Transportation System Overview
Referring to
Some elements of a high-speed transportation system are discussed in Hyperloop Alpha, a white paper authored by Elon Musk, which includes some structural and system examples, the entire content of which is expressly incorporated by reference herein in its entirety.
In an exemplary and non-limiting embodiment of the present disclosure, a system comprises one or more partially evacuated tubes 14 that connect, for example, stations 16 in a closed loop system. In other contemplated embodiments, the system may include a one-way connection between an origin and a destination. In embodiments, tubes 14 may be sized for optimal air flow around the capsule 12 to improve performance and energy consumption efficiency at the expected or design travel speed. In accordance with aspects of the disclosure, the low-pressure environment in the tubes 14 minimizes the drag force on the capsule 12, while maintaining the relative ease of pumping out the air from the tubes.
In embodiments, the capsule may be levitated over a track using a pressurized fluid flow (e.g., air or liquid) exiting out, e.g., a bottom side of the capsule and interacting with the corresponding track. In further contemplated embodiments, the capsule may be levitated using, for example, passive magnetic levitation (e.g., mag-lev), with, for example, non-superconducting magnets. In certain embodiments, the capsule may be levitated using rockets, wings, aerodynamic (control) surfaces, ion engines, electromagnets, and/or slipper pads. Additionally, the capsule may include one or more permanent magnets. e.g., in a Halbach array on the capsule, which interact with a passive, conducting track to levitate the capsule. By utilizing passive magnetic levitation, a high lift-to-drag ratio can be achieved, which results in a very low power consumption. Moreover, in accordance with some aspects of the disclosure, the efficiency of the passive (e.g., permanent) magnetic levitation system may increase (at least in some respects) as the vehicle speed increases. Other embodiments may utilize superconducting magnets for levitating the capsule.
By implementing aspects of the present disclosure, the capsules are operable or available on-demand, which further enables an on-demand economy. For example, in embodiments, capsules may depart a station as (e.g., launched in a tube of the transportation system), as frequently as every ten seconds. In such a manner, for example, the capsules are operable or available on-demand. Implementing aspects of the present disclosure, will, in embodiments, cause a transformation of cities and will unlock real estate values, and will have the ability to reshape shipping and logistics industries, for example. Additionally, implementing aspects of the disclosure will profoundly impact human behavior and human interaction with the Earth, and will reduce transportation and shipping pollution.
While embodiments of the present disclosure are directed to using a low-pressure environment, in some contemplated embodiments, the environment may be at atmospheric pressure (i.e., not a low-pressure environment), which may be easier to maintain as compared to a low-pressure environment. For example (and as discussed in more detail herein), with some shorter travel distances (for example, short enough that the capsule may not easily attain a high speed before needing to slow down again), it may be more efficient to run the system in an environment that is at atmospheric pressure to, for example, reduce costs of maintaining a low-pressure environment. For example, if a travel route is only 30 km long, the capsule may not be able to achieve its top speed (due to relatively short distance of the route). In such embodiments, the disclosure contemplates that it may be unnecessary to reduce the operating pressure of the environment below atmospheric pressure.
In accordance with aspects of the disclosure, in embodiments, the pressure of the environment may be, by design, operating at a uniform pressure (e.g., a uniform low pressure). The inventors contemplate, however, that embodiments of the disclosure may include different regions of the tube that are operating at different pressures (e.g., two different low pressures). For example, a section of tube may be maintained at normal pressure for loading a capsule. Once the capsule is loaded, an airlock may be closed and the tube section may be depressurized to the low pressure of the transportation system, after which another air lock is opened, and the capsule is sent along a path of the transportation system. Aspects of airlocks and gate valves for a high-speed transportation system are discussed in commonly-assigned U.S. application Ser. No. 15/007,712, filed in the USPTO on even date herewith, the content of which is expressly incorporated by reference herein in its entirety.
The capsules are transported at both low and high speeds throughout the length of the tube and may be supported on a cushion of pressurized air with aerodynamic lift or may be levitated with rockets, wings, aerodynamic (control) surfaces, ion engines, electromagnets, slipper pads, permanent magnets (e.g., a Halbach array), or superconducting magnets, for example. In some embodiments, the capsule may also be supported (e.g., intermittently) on wheels. As discussed in more detail herein, it is understood that numerous other mechanisms and environments may be provided to accomplish the aims of the disclosure.
In accordance with aspects of the disclosure, the capsules, elements of the tube, and the track are able to communicate with each other so as to, for example, control a capsule traveling within the tube and/or control operating conditions of the tube or track. As one example, spacing between capsules within the same tube may be maintained using autonomous vehicles that are aware of the other capsules' relative location. By autonomous, it should be understood that the vehicle is not driven by an operator on the vehicle, but is operated using at least one computerized controller. Thus, if a vehicle ahead on the tube path has slowed (e.g., due to a malfunction), then other capsules upstream of the slowed capsule may include sensors to detect, recognize, and analyze such a situation, and may slow the velocity of the upstream capsules. As another example, the capsules may be in communication with a central command (which is aware of the location and speed of each capsule in the system), and receive an instruction from a central control to slow the velocity of the capsule if a capsule in front of said capsule is moving too slowly. As a further example of communication between elements of the system in order to control operating conditions, during a seismic event, portions of a tube that detect the seismic activity (e.g., are closer in proximity to the epicenter of the seismic activity), may communicate with portions of the tube further from the epicenter to adjust operating conditions of the tube and/or tube support structures (e.g., thermal expansion joints, or vibration dampening elements) to account for the seismic activity.
In embodiments, should there be a loss of communication between capsules themselves, or between the capsules and the track or tube, for example, the transportation system (or portions thereof) may shut down, and for example, let air pressure into the low-pressure environment of the tube so as to assist in deceleration of the capsules. That is, by removing or reducing the low-pressure environment in the tube (e.g., bringing the pressure to atmospheric pressure), the capsules will encounter greater air resistance, which will cause the capsules to slow down. In embodiments, the capsules may each be equipped with onboard emergency power systems sufficient to provide auxiliary propulsion to the capsule (e.g., to propel the capsule (or cause the capsule to crawl) to the next station or to an emergency egress) in the event of an emergency (e.g., loss of low-pressure environment). Additional emergency measures may include a pathway, for example, adjacent the track, as a walkway for passengers, should exit from the capsule be necessary. The emergency walkway may include lighting to assist the debarked passengers in navigating the emergency walkway, and may also include an airflow (e.g., oxygen) system to provide breathable air to the debarked passengers. In embodiments, areas for passenger egress outside the tube may be provided, for example, in the event of a failure or emergency.
Referring now to
As depicted in the exemplary embodiment of
With an exemplary and non-limiting embodiment, a capsule 12 may be configured to carry eight people, and in another non-limiting embodiment, a capsule 12 may be configured to carry eighty people. In accordance with aspects of the disclosure, smaller capsules (e.g., those configured to carry 8 passengers), will not need as long to be loaded and reach their capacity, which allows such capsules to be sent more frequently, as soon as they are loaded. In such a manner, with smaller capacity capsules, the capsules are able to be dispatched in an on-demand manner. In contrast, with a capsule configured to carry 80 people, for example, it may take more time for the capsule to be filled to capacity, which may necessitate that some passengers wait a longer period of time before departing. In accordance with aspects of the disclosure, with a larger-capacity capsule, however, the capsules may not need to be sent as frequently.
