Embodiments of the present disclosure relate to transportation systems and, more particularly, to a clean energy integrated transportation system used to transport goods between multiple locations.
As the world and our nation looks to confront climate change to avoid irreversible impacts of global warming and continued impacts of more severe weather changes, new disruptive innovation and technologies are needed to transition away from the largest contributor of greenhouse gas emissions, which is by far the Transportation Sector. Conventionally, transportation of goods over long and short distances require the use and coordination of multiple different vehicle types, the vast majority of which release large amounts of carbon into the environment. For example, mail delivery often relies on planes and/or large trucks to provide interstate transportation, followed by smaller mail delivery vehicles once in a destination city. Due to an increased eCommerce demand for faster delivery of purchased goods (e.g., two-day, one-day, or even same-day delivery) and food delivery services, particularly in urban and suburban regions with large population densities, an increasing number of vehicles are present on the roadways, railways, and airways.
The current transportation systems contribute to a wide range of complex problems related to global warming, environmental degradation, human health implications, and large continued emissions of greenhouse gases. Compounding these problems, natural disasters and other extreme weather events are becoming more commonplace due to climate change. These weather events impede the fast and reliable delivery of goods to people in affected areas, including those in need of emergency supplies like clean drinking water and medicine.
It is now recognized that a need exists for disruptive innovations that offer to build greater eco-friendly transportation resilience for fast, reliable, efficient and net carbon neutral methods for transporting items over distances both large and small.

For a more complete understanding of the present disclosure and its features and advantages, reference is now made to the following description, taken in conjunction with the accompanying drawings, in which:
Illustrative embodiments of the present disclosure are described in detail herein. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation specific decisions must be made to achieve developers' specific goals, such as compliance with system related and business related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of the present disclosure. Furthermore, in no way should the following examples be read to limit, or define, the scope of the disclosure.
The present disclosure provides a clean energy transportation system that offers transformational changes to the existing methods of motor vehicle transportation. Adopting the new technological advances described herein will enable significant operating changes to meet the new supply and demand requirements of the growing eCommerce economy, while being environmentally friendly and safe to better serve humanity. The clean energy transportation system described herein provides a low-cost, pollution-free, land resource and space saving transportation system suitable for all kinds of items including appropriately sized mail, packages, medicine, food, toxic chemicals, nuclear waste, and water, among others.
Disclosed embodiments are directed to systems and methods for transporting items between multiple locations through a network of transportation tubes. The items may be disposed in one or more transportation pods, which are propelled through the tubes via associated transportation actuators. The network of transportation tubes and their transportation actuators may deliver items in the transportation pods from a location at one node of the network of tubes to a location at any other node in the network of tubes. The network of transportation tubes may include tubes that are at least partially underground. In other embodiments, at least one or more of the tubes may be located above ground.
The disclosed systems and methods provide a re-thinking of the future of transportation in response to consumers and suppliers being continuously faced with higher costs, labor shortages, and regular bottlenecks in ports, roads, highways, and airports. The disclosed systems and methods may improve the efficiency of on-time delivery of goods to customers. In particular, the disclosed transportation systems and methods may operate with high speed, efficiency, and reliability compared to existing transportation techniques, since the speed through which items are transported in the tube does not depend on weather or traffic conditions. The disclosed transportation systems and methods may be used to deliver letter-based mail, packages, food (e.g., groceries or prepared foods), pharmaceuticals, transplant organs, emergency supplies, drinking water, household goods, other retail products, storm water, building materials, tubulars, hazardous chemicals, waste matter, and other goods to one or more locations connected by the network of tubes.
