are eight additional water jets, e.g., 1117, the orientations of each of which is fixed, and the passage of water through each of which, and/or the rate at which water flows out of each of which, is controlled by a respective valve that is actuated and/or controlled by the embodiment's control system (not shown). The thrust produced by the outflow of water from each peripheral water jet, e.g., 1117, tends to impart a radial and/or lateral thrust to the embodiment that tends to be normal to a vertical axis of the embodiment and/or approximately parallel to the resting surface 1101 of the body of water on which the embodiment floats and tends to push the embodiment across the surface 1101 of the body of water in a direction from each respective water jet that tends to pass through the center of the buoy, i.e., through the buoy's vertical longitudinal axis of radial symmetry.
Pressurized water within the embodiment's buoy 1102 flows 1128 through a lower mouth and/or aperture 1118 of water turbine pipe 1114 and a water turbine (not visible) therein and returns to the body of water 1101 from which it was originally captured.
In the embodiment configuration illustrated in
Distributed about the periphery of the embodiment's buoy 1102 are eight peripheral water jets, e.g., 1117, and 1121-1124. The embodiment's peripheral water jets are fixed in position and orientation so as to always project water (when their respective flow-control valves are opened by the embodiment's control system) in a direction and/or along a vector that is substantially parallel to the resting surface 1101 of the body of water on which the embodiment 1100 floats, and is aligned in radial fashion outward from a vertical central longitudinal axis of the embodiment, and tending to generate thrust in the opposite direction.
In the embodiment configuration illustrated in
After pressurized water from within the embodiment's buoy 1102 flows up to and through the water turbine (not visible) within the water turbine compartment 1105, thereby causing the operatively connected generator 1106 to generate electrical power, it then flows out and down through effluent pipe 1107, passing out of the pipe through the pipe's lower mouth and/or aperture 1126 and flowing 1127 back into the body of water 1101 on which the embodiment floats.
Water turbine 1160 is positioned within water turbine pipe 1114 and is made to rotate when water flows out of the embodiment's low-energy water reservoir and into the body of water 1101 on which the embodiment floats. Rotations of the water turbine 1160 cause an operatively connected generator to generate electrical power.
The embodiment 1100 incorporates two hollow inertial water tubes 1108 and 1109, each of which has a bottom portion that is approximately cylindrical. However, the upper portion of each inertial water tube penetrates the bottom hull 1102 of the buoy after which each tube narrows and bends toward the lateral and/or horizontal center of the buoy. The bottom approximately half of each inertial water tube is removed above what is the nominal height of an internal reservoir of water that tends to be positioned in a lower portion 1131 of the hollow interior of the embodiment's buoy 1102.
Water ejected 1151 from either tube with an abundance of speed will tend to follow the curving upper wall of the tube and thereafter be propelled laterally toward a central raised second water reservoir 1132 into which a portion of that water will tend to fall and join the water 1133 already contained within said raised reservoir 1132.
By contrast, water ejected from either inertial water tube with a paucity of speed, and/or with very little remaining kinetic energy, will tend to fall through and/or out of the missing bottom half of the curved upper portion of each respective inertial water tube. Such low-energy water will tend to fall into the bottom water reservoir 1131.
The use of a “split” curved upper portion within each inertial water tube allows the embodiment to collect water ejected with a relatively large amount of energy in a water reservoir 1132 that is raised and/or positioned so as preserve a substantial portion of that water's energy as gravitational potential energy and/or head pressure. The split curved upper portion within each inertial water tube also allows the embodiment to collect water ejected with a relatively small amount of energy in a substantially lower water reservoir 1131 positioned so as preserve in the ejected water a significantly lower amount of gravitational potential energy and/or head pressure.
The alternative to using inertial water tubes with split curved upper portions is to use inertial water tubes with integral lateral and/or outer tube walls and with flow-normal mouths. The lengths, orientations, and designs of such “one-mouth” inertial water tubes will tend to eject water possessing and/or manifesting at least a requisite level of energy (e.g., kinetic energy, speed, momentum, etc.). Water rising within the respective inertial water tubes that possesses less energy will not be ejected and will not add to the volume of water within the embodiment's water reservoir. Water rising with a level of energy (e.g., kinetic energy, speed, momentum, etc.) that is significantly greater than the level required to achieve ejection will add to, and/or increase, the volume of water within the embodiment's water reservoir, but the surplus energy available at the time of its ejection will be lost as that water falls into the water reservoir thereby sacrificing much of its available gravitational potential energy.
An embodiment of the present disclosure may include, incorporate, and/or utilize, any number of water reservoirs, positioned at different relative heights, and/or at different heights above the surface of the water on which the embodiment floats, and may utilize any type, design, and/or configuration of inertial water tube to direct ejected water of differing energies into the water reservoir that causes the least amount of gravitational potential energy to be wasted.
Water 1131 trapped, stored, captured, and/or cached, within the lower low-energy water reservoir 1131 flows out through a hole, pipe, aperture, and/or portal (1114 in
Water 1133 within the higher, raised, and/or elevated, high-energy water reservoir 1132 flows into a mouth of a water turbine ingress pipe 1135 after which it flows upward and engages a second water turbine (not visible) positioned within the embodiment's water turbine compartment (1105 in
By permitting both high- and low-energy water to be captured within separate water reservoirs within its buoy 1102, the embodiment 1100 increases the volume of water that it collects (e.g., by collecting low-energy water that would have otherwise failed to be ejected) as well as preserving and converting to electrical power both the greater and lesser potential energies of the captured waters. Those skilled in the art will understand that there are a large number of configurations that enable the collection of water in two or more water reservoirs each having different water surface levels, all of which configurations are included within the scope of this disclosure.
Outside and/or below the lower hull 1102 of the embodiment's buoy, each of the embodiment's inertial water tubes, e.g., 1108, is approximately cylindrical. However, after entering and/or passing into the interior of the buoy, each inertial water tube narrows, which tends to accelerate water rising through the inertial water tube, and each inertial water tube bends toward the other inertial water tube and/or toward the middle of the buoy. For instance, outer cylindrical tube 1108 bends and narrows 1129 within the buoy's interior. Above the nominal surface 1131 of the low-energy water reservoir, and/or above the nominal waterline 1137 of the low-energy water reservoir 1131 against the upper portion 1129 of the inertial water tube, the upper half 1138 of that inertial water tube is present, but the lower half 1139 of that inertial water tube is removed and/or missing. Thus, high-speed, high-energy water rising through the tube 1129 will be guided by the curving upper half of the tube and a portion of that water may fall into the high-energy water reservoir 1132. And, low-speed, low-energy water rising through the inertial water tube 1129 will be able to “spill out of” the missing lower half 1139 of the upper portion of the inertial water tube, and will tend to fall into the low-energy water reservoir 1131.
The raised, high-energy water reservoir 1132 is supported, at least in part, by vertical struts, e.g., 1140.
Water from the high-energy water reservoir 1132 flows up through water turbine ingress pipe 1135 and imparts a portion of its energy to the embodiment's high-energy and/or second water turbine (not visible) and it then falls through effluent pipe 1107 through which it flows back into the water outside the embodiment. Water from the low-energy reservoir 1131 flows out into the water outside the embodiment through water turbine pipe and/or portal 1114, imparting a portion of its energy to the embodiment's low-energy and/or first water turbine therein, which imparts rotational kinetic energy to its attached shaft 1141, which, in turn, causes the operatively connected generator 1134 to generate electrical power.
As the embodiment 1100 moves up and down in response to waves passing at the surface 1101 of the body of water on which the embodiment floats, water 1142 and 1143 within each of the embodiment's respective two inertial water tubes 1108 and 1109 tends to move up and down, causing water to move 1144 and 1145, respectively, in and out of each inertial water tube's respective lower mouth 1110 and 1111, and causing the respective upper surfaces 1146 and 1147 of that water to move 1148 and 1149 up and down. As the upper surfaces 1146 and 1147 of the water 1142 and 1143, respectively, in each inertial water tube, moves up and down, a portion of that water tends to occasionally be ejected, e.g., 1150 and 1151, from an upper end of each inertial water tube. Because of the open channel created at the bottom of the upper portion of each inertial water tube, through the removal of the bottom halves of those respective uppermost inertial water tube portions, e.g., 1138, water can exit the end of each inertial water tube with a range of speeds, and can collide with the interior of the buoy 1102 at a range of distances and heights from each inertial water tube.
Water ejected from each inertial water tube, e.g. 1129, with a relatively small amount of energy and/or speed may exit its respective inertial water tube at a relatively low height, and/or with a relatively low speed, e.g., 1150, thereby tending to fall only a short distance from the inertial water tube, and likely falling into the low-energy water reservoir 1131. On the other hand, water ejected from each inertial water tube, e.g. 1129, with a relatively great amount of energy and/or speed may exit its respective inertial water tube at a high elevation and with significant speed, e.g., 1151, and a portion of that water will likely fall into the raised, high-energy water reservoir 1132, thereby preserving at least a portion of the relatively high energy of that ejected water as additional gravitational potential energy and/or head pressure, i.e., with respect to the amount of gravitational potential energy and/or head pressure preserved by the low-energy reservoir 1131.
Water 1133 contained, trapped, stored, and/or cached, within the high-energy water reservoir 1132 may enter a water turbine ingress pipe (not visible) and then pass through a second water turbine 1152, thereby causing an operatively connected generator 1106 to generate electrical power, and thereafter flowing through effluent pipe 1107 so as to return to the body of water 1101 outside the embodiment.
When the flow valve controlling the flow of water through a peripheral water jet, e.g., 1117, is opened by the embodiment's control system (not shown) a portion of the pressurized water in the embodiment's low-energy water reservoir 1131 enters 1153 the water jet and subsequently flows through the water jet's nozzle and is accelerated 1154, generating thrust in the process. When the flow valve controlling the flow of water through a peripheral water jet, e.g., 1124, is closed by the embodiment's control system (not shown), water is unable to flow through and/or out of the water jet's nozzle. When the embodiment's control system opens a water jet's flow valve to an intermediate degree, the amount and/or rate of water flow from the jet can be adjusted to create an intermediate degree of thrust.
As water is added to either or both of the high- 1132 and/or low-energy 1131 water reservoirs, the air 1155 trapped within the buoy's 1102/1103 interior is compressed thereby increasing its pressure. The raised pressure of that air 1155 adds to the force propelling water into both the low-energy first water turbine (not visible, inside the water turbine pipe 1114) and the high-energy second water turbine (not visible, inside the water turbine compartment 1105).
The cutaway 1156, removed, and/or missing lower half of the inertial water tube 1109 is visible in the illustration of
Water captured in the raised, high-energy water reservoir 1132, at least in part in response to the raised air pressure within the buoy 1102/1103, enters a lower mouth 1157 of water turbine ingress pipe 1135 after which it passes to and through the water turbine 1152 and imparts energy to it. After flowing through water turbine 1152, the water then flows through effluent pipe 1107 down into the body of water 1101 on which the embodiment 1100 floats.
This embodiment is comprised of two primary components, a nominally buoyant (i.e. prone to floating in a fluid) oblate spheroid structure 1200 and three (other embodiments may have more or less) hollow inertial water tubes, e.g. 1201. Flotation collar 1207 (also called buoyancy band 1207) imparts additional buoyancy to the structure and may be comprised of foam, encapsulated air (e.g. encapsulated in hollow steel structures), or any substance and/or structural element less dense than water.
Waves present in body of water 1206 impart a vertical force onto upper hull enclosure or flotation module 1200, causing it to oscillate and/or perturbate in a motion that is approximately perpendicular to the surface of body of water 1206. As 1206 oscillates, water from below inertial water tubes, e.g. 1201, enters and exits (1208) through open tube bottoms, e.g. 1202. The water preferentially moves upward, resulting in a net flow through the inertial water tubes, e.g. 1201, towards the structure 1200. The frustoconical bell shape of inertial water tubes, e.g. 1201, which has decreasing transverse and/or flow-normal cross-sectional area relative to an upward direction of water movement, helps to excite the oscillatory net flow in inertial water tubes, e.g. 1201. If the upward movement of the fluid in one or more of the inertial water tubes, e.g. 1201, is of sufficient amplitude, a portion of the fluid will pass above the surface 1206 of the body of water, through the curved portions of the inertial water tubes, e.g. 1203, and will enter the hollow structure and/or flotation module of 1200 where the inertial water tubes, e.g. 1203, enter that structure (e.g. at penetration location 1204).
The addition of water from the body of water 1206 to the interior chamber of the hollow flotation module 1200 will reduce the volume of, and/or compress, the air in that chamber, thereby increasing the pressure of that air. This additional air pressure allows the water inside the hollow flotation module to be released to the outside of the hollow flotation module with positive flow rate and pressure, thus providing power. This power may be used to drive a turbine, pump, motor, or can be sprayed in such a way as to provide thrust. The air can also be sprayed into the atmosphere (e.g. using aerosolization nozzles) to provide cloud nucleation sites thereby tending to increase cloud albedo. The following figures will indicate that the particular embodiment shown uses a turbine that is used to harness power from the embodiment's pressurized water and to generate electricity and also has a method for providing thrust to the embodiment.
Computer chamber 1209 contains electronics which may include power conditioning equipment, computers for controlling the functions of the embodiment, or networks of computers used for high performance computation, including processing computational tasks or instructions received by various remote communications means (such as radio signals). Computer chamber 1209 is nominally waterproof and/or hermetically sealed. Phased array antenna 1210 is used to wirelessly communicate (e.g. transmit and/or receive data and/or signals) with satellites, drones, airplanes, spaceplanes, helicopters, kites, balloons, blimps, boats, terrestrial/ocean based antennas through any of the various bands in the electromagnetic spectrum, but preferentially in the frequency ranges defined as radio, microwave, infrared, and/or visible light. Phased array antenna 1210 can contain additional radio antennas, LEDs, and/or any other means of producing electromagnetic radiation in the aforementioned frequency ranges.
Water contained in hollow flotation module 1200 which is pressurized, at least in part, by compressed air, is forced to exit (1212) the interior of the hollow flotation module 1200 through water turbine 1211. If the compressed air exceeds a pre-determined threshold pressure, valve 1213 may actively open through a command from the embodiment's control system housed in 1209 or it may passively open in direct response to the excessive pressure. This action would allow pressurized air to escape until a desired and/or nominal pressure was restored to the interior of the hollow flotation module 1200.
Hollow inertial water tubes, e.g. 1201, are rigidly linked together by coupling 1215 proximate to their bottom ends and/or near their lower tube openings and/or mouths, e.g. 1202.