Passengers may enter and exit the capsule at stations (for example, as depicted in
In an alternative embodiment of the disclosure, the capsule is configured to allow the transportation of a payload, such as materials or goods, e.g., automobiles, cargo containers, along with passengers between locations. With such embodiments, the inventors contemplate embodiments having separate loading stations for the passengers and the cargo. That is, the cargo may be loaded into a capsule (e.g., first) at a cargo loading station. Once the cargo containing region of the capsule is filled, the capsule may be directed to a passenger loading area, from where the passengers may enter the capsule. In such a manner, the passengers who have boarded the capsule need not wait for cargo to be loaded, as the cargo has already been loaded prior to passenger boarding.
In yet a further contemplated embodiment, for example as depicted in the exemplary embodiment of
For example, in those embodiments in which the capsule is only transporting, for example, non-human cargo, the capsule may not be restricted (or may be less restricted) in the speeds it travels through the tube. As a capsule moves through a path that is bending (or turning), the contents of the capsule will be subjected to increased G-forces. When the contents of the capsule include humans (or other animals), the capsule speed may be reduced in such bending paths to reduce the degree of G-forces experienced by the passengers. Non-human cargo, however, may be less impacted by increased G-forces, and in such embodiments, it may be unnecessary to slow a capsule carrying non-human cargo during bending paths (or a capsule may be slowed to a lesser extent than would a human-carrying capsule). Additionally, with such embodiments in which the capsule is only transporting, for example, non-human cargo, the capsule may not need the same level of safety mechanisms (e.g., life support systems) that would be utilized with a human-carrying capsule.
In embodiments, the capsules may be configured (or constructed) with spaces designated for accommodating cargo so that the cargo is more likely to sustain the expected G-forces. Such designated spaces should be designed to maintain the cargo or other payload in its loaded positions, so that during travel of the capsule, the cargo and/or payload and objects inside the capsule are prevented from moving. As should be understood, if the cargo were to move (or be shifted) during travel, such movement could upset the balance of the capsule, and detrimentally impact travel of the capsule.
In accordance with further aspects of the disclosure, a cargo or payload orientation tester may be used to test (or measure) a loaded capsule (e.g., with cargo and/or other payload, including passengers) to ensure the capsule is properly loaded (e.g., properly balanced), and provide an indication (e.g., alert) when the cargo-loaded capsule is not properly (e.g., evenly) loaded. For example, for much of the travel distance along the tubes, the capsules are gliding and may be free to relatively rotate around its longitudinal axis in the tube (for example, as turns in the tube are traveled). If the capsule is not properly or sufficiently balanced, this rotation of the capsule may become too extreme to maintain a comfortable traveling experience. Scales and attached sensors and alarms can be provided to measure the weight and/or balance (e.g., weight distribution in the capsule) and provide an alert when necessary.
In accordance with additional aspects of the disclosure, in embodiments utilizing both human-carrying capsule (or pods) and cargo-containing capsules, these respective capsules may be sized differently, and in embodiments, may utilize separate track systems and tubes, which are each optimized for the respective capsules.
As shown in
In accordance with aspects of the disclosure, the compressor allows the capsule to traverse the relatively narrow tube 14 without impeding air flow that travels between the capsule and the walls of the tube. For example, operation of the capsule 12 through the tube 14 may result in a build-up of air mass in front of the capsule 12, which may increase the drag coefficient and/or detrimentally affect capsules ahead of the current capsule. The compressor is operable to compress air that is bypassed through the capsule 12. That is, instead of the oncoming air being passed around the capsule 12, in certain embodiments, the compressor is operable to ingest at least a portion of the oncoming air, which is passed through a passageway provided in the capsule, so as to reduce drag on the capsule 12. In exemplary and non-limiting embodiments, the compressor ratio of the compressor may be 30/1, may be 4/1, or may be somewhere within this range. In further embodiments, the capsule may not include an onboard compressor at all.
The compressor may also operate to supply air to, e.g., a bottom side of the capsule 12 to air bearings, which provide a cushion of air to support the weight of the capsule throughout the journey. In further embodiments, a capsule may utilize wheels, for example, during an initial acceleration (e.g., at lower speeds, when the air bearings and lift are not sufficient to levitate the capsule) and/or during emergencies. As discussed in more detail herein, in some embodiments, wheels may be arranged at a fixed height that will engage a track only when the air bearings (or other levitation system) are not sufficient to lift the wheels off the tracks. In other contemplated embodiments, the wheels may be deployable from a recessed position.
In accordance with aspects of the disclosure, the capsule 12 may be accelerated via a magnetic linear accelerator or linear motor (e.g., a linear synchronous motor (LSM) or a linear induction motor (LIM)) affixed at various locations along the low pressure tube (e.g., at stations and/or at selected locations along the tube) with rotors contained in or on each capsule 12. Aspects of the linear motors are discussed in commonly-assigned application Ser. No. 15/007,940, entitled “Continuous Winding For Electric Motors,” and commonly-assigned application Ser. No. 15/008,024, entitled “Dynamic Linear Stator Segment Control,” both filed with the USPTO on even date herewith, the contents of which are hereby expressly incorporated by reference herein in their entireties.
Rotors are located on the capsules to transfer momentum to the capsules via the linear accelerators. In embodiments of the present disclosure, a moving motor element or rotor is located on the capsule that cooperates with the stator or stationary motor elements located on the track that drive the capsule. The stator is structured and arranged to locally guide and accelerate and/or decelerate the capsule.
The linear accelerators are constructed along the length of the tube at various locations to accelerate the capsules. That is, in accordance with aspects of the disclosure, the linear accelerators may not be located along the entire track (e.g., from point A to point B), but only in discrete segments. As the capsule is operating in a low-pressure environment, once accelerated, the capsule will travel a significant distance before losing significant speed (for example, the capsule may travel 100 km before losing 10% of its initial speed). As such, once accelerated, the capsule may only need intermittent speed boosts (provided by the discrete segments of linear accelerators (e.g., LSMs or LIMs)) as the capsule travels from point A to point B.
In other exemplary embodiments, the capsule 12 may be accelerated (and decelerated) using one or more of: jet thrust, a turbofan, a turboprop, a propeller, hydraulic cylinders, pneumatic cylinders, cables, fluid, fluid jets, and/or thermal gradients.
Referring now to
In such embodiments, use of pillars (or supports) 22 to support the tubes 18, 20 of the transportation system provides numerous benefits. In embodiments, the pillars 22 may include one or more dampers to adjust for lateral and/or vertical forces or displacements (e.g., due to forces caused by the capsule movement, thermal considerations, or seismic events). Tubes 18, 20 need not be fixed to the pillars 22, but can instead be fixed to a dampening system that is supported by pillars 22. The pillars 22 and the dampening system are structured and arranged to constrain the tubes 18, 20 in a vertical direction while allowing longitudinal slip for thermal expansion as well as dampened lateral slip. Some embodiments may also allow for some movement in the vertical direction between the pillars 22 and the tubes 18, 20, and/or between the pillar and the ground. In addition, in accordance with aspects of the disclosure, the position of the pillar-to-tube connection may be adjustable vertically and/or laterally, for example, to ensure proper alignment of the tube, and to provide for a smoother ride. In another embodiment of the present disclosure, slip joints may be provided at each station to adjust for tube length variance due to, for example, thermal expansion.