The disclosed transportation systems and methods are environmentally friendly and sustainable, since propelling the transportation pods through the network of transportation tubes may produce no or very low carbon emissions, much lower than is possible using existing transportation techniques. For example, the transportation systems and methods may be fueled partially or entirely by wind energy, solar energy, natural gas, hydrogen, and/or hydro-power (e.g., water-powered). The disclosed transportation systems and methods may reduce the need for additional trucks, delivery vehicles, and private vehicles on the road, thereby improving road conditions, reducing traffic, and reducing emissions. As such, the disclosed transportation systems and methods are a major re-orientation and re-alignment of existing systems that is disruptive to create a better mode of delivery. The disclosed transportation systems and methods aim to be operationally carbon neutral. In addition, the disclosed transportation systems and methods may even have a net “carbon negative” impact on the transportation industry by offsetting or displacing millions of motor vehicles that would otherwise be releasing emissions and polluting the air. The disclosed transportation systems and methods may be particularly beneficial in urban and suburban regions, where the population density and demand for delivery services is higher.
The use of a partially subsurface and partially above surface transportation system that is fueled by solar, wind, and/or natural gas creates a practical process to bring about broad-based changes to: catalyze rapid delivery shifts, offer engineering solutions, and develop new infrastructures to address complex problems in polluted and congested urban cities and states. The disclosed technology may accelerate the transition to a cleaner economy while building resilience to provide necessities to people impacted by severe weather-related calamities.
Turning now to the drawings,
Any underground portions 114 of the tube 102 may be located at a desired depth 116 underground. The depth 116 may be selected depending on various factors, such as the geography, topography, and/or geology of the earth spanning the locations 104 and 106 connected by the tube 102. In some embodiments, the tube 102 may include underground portions that are located below the waterline or water table in the region through which the tube 102 extends. This may prevent certain environmental risks in the event of a leak in the tube 102 and/or pod 108. In other embodiments, the tube 102 may include an underground portion 114 that extends through one or more bodies of water.
In certain embodiments, sections of the tube 102 which are located underground may be surrounded by a protective structure 600, as shown in
Turning back to
The tube 102 may have any desired length for transporting pods 108 holding items between different locations 104/106. In an embodiment, the tube 102 may have a length on the order of, for example, tens of meters, hundreds of meters, miles, or up to hundreds of miles, depending on which locations 104/106 the tube 102 is connecting. For example, a shorter length tube 102 may be used to connect two buildings in a city's medical center or central business district. On the other hand, a longer length tube 102 may be used to connect a location in one city to a location in another city located hundreds of miles away.
The tube 102 may be built to accommodate any desired length of pods 108. In certain embodiments, one or more pods 108 transported through the tube 102 may have a length of between, for example, 8 inches and 72 inches, more particularly between 24 inches and 36 inches. This may be the case, for example, when the tube 102 is being used to deliver standard letter mail, mailed packages, food, or other delivered goods. In certain embodiments, one or more pods 108 transported through the tube 102 may have larger lengths, such as a length between, for example, greater than 6 feet, more particularly greater than 18 feet, and more particularly approximately 30 feet or more. This may be the case, for example, when the tube 102 is being used to deliver certain building materials such as, for example, lengths of pipe (e.g., typically about 30 feet) being transported as supplies for oil and gas operations (e.g., transportation to a well site or for construction of a pipeline). In such instances, the tube 102 itself may be constructed such that the tube between the two locations 104/106 does not have sharp direction changes but rather is substantially straight along its entire length. Shorter pods 108 may be transported along substantially straight or curved sections of tubes 102 within the network of tubes.
As illustrated, the tube 102 may include multiple portions having different relative orientations of the tube with respect to a horizontal plane. For example, the tube 102 may include one or more substantially vertical sections 134 extending downward from an access point (e.g., 110, 112). In an example, the tube 102 may include one or more substantially horizontal sections 136 (e.g., extending longitudinally underground) between the first location 104 and the second location 106. Although the illustrated tube 102 features substantially vertical and horizontal sections 134 and 136, other embodiments may include substantially straight or curved sections of the tube 102 that extend at any desired angle relative to the surface 126 of the earth. For example, in other embodiments, the tube 102 may include one or more angled sections that do not reach a substantially vertical orientation but still lower the tube below ground.