The surface 1206 of water outside the embodiment, as well as the oscillating surface 1227 of the water within inertial water tube 1201 are illustrated in
The surface 1218 of water accumulated within buoy 1200 is shown to be lower than that of the external body of water 1206. This configuration provides additional buoyancy to the embodiment, in addition to or instead of that provided by buoyancy band 1207. (In some embodiments, enough “permanent buoyancy” such as buoyancy band 1207 can be provided such that interior waterline 1218 will nominally be at approximately the same vertical level as mean external-body-of-water waterline 1206, or above mean external-body-of-water waterline 1206.) Water accumulated, stored, captured, cached, and/or trapped, within the embodiment's water reservoir 1218 will cause the gas (air, nitrogen, argon, etc.) within an upper portion of the interior chamber 1222 of the hollow flotation module to increase in pressure as more water enters the chamber and is added to the water reservoir. The pressurized air within the interior chamber 1222 of the hollow flotation module exerts a force on the water 1218, allowing and/or compelling it to pass through water turbine 1211 and back into the body of water 1206 on which the embodiment floats. The water turbine 1211 spins and causes an attached turbine shaft 1216 to rotate. This rotation energizes generator 1219, thereby causing the generator to generate electricity. Water turbine 1211 spins within an aperture and/or hole within a lower portion of the hollow flotation module's wall. Similarly and alternately, a magnetohydrodynamic generator can be employed in place of the water turbine 1211 and generator 1219, to generate electrical power from a flow of water 1212 forced out of the interior chamber 1222.
Generator 1219 is housed in a chamber 1217 that is watertight with respect to its lateral and upper walls, and which is filled with air, nitrogen, argon, or some other gas. The water within the embodiment's water reservoir 1218 is excluded from an upper portion of the generator chamber 1217 due to the trapped bubble of gas therein, and the water therefore forms a surface 1225 within the generator chamber at a position and/or level below the generator. The generator is thus surrounded by air and is protected from damage that might result from its immersion in water. Through the use of the air-filled generator chamber, a less-expensive generator (e.g., one not designed for submersion in water) may be used thereby reducing the cost of the embodiment.
The airtight chamber 1217 is supported by a spar 1220, which also contains power transmission cables which bring power up from the generator to equipment and computers contained in computer chamber 1209. This electricity also powers the phased array antenna 1210.
Valve 1223 can be actuated on command or passively, so as to allow and/or cause pressurized water to be ejected 1224 into the body of water 1206 on which the embodiment floats. Such an ejection of water from the water reservoir 1218 tends to lower the pressure and level 1218 of the water within the interior chamber 1222 of the hollow flotation module. The reaction force from the ejection 1224 of water from valve 1223 tends to impart an acceleration to the embodiment causing it to move laterally across the surface 1206 of the body of water on which the embodiment floats.
Note that some embodiments will include and/or incorporate a cylindrical tube at the bottom of each of the angled inertial water tubes, e.g., 1201, such that an upper portion of each of the inertial water tubes has a decreasing transverse and/or flow-normal cross-sectional area relative to water movement in an upward direction within the inertial water tubes, whereas a bottom portion of each of the inertial water tubes has a nondecreasing transverse and/or flow-normal cross-sectional area relative to water movement in an upward direction within the inertial water tubes.
Individual antenna nodes (e.g., individual dipole antennas) of phased array antenna 1210 are resolved in this figure. In addition to facilitating the transmission and receipt of radio signals, each antenna node also includes, incorporates, and/or utilizes, one or more LEDs 1229 attached and/or connected to an upper end of each antenna node. The LEDs attached to the antenna nodes can be used individually or in harmony and/or synchrony for signaling, communication, data transmission, etc. The array of LEDs may also be used as or as part of an optical phased array whose coordinated flashing promotes the propagation of light signals preferentially in a chosen or dynamically computed direction, e.g. toward a moving satellite or aircraft.
Embodiment 1300 includes an approximately spherical flotation module 1302 whose skin or outer surface is substantially impervious to water and gases. Depending from spherical flotation module 1302 is a hollow inertial water tube 1303/1304 whose top portion 1303 is tapered and/or constricted, and whose bottom portion 1304 is approximately cylindrical. The bottommost portion of bottom inertial water tube portion 1304 is open to the body of water forming an approximately circular lower mouth 1305 through which water can pass upwardly and downwardly, in and out of the interior of the inertial water tube 1304. The interior of hollow inertial water tube 1303/1304 is therefore open to the body of water at 1305, and is also open to the hollow interior of spherical flotation module 1302, except that a first one-way valve (not shown) is located in inertial water tube neck 1337 and tends to permit the flow of fluid from the inertial water tube into the interior of the spherical flotation module 1302, and tends to obstruct the flow of fluid from the interior of spherical flotation module 1302 into the inertial water tube 1303/1304.
The first one-way valve, positioned in neck 1337, is configured to allow fluid to pass preferentially in an upward direction, i.e., from the interior of inertial water tube 1303/1304 into the interior hollow cavity of spherical flotation module 1302. In some embodiments, the one-way valve allows approximately no fluid to pass in the reverse direction (from the interior of structure 1302 into the interior of inertial water tube 1303/1304). In some embodiments, the valve allows some fluid to pass in this reverse direction, although the valve is preferential to fluid passage in the upward direction.
Propeller 1308 is driven by a hydraulic motor or turbine (not shown) that is powered by the flow of pressurized water out from the interior of the spherical flotation module 1302 and back to the body of water 1301 via propeller effluent pipe 1309.
A second one-way valve 1306, positioned within an upper portion of the inertial water tube, allows water to pass from the body of water 1301 into the interior of hollow inertial water tube 1303/1304 and is configured to disallow water to pass in the reverse direction.
Embodiment 1300 floats on body of water 1301 when in its nominal operational configuration, and in the operational configuration shown, has a draft on its spherical hollow structure corresponding to approximately one radius of said structure.
First one-way valve 1307 is shown at the neck, and/or junction, 1337 where the inertial water tube and the spherical flotation module 1302 connect and is of a flap type. It allows fluid to pass preferentially from inertial water tube 1303/1304 into the interior of spherical flotation module 1302, e.g. when the pressure of fluid inside said inertial water tube just below neck 1337 is greater than the pressure of fluid in the bottommost part of the hollow interior of spherical flotation module 1302.
When the embodiment oscillates vertically due to forces imparted by waves traversing the surface 1301 of body of water on which the embodiment floats, the inertia of the water inside the inertial water tube 1303/1304 tends to cause that water to lag the oscillations of the embodiment, and/or to oscillate out of phase with the oscillations of the embodiment.
Consequently, especially (but not exclusively) when the embodiment is accelerating upwardly, a low-pressure region can develop in an upper portion of the tapered portion 1303 of the inertial water tube, tending to cause the second one-way valve 1306 to crack and/or open, allowing water to flow from the body of water 1301 on which the embodiment floats into the upper tapered portion 1303 of the inertial water tube. Subsequently, especially (but not exclusively) when the embodiment is accelerating downwardly, a high-pressure region can develop in an upper portion 1303 of the inertial water tube, causing the first one-way valve 1307 to crack and/or open, thereby allowing water to flow from the upper tapered portion 1303 of the inertial water tube into the hollow interior of the spherical flotation module 1302.
Accordingly, the embodiment acts like a pump, pumping water into the hollow interior of its spherical flotation module 1302, and compressing the volume of gas 1315 therein, thereby raising the pressures of both the gas and the water 1313 within the spherical flotation module.
In some embodiments, first one-way valve 1307 is replaced with other kinds of one-way or check valves (e.g. ball check valves, swing check valves, Tesla valvular conduits, or fixed-geometry passive check valves other than the Tesla valvular conduit). In some embodiments, second one-way valve 1306 is replaced with other kinds of one-way or check valves (e.g. ball check valves, swing check valves, Tesla valvular conduits, or fixed-geometry passive check valves other than the Tesla valvular conduit).
When the water accumulated within the embodiment's water reservoir 1313 achieves an elevated pressure, it has a tendency to flow outwardly into the body of water 1301 via any apertures in spherical flotation module 1302 that are available to it. In this embodiment, two such apertures are provided.
First, the pressurized water within the embodiment's water reservoir 1313 can flow outwardly via propeller motor 1320, which is fed and/or energized with pressurized water via propeller inlet pipe 1321, exhausts effluent water to the body of water 1301 on which the embodiment floats via propeller effluent pipe 1309, and includes a hydraulic motor or water turbine that converts energy from the flow of water through it into shaft power that drives propeller 1308, thereby propelling the embodiment across the surface 1301 of the body of water on which it floats. In other words, propeller 1308 is powered using mechanical power drawn directly from a flow of pressurized water that originates from within the embodiment's spherical flotation module 1302.
Second, the pressurized water within the embodiment's water reservoir 1313 can flow outwardly via turbine assembly 1310, which consists of an open conduit through which water can pass from the interior of spherical flotation module 1302 to the body of water 1301 on which the embodiment floats. The conduit through turbine assembly 1310 that connects the interior of spherical flotation module 1302 to the body of water 1301 on which the embodiment floats is partially obstructed by a water turbine 1311 (not resolved in detail in
The types of constricted tubes shown (and/or other similar types of constricted tubes that are not shown and are variants or modifications of the illustrated types of constricted tubes) can be used to replace (with appropriate modifications, including introducing one or more curvatures) the uppermost portion, and/or an upper portion, of the following components of the embodiments of this disclosure: (1) the inertial water tube 102 of the embodiment of
In each case, the decreasing horizontal cross-sectional area of the displayed inertial water tube (relative to water movement in an upward direction, i.e. relative to flow-normal and/or horizontal section planes of increasing elevation) causes upward-moving water within the inertial water tube to accelerate upward and to periodically “spill over” and/or out of an upper mouth of the inertial water tube so as to be trapped, and/or captured, within a respective water reservoir of a respective embodiment.
Most, if not all, of the types of inertial water tubes shown can be arrayed side-by-side with other different types of inertial water tubes to form a (heterogeneous) composite inertial water tubes likewise having more than one top mouth.
In the case of a composite inertial water tube, the constituent inertial water tubes of the composite inertial water tube can have geometries, constriction ratios, heights, diameters, etc., that differ from one another.
Most, if not all, of the types of inertial water tubes illustrated in
The inertial water tubes illustrated in
Note that the “tube” defined by tube wall 1440 of this type of inertial water tube is not itself constricted, but the partial introduction of conical plug 1441 into the inertial water tube effectively creates a constriction in the upward flow path of the water rising within the inertial water tube 1440, so that the combined apparatus can be called a constricted tube or tapered tube. Note too that the flow of water ejected from this constricted tube will tend to form an annular and/or conical sheet.
In some embodiments of the current disclosure, the spar 1442 can be lowered and raised, e.g. by a motor in response to signals generated by an embodiment's control system, so as to increase and decrease, respectively, the degree of tube constriction.
A lower portion 1453 of plug 1451 is approximately conical with its tip pointed downward. A middle portion 1451 of plug 1451 is cylindrical with its longitudinal axis oriented vertically and approximately coaxial with a longitudinal axis of the cylindrical wall 1450. An upper portion 1452 of plug 1451 forms a tapered water diverter than serves to direct a portion of an upward water flow laterally (i.e. radially outward from the inertial water tube).
The annular conduit defined by tube wall 1450 and solid plug 1451 is at first decreasing in flow-normal cross-sectional area in the region of the conical portion of the plug, relative to an upward direction of movement and/or flow, and then approximately constant in flow-normal cross-sectional area in the region of the cylindrical portion 1451 of the plug, relative to an upward direction of movement and/or flow. Five radial fins, e.g., 1454, rigidly connect the plug 1451 to the tube wall 1450.
Spar 1463 connects the conical plug to a support structure that is continuous with the hull of the embodiment. Conical plug 1462 can thus be suspended from a “ceiling” of the embodiment. Spar 1463 has a screw feature and/or linear gear bar (“rack”) feature 1464 which is inserted into, and operatively interfaces with, a motorized gear or pinion feature (not shown) affixed to the support structure from which the conical plug depends. This mechanism enables the conical plug to be raised and lowered according to the outputs of an electronic control system of the embodiment. Accordingly, the degree of constriction of the annular conduit 1465, and/or the flow-normal cross-sectional area of the annular conduit 1465, with respect to any particular flow-normal section within the portion of the inertial water tube into which the conical plug 1462 extends, can be altered. In other embodiments, other mechanisms can be used to raise or lower a plug feature so as to increase or decrease the constriction ratio of the relevant constricted inertial water tube.
Viewed from the bottom (
A similar alternate inertial water tube of swivel type has a tube channel, including both upper and lower tube segments, in which the flow-normal cross-sections (i.e., the sections in planes normal to a longitudinal axis of the tube) is approximately circular. However, the alternate tube configuration includes a bend in the tube proximate to the swivel. The upper and lower tubes are displaced by a bend in both the upper and lower tubes such that the top portion of the lower tube 1611 is bent so as to align the longitudinal axis of its channel with the axis of the swivel's rotation, and such that the lower portion of the upper tube 1613 is bent so as to also align the longitudinal axis of its channel with the axis of the swivel's rotation, thereby resulting in the longitudinal axes of the fully raised swivel inertial water tube not being coaxial, and thereby requiring water flowing upwardly through the inertial water tube to make a lateral diversion on its way to the upper mouth 1614.
Whereas, with respect to the swiveled tube configuration illustrated in
The buoyant embodiment 1650 floats adjacent to an upper surface of a body of water (not shown). A substantially hollow and approximately upper hull enclosure or buoy or spherical portion 1651 provides the embodiment with buoyancy. An approximately upper inner half of the buoy is filled with a gas (e.g., air, nitrogen, and/or hydrogen) that is compressed so as to exhibit a pressure that is greater than the pressure of the air outside the embodiment, i.e., greater than the atmospheric pressure at the upper surface of the body of water on which the embodiment floats. An approximately lower inner half of the buoy is filled with water, e.g., seawater, that has been injected, propelled, and/or added to the inside of the buoy as a result of wave action.
Connected to, and/or depending from, the buoy 1651 is a hollow inertial water tube 1652 through which water may rise and fall, e.g., in response to wave action, and through which water may enter the inside of the buoy 1651. An upper mouth and/or aperture (not visible) of the inertial water tube inside the buoy 1651 allows water to flow from the inside of the inertial water tube 1652 to the inside of the buoy 1651. A lower tube mouth and/or aperture and/or ingress orifice and/or ingress o 1653 of the inertial water tube allows water to flow between the inside of the tube 1652 and the body of water on which the embodiment floats.
Hollow inertial water tube 1652 is connected to hollow buoy 1651 by means of a connecting, curvaceous, concave, approximately frusto-conical annular collar 1654 that provides structural advantages.
The embodiment 1650 floats adjacent to an upper surface 1655 of a body of water, e.g., seawater.
In response to wave action, water flows into and out of aperture 1653 at the bottom of inertial water tube 1652. The walls of an upper portion of inertial water tube 1652 are tapered relative to an upward direction of flow, and impart periodic excitation forces to the water column inside said tube, causing periodic increases in pressure in the tapered portion and create an oscillatory water flow. Periodically, water rises within inertial water tube 1652 with enough speed, momentum, energy and/or power to cause a portion of that water to be ejected from an upper mouth (not visible) at the top of inertial water tube 1652 and into buoy 1651. The water ejected into, and thereby added to, the inner cavity of buoy 1651 must overcome the pressure of the gas trapped therein in order to be ejected into the interior of buoy 1651, and when ejected from the inertial water tube into the interior of buoy 1651 will tend to further compress the gas trapped therein, thereby further increasing the pressure of that gas.