In accordance with aspects of the disclosure, by arranging the transportation tubes over land (e.g., above-grade) or within the land (e.g., below-grade), the need for grading can be eliminated or reduced. Additionally, above-grade tubes can more easily cross natural barriers. For example, bridges may be less expensive, for example, due to low mass per capsule, and tunnels may be less expensive, for example, due to a tube's resistance to external pressure. Additionally, arranging the transportation tubes over land (e.g., above-grade) or within the land (e.g., below-grade) may present fewer barriers to construction (e.g., easy to obtain rights-of-way (or ROW)). In embodiments, the tubes may reach city centers, for example, above-grade or via a tunnel below-grade.
Alternative Tube Locations
Referring now to
Generally vertical/up and down movement of the capsule (e.g., to change elevation to rise over hills or mountains) is more difficult to achieve than a left and right movement of the capsule. Thus, in accordance with aspects of the disclosure, by locating the transportation system over (or in) a body of water, transportation paths having significant changes in elevation can be avoided (or reduced).
In accordance with additional aspects of the disclosure, in embodiments, the tube 14 may be constructed of materials such that the state of the tube may be naturally buoyant, neutrally buoyant, or naturally sinking in the water. With an exemplary embodiment, the tube is naturally very buoyant, and may include counterweights to achieve neutral buoyancy. Additional embodiments may utilize anchors, spar-buoys, and/or tension lag platforms to assist in maintaining a position and/or orientation of the tube in the water. In further contemplated embodiments, the tube 14 may have different buoyancy characteristics along different portions of the tube 14. For example, different portions of the tube 14 may comprise different materials, different construction, and/or different thicknesses to provide different buoyancy characteristics along different portions of the tube 14. Buoys 26 may be adapted to the physical state of the tube 14 to ensure that the tube remains in a generally static position.
Buoys 26 may be configured in a variety of ways to accomplish aims of the present disclosure. As shown in
In the exemplary and non-limiting embodiment of the present disclosure shown in
It should also be understood that the buoys 26 may also be configured to support a serve purpose to the support structure 28. For example, as depicted in
In one exemplary and non-limiting embodiment of the present disclosure, each joint 36 allows relative angular movement of one tube 14 relative to its adjacent tube 14 within one or more predetermined angles of deflection θ. It should be understood that the one or more predetermined angles of deflection θ should be determined so that too great an angle between adjacent tube sections 14 is prevented. That is, as the capsule travels the tube 14, if the angle of deflection between adjacent tube sections is too great, then, for example, the passengers may be subjected to very high G-forces as the capsule passes this deflection angle. As such, in accordance with aspects of the present disclosure, the amount of deflection between adjacent tube sections 14 may be limited to a maximum deflection angle θ. In embodiments, the maximum deflection angle θ may be determined based on, for example, capsule design speed and type of cargo (e.g., human cargo, non-human cargo, or non-living cargo).
As shown in
In embodiments, the tube may be above land (e.g., suspended off the ground over land or water), on land (e.g., on the surface of land or water), below ground, and/or below the surface of the water. In accordance with aspects of the disclosure,
In embodiments, upon reaching the maximum deflection angle θ, the joint 36 may be temporarily locked (e.g., for a short period) at this maximum deflection angle θ before allowing the affected tube sections 14 to “unbend” toward a linear alignment. In embodiments, the “unbending” of the affected tube sections 14 may be slowed. For example, the forces (e.g., tidal forces) acting on tube sections 14 may cause two tube sections to deflect relative to one another, which will cause the joint 36 to bend. Assuming with this example, that the joint 36 was bent to its maximum deflection angle θ, upon a subsiding of the forces (e.g., tidal forces), which otherwise might allow the tube sections to return to their fully aligned state, the joint 36 remains at the maximum deflection angle θ for a period of time (e.g., 15 seconds), and then released (e.g., slowly). In accordance with aspects of the disclosure, by delaying and/or slowing the release of the angular orientation of the joint 36 (e.g., from the maximum deflection angle θ), sudden changes in the tube direction may be avoided. In certain embodiments, the delayed and/or slowed unbending may be utilized when a capsule is approaching or within the joint 36 bent at the maximum deflection angle θ.
In embodiments, the transportation system may be configured to shut down (e.g., temporarily), to slow the speeds of capsule in the system, or to stop sending additional capsules into the system should, for example, the body of water be experiencing extreme turbulence (e.g., large waves) that may cause high levels of tube movement. For example, sensors and or GPS information may be configured and/or utilized to detect extreme conditions (e.g., larger than normal waves, impactful weather) and actively control, for example, portions of the transportation system to adjust for the conditions. Such sensors may include, e.g., accelerometers, gyroscopes, and/or optical sensors. Such active controls may include, for example, slowing the capsule in the immediate area of the disturbance, as well as adjusting speeds of upstream capsules. The capsules may be slowed, for example, by controlling the propulsion systems to not provide acceleration to a passing capsule, deploying capsule braking systems (e.g., passive electromagnetic braking) or deploying a deceleration device. Examples of braking devices are also disclosed in commonly-assigned U.S. application Ser. No. 15/007,718, entitled “Deployable Decelerator,” filed in the USPTO on even date herewith, the content of which is hereby incorporated herein by reference in its entirety. In additional embodiments, the active controls may include looking ahead along the travel path and adjusting the speed there through and/or adjusting alignment of the tube sections. The system may utilize the communication capabilities of the tubes and/or capsules to send and/or receive instructions for adjustments to the speed there through and/or adjustments for alignment of the tube sections.

In accordance with aspects of embodiments of the present disclosure,
Off-Shore Loading/In-Land Port
As shown in the exemplary embodiment of
Conventionally, ships sailing into port will line up in a queue extending well offshore and await their turn to unload (and/or load) their cargo. This results in a seemingly perpetual queue of cargo ships extending from the port out into the sea, which creates an eyesore and pollution close to shore. By implementing the aspects of the present disclosure, however, the offloading of cargo may be conducted at a distance d from the port. In embodiments, the distance d may be, for example, fifteen miles. In accordance with aspects of the disclosure, by locating the platform 52 away from shore, the queue of cargo ships will not be viewable from shore (or may be less viewable), thus reducing the eyesore of cargo ships, and reducing pollution closer to shore. In accordance with further aspects of the disclosure, by locating the platform 52 away from shore, efficiencies for cargo transfer can be increased.