The tube 102 may include one or more bends 132 transitioning between the vertical, horizontal, and/or angled sections of the tube 102. In addition, the tube 102 may include one or more bends 132 transitioning the tube 102 to extend in different directions within the same substantially horizontal plane. Further, the tube 102 may include one or more bends 132 that transition the orientation of the tube 102 between any first and second direction in three dimensions. The diameter 118 of the tube 102 and the radius of curvature of any bends 132 in the tube 102 may be selected to be large enough that the pod 108 is able to effectively travel along the bends 132 without becoming stuck.
The tube 102 provides a line through which pods 108 may be directed between different locations 104 and 106. The tube 102 also provides protection from the surrounding environment so that the pod 108 is able to proceed quickly from one location to another along the tube 102.
The pod 108 is configured to receive and enclose items therein. The pod 108 functions as a container to hold one or more items being transported between the first and second locations 104 and 106. In an embodiment, the pod 108 is substantially cylindrical in shape. A cylindrical shape may help to maximize the holding capacity of the pod 108 while enabling the pod 108 to move easily through the tube 102. In other embodiments, different shaped pods 108 may be used. For example, in certain embodiments the pods 108 may be spherical, ellipsoid, rectangular prismatic, conical, or irregular in shape. The pod 108 may include one or more openings through which items may be loaded into one or more inner compartments of the pod 108. The openings may be selectively closed once the items are loaded to keep the items contained within the pod 108. It may be desirable to substantially fill the internal volume of the pod with item(s) (e.g., with one large item or several smaller items). Packing multiple items into the pod 108 tightly may help the items to not shift during transfer of the pod 108 between the first and second locations 104 and 106. A similar effect may also be accomplished by placing packing materials (e.g., cardboard, packing peanuts, paper, bubble wrap, etc.) in the internal volume of the pod 108 around the item(s) enclosed in the pod.
In some embodiments, multiple pods 108 may be connected together end to end and moved through the tube 102 in tandem. In certain instances, the first (lead) pod in the group of pods connected end to end may include a motor assembly for self-propelling the group of pods through the tube 102 in the event that the primary transportation actuator within the tube 102 (e.g., the motor-driven cable 124, pumps, etc.) malfunctions.
The tube 102 and pod(s) 108 may be used to transport various types of materials including, for example, letter mail, packaged mail, groceries, prepared delivery food, drinking water (e.g., in large or small bottles), household goods, other retail products, medicine (including pharmaceuticals and vaccines), human organs being transported to hospitals, for example, during inclement weather events, agricultural materials, construction materials, supplies for oil and gas operations (e.g., pipes, sand, proppant, electrical lines, hoses, other equipment, etc.), oil and gas products being transported (e.g., liquefied natural gas), chemicals, waste materials, radioactive materials, recyclables, volumes of storm water or clean water, and any other materials that fit within a particular sized pod 108. Certain tubes 102 in a tube transportation network may be designated for carrying certain types of items to accommodate, for example, a particular size or hazard level of the materials being transported.
The pod(s) 108 may be reusable, such that the same pod 108 may be used to transport one item or a first group of items from the first location 104 to the second location 106 and then later used to transport another item or a second group of items from the second location 106 to another location (e.g., back to the first location 104). In this way, the reusable pod(s) 108 may replace cardboard that is often used to package materials for delivery in existing systems, thereby reducing the amount of waste in landfills.
In an embodiment, the pod 108 may be equipped with a centralizer 120, as shown. The centralizer 120 may be a spring-loaded centralizer. The centralizer 120 may keep the pod 108 centered within the tube 102 and allow the pod 108 to effectively move through bends 132 in the tube 102 without becoming stuck. The centralizer 120 may include rollers or a surface with a smooth texture to reduce or minimize an amount of friction between the pod 108 and the tube's internal wall.
In an embodiment, the pod 108 may be equipped with mechanical features and software that enable the pod 108 to function as a drone when the pod 108 is outside of the tube 102. In some embodiments, for example, the pod 108 may be operated as a drone once it is removed from the tube 102 at an access point (e.g., 110 or 112) to fly through the air via rotating blades, roll along the ground on wheels, roll through desert or other difficult terrain via one or more wheels, move underwater with propellers, or a combination thereof.