When the level of the water within the buoy 1651 rises to a requisite first threshold level, a portion of that water will tend to flow into left and/or right turbine ingress tubes (not visible) inside the buoy thereby energizing respective water turbines therein and respective generators operatively connected to those water turbines. After passing through the respective water turbines, the effluent water flows out of the embodiment through respective left and right effluent apertures 1657 and 1656. The effluent from left and right effluent apertures 1657 and 1656 tends to generate a lateral thrust that tends to propel the embodiment across the surface 1655 of the body of water on which the embodiment floats in the direction of its front side (i.e., into the page with respect to the embodiment orientation illustrated in
If water is added to the inner cavity of buoy 1651 at a sufficient rate and/or to a sufficient degree, e.g., in response to vigorous wave action, then the level of the water within the buoy may rise to a vertical level that exceeds a second threshold level that is higher than the first threshold level. When the level of the water within the buoy 1651 reaches and/or exceeds the second threshold level, then a portion of that water will tend to flow into a central “overflow” effluent tube through which it will subsequently flow out of the embodiment and into the body of water 1655 on which the embodiment floats through overflow aperture 1658, thereby tending to add to the forward thrust generated by water flowing out of effluent apertures 1656 and 1657.
In response to wave action, the embodiment tends to oscillate vertically at the surface of the body of water on which it floats, and additionally the level of the water on and/or in which it floats tends to oscillate both which respect to its distance above the ground, e.g., the seafloor, beneath it and with respect to the top and bottom ends of the embodiment. These oscillations tend to cause water within the embodiment's inertial water tube 1652 to oscillate in directions approximately parallel to the longitudinal (and nominally vertical) axis of the inertial water tube. As a consequence of these oscillations, water from outside and/or below the embodiment tends to enter the inertial water tube through its lower mouth and/or aperture 1653, and sometimes flows out of the tube and returns to the body of water on which the embodiment floats through that same lower mouth and/or aperture 1653.
Similarly, as a consequence of these oscillations of water within inertial water tube 1652, and as a consequence of the narrowing, i.e., the reduction in the tube's flow-normal cross-sectional area, of that inertial water tube near an upper end of that tube, water sometimes exits and/or is ejected through an upper mouth and/or aperture and/or injection orifice 1659 of the inertial water tube. Water ejected from the upper mouth 1659 of the inertial water tube 1652 tends to collide with a conical water dispersion plug or “diverter” positioned above the tube's upper mouth and/or aperture 1659.
When the level of the water within the embodiment's buoy 1651 exceeds a first threshold level, a portion of the water trapped within the embodiment's buoy 1651, and pressurized by the displaced gas trapped therein, flows out of the buoy through left and right turbine effluent tubes (not visible). Water flowing out of the left and right turbine effluent tubes, exits the embodiment through respective left 1657 and right 1656 effluent apertures.
Water flowing 1661 out of the left effluent aperture 1657 tends to generate a thrust that in addition to propelling the embodiment laterally in a forward direction (i.e., down with respect to the bottom-up embodiment orientation illustrated in
Water flowing 1663 out of the right effluent aperture 1656 tends to generate a thrust that in addition to propelling the embodiment laterally in a forward direction (i.e., down with respect to the bottom-up embodiment orientation illustrated in
By adjusting, controlling, and/or regulating, the relative rates at which water flows out of the embodiment's left 1657 and right 1656 effluent apertures, e.g., as through the adjustment, control, and/or regulation, of the resistive torque of each effluent tube's respective water turbine, the embodiment's angular orientation at the surface of the body of water on which it floats may be adjusted, controlled, and/or regulated (i.e. yawed) relative to the embodiment's nominally vertical longitudinal axis, thereby permitting the embodiment to be steered such that the combination of that steering and the nominally forward thrusts and/or propulsion created, at least in part, by the water discharged through the embodiment's left 1657 and right 1656 effluent apertures can be used to cause the embodiment to travel in a desired and/or desirable direction, and/or toward and/or to a desired and/or desirable destination, e.g., towards and/or to a particular longitude and latitude, e.g., where waves are more energetic.
When the level of the water within the embodiment's buoy 1651 exceeds a second and/or “overflow” threshold level, a portion of the water trapped within the embodiment's buoy 1651, e.g., a portion of the water at or above the second threshold level within the embodiment's water reservoir, and pressurized by the gas trapped therein, flows out of the buoy through an overflow effluent tube, therethrough exiting 1665, and/or flowing out of, the embodiment through overflow aperture 1658. Such outflows tend to add to, and/or increase, the nominally forward thrust propelling the embodiment in a forward direction (i.e., downward with respect to the embodiment orientation illustrated in
The embodiment's buoy 1651 has a hollow interior chamber or hollow flotation capsule 1666 wherein a lower portion is nominally filled with water (thus constituting a water reservoir or water tank portion of the hollow interior chamber) and an upper portion is nominally filled with a pressurized gas (thus constituting a pressurized air enclosure portion of the hollow interior chamber). An annular upper portion of the wall of the embodiment's inertial water tube (1652 in
Water ejected from the upper mouth (1659 in
Water whose free surface has risen to or above a first water level that is at the vertical height of the upper edges 1669 and 1667 of the respective left 1671 and right 1672 turbine ingress tubes will tend to flow into those turbine ingress tubes therein encountering, engaging, and/or flowing through, respective left 1673 and right 1674 water turbines, positioned within constricted portions, 1675 and 1676 respectively, of those turbine ingress tubes. These turbines are one type of flow governor that helps retain a certain amount of water within the embodiment's reservoir, maintaining its waterline and certain of its hydrodynamic properties. When caused to rotate by water flowing through their respective turbine ingress tubes, water turbines 1673 and 1674 impart rotational kinetic energy and/or power to their respective operatively connected turbine shafts 1677 and 1678, which transmit a portion of that rotational kinetic energy to respective (not shown) left and right generators, thereby causing those generators to generate electrical power.
The left 1671 and right 1672 turbine effluent tubes (which are the continuations of the left and right turbine ingress tubes past the point at which the water therein flows through the respective left and right water turbines) pass through the wall of the buoy 1651 at positions 1679 and 1680 respectively. And, water discharged from the left 1671 and right 1672 turbine effluent tubes passes out of the embodiment through the respective external apertures (1657 and 1656 in
By varying the amounts of resistive torque and/or braking force applied to the left and right water turbines by their respective generators (e.g., alternators) the degrees to which the left 1673 and right 1674 water turbines retard, limit, reduce, inhibit, slow, and/or throttle, the rate at which water flows through the respective left 1671 and right 1672 turbine effluent tubes, and thereby the degrees to which the left 1673 and right 1674 water turbines retard, limit, reduce, inhibit, slow, and/or throttle, the rate at which water is discharged from, and/or flows out of, the respective left 1657 and right 1656 external apertures, the embodiment's control system (not shown) can adjust, control, and/or regulate, the magnitude of the propulsive thrust generated by the effluent of each water turbine. When the propulsive thrust generated by the water discharged from one external aperture is unequal to the propulsive thrust generated by the water discharged from the other external aperture, then a torque is applied to the embodiment about a vertical longitudinal axis thereby tending to cause the embodiment to turn. Thus, by controlling, adjusting, altering, and/or regulating, the amount of resistive torque applied to the left and right water turbines, the direction in which the embodiment moves and/or travels in response to the propulsive thrusts generated by the water flowing out of the embodiment can be controlled, adjusted, altered, and/or regulated, i.e., the embodiment can be steered in a direction across the surface of the body of water on which the embodiment floats.
Water whose free surface has risen to or above a second water level that is at the vertical height of the upper edge (not visible beneath the water dispersion plug 1668) of an overflow effluent tube 1681 will tend to flow into the overflow effluent tube and therethrough flow out of the embodiment. The upper edge of the overflow effluent tube defines the second “overflow” threshold water level. The overflow effluent tube 1681 passes through the wall of the buoy 1651 at position 1682. And, effluent water discharged from the overflow tube 1681 passes out of the embodiment through the respective external aperture (1658 in
Operatively connected to the shafts 1677 and 1678 of the respective left and right water turbines (1673 and 1674 in
When water within a lower portion of the interior 1666 of the embodiment's buoy 1651 rises above the upper mouths, apertures, and/or edges 1669 and 1670 of the respective left and right turbine ingress tubes 1671 and 1672, then a portion of that water may flow into those respective turbine ingress tubes. However, if the level of the water within the lower portion of the interior 1666 of the embodiment's buoy 1651 rises even further, and exceeds the height and/or level of the upper mouth, aperture, and/or edge 1685 of the overflow effluent tube 1681, then a portion of that water may flow into the overflow effluent tube and therethrough flow out of the interior 1666 of the buoy 1651, thereby relieving and/or reducing the excessive water level and/or water volume to a nominal level and/or volume.
A lower wall 1686 of the embodiment's buoy 1651 is attached to, and/or fused with, an upper portion 1667 of the embodiment's inertial water tube 1652/1667 thereby sealing the interior 1666 of the buoy with a contiguous, continuous, and/or unbroken wall that is formed in part by a portion 1667 of the inertial water tube's wall. Adjacent to and/or above the annular junction and/or seam of the tube 1652/1667 and the buoy 1651, the tube 1667 constricts thereby tending to propel water rising within, and/or relative to, the inertial water tube 1652/1667 up to, and against, the embodiment's water dispersion plug 1668.
Because of the elevated pressure (i.e., above and/or greater than the pressure of the atmosphere outside the embodiment) the average, typical, and/or resting surface of the water within the embodiment's inertial water tube 1652/1667 will tend to be lower than the average, typical, and/or resting surface (1655 in
In response to waves traveling across the surface 1655 of the body of water on which the embodiment (1650 in
As water flows from the upper mouth of the inertial water tube 1667 into the water reservoir 1666B within the interior of the buoy 1651, the level 1691 of the water in the reservoir 1666B will tend to rise, and the volume of the pocket of air 1666A trapped within the buoy and nominally above the level 1691 of the water 1666B trapped therein tends to be reduced and/or compressed, tending to increase the pressure of both the air 1666A and water 1666B. Conversely, and in complementary fashion, as water flows out of the water reservoir 1666B through the left 1671 and/or right (not visible) turbine ingress tubes, or through the overflow effluent tube 1681, the pressure of both the pocket of air 1666A and the water 1666B trapped within the buoy tend to be reduced.
If the level 1691 of the water 1666B trapped within the water reservoir 1666B within the buoy 1651 exceeds the level 1692 of the upper mouth and/or aperture of the overflow effluent tube 1681, then water will tend to flow out of the water reservoir 1666B and into the overflow effluent tube 1681, and therethrough flow 1661 out of the embodiment, thereby tending to generate a forward thrust. Water flowing out of the water reservoir 1666B through the left turbine effluent tube 1671 will likewise flow 1665 out of the embodiment, thereby tending to generate a forward thrust. (While not visible in the sectional illustration of
A portion of the electrical power generated by the left 1683 and right (not visible) generators is provided to, and consumed by, a plurality of lights and/or lamps, e.g. 1687, that are attached and/or connected to an inner surface of the buoy beneath the surface 1691 of the water within the water reservoir 1666B positioned inside the buoy 1651. In other embodiments, lights or lamps are positioned on upper interior walls of buoy 1651 or elsewhere within the hollow interior of buoy 1651, in such a manner as to illuminate a large portion of, if not all of, that volume. In still other embodiments, lights or lamps are positioned on, and/or attached to, both upper and lower interior walls of buoy 1651, i.e., positioned both above the water 1666B and submerged within the water 1666B. The scope of the present disclosure includes embodiments with lights and/or lamps positioned on, and/or attached to, any location on, in, and/or within the embodiment. The scope of the present disclosure includes embodiments with lights and/or lamps positioned on, and/or attached to, any location on an exterior surface and/or wall of the embodiment (e.g., such that that light produced radiates into the water outside and/or around the embodiment). The scope of the present disclosure includes embodiments with lights and/or lamps that are suspended by cables (e.g., electrical cables) at various locations throughout the embodiment, e.g., within the water reservoir and/or within the inertial water column. Such suspended lights and/or lamps might depend from any surface, wall, and/or structural member within the embodiment.
The electromagnetic radiation, e.g. 1693, emitted by the embodiment's lamps, e.g. 1687, may be consumed by micro or macro algae growing within the water reservoir 1666B, or plants of any type. Such algae or plants may be suspended in the water of the water reservoir of the embodiment, or may be attached to ropes, fabrics, or other substrates contained within the water reservoir of the embodiment.
In one embodiment, designed to promote the growth of macroalgae, an approximately circular net 1694 spans, and/or is adjacent to, an approximately flow-normal and/or horizontal cross-section of the water reservoir 1666B, adjacent to the surface 1691 of the water reservoir. Net 1694 entrains macroalgae within the lower portion of the water reservoir 1666B thereby tending to reduce, if not prevent, the outflow and/or loss of that macroalgae through the turbine tubes, e.g. 1671, and/or overflow tube 1681. In other embodiments, other means (e.g. a sieve, catchment, mesh, or grating) are positioned in the path of water flow to the turbine in order to prevent outflow or loss of macroalgae and/or other organisms such as fish.
Periodically, algae may be removed from the reservoir 1666B by a ship, platform, or other vessel. A ship may insert a suction tube into and through the upper mouth 1695 of an algae access tube 1696. Such a suction tube may be extended through the algae access tube until an end of the suction tube passes through the lower mouth 1697 thereof and therethrough into the reservoir 1666B.
Once inserted into and through the algae access tube 1696, the lower mouth of an inserted suction tube can be positioned near the bottom of the embodiment's reservoir 1666B and suck out a portion of the algae therein. A complementary algae access tube (not shown), and/or a complementary channel within a single algae access suction tube, can return water to the reservoir while algae, and/or algae and water, are being removed from the reservoir, thereby maintaining and/or preserving the original level 1691 of the water in the water reservoir 1666B.
The algae access tube allows algae, water, nutrients, and/or other materials, to be added to, and/or withdrawn from, 1698 the water reservoir 1666B when that reservoir is otherwise sealed inside the buoy 1651. Because the algae access tube 1696 is open to the atmosphere at its upper mouth 1695, and open to the water and algae in the reservoir 1666B at its lower mouth 1697, water from the reservoir is free to rise up within the algae access tube 1696. Because of the pressure of the air trapped within the upper portion 1666A of the interior of the buoy 1651, and the corresponding pressure of the water 1666B, the surface 1699 of the water within the algae access tube 1696 tends to rise to a height 1700 above the surface of the water within the water reservoir 1666B whose head pressure approximately corresponds to the pressure of the air within buoy 1651.