As discussed above, with embodiments of the present disclosure, the cargo ships no longer need to travel all the way into the port area 890 to offload or on-load cargo. With this in mind, by utilizing aspects of the present disclosure, the location of the “port” itself (e.g., the location of the off/on loading equipment (e.g., manned and/or autonomous or semi-autonomous equipment), such as cranes, the cargo container storage areas, and the on/off loading equipment to load the removed cargo onto other types of vehicles (e.g., trucks and/or trains) for downstream distribution) may be moved to a location remote from the coastline. That is, as the cargo ships no longer have a need to travel all the way to the shoreline, there is an opportunity to relocate the infrastructure of the “ports” to an inland location, thus freeing up the coastline areas previously utilized as the shoreline port, for other development opportunities (e.g., residential or commercial real estate). Thus, as shown in
Further contemplated embodiments of the tube transportation may utilize the high-speed tube transportation system to move cargo beyond the port infrastructure area (e.g., situated on the coastline or at a remote location) to one or more downstream destinations (e.g., a final destination, an airport, or some other transportation hub). In such embodiments, cargo may be off-loaded from a cargo ship at an off-shore docking area, and placed in capsules for transport for a high-speed transportation system. In contrast to the above described embodiment, the transport of the capsules containing the cargo from the off-shore docking area to the port infrastructure area may be through lower speed transportation tubes, e.g., using a different propulsion system and/or an un-evacuated transportation tube. Upon arrival at the port infrastructure area, the capsules may be moved (or otherwise directed) from the lower-speed transportation tube to a high-speed transportation tube. By utilizing these aspects of the disclosure, the off-loading (and on-loading of cargo) and the movement of the cargo containers to vehicles for transport to a downstream (e.g., final) destination can be accelerated by utilizing a common transport vehicle (i.e., the capsule) to move the cargo through multiple phases (e.g., off the ship and out of the port area) of the cargo-transit route. In further contemplated embodiments, a high-speed transportation system may originate at a port infrastructure area itself (e.g., without utilizing an off-shore docking area or connection thereto). Such a high-speed transportation system may provide tube transportation paths to one or more downstream destinations (e.g., a transportation hub, a factory, a final destination).
In-Situ Manufacturing
Referring back to
In embodiments of the present disclosure, the tube may be manufactured in-situ, wherein, for example, raw material(s) are fed-in and composite tube structure is built on location. With one exemplary and non-limiting embodiment, an in-situ manufacturing system may produce up to 1 km of 2-way tube per day, per machine, with other production rates contemplated by the disclosure.
In a further exemplary and non-limiting embodiment, as depicted at 900′ in

In an exemplary and non-limiting embodiment, the apparatus includes a material bender configured to bend a tube wall material into a cylinder shape, and a welder configured to weld a seam between ends of the tube wall material to form the tube. The apparatus may additionally include one or more of: a foundry configured for manufacturing wall material; and a roller configured for rolling the tube wall material to achieve a uniform wall thickness for the tube wall material.
In certain embodiments, the manufacturing the one or more transportation tubes includes forming tube sections of the transportation tube, installing one or more tracks in the tube sections; attaching the tube sections to support structures; and connecting adjacent tube sections to one another to form the transportation tube.
It is also contemplated that pillars 22 may be either prefabricated or in-situ manufactured and incorporate additives and/or support elements, such as dampers, reinforcement members and the like, for example, as discussed herein, to improve the physical characteristics of the pillars 22. In the exemplary embodiment shown in
As shown in
In the exemplary embodiment shown in
It is possible that optimization of the thickness of the tube 14 to withstand the forces expected within tube 14 (e.g., caused by the capsule as it traverses the tube 14) is not sufficient to prevent undesirable downward deflection forces on tube 14, due to the weight of the tube 14 between pillars 22. Thus, by utilizing a support structure 70, the tube 14 itself can be optimized for the forces expected within the tube (e.g., caused by the capsule as it traverses the tube 14), while the thickness of the support structure 70 is optimized to prevent any significant deflection of the tube 14.
Tube Structures and Manufacturing
The operation of the capsule within the tubes of the transportation system benefits from the inner layer of the tube being configured in order to obtain maximum performance and efficiency. One or more embodiments of the present disclosure discussed below provide solutions to this challenge not only for purposes of the transportation system, but also for other industry applications, including, for example, the oil and gas pipeline industry and the like. Additionally, while the tube structures are configured for transporting the capsules, the tubes may also be configured for accommodating, for example, third party cable and/or wiring systems. In accordance with aspects of the disclosure, by additionally utilizing the tubes for third party cable and/or wiring systems, the costs for constructing and/or maintaining the tube transportation system can be defrayed or shared. In other words, the right of way (ROW) of the transportation path may be monetized for placement of, for example, electricity, communications wiring, and/or pipeline that can be installed in or on the tubes of the transportation system.
Referring now to
As shown in
The material of the fill layer 78 may be a foam material (e.g., very heavy foam, such as a metal foam, or some other suitably-stiff frame material, such as a honeycomb or pyramidal structure) which is utilized to provide stiffness (in contrast to, or in addition to, strength) to the tube construction. Furthermore, the foam material may be optimized to provide thermal and/or acoustic insulation. By forming the tube with a fill layer 78, the costs of tube manufacturing may be reduced, as the overall thickness of the steel layers is reduced (as compared to a uniform steel tube thickness of the same diameter). Moreover, by utilizing a fill layer 78 of lower weight (as compared to the other materials of the tube wall), such as a foam, the entire weight of the tube section may be reduced, while providing a tube having the same (or similar) strength and/or stiffness properties.
While the depicted exemplary embodiment illustrates three layers, in embodiments the tube construction may include more than three layers. For example, a tube may include more than one “inner” layer and/or more than one “outer” layer. Additionally, the tube may include an additional middle metal layer and an additional fill layer between the middle metal layer and either the inner wall or the outer wall, thus providing a metal-fill-metal-fill-metal laminate construction.
In one exemplary and non-limiting embodiment of the disclosure, the inner wall 80 is expanded through a loading process, such as, for example, internal pressure to create a tensile state 84 in the inner wall 80. Next, the outer structure 82 is secured to inner wall 80 as the loading process is ended, creating a net compression state 86 in the outer structure 82. In this state, the inner wall 80 remains in tension, and thus provides a stable support surface for the outer structure 82.
In another embodiment of the present disclosure, the inner wall 80 may be expanded through a heating process (instead of or in addition to the internal pressure), causing the inner wall to elongate. With an exemplary embodiment, temperatures up to or exceeding 200° F. may be used during this heating process. The combined inner wall 80 and outer structure 82 are cooled after the heating process is ended when the outer structure 82 is secured to the inner wall 80. This process provides similar results to the mechanical loading process described above, such that the inner wall 80 is in tension 84 while the outer structure 82 is in compression 86.
In accordance with aspects of the disclosure, in this state, the induced tension load 94 causes the outer wall 92 of tube 88 to create an equivalent pressurized stabilized structure in a net tensile state. In embodiments, capsules (or pods) may 12 travel on each side of the compression member 90 within the tube 88. By implementing these aspects of the disclosure, the tube wall thickness may be decreased, thus requiring less material and resulting in reduced costs for tube construction. Additionally, by implementing a net tension tube, less expensive tube wall materials may be sufficient to provide the necessary strength and/or stiffness for the tube, thus requiring less material and resulting in reduced costs for tube construction.
In accordance with additional aspects of the disclosure,
Alternatively, tube configurations may be the same for both land and sea usage (e.g., over water or under water). That is, it is possible to use the same tube configuration as the tube path travels over land (or underground) and over water (or underwater). In further contemplated embodiments, a tube path may comprise multiple tube configurations at different regions of the tube path.