The system 100 also includes a transportation actuator 122 configured to propel the pod 108 through the tube 102. In certain embodiments, e.g., as depicted in
When two or more cables 124 are used to pull the same pod 108 through one tube 102, it is desirable to precisely control the speed of the cables 124 to ensure that all cables 124 are moving at the same speed and the pod 108 does not become stuck in the tube 102. To that end, it may be desired to mechanically link the motors used to pull the cables 124 through the tube 102, to use a highly accurate controller to control the speeds of the motors, or to use a single motor to actuate both cables 124 simultaneously. Other constructions of a cable-based system for pulling pods at high speeds through tube 102 may be used in the disclosed transportation systems.
In certain embodiments, the one or more cables 124 extending through the tube 102 may be configured to transmit electricity therethrough. For example, the cables 124 may be constructed with one or more electric lines embedded therein. The one or more interior electric lines may be conductive lines surrounded by one or more layers of insulating material and then surrounded by one or more additional layers including an outer protective layer of the cable 124. The outer protective layer of the cable 124 may be a metal, thermoplastic, other polymer, or composite material layer designed to interface with the attachment mechanism 700 used to carry the pod 108 through the tube 102. Electrical transmission through the cable 124 may be used to supply power between the two locations 104/106. In this way, the cable 124 may function as an electrical transmission line. In certain embodiments, the electrical transmission through the cable 124 may be used to provide electrical power for operating a motor (e.g., 138 of
In some embodiments, electrical transmissions lines may be secured inside the tube(s) 102 spanning various areas of critical infrastructure across a city and/or state, regardless of whether the electrical lines form part of a cable (e.g., 124) used to physically propel the pods 108. Securing transmission lines within the disclosed tube(s) 102 may protect the power grid from severe weather and climate events including, for example, strong winds or fires. In some embodiments, transportation tube 102 may include a mat constructed from rubber (or another insulating material) located between the cable 124 with its electric line and an interior edge (e.g., top) of the tube 102.
Some connecting lines 804A may function as “exit ramps” with respect to the illustrated main line 802 and may include a brake or other mechanism used to reduce the speed of the cable at it moves along the length of the connecting line 804A away from the main line 802. Pods (e.g., 108 of
In other embodiments, different types of transportation actuators (e.g., other than cable(s)) may be used. For example, the pods may be self-propelled through the tube. As such, the transportation actuator may include one or more motors that are either integral to or removably attached to the individual pods being moved through the tube 102. In some embodiments, the motor used to self-propel a pod 108 through the tube 102 may be used as a back-up transportation actuator in the event that another transportation actuator (e.g., motor-driven cable, pumps, etc.) in the tube 102 malfunctions.
The motors 900 in the pods 108 and/or carriages 904 may be individual electric motors 900 operated by a battery power supply. The battery power supplies may be re-charged at a receiving station at the end of the tube 102. In other embodiments, the motors 900 in the pods 108 and/or carriages 904 may be electric motors 900 that are operated via electric power supplied by an electric cable extending through the tube. A cable extending through the tube 102 to provide electrical energy for operating the motors of the pod 108 and/or carriage 904 may be embedded in a floor or pad of the tube 102 in certain embodiments. However, other locations of such an electric cable may be possible in other embodiments.
For pods 108 that are self-propelled through the tube 102 (either by themselves or via attachment to a movable carriage), the tube 102 may include a track, pad, and/or rail along which the pods 108 ride through the tube 102.
As illustrated in
In other embodiments, the flat pad 1000 may not be present at all, but the pod 108 and/or carriage may instead comprise wheels 902 that interface directly with the radially inner edge of the tube 102 to essentially “roll” the pod 108 along the length of the pipe 102. In such embodiments, the wheels 902 may extend out from the pod 108 at different angles around the outer circumference of the pod 108.

In other embodiments of the system of
In another example, the transportation actuator 122 may include a pneumatic actuator designed to propel the pod 108 through the tube 102 via pressurized air forced against a longitudinal end of the pod 108. Pneumatic actuation of the pod 108 through the tube 102 may be more practical for transporting the pod 108 over shorter distances rather than longer distances between the locations 104 and 106.