In addition to growing algae, especially macroalgae, within the reservoir 1666B inside the buoy 1651, algae, especially macroalgae, may be grown inside the embodiment's inertial water tube 1652. An upper barrier net 1701 spanning an upper portion, and/or at an upper position, of the inertial water tube 1652 prevents at least a portion of the algae within the inertial water tube from too closely approaching the upper constricted portion 1667 of the inertial water tube which, if not prevented, could potentially clog the inertial water tube at that location.
Macroalgae is grown within a net enclosure and/or algae containment bag 1702 that forms a porous bag entraining most, if not all, of the algae. An upper end of the algae containment bag 1702 is pulled upward by a float 1703, tending to position the upper end of the bag proximate to the lower side of the barrier net 1701. The algae within the algae containment bag 1702 are encouraged to grow through the embodiment's provision of light, e.g. 1704, emitted by lamps, e.g. 1705, positioned along the interior wall and/or surface of the inertial water tube 1652. The tube lamps, e.g. 1705, are similar or identical to the lamps, e.g. 1687, positioned within the inside of the buoy 1651, although each set of lamps, i.e. those within the buoy 1651 and those within the embodiment's inertial water tube 1652, may emit light(s) of differing frequencies and/or wavelengths so as to more optimally encourage the growths of differing species of algae.
A lower end of the algae containment bag 1702 is pulled downward by a weight 1706 connected to the bag by a tether, chain, rope, linkage, and/or cable 1707. Also connected to the weight 1706, and therethrough to the algae containment bag 1702, is a tether, chain, rope, linkage, and/or cable 1708 an upper end of which is connected to a float 1709 that tends to float at the surface 1655 of the body of water on which the embodiment floats.
Periodically, algae may be removed from the embodiment's inertial water tube 1652 by a ship or other vessel. A ship may attach a secondary cable to cable 1708 and then lower a secondary weight to increase the total weight tending to pull the algae containment bag 1702 down and out of the tube 1652. After the algae containment bag has been pulled down and become free of the inertial water tube 1652, the algae containment bag may be pulled up by the secondary cable and therewith lifted onto and/or into the ship where its algal contents may be harvested. The same algae containment bag that was removed may be reinserted into the inertial water tube using the same second cable, using an underwater autonomous vehicle, and/or using another method, mechanism, and/or system. If the same algae containment bag is reinserted into the embodiment's inertial water tube, it will tend to be so reinserted after most, but not all, of its entrained algae has been harvested and/or removed. By leaving a portion of the algae in the algae containment bag, the residual algae can grow and give rise to another harvest. If a “new” second algae containment bag is inserted into the embodiment's inertial water tube 1652 to replace the removed algae containment bag, then it is advantageous to first “seed” that algae containment bag with algal stock so that a new crop of a preferred species of algae can be grown.
The scope of the present disclosure includes a complementary ship to periodically harvest the algal crops grown within the embodiment, as well as the facilities on a shore, floating platform, and/or other ship where the harvested algae are processed and/or stored, as well as a method for harvesting algae wherein:
The embodiment aquaculture configuration illustrated in
The scope of the present disclosure includes, but is not limited to, the growth and/or harvesting of any and every kind of microalgae, macroalgae, fish, crustacean. Fish that do not eat the varieties of algae grown may nonetheless receive nutrition, e.g. plankton and phytoplankton, from the water that is regularly introduced to the reservoir 1666B and inertial water tube 1652 as a result of wave action. In addition to introducing potentially nutrient-rich water from outside the embodiment into the water reservoir 1666B and inertial water tube 1652 as a result of wave action, the embodiment also tends to remove waste-containing and/or nutrient-depleted, water from the water reservoir and inertial water tube as a result of the same water cycle (i.e. water enters tube 1652, and therefrom enters the water reservoir 166B, and thereafter flows out of the water reservoir through the turbine ingress and effluent tubes and/or through the overflow effluent tube).
The scope of the present disclosure includes embodiments utilizing water reservoir lamps and/or inertial water tube lamps emitting light of any single wavelength, any range of wavelengths, and/or any combinations of wavelengths or ranges of wavelengths.

The scope of the present disclosure includes embodiments in which lamps are attached to the outer surfaces of the buoy and/or tube thereby encouraging algal growth, and the establishment of communities of fish, outside the embodiment, but in the vicinity of the embodiment.
The scope of the present disclosure includes embodiments utilizing their wave-generated energy to create high-pressure water suitable for the desalination of seawater, and/or for the extraction of minerals from seawater.
The scope of the present disclosure includes embodiments which utilize and/or consume a portion of the electrical power that they generate to electrolyze water, e.g. seawater, so as to produce hydrogen gas. The scope of the present disclosure includes embodiments that store at least a portion of the hydrogen gas that they produce within the air pocket 1666A inside their respective buoys.
The scope of the present disclosure includes embodiments comprised of buoys of any size, dimension, diameter, volume, 3D volumetric shape, 2D cross-sectional shape(s).

A buoyant embodiment 1800, buoy, and/or hollow flotation module, floats adjacent to an upper surface 1801 of a body of water. A substantially hollow and approximately spherical portion 1800 and/or buoy provides the embodiment with buoyancy. An approximately upper inner half of the buoy is filled with a gas (e.g., air, nitrogen, and/or hydrogen) that is compressed so as to exhibit a pressure that is greater than the pressure of the air outside the embodiment, i.e., the atmospheric pressure at the upper surface of the body of water on which the embodiment floats. The gas occupying this approximately upper half of the buoy can be pressurized by the device's own pumping action in waves, or by an external source of pressurized gas (such as a hose connected to the embodiment to pressurize it prior to deployment). An approximately lower inner half of the buoy is filled with water, e.g., seawater, that has been injected, propelled, and/or added to the inside of the buoy as a result of wave action.
Connected to, and/or depending from, the buoy 1800 is a hollow inertial water tube 1802 through which water may rise and fall, e.g., in response to wave action, and through which water may enter the inside of the buoy 1800. An upper mouth and/or aperture (not visible) of the inertial water tube inside the buoy 1800 allows water to flow from the inside of the inertial water tube 1802 to the inside of the buoy 1800. A lower tube mouth and/or aperture 1803 of the inertial water tube allows water to flow 1804 between the inside of the inertial water tube 1802 and the body of water 1801 on which the embodiment floats.
Hollow inertial water tube 1802 is connected to hollow buoy 1800 by means of a connecting, curvaceous, concave, approximately frustoconical annular collar 1805. An effluent pipe, tube, and/or channel 1806 connected to and embedded in the annular collar 1805 allows water, e.g., seawater, as well as any sediments, detritus, fish waste, and/or other non-fluid materials that drift down within the water that tends to fill the approximately lower inner half of the buoy, to be discharged 1807 from the embodiment through effluent mouth and/or aperture 1808. The effluent discharged 1807 through the mouth 1808 of effluent pipe 1806 tends to generate a lateral thrust which tends to propel the embodiment across the surface 1801 of the body of water on which the embodiment floats in a direction substantially opposite the direction of the discharge. Mouth 1808 (also referred to as an external effluent port) is in this embodiment a form of nozzle or constriction that creates a pressure drop or pressure gradient between the interior reservoir of the inside of buoy 1800 and the external seawater at or in the vicinity of mouth/external effluent port 1808. In this manner, the nozzle formed by mouth 1808 is a flow governor and serves a flow governing function, limiting the rate at which water can leave the interior of the embodiment. The nozzling effect created by mouth 1801 also accelerates the flow being discharged from effluent pipe 1806 and therefore increases the thrust capacity of the embodiment.
Excessive water pressure inside the embodiment's interior water reservoir (not visible inside the buoy 1800) causes water from inside the embodiment to push up through water pressure-relief pipe 1809 with enough force, and to a sufficient height, to be discharged 1810 from the embodiment thereby relieving and/or reducing the pressure inside the embodiment. Similarly, excessive air pressure inside the embodiment's interior, i.e., pressure within the pocket of air trapped above the water reservoir (not visible inside the buoy 1800) causes air from inside the embodiment to push down through air pressure-relief pipe 1811 with enough force, and to a sufficient depth, to be discharged 1812 from the embodiment (e.g., creating bubbles rising from the lower aperture of the air pressure-relief pipe 1811) thereby relieving and/or reducing the pressure inside the embodiment.
Attached to an upper surface and/or wall of the embodiment's buoy 1800 is a control chamber 1813 containing, housing, and/or protecting, within, an air pressure control system (not shown). Attached to an upper surface and/or wall of the control chamber 1813 is a photovoltaic generator 1814 comprising four crossed vertical walls mounted atop a lower horizontal wall. On both broad surfaces, e.g., front and back, of each vertical wall, and on the upper broad surface of the lower horizontal wall, are mounted, attached, connected, and/or incorporated, solar cells and/or another conversion mechanism, circuit, device, technology, and/or solar receptor, that tends to generate electrical power in response to incident solar illumination 1815 and/or radiation. A storage cell, module, device, and/or element, e.g., a capacitor, battery, switched induction coil, and/or other energy storage device, is incorporated, included, and/or positioned, within the control chamber 1813 and stores electrical power generated by the photovoltaic generator 1814 so that it can be available at any time (e.g., when the sun isn't shining on the embodiment).
The air pressure control system controls, activates, energizes, adjusts, and/or utilizes, an air pump 1816 to pump air 1817 (or to not pump air, e.g., when deactivated) from the atmosphere into the interior of, and/or into the air pocket within, the buoy 1800 through an air injection pipe 1818, thereby tending to raise the pressure of the air within the buoy. The air pressure control system controls and energizes the air pump 1816 via a cable 1819.
The air pressure control system controls, activates, energizes, adjusts, opens, closes, and/or utilizes, an air valve 1820 to release pressurized air 1817 from inside the air pocket (not visible) within the buoy 1800 to the atmosphere by opening the air valve (or to not release pressurized air, e.g., when the air valve is closed), thereby tending to reduce the pressure of the air within the buoy (i.e., when the valve is open). The air pressure control system opens and closes the air valve 1820 via a cable 1822.
As the embodiment is moved up and down by waves passing across the surface 1801 of the body of water on which the embodiment floats, water entrained within its inertial water tube 1802 tends to oscillate. The water 1823 within the inertial water tube 1802 is shielded from a substantial portion of the wave motion outside the inertial water tube. And, the lower mouth 1803 of the inertial water tube tends to be at a depth near, at, or below, a wave base of the water 1801 on which the embodiment floats. As the water 1823 within the inertial water tube 1802 oscillates and/or moves up and down in response to wave action at the embodiment, water tends to move 1804 in and out of the lower mouth 1803 of the inertial water tube 1802, and the surface 1824 of the water within the inertial water tube 1802 tends to move 1825 up and down. Occasionally, water within the inertial water tube 1802 moves upward within the inertial water tube fast enough, and to a great enough height, that a portion of it escapes 1826 the upper mouth 1827 of the inertial water tube, thereby tending to fall into, and/or be deposited within, a water reservoir 1827, and thereby tending to increase the volume of water therein, and the height 1828 of its upper surface within the buoy 1800.
Water oscillating within a lower portion of inertial water tube 1823 will tend to have a first amplitude (e.g., flow-parallel and/or longitudinal distance traveled during an oscillation). However, water oscillating within an upper portion 1828 of the inertial water tube will experience a narrowing, constricting, and/or constriction, in the flow-normal cross-sectional area of the tube and/or channel as it rises, and/or travels upward, within the tube. The narrowing of the inertial water tube proximate to the upper mouth 1827 of the inertial water causes water rising therein to be accelerated upward which is useful in increasing, raising, optimizing, and/or maximizing, the rate at which water is ejected 1826 from the upper mouth 1827 of the inertial water tube 1802.
An uppermost portion 1829 of the inertial water tube has an approximately constant flow-normal cross-sectional area and tends to permit upwardly-accelerated water to be ejected from an upper inertial water tube mouth 1827 that is positioned above the nominal surface 1828 of the water reservoir into which its ejections of water are captured, collected, cached, stored, and/or saved. With respect to a particular wave climate, the illustrated embodiment 1800 might achieve an optimal rate of water ejection 1826 when its narrowed, constricted, and/or frustoconical portion 1828 is positioned such that the nominal, average, modal, typical, and/or resting, upper surface 1824 of the water 1823 within its inertial water tube 1802 is adjacent to, and slightly below, the seam, junction, and/or boundary, 1830 at which the uppermost and narrowest portion of the frustoconical portion 1828 joins the lowermost portion of the cylindrical portion 1829. In the absence of the upper cylindrical portion 1829 of the inertial water tube, the inertial water tube would need to eject water at, or even below, the surface 1828 of the water reservoir 1827—which would tend to allow water from the water reservoir to spill back into the inertial water tube and be “wasted”. And, in the absence of the upper cylindrical portion 1829 of the inertial water tube, if the potential for spillage from the water reservoir 1827 back into the upper mouth 1827 of the inertial water tube was to be avoided, then the constricting of the upper portion 1828 of the inertial water tube would need to be continued so as to position the upper mouth 1827 further above the surface 1828 of the water reservoir. Such additional constriction might reduce the rate at which water was ejected 1826 from the upper mouth 1827 of the inertial water tube and/or otherwise impair the efficiency of the embodiment.
The inclusion of an uppermost portion of inertial water tube in which the flow-normal cross-sectional area is relatively and/or approximately constant can be useful in permitting, and/or making practical, an embodiment design in which a constricted portion of optimal design (e.g., a frustoconical portion of optimal included angle, length, and lower diameter) is placed at an optimal depth relative to the resting surface 1801 of the outside water. The embodiment illustrated in
The embodiment includes, incorporates, and/or utilizes, an air pressure control system (not visible within a control chamber 1813 attached to an outer upper surface of the buoy 1800) that is able to pump air from 1817 the atmosphere into 1832 the pressurized air pocket 1831 within the buoy when it is necessary or advantageous to raise the pressure of the air within that air pocket. The embodiment's air pressure control system that is also able to release air from 1833 within the pressurized air pocket 1831 within the buoy and into 1821 the atmosphere when it is necessary or advantageous to reduce the pressure of the air within that air pocket.
The embodiment also has a water pressure-relief pipe 1809 that is fluidly connected to the water reservoir through a lower mouth 1834. The pressure of the water 1827 within the water reservoir tends to force a portion of that water up and into the water pressure-relief pipe, where the level 1835 to which that water rises tends to be determined by, and/or a consequence of, the difference and/or delta of pressure of the air 1831 above the water reservoir and the pressure of the atmosphere outside the embodiment. If and when the pressure difference is “too high” then water from the water reservoir 1827 will tend to be raised past the height of the upper mouth of the water pressure-relief pipe 1809 and then be discharged 1810 outside the embodiment, thereby relieving and/or reducing the surplus pressure within the buoy 1800.