While many of the exemplary depicted embodiments of the tube configuration are circular in cross-section, other cross-sectional shapes (e.g., oval, rhombic, rectangular) may be used. For example, while a circular cross-sectional shape provides a tube that is in uniform compression (or, in embodiments, in tension), the tube configuration may also be based (for example, at least partially) on aesthetic considerations in addition to structural or design considerations.
Furthermore, while many of the depicted exemplary embodiments of the tube are uniform in wall thickness, it is possible that the tube wall may be variable in thickness. For example, in regions of the capsule travel path subjected to higher G-forces (e.g., in turns or bends in the path), the thickness of the tube may be increased. Alternatively, the tube wall can be thickened around the entire circumference of the tube, or the tube wall thickening may be located around only portions of the circumference of the tube (e.g., the wall portions towards which the vehicle will be driven to due centrifugal forces acting on the vehicle as it traverses past a curve in the transportation path). Conversely, in other embodiments, the thickness of the tube may be decreased in regions of the capsule travel path subjected to lower G-forces (e.g., in straighter portions in the path).
In accordance with additional aspects of the disclosure, the tube wall thickness may be optimized for the anticipated capsule speeds and/or to assist in controlling the capsule speeds. For example, in embodiments, a tube wall thickness may be increased so that the inner diameter of the tube 14 is reduced. As the inner diameter of the tube 14 is reduced, the flow passage for air around the capsule 12 is also reduced. In accordance with aspects of the disclosure, by reducing the air flow passage around the capsule 12, drag on the capsule 12 is increased, and the capsule 12 is slowed. Tube wall thickness can also be increased so that the inner diameter of the tube 14 is reduced in regions of the transportation system where slowing of the capsule is desired, e.g., approaching a station, or a significant curve or turn in the transportation path.
In further contemplated embodiments, portions of the tube may include windows (or at least partially translucent materials) and the capsule itself may include windows (or at least partially translucent materials). By providing such windows in the tube and capsule, a passenger will be able to “see” outside of the transportation system, which may, for example reduce feelings of claustrophobia, and provide passengers a similar experience to that of traveling on a train (e.g., of viewing the surrounding environment as the capsule traverses the tube path). Utilizing at least partially translucent materials will, for example, allow a passenger to at least view incoming light from outside the tube. Such clear or partially translucent materials may include, for example, graphene and/or carbon reinforced materials (e.g., similar to sailboat sails). Additional alternative structures for low-pressure environments, which can be used in lieu of the tubes, are discussed in commonly-assigned U.S. application Ser. No. 15/008,017, entitled “Low-Pressure Environment Structures,” filed in the USPTO on even date herewith, the content of which is expressly incorporated by reference herein in its entirety. Any of such low-pressure environment structures could be used instead of and/or with the tubes, and include (but are not limited to) materials which can withstand a tensile load.
In other contemplated embodiments, the capsule may include viewing screens (e.g., LCD or LED screens) which provide a view of the outside environment as the capsule traverses the tube transportation path. In embodiments, cameras may be utilized to acquire images (e.g., in real time) of the outside environment, which are then projected on the viewing screens in the capsule. In other contemplated embodiments, the viewing images can be predetermined (e.g., pre-recorded), so as to project a standard depiction of the outside environment (e.g., not a real time display) as the capsule traverses the tube transportation path.
Levitation Systems and Method
For example, as shown in
As shown in
With exemplary track configuration 1700, two tracks 100 are provided extending from the tube 14 at approximately 45° angles relative to vertical, respectively. In embodiments, the tracks 100 may be welded and/or fastened to the inner wall of the tube 14. The capsule 12 has corresponding air (or other) bearings 102 structured and arranged to interact with the two tracks 100. In accordance with aspects of the disclosure, by utilizing track configuration 1700, the two tracks 100 provide additional horizontal stability by providing balancing horizontal force vectors.
With track configuration 1705, three tracks 100 are provided extending from the tube 14, with one track 100 extending from beneath the capsule (as with the embodiment of
With track configuration 1710, a single track 100′ is provided extending from the tube beneath the capsule (as with the embodiment of
With track configuration 1715, two tracks 100″ are provided extending from the tube 14 at approximately 90° angles relative to vertical. As shown in
As shown in
Track Switching
While the exemplary embodiments have been described as traveling, for example, from point A to point B, the disclosure contemplates that having single tubes between destinations will rapidly increase system cost and create bottle necks at major transportation hubs. Additionally, it may be difficult to change routes using air bearings that utilize a circular hull to ride on. Thus, there is a need for an effective technique to switch between different routes within the transportation system.
With embodiments of the present disclosure, as shown in exemplary
In embodiments, the presently disclosed track switching systems may be designed for optimal loading scenarios on the capsule. In accordance with aspects of the disclosure, by designing the track switching systems for optimal loading scenarios on the capsule, the switching time can be greatly decreased.
In further embodiments, for example as schematically depicted in
Additionally, as shown in the exemplary depiction of a switching system of
In accordance with aspects of the disclosure, utilizing these moveable walls allows for the use of air bearings and maintains the integrity of the inner hull of the tube for the pod to ride on. Moreover, should the flapper door fail to properly actuate, the capsule can still travel down the incorrect path (e.g., the non-desired path). In embodiments, should the flapper door 2255 fail to actuate properly, such that the flapper door 2255 is in a position preventing passage down either path, one or more sensors (not shown) may detect the improper position, and halt (or slow) an approaching capsule until the flapper door 2255 is properly positioned.
While
For example, the capsule may utilize three air bearings 102 and corresponding tracks 100, for example, as depicted in configuration 1705 of
As shown in the embodiment/schematic depiction of
As should be understood, should it be desired to send the capsule 12 along downstream path 2245, the right-side actuatable track 2285 would be moved beyond an interaction region of the right-side bearing 102, and the left-side actuatable track 2285 would be moved into an interaction region of the left-side bearing 102. As shown in
In accordance with further aspects of the disclosure, a track configuration may change along a path of travel, for example, for “turning” the capsule when a track diverges into two separate paths. For example, in embodiments, the tubes may include one or more tracks having different functions, such as moving the capsule to different routes by the combination of a top and bottom track. In one exemplary and non-limiting embodiment, if a top track is used as a primary mode of capsule movement, when a switching region (or switching station) is encountered, a bottom track may be provided for a portion of the capsule movement, which supports the weight of the capsule while the top track is switched to the appropriate track to follow. In further embodiments, it is also contemplated that rotary bearings (e.g., wheels) may be used (with or without air injection) to provide lift or support for the capsule to accomplish the same aims.
In accordance with aspects of the disclosure, as the capsule 12 continues moving in the travel direction 2420, as schematically depicted in
As shown in
As shown in
As shown in
By implementing these aspects of the disclosure, for example, an upstream bearing is operable to react to a tube protuberance (e.g., a bump, a drop or a gap in the track or tube), and the control loop is operable to signal to other downstream bearings to increase or decrease fluid flow rate (and, in embodiments, a bearing (or ski) angle), accordingly, so as to provide a smoother ride over the protuberance.
In embodiments of the present disclosure, it is contemplated that levitation is accomplished utilizing a phase change of a fluid in the gap between the fixed surface of the track or tube and a surface of the capsule. In accordance with aspects of the disclosure, the act of phase change causes pressure to build between the surfaces of the track and bearing, causing lift. For example, in certain embodiments, a subcooled liquid can be placed into the surface gap, such that the surrounding energy causes vaporization of the subcooled liquid. In certain embodiments, the fixed surface (or track) and/or the vehicle surface (or bearing) can be heated to cause phase change.