In another example, the transportation actuator 122 may include one or more pumps coupled to the tube 102 and configured to pump a fluid medium through the tube 102, wherein the pressurized fluid propels the pod 108 through the tube 102.
The transportation fluid being pumped through the tube 102 may include water in some embodiments. The water may be filtered or otherwise controlled to have a certain cleanliness, conductivity, and/or concentration of dissolved contents in the water. In other embodiments, the water may contain contaminants and thus only be slightly filtered, if at all. In some instances, the water may be storm water needing to be removed from the area of the first location after a large rainfall or natural disaster. In some embodiments, the first location may be a city or region (e.g., some parts of Texas, Louisiana, Florida, etc.) that is prone to large amounts of rainfall, flooding, hurricanes, sea level rise, and/or other natural disasters, while the second location may be in a region prone to drought or having little available water (e.g., some parts of California, Nevada, etc.). As such, the fluid being pumped through the tube 102 may function as both the transportation actuator 122 used to propel pods 108 through the tube 102, as well as a product itself that is being delivered through the tube 102 from the first location to the second location. Upon reaching the second location, at least a portion of the transportation water may be sold at the second location, provided for commercial use at the second location, or reused for transporting items to another location in the transportation network.
In other embodiments, the transportation fluid being pumped through the tube 102 may include a high viscosity fluid, such as a gel. The gel transportation fluid may be specially formulated to prevent erosion of the inside of the tube 102 and/or the pods 108 being propelled through the tube 102. The use of a gel as the transportation fluid may also prevent issues from arising due to differing levels of conductivity of the transportation fluid, thereby providing greater consistency in the transportation process than may be possible using water naturally occurring at the first location.
In some instances, the tube 102 may be equipped with one or more additional actuators as described above in addition to the pumps 1200. Such additional actuators may include, for example, at least one cable (e.g., 124), at least one track (e.g., 1100), at least one pad (e.g., 1000), at least one pneumatic actuator, electromagnets, or any desired combination thereof. Alternatively, or additionally, the pods 108 may be equipped with on-board transportation actuators (e.g., motors) to enable the pods 108 to move through the tube 102. These additional actuators (e.g., in the tube 102 and/or the pods 108 themselves) may function as secondary actuators (e.g., backup actuators) used to propel the pods 108 through the tube 102 in the event that one or more of the pumps 1200 malfunctions. In other embodiments, the additional actuators may function as the primary mode for actuating the pods 108 through the tube 102, and the pumps 1200 may be used to propel the pods 108 through the tubes 102 only whenever water or another type of fluid medium is available for pumping.
Any of the above described types of transportation actuators 122 (e.g., cable(s), track(s), pad(s), pumps pumping a fluid medium, pneumatic actuators, electromagnets, on-board motors, etc.) may be used either alone or in combination with each other to propel the pods 108 through the tube 102. In an embodiment, a first type of transportation actuator 122 may provide a primary mode of actuation while a second type of transportation actuator 122 serves as a backup. Other types of transportation actuators 122 may be used to move the pod 108 through the tube 102 than those described herein. For example, the transportation actuators 122 may include any actuator or equipment capable of propelling a body through a tube.
Turning back to
The access points 110/112 may provide space necessary for a user, a separate conveyor, or a robotic component to position the pod 108 into engagement with the cable 124 (or other transportation actuators), thereby allowing the cable to move the pod 108 through the tube 102. In embodiments where the pod 108 is pneumatically propelled through the tube 102, one or both access points 110/112 may include a pneumatic actuator (e.g., one or more valves) coupled to a source of pressurized air. The opening 130 may be positioned on a first side of the valve while the source of pressurized air is on the opposite side of the valve.