The embodiment also has an air pressure-relief pipe 1811 that is fluidly connected to the air pocket 1831 through an upper mouth 1836 and to the water 1801 outside the embodiment through a lower mouth. The pressure of the air within the air pocket 1831 tends to force a portion of that air into and down the air pressure-relief pipe, thereby tending to push down the water that would otherwise rise within the air pressure-relief pipe, e.g., until it reached the height of the surface 1828 of the water reservoir. The level 1837 to which the water within the air pressure-relief pipe is pushed down tends to be determined by, and/or a consequence of, the difference and/or delta of pressure of the air 1831 above the water reservoir and the pressure of the water 1801 outside the embodiment at the depth of the lower mouth of the air pressure-relief pipe. If and when the pressure of the air within the embodiment's air pocket 1831 exceeds the pressure of the water outside the lower mouth of that pipe then air from the air pocket 1831 will tend to be pushed down and out (perhaps tending to create bubbles as illustrated in
The water 1823 within the embodiment's inertial water tube 1802 tends to move up and down and/or to oscillate in directions approximately parallel to a flow-parallel longitudinal axis of the inertial water tube. However, when the embodiment is buffeted by a sufficiently vigorous wave climate, then with respect to a period and/or interval of three or more wave periods, there is nominally, and/or tends to be, a net flow of water from the body of water 1801 on which the embodiment floats into the inertial water tube 1802 through the lower mouth 1803 of the inertial water tube. Similarly, when the embodiment is buffeted by a sufficiently vigorous wave climate, then with respect to a period and/or interval of three or more wave periods, there is nominally, and/or tends to be, a net flow of water 1823 from the interior of the inertial water tube 1802 through the upper mouth 1827 of the inertial water tube and into the water reservoir 1827.
As the embodiment moves up and down in response to waves at the surface 1801 of the body of water on which it floats, and the water within its inertial water tube 1802 moves up and down, and the embodiment's movements and the movements of the water within the embodiment's inertial water tube are often out of phase. These out of phase movements of the embodiment and the water 1823 within the embodiment's inertial water tube occasionally and/or periodically cause water within the inertial water tube to be ejected 1826 from the upper mouth 1827 of the inertial water tube, thereby adding water to the water reservoir 1827 within the buoy 1800 and compressing the air within the air pocket 1831 above that water reservoir.
This influx of water from inside the inertial water tube 1802 into the water reservoir 1827 is nominally balanced, at least to an approximate degree, by an outflow 1807 of water from the water reservoir and back into the body of water 1801 at approximately the same average rate of flow. Water within the embodiment's water reservoir 1827 tends to flow downward and pass through 1838 a grating, mesh 1839, screen, and/or porous sheet of material, with the approximate shape of a flat annular disk. After flowing and/or passing through the annular-disk-shaped grating 1839, water from the embodiment's water reservoir 1827 flows through, and/or within, the annular space and/or void between the inner inertial water tube 1828 and the outer annular collar 1805, therethrough flowing out 1807 of the embodiment through the effluent mouth 1808 of effluent pipe 1806.
Because water from this embodiment's water reservoir flows through a grating positioned at a bottommost portion and/or end of the water reservoir, and thereafter through an effluent pipe positioned below that grating, this embodiment is well suited for the cultivation of fish, as the fish would tend to be retained within the water reservoir, i.e., by the gratings 1839 covering the effluent channel 1805/1806 at the bottom of the water reservoir, even as water flows through the water reservoir and is returned to the body of water 1801 from which it was captured.
An embodiment similar to the one illustrated in
Fish and/or macroalgae grown within such an embodiment might be harvested by a ship, platform, or other non-rigidly connected object through the connection of a hose to the upper mouth of water pressure-relief pipe 1809, after which at least a portion of the contents of the buoy's water reservoir 1827 could be collected, harvested, and/or removed, from the embodiment by a low-pressure “sucking” mechanism positioned on, and/or controlled by, the harvesting ship, platform, or other object. Such a sucking of the water, fish, and/or macroalgae from the water reservoir 1827 of such an embodiment would tend to draw water from the body of water 1801 on which the embodiment floats into the effluent mouth 1808 of the effluent pipe 1806 and therethrough into the water reservoir 1827 so as to replace at least a portion of the water removed by the sucking.
The embodiment illustrated in
When the navigational control system causes and/or signals the air pressure control system to increase the pressure of the air within the air pocket 1831, the resulting increase in air pressure tends to cause the mean, modal, and/or resting, upper surface 1824 of the water 1823 within the embodiment's inertial water tube 1802 to move further down the inertial water tube (i.e., towards its lower mouth 1803). Such a repositioning of the upper surface of the water within the inertial water tube tends to reduce the average rate at which water flows out of, and/or is ejected from, the upper mouth 1827 of the inertial water tube. That reduction in the rate at which water flows out of, and/or is ejected from, the upper mouth 1827 of the inertial water tube, tends to cause a related reduction in the rate at which water is discharged 1807 from the embodiment through effluent pipe 1806, although the water may be at higher pressure.
By contrast, when the navigational control system causes and/or signals the air pressure control system to decrease and/or reduce the pressure of the air within the air pocket 1831, the resulting decrease in air pressure tends to cause the mean, modal, and/or resting, upper surface 1824 of the water 1823 within the embodiment's inertial water tube 1802 to move further up the inertial water tube (i.e., towards its upper mouth 1827). Such a repositioning of the upper surface of the water within the inertial water tube tends to increase the rate at which water flows out of, and/or is ejected from, the upper mouth 1827 of the inertial water tube. That increase in the rate at which water flows out of, and/or is ejected from, the upper mouth 1827 of the inertial water tube, tends to cause a related increase in the rate at which water is discharged 1807 from the embodiment through effluent pipe 1806, which in turn tends to increase the thrust generated by that discharge.
The embodiment's navigational control system enables the embodiment to steer an approximate course across the surface of the water 1655 on which the embodiment floats. It also enables the embodiment to adjust the embodiment's sensitivity to the ambient wave environment so as to maintain, to an approximate degree, and within certain limits, a constant rate of electrical power production, e.g., by the embodiment's generators if a turbine and generator are positioned in the effluent pipe 1806.
When the embodiment's navigational control system detects that the angular and/or radial orientation of embodiment's effluent pipe 1806, and the corresponding angular and/or radial orientation of the thrust resulting from the discharge of water through that effluent pipe, is favorable relative to a course and/or direction in which the navigational control system would opt to send and/or direct the embodiment, then the navigational control system can and/or may signal the air pressure control system to reduce the pressure of the air within the air pocket 1831 and thereby increase the magnitude of the thrust generated by the water discharge through effluent pipe 1806.
When the embodiment's navigational control system detects that the angular and/or radial orientation of embodiment's effluent pipe 1806, and the corresponding angular and/or radial orientation of the thrust resulting from the discharge of water through that effluent pipe, is not favorable relative to a course and/or direction in which the navigational control system would opt to send and/or direct the embodiment, then the navigational control system can and/or may signal the air pressure control system to increase the pressure of the air within the air pocket 1831 and thereby reduce the magnitude of the thrust generated by the water discharge through effluent pipe 1806.
The embodiment's navigational control system monitors the, at least in part stochastic, wave, current, wind, and tidal, induced orientations and/or changes in orientation of the embodiment, and adjusts the embodiment's thrust to move the embodiment forward more quickly when the embodiment happens to be oriented (relative to a nominally vertical and/or flow-parallel longitudinal axis of the embodiment) in a favorable direction, and to move the embodiment forward more slowly when the embodiment happens to be oriented (relative to a nominally vertical and/or flow-parallel longitudinal axis of the embodiment) in an unfavorable direction.
An embodiment of the present disclosure that is similar to the one illustrated in
In embodiments with a generator, when the embodiment's navigational control system detects that the amount of electrical power being generated is too great, or when it detects that the amount of resistive torque being applied to a turbine is too low, e.g., in order to promote a maximal outflow of water from the embodiment's water reservoir and into the body of water 1655 on which the embodiment floats, thereby creating a risk that the resistive torque may be eliminated entirely and thereby expose the water turbine(s) to a “runaway” condition that might damage them, or when it detects, e.g., via onboard accelerometers, that the motions and/or movements of the embodiment are too vigorous, e.g., thereby threatening the structural integrity of the embodiment, then the embodiment's navigational control system can and/or may signal the air pressure control system to increase the pressure of the air within the air pocket 1831 and thereby tend to increase the volume of the air pocket within the hollow flotation module by displacing a portion of the water within the embodiment's water reservoir, which would tend to decrease the depth of the embodiment, lower the embodiment's waterline, and decrease the embodiment's waterplane area.
Such a lifting of the embodiment a distance out of and/or above the surface 1655 of the water would tend to decrease the relative and absolute amounts of energy imparted to it by the passing waves, and to decrease the relative and absolute rate at which water flows into the embodiment's water reservoir through the upper mouth of the inertial water tube. The reduced inflow of water from the inertial water tube into the water reservoir will tend to allow the amount of resistive torque being applied to the respective left and right water turbines to be increased (i.e., to slow the outflow of water from the water reservoir and to get relatively more power from that slower outflow). The reduced mass and inertia of the embodiment, as well as its reduced displacement volume, would tend to reduce the magnitude of the motions and/or movements to which the embodiment is subjected by passing waves, e.g., as the embodiment would tend to be floating higher above those wave and obstructing them to a lesser degree.
When the embodiment's navigational control system detects that the amount of electrical power being generated by its respective left and right generators is too low, or when it detects, e.g., via onboard accelerometers, that the motions and/or movements of the embodiment are lacking sufficient vigor, e.g., thereby suggesting that the embodiment is floating in a portion of a body of water 1655 characterized by a weak, poor, and/or feeble, wave climate, then the embodiment's navigational control system can and/or may signal the air pressure control system to decrease the pressure of the air within the air pocket 1831 and thereby tend to decrease the volume of the air pocket within the hollow flotation module and encourage an increase in the volume of the embodiment's water reservoir, which would tend to increase the depth of the embodiment, raise the embodiment's waterline, and increase the embodiment's waterplane area.
Such a lowering of the embodiment further below the surface 1655 of the water would tend to increase the relative and absolute amounts of energy imparted to it by the passing waves, and to increase the relative and absolute rate at which water flows into the embodiment's water reservoir through the upper mouth of the inertial water tube. The increased inflow of water from the inertial water tube into the water reservoir will tend to allow the embodiment's generators to generate a greater amount of electrical power.
The illustrated embodiment 1850 is very similar to the embodiment illustrated in
Connected to, and/or depending from, the buoy 1800 is a hollow inertial water tube 1852 through which water may rise and fall, e.g., in response to wave action, and through which water may enter the inside of the buoy 1850. An upper mouth and/or aperture (not visible) of the inertial water tube inside the buoy 1850 allows water to flow from the inside of the inertial water tube 1852 to the inside of the buoy 1850. A lower tube mouth and/or aperture 1853 of the inertial water tube allows water to flow 1854 between the inside of the inertial water tube 1852 and the body of water 1851 on which the embodiment floats.
Hollow inertial water tube 1852 is connected to hollow buoy 1850 by means of a connecting, curvaceous, concave, approximately frustoconical annular collar 1855. An effluent pipe, tube, and/or channel 1856 fluidly connected to the annular collar 1855 allows water, e.g., seawater, to be discharged 1857 from the embodiment through effluent mouth and/or aperture 1858. The effluent discharged 1857 through the mouth 1858 of effluent pipe 1856 tends to generate a lateral thrust which tends to propel the embodiment across the surface 1851 of the body of water on which the embodiment floats in a direction substantially opposite the direction of the discharge.
Excessive air pressure inside the embodiment's interior, i.e., pressure within the pocket of air trapped above the water reservoir (not visible inside the buoy 1850) causes air from inside the embodiment to push down through air pressure-relief pipe 1859 with enough force, and to a sufficient depth, to be discharged 1860 from the embodiment (e.g., creating bubbles rising from the lower aperture of the air pressure-relief pipe 1859) thereby relieving and/or reducing the pressure inside the embodiment.
Attached to an upper surface and/or wall of the embodiment's buoy 1850 is a control chamber 1861 containing, housing, and/or protecting, within, an air pressure control system (not shown). Attached to an upper surface and/or wall of the control chamber 1861 is a photovoltaic generator 1862 comprising four crossed vertical walls mounted atop a lower horizontal wall. On both broad surfaces, e.g., front and back, of each vertical wall, and on the upper broad surface of the lower horizontal wall, are mounted, attached, connected, and/or incorporated, solar cells and/or another conversion mechanism, circuit, device, technology, and/or solar receptor, that tends to generate electrical power in response to incident solar illumination 1863 and/or radiation. A storage cell, module, device, and/or element, e.g., a capacitor, battery, switched induction coil, and/or other energy storage device, is incorporated, included, and/or positioned, within the control chamber 1861 and stores electrical power generated by the photovoltaic generator 1862 so that it can be available at any time (e.g., when the sun isn't shining on the embodiment).
The air pressure control system controls, activates, energizes, adjusts, and/or utilizes, an air pump 1864 to pump air 1865 (or to not pump air, e.g., when deactivated) from the atmosphere into the interior of, and/or into the air pocket within, the buoy 1850 through an air injection pipe 1866, thereby tending to raise the pressure of the air within the buoy. The air pressure control system controls and energizes the air pump 1864 via a cable 1867.
The air pressure control system controls, activates, energizes, adjusts, opens, closes, and/or utilizes, an air valve 1868 to release pressurized air 1869 from inside the air pocket (not visible) within the buoy 1850 to the atmosphere by opening the air valve (or to not release pressurized air, e.g., when the air valve is closed), thereby tending to reduce the pressure of the air within the buoy (i.e., when the valve is open). The air pressure control system opens and closes the air valve 1868 via a cable 1870.
The illustrated embodiment 1850 is very similar to the embodiment illustrated in
Such solutes might include, but are not limited to, potentially useful elemental substances such as gold, magnesium, lithium, and uranium. Such solutes might include carbon compounds such as carbon dioxide and carbonic acid. Such solutes might include, but are not limited to, potential elemental pollutants and/or toxins such as cesium, thorium, arsenic, and mercury.
Such solutes might include, but are not limited to, potentially useful chemical substances such as minerals, nitrates, lithium hydroxides, carbonates, and phosphates. Such solutes might include, but are not limited to, potential chemical pollutants and/or toxins such as petrochemicals, plastics, and pharmaceuticals.
Such solutes might include, but are not limited to, potentially useful particulates (e.g., suspensions of particles) such as plankton and phytoplankton (e.g., which might then be fed to a population of fish, crustaceans, and/or other animals or organisms). Such solutes might include, but are not limited to, potential particulate pollutants and/or toxins such as diesel exhaust, and microplastics.
Within a lower portion of the embodiment's buoy 1850, the embodiment illustrated in
The components, constituents, elements, substances, and/or materials, of which the filter material is comprised include, but is not limited to, fibers, filaments, microfibers, threads, strings, cords, granules, grains, particles, bits, nuggets, motes, fragments, chips, flakes, shards, clippings, and/or shavings. The filter material might be macroscopically organized and/or structured in various manners, forms, and/or strategies, that include, but are not limited to, loose aggregates, one or more adjacent mats, one or more adjacent tubes (including, but not limited to, those stacked horizontally, vertically, and/or randomly), one or more approximately spherical balls, and a plurality of interlocking bricks.