In accordance with aspects of the disclosure, the capsule may be propelled (e.g., accelerated and/or decelerated) using linear motors (e.g., LSMs and/or LIMs), having, for example, stator segments arranged along discrete portions of the tube path, that interact with a rotor (or rotors) arranged on the capsule. In embodiments, both the rotor and the stators are arranged within the low pressure environment of the tube. In other contemplated embodiments, the stators or the rotor may be arranged outside of the low-pressure environment.
In the embodiment shown in
By implementing these aspects of the disclosure, that is, by locating tube propulsion elements 2905 (e.g., stators) on an exterior of the tube 14, access to these elements may be much easier, thus improving serviceability of elements (e.g., power or propulsion systems) of the transportation system. Additionally, by implementing these aspects of the disclosure, construction of the tube and/or the tube propulsion elements may be simplified and costs may be reduced. Furthermore, in accordance with aspects of the disclosure, by locating tube propulsion elements on an exterior of tube 14, dissipation of thermal energy can be improved. The tube propulsion elements 2905 (e.g., stators) may generate large amounts of heat. In accordance with aspects of the disclosure, by locating tube propulsion elements 2905 (e.g., stators) on an exterior of the tube 14, for example, as shown in
In accordance with additional aspects of embodiments of the disclosure, by locating tube propulsion elements 2905 (e.g., stators) on an exterior of the tube 14, the location of the coils of the stators may be optimized (e.g., initially arranged and/or repositioned) after construction and/or placement of the tubes. For example, tube propulsion elements 2905 may be disconnected from a current position (e.g., by removing fasteners and/or welds) and repositioned in a new location. Repositioning of the tube propulsion elements 2905 may be undertaken, for example, if it is determined that a current location of the tube propulsion elements 2905 does not achieve the desired capsule velocity in a particular region of the tube. Additionally, by locating tube propulsion elements 2905 (e.g., stators) on an exterior of the tube 14, the placement of the stators may be adjusted or the numbers of stators supplemented to adjust for changing propulsion needs or conditions.
When the tube propulsion elements 2905 (e.g., stators) are located on an exterior of the tube 14, these tube propulsion elements 2905 are no longer within the low-pressure environment 2915 of the tube. As such, in accordance with additional aspects of the disclosure, by arranging at least some of the propulsion elements, e.g., the tube propulsion elements 2905, outside of the low-pressure environment 2915, while elements (e.g., pod elements 2910) within the low-pressure environment 2915 may need to be designed to properly function in the low-pressure environment, tube propulsion elements 2905 (e.g., stators) can be optimized for the ambient environment, which may reduce costs.
In accordance with aspects of the disclosure, by providing a moving stator, the distance-range over which a stator section is operable may be increased. For example, while it should be understood that the schematic depiction of
As shown in the position of
As discussed above, embodiments of the present disclosure may utilize wheels on the capsule. In embodiments, the wheels may be structured and arranged in a “deployed” position, while being selectively spaceable (or distanced) from the track surface (e.g., due to operation of a levitation system). In additional contemplated embodiments, the wheels may be structured and arranged for occasional and/or temporary deployment, for example, from a recessed position.
Temperature Controlled Rail System
Additional aspects of the present disclosure are directed to a temperature controlled rail system. Rail systems for capsules traveling at the designed speeds may involve high thermal loads. Thus, aspects of the disclosure are directed to rail systems and train rail alignment methods, e.g., to a rail structured and arranged to accommodate for thermal expansion by using temperature controlled steel and/or thermo-electrics, for example, arranged within the track structure.
In certain embodiments, as schematically depicted in
In accordance with certain embodiments, it is important to ensure that each component inside the tube expands the same distance and magnitude to thus ensure alignment of all components. In an exemplary embodiment, the tube and track structure may be configured as a multi-layered tube having different components (e.g., steel tube, high precision track, concrete foundation, etc.), all of which may have their own intrinsic thermal expansion coefficient. As a result, different structural components may expand at varying degrees (with some structural components expanding drastically more than others). Expansion offsets can be extremely detrimental to the functionality of the transportation system, increasing the possibility of derailment and other critical failure events.
While railroads combat this issue by having gaps in the track to allow for thermal expansion, that solution does not suitably work in the present transportation system, as the gaps in the track may introduce a detrimental impulse/shock to the pod as it travels over such a gap. While buckling of a rail may not be a main issue, it is very important to take into account, as is dealing with problems resulting from the steel outer hull of the track being more than likely to expand much more drastically than the safety rails or a laminate propulsion or levitation structure.
Active Track Alignment System
Further aspects of the present disclosure are directed to an active track alignment system for the transportation system. Track misalignment, even on small scales, could be detrimental to the transportation system having capsules traveling at high speeds. For example, the effects of small deviations in the track would potentially be amplified by pods (or capsule) when encountered at high speeds.
In accordance with aspects of the disclosure, a track position detection system is configured to measure the deflection and/or deviation of the track, and a track adjustment system is operable to make deflection and/or deviation adjustments to the track in real-time. The track position detection system is configured to measure the deviations from true alignment, which can be caused by various reasons. In accordance with aspects of the disclosure, measurement readings could be taken, manipulated and processed using a control circuit and/or computer processor configured to calculate (e.g., quantify) how far the rails would have to be moved back into place.
The track adjustment system can comprise servo-mechanical systems structured and arranged to move the track back to alignment in accordance with the acquired data (e.g., in real time). In certain embodiments, the actuators may be structured and arranged to push and pull the rails laterally and/or lift and retract the rail vertically, as necessary, for example, to move the rails into proper position.
In certain embodiments, the active track alignment system may be located in the tube transportation system at points of relatively higher need for such adjustments, e.g., regions of higher seismic activity, regions of higher thermal activity, in proximity to track switching locations, along regions of the path subjected to higher G-forces, and/or other forces.
By implementing aspects of the present disclosure, track misalignment can be reduced or eliminated in a real time manner to ensure proper alignment of the rail(s) of the transportation system.
Rotating Pod Re-Orientating Skid
Additional aspects of the present disclosure are directed to a rotating pod re-orientating skid, e.g., a turntable. Slow pod turnover (e.g., the emptying of a pod or capsule in preparation for the pod's next trip) can produce a series of issues, such as but not limited to, decreased operating frequency, minimized profits, and wasted system energy expenditures. In accordance with aspects of the disclosure, a skid is structured and arranged to support a pod as it comes off of levitation rails, e.g., upon reaching location B from location A. The skid rapidly re-orientates a pod for the opposite tube (e.g., tube configured and/or designated for travel from location B to location A), for example, by laterally translating and rotating the pod (or capsule) on a central, vertical axis all while simultaneously loading it into the opposite tube. By implementing aspects of the disclosure, tube turnaround times may be significantly reduced.
In accordance with aspects of the disclosure, the pod can be rapidly prepped for reuse. In one embodiment, for example, as depicted in
Rotating Pod Loading/Unloading System
Further aspects of the present disclosure are directed to a revolver-styled, rotating pod loading/unloading system. As noted above, slow pod turnover (e.g., the emptying of a pod or capsule in preparation for the pod's next trip) can produce a series of issues, such as but not limited to, decreased operating frequency (e.g., decreased outgoing pod frequency), minimized profits, and wasted system energy expenditures.
In accordance with aspects of the disclosure, as schematically depicted in
In such system, a pod (or capsule) can be rapidly prepped for reuse. The rotating capsule loading/unloading system is operable to autonomously load and unload cargo from the capsules, and place the capsules in outgoing/incoming tubes. By implementing such a system, a need for multiple tube entrances may be reduced.
Further aspects of the present disclosure are directed to a system of mechanized cargo conveyor belts for rapid pod resupply. Crane-based cargo loading can be slow which will in turn create longer turnaround time and pod prep time, which can lower profit margins. In accordance with aspects of the present disclosure, a conveyor belt system facilitates the cargo preparation and loading procedures from start (e.g., receiving cargo) to finish (sending outgoing pods) and vice versa. In embodiments, as schematically depicted in
By implementing aspects of the present disclosure, loading the capsules using queued cargo containers on a belt can drastically decrease load times of the capsule, and thus increase outgoing pod frequency, and efficiency of the overall system.
Emergency/Maintenance Personnel Transportation Vehicle
Additional aspects of the present disclosure are directed to a personnel transportation vehicle to be utilized, for example, in emergencies or maintenance. In accordance with aspects of the disclosure, the transportation tube crosses vast swaths of land. As such, maintaining maintenance/emergency stations over a given (e.g., relatively short) distance may not be economically feasible. The farther away these maintenance/emergency stations are from each other, the slower the response time may be to emergencies.
In accordance with aspects of the disclosure, a safety vehicle is operable to ride the levitation rail, for example, for rapid travel to points of interest in tube. The vehicle may be used to carry, for example, maintenance gear, emergency supplies and/or personnel to a particular site within the tube. Such vehicle may be a pod that is configured to carry emergency/maintenance personnel and/or equipment instead of passengers or cargo. The emergency/maintenance personnel transportation vehicle may be arranged in one or more pre-determined locations along the tube (e.g., in auxiliary tube branches dedicated for accommodating and launching the emergency/maintenance personal transportation vehicle), such that it may be deployed from the closest launching branch when an emergency or maintenance issue arises.
In embodiments, the personal vehicles may utilize magnetic levitation (e.g., Halbach array) and/or alternative propulsion systems (e.g., auxiliary on-board propulsion systems). By implementing aspects of the disclosure, the vehicle would greatly increase response times, for example, to emergencies and quickly transport personnel to maintenance hot spots via the tube.
Movable, Tube Based, Circular/Saddle-Like Scaffolding Used in Tube Maintenance/Construction
In the context of the transportation system described herein, further aspects of the present disclosure are directed to a movable, tube based, circular/saddle-like scaffolding, for example, for use in tube maintenance and/or construction environment.
In accordance with aspects of the disclosure, as schematically depicted in
In embodiments, scaffolding system 3600 may be air-lifted, e.g., via connection 3615, and placed directly on tube 14 and fastened thereto, thus providing an instant platform that could be used in a variety of applications, such as maintenance or rescue operations, for example. The scaffolding system 3600 may be attached to the tube, for example, using fabric or metal webbing wrapped and fastened around the tube and/or with fasteners or temporary welds. When tubes 14 are located on the ground any repairs may be easier to carry out. If the transportation tube 14 is suspended high off the ground, however, embodiments of the present disclosure may assist in positioning workers around the tube 14, while providing one or more stable and flat working surfaces 3605. In embodiments, the mobile scaffolding 3600 may also include barriers 3610 to provide protection from the elements (e.g., wind and precipitation). In further embodiments, the mobile scaffolding 3600 may be structured and arranged as a gas enclosure, so as to maintain an operating pressure in the tube 14 while it is accessed to receive maintenance.
Passive Electromagnetic Braking
Aspects of the present disclosure relate to a braking system for high speed vehicles (e.g., capsules), and more specifically to a system that uses electromagnetic drag to slow a vehicle. As discussed herein, a high speed, high efficiency transportation system utilizes a low-pressure environment in order to reduce drag on a vehicle at high operating speeds, thus providing the dual benefit of allowing greater speed potential and lowering the energy costs associated with overcoming drag forces. These systems use a near vacuum (or low-pressure environment) within a tubular structure. These systems may utilize any number of acceleration systems to achieve the high speed allowed, including linear motors, e.g., linear synchronous motors (LSM) and/or linear induction motors (LIM) in conjunction with, for example, electromagnetic levitation or fluid bearings. Due to the scale of the project, tremendous forces are required to accelerate the vehicle to the operating speed. Newton's Laws of Motion dictate that an equal force is necessary to slow the vehicle down when necessary, such as arriving at the terminal at the end of the route. Because of these high speeds, typical braking methods that operate by utilizing friction may be impractical. For example, current practices do not envision a method to create a sustainable frictional braking system designed to handle the immense stress that would be produced by this decelerating force because current transportation systems do not operate at the speeds that a partially-evacuated tubular system allows.
In accordance with aspects of the disclosure, as schematically illustrated in
Passive Levitation System
As discussed herein, high-speed transportation systems may utilize any number of acceleration systems to achieve the high speed, including electromagnetic propulsion. Due to the scale of the transportation project, tremendous forces may be necessary to accelerate the vehicle to the operating speed. Due to the unprecedented nature of the sustained, ultra-high speed configuration of the system, the capsule may utilize a carriage that can withstand the frictional demands of the high-speed and high use.
In one exemplary embodiment, the track 3880 is comprised of at least one section of laminated sheets of slotted conductor, wherein the slots 3890 have a length 3897 that is equal to or shorter than the width 3898 of the associated magnet assembly 3895 on the vehicle 12. In certain embodiments, the slots 3890 may be angled relative to the track 3880 and/or the magnet assembly 3895 in a direction of motion of the vehicle 12. The angle may be perpendicular or an angle more or less than perpendicular, e.g., 88° relative to the position of the track 3880 and/or magnet assembly 3895. In certain embodiments, the magnet assembly 3895 comprises of a plurality of magnets, such as permanent magnets, electromagnets, and/or superconducting magnets, which is configured in an array that optimizes the magnetic force that is generated by the interaction of the array of the magnet assembly 3895 and the track 3880 while in motion. A plurality of tracks 3880 may be used, each with an associated magnet assembly 3895 located on the vehicle 12.
Pre-Fabricated Metal Reinforcement for Pylons
In certain embodiments, the supports (or pylons) may include within a pre-fabricated metal reinforcement, e.g., a chain mail-styled, pre-fabricated metal reinforcement. The pylon construction can be slow, in turn, slowing the rest of fabrication and manufacturing for transportation system. In accordance with aspects of the present disclosure, pre-fabricated rolls of chain mail pylon reinforcement may be rapidly assembled, for example, either before the concrete for the pylons is poured or after the concrete is poured. In some embodiments, metal rods of varying gauge sizes and/or aramid fibers can be fabricated in a cross-stitched pattern and be embedded in cement. By implementing aspects of the present disclosure, the pre-fabricated metal reinforcement material can expedite manufacturing process and provide additional structural support to the sub-structure.