Water-reservoir access pipe 1872 has an upper mouth that is fluidly connected to the embodiment's water reservoir 1873 and the filter 1871 therein. Water, absorbent or adsorbent materials, and/or solutions and/or suspensions of absorbent and/or adsorbent materials, may be added to, or removed from, 1874 the interior of the embodiment's buoy 1850 through, and/or via, the upper mouth of water-reservoir access pipe 1872.
Water-reservoir access pipe 1872 has a lower mouth that fluidly connects the embodiment's water reservoir 1873 and the filter 1871 therein to the atmosphere outside the embodiment. Water, absorbent materials, and/or solutions and/or suspensions of absorbent and/or adsorbent materials, may be added to, or removed from, 1875 the interior of the embodiment's buoy 1850 through, and/or via, the lower mouth of water-reservoir access pipe 1872.
The pressure of an air pocket 1876 nominally exceeds the pressure of the atmosphere outside the embodiment, thereby tending to cause a portion of the water within the embodiment's water reservoir 1873 to enter and flow up the water-reservoir access pipe 1872 to a height 1877 that is a consequence of the difference in the pressures of the air inside 1876 and outside the embodiment.
The absorbent and/or adsorbent material may be extracted, removed, and/or harvested, from the embodiment through, and/or via, a water-reservoir access pipe 1872. A ship, platform, and/or other object, vessel, conveyance, and/or vehicle, can insert a hose, tube, and/or pipe, into and through water-reservoir access pipe 1872, or, alternately, can attach and/or connect a hose to the upper and exterior mouth of water-reservoir access pipe 1872, and thereafter and therethrough remove, e.g., by suction within the hose, a portion, if not all, of the filter material 1871 within the embodiment 1850. Nominally, typically, and/or presumably, the filter material extracted will have absorbed and/or adsorbed a quantity of minerals, elements, molecules, chemicals, and/or particulates, from the body of water 1851 on which the embodiment floats. And, after extracting the original, and nominally mineral-rich filter material 1871 from the embodiment, the ship may then refill the lower portion of the interior of the embodiment's buoy 1850 with new, recycled, and/or the same, filter material, e.g., the same filter material might be reinserted into the embodiment's buoy following the extraction of any targeted minerals from the extracted filter material.
As the embodiment is moved up and down by waves passing across the surface 1851 of the body of water on which the embodiment floats, water entrained within its inertial water tube 1852 tends to oscillate. The water 1877 within the inertial water tube 1852 is shielded from a substantial portion of the wave motion outside the inertial water tube. And, the lower mouth 1853 of the inertial water tube tends to be at a depth near, at, or below, a wave base of the water 1851 on which the embodiment floats. As the water 1877 within the inertial water tube 1852 oscillates and/or moves up and down in response to wave action at the embodiment, water tends to move 1854 in and out of the lower mouth 1853 of the inertial water tube 1852, and the surface 1878 of the water within the inertial water tube 1852 tends to move 1879 up and down. Occasionally, water within the inertial water tube 1852 moves upward within the inertial water tube fast enough, and to a great enough height, that a portion of it escapes 1880 the upper mouth 1881 of the inertial water tube, thereby tending to fall into, and/or be deposited within, an upper portion of the water reservoir 1873, e.g., a portion of the water reservoir above an upper surface 1885, extent, and/or portion, of the filter 1871, and thereby tending to increase the volume of water therein, and tending to compress the air within the air pocket 1876.
As the water 1877 within the embodiment's inertial water tube 1852 moves up and down, and/or oscillates, there tends to be a net flow up the inertial water tube, through the upper mouth 1881 of the inertial water tube, and into the water reservoir 1873. There also tends to be a net flow of the water within the water reservoir 1873 down, through the filter 1871 therein, and out of effluent pipe 1856. Thus, though the motion of the water within the inertial water tube 1852 tends to be oscillatory, there tends to be a net flow into the embodiment's water reservoir 1873, and then back out of the embodiment. The circular flow of the water (into and then out of the embodiment) tends to be energized, and/or driven, by the energy, motion, and/or action, of the waves that move the embodiment.
The water 1877 within the embodiment's inertial water tube 1852 tends to move up and down and/or to oscillate in directions approximately parallel to a flow-parallel longitudinal axis of the inertial water tube. However, when the embodiment is buffeted by a sufficiently vigorous wave climate, then with respect to a period and/or interval of three or more wave periods, there is nominally, and/or tends to be, a net flow of water from the body of water 1851 on which the embodiment floats into the inertial water tube 1852 through the lower mouth 1853 of the inertial water tube. Similarly, when the embodiment is buffeted by a sufficiently vigorous wave climate, then with respect to a period and/or interval of three or more wave periods, there is nominally, and/or tends to be, a net flow of water 1877 from the interior of the inertial water tube 1852 through the upper mouth 1881 of the inertial water tube and into the water reservoir 1873.
The pressure of the air pocket 1876 above the water reservoir 1873 tends to push and/or force water near the upper surface 1873 of the water reservoir to flow 1882 downward and into and through the filter 1871. As the water is forced to flow down through the filter 1871, the filter tends to absorb and/or adsorb one or more specific, desirable, and/or targeted, species, varieties, types, and/or categories, of solutes, elements, molecules, chemicals, and/or particulates, within the water, thereby tending to trap those solutes within the filter 1871.
After flowing through the filter 1871, water flowing down through the water reservoir 1873, flows 1883 through a grating 1884, screen, permeable and/or porous barrier, and/or filter, and thereinto the hollow annular chamber, tank, and/or enclosure inside the annular collar 1855, after which it flows 1857 out through the mouth 1858 of effluent pipe 1856 thereby tending to generate a lateral thrust which tends to propel the embodiment across the surface 1851 of the body of water on which the embodiment floats and in a direction substantially opposite the direction of the effluent discharge 1857.
The embodiment includes, incorporates, and/or utilizes, an air pressure control system (not visible within a control chamber 1861 attached to an outer upper surface of the buoy 1850) that is able to pump air from 1865 the atmosphere into 1886 the pressurized air pocket 1876 within the buoy when it is necessary or advantageous to raise the pressure of the air within that air pocket. The embodiment's air pressure control system is also able to release air from 1887 within the pressurized air pocket 1876 within the buoy and into 1869 the atmosphere when it is necessary or advantageous to reduce the pressure of the air within that air pocket.
The embodiment also has an air pressure-relief pipe 1859 that is fluidly connected to the air pocket 1876 through an upper mouth and to the water 1851 outside the embodiment through a lower mouth. The pressure of the air within the air pocket 1876 tends to force a portion of that air to flow 1889 into and down the air pressure-relief pipe, thereby tending to push down the water that would otherwise rise within the air pressure-relief pipe, e.g., until it reached the height of the surface 1873 of the water reservoir. The level 1888 to which the water within the air pressure-relief pipe is pushed down tends to be determined by, and/or a consequence of, the difference and/or delta of pressure of the air 1876 in the air pocket above the water reservoir, and the pressure of the water 1851 outside the embodiment at the depth of the lower mouth of the air pressure-relief pipe. If and when the pressure of the air within the embodiment's air pocket 1876 exceeds the pressure of the water outside the lower mouth of that pipe then air from the air pocket 1876 will tend to be pushed down, and will tend to flow 1860 out (perhaps tending to create bubbles as illustrated in

The illustrated embodiment 1900 is buoyant and floats adjacent to an upper surface 1901 of a body of water. The embodiment has an approximately radially symmetrical bowl-shaped buoy portion 1902, 1903 at an upper end of the embodiment.

Affixed, attached, included, and/or incorporated within the radial center of the buoy portion is a hollow inertial water tube 1904 with upper 1905 and lower 1906 mouths and/or apertures through which water may move into and out of the inertial water tube 1904.
In response to the passage of waves across the surface 1901 of the body of water on which the embodiment floats at, and/or proximate to, the embodiment, the embodiment tends to move up and down, and water partially trapped, entrained, sequestered, and/or confined, within the embodiment's inertial water tube 1904 tends to move up and down as well, often moving up and down out of phase with, and/or relative to, the embodiment and its inertial water tube. In other words, waves interacting with the embodiment tend to cause the water within the embodiment's inertial water tube 1904 to move and down relative to the embodiment (even while the embodiment is moving up and down).
Occasionally, water moving up and down within the inertial water tube 1904 moves up with enough momentum, energy, speed, and/or to a great enough height, that a portion of that water escapes 1907, and/or is ejected from, the upper mouth 1905 of the inertial water tube. At a first upper constricted portion 1908 of the inertial water tube, the flow-normal cross-sectional area of the tube narrows with respect to a first included angle of the tube wall, thereby becoming increasingly smaller than the flow-normal cross-sectional area of the lower mouth 1906 of the inertial water tube. The narrowing and/or constricted first upper constricted portion 1908 of the inertial water tube has an approximately frustoconical shape.
Above the first upper constricted portion 1908 of the inertial water tube, is a second upper constricted portion 1909, in and/or over which the flow-normal cross-sectional area decreases at a greater rate than that characterizing the first upper constricted portion 1908. The second included angle by and/or at which the second upper constricted portion of the inertial water tube narrows is greater than the first included angle.
The second upper constricted portion 1909 constitutes a nozzle through which ejected water (e.g., seawater) tends to be aerosolized and/or sprayed into the air.
As the embodiment moves up and down in response to the passage of waves, water 1910 within the inertial water tube 1904 moves up and down typically out of phase with the movements of the embodiment. As the water 1910 within the inertial water tube 1904 moves up and down, water tends to flow 1911 into and out of the lower mouth 1906 of the inertial water tube 1904. As the water 1910 within the inertial water tube 1904 moves up and down, an upper surface 1912 of that water 1910 tends to move 1913 up and down. Occasionally, the water 1910 within the inertial water tube 1904 will move up fast enough, with enough momentum, force, and/or energy, to reach and exit the upper mouth 1905 of the inertial water tube, thereby creating an aerosolized spray of water (e.g., seawater).
Buoyancy is provided to the embodiment through an annular ring of buoyant material 1914, e.g., contained within, and/or attached to, the outer wall 1902 of the buoy. Included, incorporated, positioned, stored, encased, and/or trapped, within the interior of the buoy 1902/1903 is a water ballast 1916. And that water 1916, and/or portions thereof, are free to splash out of an annular opening 1915 in the upper surface of the buoy.
Because there is no upper wall covering water ballast 1916, that water ballast, and/or the hollow, chamber, and/or tank, in which the water ballast is positioned, is open to the atmosphere above the embodiment. The level 1917 and/or volume of the water within the water ballast 1916 may be increased by overtopping waves, and ejections of water from the upper mouth 1905 of the inertial water tube 1904. The level 1917 and/or volume of the water within the water ballast 1916 may be decreased as a result of water spilling out during and/or as a consequence of wave induced tilting, as well as due to evaporation.

Airfoil-shaped enclosure 1920/1921 has a flow-normal cross-sectional shape that is similar to that of a wing, i.e., it has aerodynamic qualities that facilitate its movement through water in directions that are approximately parallel to the surface 1655 of the body of water on which the embodiment floats.
Airfoil-shaped enclosure 1920/1921 has a trailing edge 1921 that is approximately positioned beneath the embodiment's overflow aperture 1658, and approximately positioned between the left and right effluent apertures 1656 and 1657. The more bulbous and/or rounded leading edge 1920 of the airfoil-shaped enclosure is oriented toward the direction in which the embodiment would tend to be pushed by the thrust produced by the effluent discharged from the left 1657, right 1856, and overflow 1658, apertures.
The wall, casing, and/or barrier, that defines the shape of the airfoil-shaped enclosure 1920/1921 includes an upper portion comprised, at least in part, of upper walls 1923 and 1924 which prevent the contents of the airfoil-shaped enclosure from escaping the enclosure through the top of the enclosure. Similarly, the wall, casing, and/or barrier, that defines the shape of the airfoil-shaped enclosure 1920/1921 includes a lower portion comprised, at least in part, of lower walls 1925 and 1926 which prevent the contents of the airfoil-shaped enclosure from escaping the enclosure through the bottom of the enclosure.
The inertial water tube has an unobstructed lower mouth 1653 and an unobstructed upper mouth 1659. In response to waves acting at and/or against the embodiment, water 1655 from outside the embodiment enters the inertial water tube 1652 through its lower mouth 1653, moves upward through the channel within the inertial water tube, is ejected from the inertial water tube through its upper mouth 1659, and enters into the water reservoir within the embodiment's hollow flotation module 1651. Thereafter, water from the water reservoir flows out through the embodiment's left or right effluent pipes and respective water turbines, generating electrical power, and returns to the body of water 1655 from whence it came.
The airfoil-shaped enclosure 1920/1921 is attached to, connected to, and/or integrated with, a portion of the wall of the inertial water tube 1652/1667/1660 positioned between the lower mouth 1653 of the inertial water tube and the embodiment's annular collar 1654.
A forward chamber 1927, void, and/or space, is formed at the leading side of the airfoil-shaped enclosure 1920/1921 and is positioned, bounded, and/or enclosed, at least in part, by the leading (blunt) side 1920 of the airfoil-shaped enclosure and the leading side (“leading” with respect to the nominal direction of the embodiment's motion through the body of water on which it floats) of the inertial water tube 1652.
A trailing chamber 1928, void, and/or space, is formed at the trailing side of the airfoil-shaped enclosure 1920/1921 and is positioned, bounded, and/or enclosed, at least in part, by the trailing (edged and/or shape) side 1921/1922 of the airfoil-shaped enclosure and the trailing side (“trailing” with respect to the nominal direction of the embodiment's motion through the body of water on which it floats) of the inertial water tube 1652.
The forward 1927 and trailing 1928 chambers are filled with water so that they are substantially neutrally buoyant.

The embodiment includes, incorporates, and/or utilizes, a substantially hollow, buoyant capsule, and/or flotation module 1950 that tends to float adjacent to an upper surface of a body of water (not shown). Depending from the buoyant capsule 1950 is an inertial water tube 1951 that possesses upper (not visible) and lower 1952 mouths through which water may enter and exit the inertial water tube. Water tends to move into the inertial water tube through its lower mouth 1952 and then flow up the tube and thereafter flow out of, and/or be ejected from, the upper mouth (not visible) of the inertial water tube, thereby entering a water reservoir (not visible) within the buoyant capsule 1950. Also depending from the buoyant capsule 1950 is an effluent pipe 1953 that directs water exiting the embodiment's water reservoir (not visible) through a water turbine (not visible) into the interior of the inertial water tube 1951, with one consequence being that at least a portion of the effluent is likely to again flow up and out of the inertial water tube 1951, and again enter the embodiment's water reservoir.
The embodiment 1950 floats adjacent to an upper surface 1954 of a body of water over which waves tend to pass. As a consequence of, and/or in response to, wave action at and/or against the embodiment water tends to flow 1955 in and out of a lower mouth 1952 of the embodiment's inertial water tube 1951.
A pocket of air, and/or an air pocket, 1956 is trapped within an upper portion of the interior of the embodiment's buoyant capsule 1950, and that air pocket tends to be compressed and/or at a greater pressure than the air outside the embodiment. A pool and/or reservoir, and/or a water reservoir, 1957 is trapped, held, cached, positioned, stored, contained, and/or encased, within a lower portion of the interior of the embodiment's buoyant capsule 1950.
As the embodiment, and the surface 1954 of the water outside and surrounding the embodiment, move up and down in response to the action, impact, passage, and/or movement of waves across the surface 1954 of the body of water on which the embodiment floats, water 1958 inside the embodiment's inertial water tube 1951 tends to move and/or oscillate, e.g., 1959, in directions that tend to be approximately parallel to a nominally vertical longitudinal axis of the inertial water tube. Even though the water 1958 within the inertial water tube 1951 tends to oscillate, there also tends to be a net and/or average flow of water upwards within the inertial water tube.
Oscillations of the water 1958 within the inertial water tube tend to frequently, regularly, periodically, and/or occasionally, cause water from within the inertial water tube to be ejected 1960 from the upper mouth 1961 of the inertial water tube 1951, trapping that water in the embodiment's water reservoir 1957 and thereby preventing that water from reentering and flowing back into the inertial water tube. The frequent, regular, periodic, and/or occasional, ejections of water from, and/or out of, the upper mouth 1961 of the inertial water tube 1951, remove water from the inertial water tube 1951, and water from outside 1954 the embodiment tends to flow into the inertial water tube through its lower mouth 1952 thereby replacing the water ejected from the upper mouth 1961. The frequent, regular, periodic, and/or occasional, ejections of water from, and/or out of, the upper mouth 1961 of the inertial water tube 1951, and the replacement of that water with additional water from outside 1954 the embodiment, results in a net and/or average upward flow of water 1958 within the inertial water tube.
Water flowing 1960 into the water reservoir 1957 tends to raise the surface 1962 of the water reservoir and thereby compress and/or pressurize the air pocket 1956 located above the water reservoir. Water 1957 from the water reservoir, pressurized by the air within the air pocket 1956, tends to flow into an upper mouth and/or aperture 1963 of a water turbine housing and/or pipe 1964 in which a water turbine 1965 rotates in response to the influx of water into the water turbine housing 1964. After flowing through the water turbine 1965 water from the water turbine housing 1964 continues flowing 1966 down and through effluent pipe 1953.
Water 1967 flowing 1966/1968 through effluent pipe 1953 eventually flows 1969 through a lower mouth and/or aperture 1970 of effluent pipe 1953 and flows into the inertial water tube 1951. A portion of water flowing out of the effluent pipe 1953 and into the inertial water tube 1951 will tend to join the water 1958 in its wave-induced oscillations. A portion of water flowing out of the effluent pipe 1953 and into the inertial water tube 1951 might tend to remain, at least for a moment, localized within a portion and/or part of the inertial water tube 1951 adjacent to the lower mouth 1970 of the effluent pipe 1953, and thereabout move up and down, and/or oscillate, 1971 in unison with the rest of the water 1958 within the inertial water tube.
As water is ejected 1960 from the upper mouth 1961 of the inertial water tube 1951, and the water within the inertial water tube 1951 is pulled upward, the ejected water is replaced by both water drawn through the lower mouth 1952 of the inertial water tube 1951 and water discharged by the water turbine 1965 and guided into the inertial water tube through effluent pipe 1953, and the net and/or average upward flow of water within the inertial water tube continues. A portion of effluent water flowing out of the effluent pipe 1953 and into the inertial water tube 1951 will tend to initially become localized, e.g., in the region of 1971, adjacent to the lower mouth 1970 of the effluent pipe 1953, and, as the net and/or average flow of the water 1958 within the inertial water tubes moves upward in response to ejections 1960 from the upper mouth of the inertial water tube, the portion of effluent water originally localized in the region of 1971 will tend to move upward, e.g., 1959, within the inertial water tube until it is proximate 1972 to the upper mouth 1961 of the inertial water tube, and thereafter is once again ejected 1960 from that upper mouth 1961 and back into the water reservoir 1957.
As water flows over the lip and/or edge of the upper mouth 1963 of the water turbine housing 1964 and to and through the water turbine 1965, the water turbine is made, caused, and/or induced, to rotate about the longitudinal axis of its turbine shaft 1973, thereby rotating that turbine shaft and energizing the operatively connected generator 1974, thereby generating electrical power.
Positioned above the upper mouth 1961 of the inertial water tube 1951 is a conical water diverter 1975 that tends to, at least to a degree, laterally disperse water ejected in a nominally vertical and/or upward direction from the upper mouth of the inertial water tube.
This embodiment is well suited for various aquaculture applications, e.g., the raising of microalgae, macroalgae, and fish, because many of the organisms that escape the embodiment's water reservoir 1957 will tend to flow up the inertial water tube 1951 and to be ejected 1960 back into the water reservoir.
An embodiment of the present disclosure similar to the one illustrated in
Water ejected 1960 from the upper mouth of the inertial water tube 1951 collects in the embodiment's water reservoir 1957. Portions of that water flow 1976 into the upper mouth and/or aperture of the water turbine housing 1964, thereafter flowing through the water turbine 1965, and energizing the operatively connected generator 1974 thereby resulting in the generation of electrical power. Water flowing out of the water turbine 1965 flows down, e.g., 1966 and 1968, through effluent pipe 1953 whereafter it flows 1969 into the inertial water tube 1951.
Portions of water that flow 1969 out of the effluent pipe 1953 and into the inertial water tube 1951 tend to remain, collect, mingle, and/or oscillate 1971 with water proximate and/or adjacent to the lower mouth (1970 in
A portion of the water discharged by the water turbine 1965 tends to be recaptured within the inertial water tube 1951 and returned to the water reservoir 1957 to again pass through the water turbine 1951.
When an upper surface 2009 of the water 2000 within the embodiment's water reservoir, spills over 2001, and/or flows into, the upper mouth 2002 of the embodiment's effluent pipe 2003 (which is shown vertically sectioned so as to reveal the water turbine inside). As water flows 2001 into the mouth 2002, and/or into the upper portion, of the effluent pipe 2003 its flow is obstructed, at least to a degree, by water turbine 2004. The flowing water imparts rotational kinetic energy to the water turbine 2004 causing it to rotate 2010, which causes the water turbine's turbine shaft 2005 to rotate, which, in turn, causes the operatively connected generator 2006 to generate electrical power, at least a portion of which is then transmitted through electrical cable 2007 to another part of the embodiment, e.g., to a network of computing devices or light-emitting devices.
After passing through and energizing the water turbine, the water that flowed 2001 into the effluent pipe's upper mouth 2002, continues flowing 2008 through the effluent pipe 2003 until it is discharged from, and/or out of, the embodiment, e.g., returning to the body of water on which the embodiment floats.

In any of the above cases, the conduit or effluent pipe upstream of the turbine can include a converging (e.g. Venturi) section, and in any of the above cases, the conduit or effluent pipe downstream of the turbine can include a diverging/expanding (e.g. Venturi) section.
The water turbine 2020 is operatively connected to a generator 2026 by a shaft 2027, and rotation of the water turbine causes rotation 2031 of the turbine shaft 2027 which, in turn, causes the generator to generate electrical power, and/or an electrical voltage, a portion of which is then transmitted to another part of the embodiment by electrical cable 2028. In a similar embodiment, electrical cable 2028 also permits the embodiment's control system to adjust, control, set, change, and/or alter, the magnitude of the resistive torque applied by the generator 2026 to the water turbine 2020, thereby altering both the amount of electrical power that generator 2026 generates (with respect to a given rate of water turbine rotation), and the degree to which the water turbine inhibits the flow of water into 2033 and through 2029 the effluent pipe 2022 and/or the rate at which the water reservoir 2023 drains.

An embodiment of the current disclosure includes, incorporates, and/or utilizes a water turbine may be characterized as a fixed-pitch propeller.
The scope of the present disclosure includes embodiments that include, incorporate, and/or utilize, any type, variety, class, category, and/or style of water turbine. The scope of the present disclosure includes embodiments that include, incorporate, and/or utilize, water turbines of any size, orientation, and/or relative position within the embodiment, as well as water turbines fabricated of any materials.
The embodiment includes, incorporates, and/or utilizes, a substantially hollow bowl 2050 to which is attached and/or incorporated an annular buoyancy ring 2051 comprised of buoyant material. The hollow bowl 2050 has a bowl lip 2052 that defines a bowl mouth and/or aperture through which the interior of the bowl is fluidly connected to the exterior of the embodiment and through which water ejected by an intra-bowl mouth (not visible) of the embodiment's inertial water tube 2053 can flow 2054 through the bowl mouth and escape the embodiment, at least for a moment.
The bowl lip 2052 of the embodiment is formed by, and/or constitutes, an open and/or distal edge of a concave portion 2055 of the wall and/or hull of the bowl. Below the concave portion 2055 of the bowl is a convex portion 2050 about which the annular buoyancy ring is attached, connected, and/or incorporated. And below the convex portion 2050 is an approximately frustoconical portion 2056. The nominally upper concave portion, the nominally middle convex portion, and the nominally lower frustoconical portion, together constitute the hollow bowl 2050, 2055, 2056.
Effluent from the inertial water tube's water discharges flows 2057 out of the embodiment through effluent pipe 2058.
As the embodiment is moved by passing waves, water tends to move and/or flow 2059 in and out of an extra-bowl mouth positioned at an end of the inertial water tube 2053 that is opposite that of the intra-bowl mouth (not visible).
An upper mouth is defined by bowl lip 2052 said bowl lip being at an upper end of concave bowl portion 2055. Inside the hollow, void, chamber, space, and/or compartment within the interior of the hollow bowl 2050/2052 is a first constricted portion 2061 of the embodiment's inertial water tube. And, at the uppermost end of the inertial water tube is a second constricted portion 2062, and at the upper end of that second constricted portion is an upper, and/or intra-bowl, mouth 2063 through which water is occasionally ejected from the inertial water tube.
Adjacent to the bottom of the interior of the hollow bowl 2050/2052 is a flat bottom wall and/or surface 2064 and penetrating that flat bottom wall is the upper mouth of an effluent pipe 2058.
As the embodiment is moved up and down by waves passing along the surface 2060 of the body of water on which the embodiment floats, water 2065 within the embodiment's inertial water tube 2053 tends to move up and down relative to that tube, tending to cause water to move 2059 into and out of the lower mouth 2066 of the inertial water tube, and also tending to cause an upper surface 2067 of the water 2065 within the inertial water tube to move up and down, and occasionally causing that surface to be projected 2054, lifted, elevated, and/or ejected, beyond and/or outside of the upper mouth 2063 of the inertial water tube. A portion of the ejected water tends to fall back into, and become trapped within, the interior of the hollow bowl 2050/2056, wherein the body of such trapped discharges of water form a water reservoir 2068 having an upper surface 2069. A portion of the ejected water may travel outside and/or above the upper mouth 2075 of the hollow bowl 2055/2050, thereby potentially escaping the embodiment and returning to the environment outside the embodiment.
Water moving upward within the inertial water tube 2053 from the tube's lower mouth 2066, initially flows through a lower tube portion 2053 characterized by an approximately constant flow-normal cross-sectional area, e.g., an approximately cylindrical portion. The water then flows through a lower constricting portion 2061 where the progressively decreasing flow-normal cross-sectional area tends to increase the speed at which the water flows upward, e.g., through that portion of the inertial water tube and relative to the speed at which it flowed upward through the lower cylindrical portion 2053. The water then flows through a relatively short tube portion 2070 that is, like the lower tube portion 2053, also characterized by an approximately constant flow-normal cross-sectional area, e.g., an approximately cylindrical portion. And, finally, the water flows through an upper constricting portion 2062 where the progressively decreasing flow-normal cross-sectional area tends to further increase the speed at which the water flows upward, e.g., through that portion of the inertial water tube and relative to the speed at which it flowed upward through the both the lower cylindrical portion 2053 and the middle cylindrical portion 2070.
Because the interior of the hollow bowl 2050/2055 is open to the atmosphere, and not pressurized beyond that of the atmosphere, the average height of the upper surface 2067 of the water 2065 within the embodiment's inertial water tube 2053/2061/2070/2062 will tend to be at least approximately equal to the height of the water 2060 on which the embodiment floats.
At least a portion of the water ejected 2054 from the upper mouth 2063 of the inertial water tube 2053 tends to fall into, and be captured within, the water reservoir 2068. Water from the water reservoir 2068 tends to flow 2057 into an upper mouth 2071 of effluent pipe 2058, flow through the effluent pipe, and then flow 2057 out of a lower mouth 2072 of the effluent pipe, thereby returning to the body of water 2060 on which the embodiment floats.
The upper mouth 2071 of effluent pipe 2058 is and/or constitutes an aperture within a bottom plate 2064. If the embodiment illustrated in
The interior of the embodiment's annular void 2073 beneath bottom plate 2064 may be filled with water, e.g., in order to add mass to the embodiment. It may be filled with a buoyant material (e.g., foam, air, or wood) in order to promote the buoyancy of the embodiment. It may be filled with a negatively buoyant material in order to decrease the buoyancy of the embodiment.
The interior 2074 of the embodiment's annular buoyancy ring 2051 is comprised, at least in part, of a structural foam that is buoyant. An embodiment of the present disclosure that is similar to the one illustrated in
The embodiment 2100 floats adjacent to an upper surface 2101 of a body of water over which waves tend to pass. The embodiment 2100 is the same embodiment illustrated in
Also attached to the embodiment's upper platform 2104 is a phased array antenna 2105 that facilitates the exchange of encoded radio transmissions 2126/2127 between the embodiment and antennas connected to, and/or controlled by, other objects, including, but not limited to: satellites 2128, ships, planes, balloon-suspended transceivers, and/or terrestrial transceivers, computers and networks.
At least a portion of the electrical power generated by the embodiment, and/or extracted by the embodiment from the ambient wave environment, is used to energize at least a portion of the electronic circuits positioned, stored, and/or protected within, the computer enclosure 2103 and the embodiment's phased array antenna 2105.
At least a portion of the electrical power generated by the embodiment, and/or extracted by the embodiment from the ambient wave environment, is used to energize autonomous underwater vehicles (AUV), e.g., 2106.
A tether 2107, cable, conduit, and/or circuit, connects the embodiment 2100 at connector 2108 to a submerged, and approximately neutrally buoyant AUV hub 2109, and is supported, at least in part, by a plurality of floats, e.g., 2110. Tether 2107 transmits electrical power to the AUV hub 2109 which is shared with AUVs when those AUVs, e.g., 2106, couple and/or dock with the AUV hub. Tether 2107 also transmits data between the embodiment's computing devices and/or control system (not shown) and docked AUVs.