Monitoring Tube Integrity Using Aerial Vehicle
Managing, identifying, and locating leaks in tube system may be very difficult, especially on the size and magnitude of the transportation system. Aspects of the present disclosure are directed to a method for monitoring the transportation tube (or other low-pressure environment) integrity using an aerial vehicle, for example, a remotely-operated aerial vehicle (or drone). In some embodiments, a drone equipped with infrared imaging camera may be configured to fly along the transportation path and searching for thermal plumes (e.g., large thermal plumes) of leaked air. For example, in embodiments, a drone may be configured to autonomously fly the transportation route. Equipped with a FLIR (forward looking infrared), for example, the drone could fly high above tube and monitor heat profile of large sections of tube. For example, expelled or leaked gas from within the tube may have different heat signature than ambient air around tube. By implementing aspects of the present disclosure, leaks, which otherwise may be invisible to the naked eye, would be detectable as large plumes on the FLIR image. In embodiments, by flying at high altitudes, the imaging camera could provide larger scope of leaks in the tube system than conventional pressure transducers and measurement devices.
Laying Cables in the Transportation System
Proper cable/electrical line management and distribution will be an important to the success and longevity of the tube transportation system. Laying and replacing cables over such large distances may require a constant workforce and large amounts of monetary resources. Aspects of the present disclosure are directed to a system and apparatus for cable/electrical line management and distribution in the tube (or other low-pressure environment) transportation system. In an exemplary and non-limiting embodiments, a robot configured to traverse the tube, is also configured to transport and properly lay down lines of cables. In embodiments, a robot (or robotic vehicle) may be outfitted with large spool of wire/cable and with the capability of splicing and joining existing wiring. By implementing aspects of the disclosure, the cable-laying robot/vehicle could efficiently perform the task of laying wire autonomously, decreasing the man-power used to perform cable management and distribution. The tube profile of embodiments of the transportation system, e.g., obtuse tube profile, and the tubes possible remote location add difficulty to the task of laying and managing cable/wire. By implementing aspects of the disclosure, the difficult task would be alleviated by an autonomous cable-laying robot/vehicle. In embodiments, the robot (or robotic vehicle) may be configured to utilize the capsule transportation system to propel the robot (or robotic vehicle).
System Environment
Aspects of embodiments of the present disclosure (e.g., control systems for the tube environment, capsule control systems, tube orientation, tube switching systems) can be implemented by such special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions and/or software, as described above. The control systems may be implemented and executed from either a server, in a client server relationship, or they may run on a user workstation with operative information conveyed to the user workstation. In an embodiment, the software elements include firmware, resident software, microcode, etc.
As will be appreciated by one skilled in the art, aspects of the present disclosure may be embodied as a system, a method or a computer program product.

Although the present specification describes components and functions that may be implemented in particular embodiments with reference to particular standards and protocols, the disclosure is not limited to such standards and protocols. Such standards are periodically superseded by faster or more efficient equivalents having essentially the same functions. Accordingly, replacement standards and protocols having the same or similar functions are considered equivalents thereof.
The illustrations of the embodiments described herein are intended to provide a general understanding of the various embodiments. The illustrations are not intended to serve as a complete description of all of the elements and features of apparatus and systems that utilize the structures or methods described herein. Many other embodiments may be apparent to those of skill in the art upon reviewing the disclosure. Other embodiments may be utilized and derived from the disclosure, such that structural and logical substitutions and changes may be made without departing from the scope of the disclosure. Additionally, the illustrations are merely representational and may not be drawn to scale. Certain proportions within the illustrations may be exaggerated, while other proportions may be minimized. Accordingly, the disclosure and the figures are to be regarded as illustrative rather than restrictive.
Accordingly, the present disclosure provides various systems, structures, methods, and apparatuses. Although the disclosure has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Changes may be made within the purview of the appended claims, as presently stated and as amended, without departing from the scope and spirit of the disclosure in its aspects. Although the disclosure has been described with reference to particular materials and embodiments, embodiments of the invention are not intended to be limited to the particulars disclosed; rather the invention extends to all functionally equivalent structures, methods, and uses such as are within the scope of the appended claims.
While the computer-readable medium may be described as a single medium, the term “computer-readable medium” includes a single medium or multiple media, such as a centralized or distributed database, and/or associated caches and servers that store one or more sets of instructions. The term “computer-readable medium” shall also include any medium that is capable of storing, encoding or carrying a set of instructions for execution by a processor or that cause a computer system to perform any one or more of the embodiments disclosed herein.
The computer-readable medium may comprise a non-transitory computer-readable medium or media and/or comprise a transitory computer-readable medium or media. In a particular non-limiting, exemplary embodiment, the computer-readable medium can include a solid-state memory such as a memory card or other package that houses one or more non-volatile read-only memories. Further, the computer-readable medium can be a random access memory or other volatile re-writable memory. Additionally, the computer-readable medium can include a magneto-optical or optical medium, such as a disk, tapes or other storage device to capture carrier wave signals such as a signal communicated over a transmission medium. Accordingly, the disclosure is considered to include any computer-readable medium or other equivalents and successor media, in which data or instructions may be stored.
Although the present application describes specific embodiments which may be implemented as code segments in computer-readable media, it is to be understood that dedicated hardware implementations, such as application specific integrated circuits, programmable logic arrays and other hardware devices, can be constructed to implement one or more of the embodiments described herein. Applications that may include the various embodiments set forth herein may broadly include a variety of electronic and computer systems. Accordingly, the present application may encompass software, firmware, and hardware implementations, or combinations thereof.
One or more embodiments of the disclosure may be referred to herein, individually and/or collectively, by the term “invention” merely for convenience and without intending to voluntarily limit the scope of this application to any particular invention or inventive concept. Moreover, although specific embodiments have been illustrated and described herein, it should be appreciated that any subsequent arrangement designed to achieve the same or similar purpose may be substituted for the specific embodiments shown. This disclosure is intended to cover any and all subsequent adaptations or variations of various embodiments. Combinations of the above embodiments, and other embodiments not specifically described herein, will be apparent to those of skill in the art upon reviewing the description.
The Abstract of the Disclosure is provided to comply with 37 C.F.R. §1.72(b) and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, various features may be grouped together or described in a single embodiment for the purpose of streamlining the disclosure. This disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter may be directed to less than all of the features of any of the disclosed embodiments. Thus, the following claims are incorporated into the Detailed Description, with each claim standing on its own as defining separately claimed subject matter.
The above disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments which fall within the true spirit and scope of the present disclosure. Thus, to the maximum extent allowed by law, the scope of the present disclosure is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
Accordingly, the novel architecture is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
While the disclosure has been described with reference to specific embodiments, those skilled in the art will understand that various changes may be made and equivalents may be substituted for elements thereof without departing from the true spirit and scope of the disclosure. While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the embodiments of the disclosure. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. In addition, modifications may be made without departing from the essential teachings of the disclosure. Furthermore, the features of various implementing embodiments may be combined to form further embodiments of the disclosure.
The present application claims the benefit of U.S. Provisional Application No. 62/113,511 filed on Feb. 8, 2015, the disclosure of which is expressly incorporated by reference herein in its entirety.