AUV hub 2109 is connected to a weight 2111 that promotes the stability of its orientation. AUV hub 2109 contains a number, e.g., 4, docking ports, e.g., 2112-2114, each of which contains acoustic, visual, and magnetic signals and/or guides, e.g., a speaker and microphone 2115 that emits a click of a specific frequency in response to a click of generated by the speaker 2116 of an AUV, e.g., 2117. The clicks exchanged between the AUV hub 2109 and the various AUVs that it supports, e.g., 2106, are simulations of clicks generated by whales and/or other marine cetaceans.
Each AUV cooperating and/or interacting with the illustrated embodiment 2100 is propelled by a propeller, e.g., 2118 and 2119 on AUVs 2106 and 2117, respectively. The orientation and direction of each AUV cooperating and/or interacting with the illustrated embodiment 2100 is controlled by a plurality of fins, e.g., 2120 and 2121 on AUVs 2106 and 2116, respectively. Each AUV cooperating and/or interacting with the illustrated embodiment 2100 contains a camera, light, and acoustic generator (speaker), e.g., 2122 on AUV 2116.
Each AUV's acoustic generator is able to generate a simulated whale click (or other sound), e.g., 2123, that can be directed to reflect off the seafloor 2123, e.g., at 2125, or another surface, and thereafter be received, heard, and/or detected, by the respective AUV's microphone 2116 (2116 is a microphone and speaker). By determining the time required for the generated acoustic signal 2123 to be reflected and subsequently detected by microphone 2116, the AUV can determine the approximate distance between the AUV's speaker 2122 and the portion of the seafloor, e.g., 2125, that gave rise to the reflection. When combined with measurement of the depth-related water pressure of the AUV, the depth of the seafloor, e.g., at 2125, may be determined, at least to an approximate degree, thereby permitting a mapping of the terrain, depth elevations, etc. of those portions of the seafloor so surveyed.
Analysis of the reflected AUV acoustic signal may also signify information about the composition and/or density of the material at the reflecting surface(s). The AUV's camera and light 2122 can potentially produce images of the seafloor, and/or other objects of interest, e.g., of the same portion of the seafloor 2125 depth-ranged by the AUV's acoustic generator and microphone.
Though the illustrated embodiment 2100 generates electrical power solely in response to wave motion, the scope of the present disclosure includes embodiments similar to the one illustrated in
The embodiment 2150 floats adjacent to an upper surface 2151 of a body of water over which waves tend to pass. The embodiment 2150 is the same embodiment illustrated in
Also attached to the embodiment's upper platform 2154 is a phased array antenna 2155 that facilitates the exchange of encoded radio transmissions between the embodiment and antennas connected to, and/or controlled by, other objects, including, but not limited to: satellites 2156, ships, planes, balloon-suspended transceivers, and/or terrestrial transceivers, computers and networks.
Also attached to the embodiment is an autonomous underwater vehicle (AUV) 2157.
At least a portion of the electrical power generated by the embodiment, and/or extracted by the embodiment from the ambient wave environment, is used to energize at least a portion of the electronic circuits positioned, stored, and/or protected within, the computer enclosure 2153 and the embodiment's phased array antenna 2155.
At least a portion of the electrical power generated by the embodiment, and/or extracted by the embodiment from the ambient wave environment, is used to energize autonomous underwater vehicles (AUV), e.g., 2157.
Attached to a lower portion of the embodiment 2150, e.g., to a lower portion of the embodiment's inertial water tube 2158, at 2159, is a tether 2160, cable, conduit, tube, and/or multi-stranded wire, that is, at least in part, supported and/or suspended within the body of water 2151 by a plurality of floats, e.g., 2161, that offset the positive wet and/or specific weight of the tether and tend to impart to the tether an approximately neutral buoyancy.
Directly connected to a lower end of the tether 2160, at connector 2162, is a remotely-operated vehicle (ROV) 2157. The embodiment's ROV 2157 is propelled by four propeller-thrusters, three 2163-2165 are visible in the illustration of
The embodiment's ROV 2157 has two cameras 2166 and 2167 with overlapping fields of view allowing stereoscopic analysis of the images taken which may then permit, at least partial, 3D models to be constructed of the objects and/or surfaces so imaged. The embodiment's ROV 2157 also has an upper 2168 and a lower 2169 acoustic sensors, each capable of generating, and receiving and/or detecting, sounds (e.g., simulated whale clicks). These acoustic sensors provide the ROV 2157 with the ability to detect distances to other objects and/or surfaces.
The embodiment's ROV, among other uses, may provide sufficient information and/or data to permit the embodiment to map the depths of the seafloor 2170, and/or its surface contours. The lower acoustic sensor 2169 on the embodiment's ROV 2157 can generate a sound 2171 and thereafter detect its reflected echo, thereby allowing the ROV 2157 to gauge the distance between that sensor and the seafloor 2170 beneath the ROV, allowing that distance to be calculated, at least to an approximate degree. The ROV also incorporates a pressure and/or depth sensor that allows it to determine its depth, at least to an approximate degree. By combining these two distances, i.e., the distance between the ROV's lower acoustic sensor 2169 and the seafloor 2170, and the depth of the ROV, and the distance between the surface 2151 of the body of water on which the embodiment floats and the seafloor 2170 can be calculated, at least to an approximate degree, thereby permitting, as the embodiment moves across the surface 2151 of the body of water and the seafloor below, the mapping of the elevations and/or depths of portions of the seafloor overpassed by the embodiment and/or its ROV.
A tube-mounted acoustic sensor 2172, attached to the embodiment's inertial water tube 2158, is capable of generating sounds 2173 that can reach 2174 the ROV 2157 and be detected by its upper acoustic sensor, e.g., 2168. Since the embodiment's control system (not shown) knows the time at which the sound was emitted, as well as the time at which it was received by the ROV, the embodiment can calculate, at least to an approximate degree, an “acoustic distance” between the embodiment's tube-mounted acoustic sensor 2172 and the ROV's 2168 upper acoustic sensor. The embodiment's tube-mounted acoustic sensor can be a combination of a speaker and hydrophone.
The embodiment possesses stereoscopic cameras, and other sensors, mounted to an upper portion of the buoy 2150 that allow it to calculate the height of its own waterline, and/or the draft or depth of its inertial water tube 2158. Subtracting this tube depth from the ROV depth determined by the ROV's pressure and/or depth sensor (not shown) permits the embodiment to determine the “tube-relative depth” of the ROV relative to the bottom of its inertial water tube 2158 and/or to the tube-mounted acoustic sensor 2172 mounted thereto.
If the value of the tube-relative depth equals the acoustic distance, then the ROV must, at least to an approximate degree, be directly beneath the tube 2158 and/or the tube-mounted acoustic sensor 2172. However, if the value of the tube-relative depth is greater than the acoustic distance, then the ROV's position must be within a horizontal plane (i.e., within a plane parallel to the resting surface 2151 of the body of water on which the embodiment floats), and on a circle centered about a projection of a vertical axis passing through the tube-mounted acoustic sensor 2172. Thus, the position of the ROV must be, at least to an approximate degree, on such a circular path. This enables the embodiment's control system (not shown) to make adjustments to the ROV's position (e.g., through commands to the ROV 2157 causing the ROV to execute specific thrust vectors relative to its own longitudinal axis and/or geometry) and note the corresponding changes in the diameter of the circular path on which the ROV must be positioned.
Through trial and error, and/or in combination with data from accelerometers on the buoy 2150 and ROV 2157, GPS receiver(s) on the buoy 2150 and/or within its computer enclosure 2153, differential times at which ambient underwater noises are detected by the tube-mounted acoustic sensor 2172 and one or both of the ROV's acoustic sensors 2168 and 2169, and/or other position-sensing instruments, mechanisms, devices, and/or sensors, the embodiment's control system can steer its ROV with thrusts of magnitudes and orientations that cause the ROV to follow the movement of the embodiment's buoy 2150 across the surface 2151 of the body of water on which the embodiment floats (regardless of whether that movement is passive, i.e., drifting, or directed, e.g., via self-propulsion) and/or to stay beneath the embodiment's inertial water tube 2158, at least to an approximate degree.
While the embodiment illustrated in
The embodiment 2200 floats adjacent to an upper surface 2201 of a body of water over which waves pass. The embodiment contains a buoyant, and/or buoy, portion 2200 and a depending tubular portion 2202, i.e., an inertial water tube, and is the same embodiment illustrated in
Also attached to the embodiment's upper platform 2204 is a phased array antenna 2205 that facilitates the exchange of encoded radio transmissions 2206/2207 between the embodiment and antennas connected to, and/or controlled by, other objects, including, but not limited to: satellites 2208, ships, planes, balloon-suspended transceivers, and/or terrestrial transceivers, computers and networks. The phased array 2205 is able to both transmit 2206 and receive 2207 encoded electromagnetic (e.g., radio) signals.
At least a portion of the electrical power generated by the embodiment, and/or extracted by the embodiment from the ambient wave environment, is used to energize at least a portion of the electronic circuits positioned, stored, and/or protected within, the computer enclosure 2203 and the embodiment's phased array antenna 2205.
At least a portion of the electrical power generated by the embodiment, and/or extracted by the embodiment from the ambient wave environment, is used to energize autonomous underwater vehicles (AUV), e.g., 2209 and 2210, via and/or by means of a hub 2211.
Connected by cable, chain, linkages, rope, and/or another flexible connector 2212, is a spar buoy 2213. Discordant motions between the buoy 2200 and the spar buoy 2213 are smoothed, buffered, and/or absorbed, by an elastic mooring device 2214, comprised of a pair of floats, e.g., 2214, beneath which is suspended between the floats a weight 2215. Separations of buoy 2200 and the spar buoy 2213 cause the floats, e.g., 2214 to separate, which, in turn, causes the suspended weight 2215 to be raised, thereby storing potential energy. The stored potential energy pulls back together the buoy 2200 and the spar buoy 2213 when the, presumably wave-driven, forces separating the buoys is sufficiently diminished.
Cable 2212 transmits power and data between computers in computing enclosure 2203 and spar buoy 2213, and cable 2216 in turn transmits at least a portion of that power and data between spar buoy 2213 and an autonomous-underwater-vehicle (AUV) hub 2211. Thus, power and data are exchanged between the embodiment 2200 and/or the electronic circuits within computing enclosure 2203 and the AUV hub 2211. A plurality of floats, e.g., 2217, help to support the weight of the cable and allow it to achieve approximate neutral buoyancy.
The AUV hub 2211 has a number of thrusters, including a fixed horizontal-thrust thruster 2218, four circumferential thrusters, e.g., 2219, that are arrayed about the long horizontal axis of the AUV hub 2211, and are able to be rotated about the rods that rotatably-connect them to the hub. The AUV hub 2211 also includes a single thruster that ejects water 2220 vertically through one of an upper 2221 or lower 2222 mouth (while pulling water through the opposing mouth).
The AUV hub 2211 has three docking ports, e.g., 2223 and 2224, positioned circumferentially about a horizontal plane passing through the center of the AUV hub. At the center back wall of each docking port is a light and acoustic sensor, e.g., 2225, that provides guidance information and/or signals to the AUVs that dock therein.
The AUV hub includes a camera and light 2226 that can provide images of the seafloor 2227 and/or AUVs, e.g., 2228.
Each AUV, e.g., 2228, of the embodiment 2200, has four cameras, and associated lights. Two cameras and lights, e.g., 2229 and 2230, are mounted on back-facing struts, and tend to provide useful information to an AUV when it attempts to insert its back end, e.g., 2210, into a docking port, e.g., 2224, on the AUV hub 2211. The back-facing cameras of an AUV provide it with stereoscopic images, which, in combination with the homing signals emitted by the light and acoustic sensor, e.g., 2225, at the back inside of each docking port, can facilitate the insertion of an AUV, e.g., 2211 into a docking port, e.g., 2224.
Two cameras and lights, e.g., 2231 and 2232, are mounted on front-facing struts, and tend to provide useful information to an AUV when it attempts to survey, inspect, and/or gather information about the seafloor 2227, objects thereon, e.g., 2233, and/or other objects, creatures, and/or surfaces. The AUV 2228 is attempting to pick up a geological sample 2233 from the seafloor 2227. After obtaining a sample, e.g., 2233, from the environment, an AUV 2210 and/or the embodiment's central control system (e.g., positioned within the embodiment's computing enclosure 2203), may elect to store that sample 2234 for later examination by a human, and/or within a ship- or shore-based laboratory, by placing it within a receptacle, e.g., 2235, and logging the time and geospatial location at which the sample was obtained, along with any photos taken by the AUV's cameras, e.g., 2231 and 2232, of the sample prior to and/or after its retrieval, and the identifier of the receptacle in which the sample was stored.
A set of sample receptacles, e.g., 2236, are suspended by a cable 2237 that depends from a spar buoy 2238 that is flexibly connected to the embodiment 2200 by a cable 2239, wherein said cable includes an elastic mooring device 2240 to more flexibly connect the embodiment 2200 and spar buoy 2238 when the positions of both are buffeted by passing waves. Each sample receptacle, e.g., 2236, contains an aperture, e.g., 2241, through which an AUV may place a sample therein.
Each AUV, e.g., 2209, contains an articulating arm, e.g., 2241, rigid segments of which rotate about rotating joints so as to allow the orientation and position of a grasping claw and/or gripper, e.g., 2242, to be adjusted through a range of such orientations and positions. Each AUV, e.g., 2209, also contains four thrusters, e.g., 2243-2245, the thrusts of which may be adjusted through the rotation of each thruster about the longitudinal axis of the respective rod that connects each thruster to the main body of the AUV.
After docking with a docking port, e.g., 2224, on the AUV hub 2211, an AUV may obtain electrical power from the embodiment 2200, the electronic circuits (which may include energy storage devices) inside the embodiment's computing enclosure 2203, and/or from the embodiment's generators (not shown) and/or energy storage devices (not shown), thereby enabling it to recharge its own energy storage devices and/or mechanisms (not shown).
Embodiments similar to the modified embodiment illustrated in
As the embodiment 2050 moves up and down in response to passing waves, water 2065 within its inertial water tube 2053 tends to move up and down relative to the embodiment and the inertial water tube. As the water 2065 within the inertial water tube 2053 moves up and down, water moves 2059 in and out of the lower mouth (2066 in
Water flows 2059 in and out of the lower mouth of the inertial water tube through the gaps, e.g., 2078, between the structs, e.g., 2077, by which the flow diverter is attached and/or connected to a lower end of the inertial water tube.
Flow diverter 2076 can be filled with a material more dense than the water on which the embodiment floats, and that material includes, but is not limited to, cement, iron, gravel, sand, rocks, and other cementitious materials. An embodiment similar to the one illustrated in
Flow diverter 2076 tends to provide the illustrated embodiment with additional ballast that tends to help it to remain vertically oriented. Flow diverter 2076 also tends to buffer the impact of vertical oscillations of the embodiment, e.g., during storms, on the vertical oscillations of the water 2065 within the inertial water tube 2053, thereby helping to protect the structural integrity of the embodiment, e.g., during storms.