In certain embodiments, one or both of the access points 110/112 may include a launcher and/or receiver. The launcher may function similarly to and include similar components as a pig-launcher used to position a monitoring pig into a pipeline. For example, the launcher may include a launch barrel with the opening 130 being a cap or door to the launch barrel. The receiver may function similarly to and include similar components as a pig-receiver used to retrieve a monitoring pig from a pipeline. For example, the receiver may include a receiver barrel with the opening 130 being a cap or door to the receiver barrel. For the launcher and/or receiver at the access points 110/112, the cap or door of the respective barrels may be disposed at a longitudinal end of the barrels extending from the tube 102.
It may be desirable to have three tubes 102 for each line connecting two locations. A first tube 102 may be configured to transport items in pods 108 in a first direction (e.g., toward the launching/receiving center 1300). This tube 102 is therefore a “receiving” or “incoming” tube. A second tube 102 may be configured to transport items in pods 108 in a second (opposite) direction (e.g., away from the launching/receiving center 1300). This tube 102 is therefore a “launching” or “outgoing” tube. A third tube 102 may be configured to transport items in pods 108 in either the first (incoming) direction or the second (outgoing) direction, whichever is needed depending upon the demands in of the two other directions. Furthermore, the third tube 102 may also be reserved as a backup tube in the event that either of the first or second tubes experience an issue.
It should be noted that while three tubes 102 are shown terminating the same “line” at the launching/receiving center 1300, any desired number of tubes 102 may terminate a line at the launching/receiving center 1300 in other embodiments. For example, a single line of tubes connecting two nodes in a network of the disclosed transportation system may include 1, 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or more tubes 102 configured to carry pods 108 in one or both directions along the line. Although the three tubes 102 illustrated in
In
In embodiments where a fluid such as water or gel is used to propel the pods 108 through one or more tubes 102, each associated tube 102 may include a drying station that is located proximate the gate 1301 at the end of the tube 102. The drying station may refer to, among other things, a portion of the tube 102 in which the actuating fluid is diverted or drained from the tube 102 to another location while the gate 1301 is closed. The drying station may also refer to a portion of the tube 102 or a location just outside the gate 1301 in the launching/receiving center 1300 having one or more fans used to dry the outside of the pods 108 that were propelled by the fluid.
As illustrated, a line 1302 may extend from each tube 102 into the launching/receiving center 1300, allowing the pods 108 to enter an open space of the launching/receiving center 1300 from the tube 102, or vice versa. The lines 1302 extending from the tubes 102 may be of similar or different construction from a track, pad, rail, cable, and/or other transportation actuator present within the corresponding tube 102. The lines 1302 extending from the tubes 102 are exposed within the launching/receiving center 1300 so that the pods 108 and/or items enclosed therein can be easily removed from or loaded onto the lines 1302 and associated tubes 102. The lines 1302 may be elevated (e.g., between approximately 6 and 50 feet, more particularly between 12 and 30 feet) above a factory or distribution center floor, as shown in the illustrated embodiment. In other embodiments, the lines 1302 may be within approximately 3 to 6 feet, more particularly within 4 to 5 feet, of the floor so that users can manually load and/or retrieve items from the pods 108.
As illustrated, one or more readers 1304 (e.g., barcode scanners, RFID readers, or others) may be present at each launching/receiving center 1300. Each pod 108 may include a barcode, an RFID tag, or some other identification component 1306 disposed thereon that may be read by the one or more readers 1304 upon entering any launching/receiving center 1300 (e.g., each time the pod 108 is moved through an access point). In some embodiments, one or more items held inside the pod 108 may include a barcode, an RFID tag, or some other identification component thereon that may be read by the one or more readers 1304 upon being removed from the pod 108, e.g., at the launching/receiving center 1300. In some embodiments, the readers 1304 may be entirely automated. For example, as illustrated in
In some embodiments, one or more automation components may be present at the launching/receiving center 1300 to provide automated loading of the pod 108 onto the line 1302 and/or into the tube 102, automated retrieval of the pod 108 from the tube 102 and/or the line 1302, automated loading of items 1308 into a pod 108, automated unloading of items 1308 from a pod 108, or a combination thereof. An example of automation components may include, for example, a robotic arm 1310 or other robotic component configured to extract the pod 108 from the line 1302 extending from the tube 102, configured to position the pod 108 onto the line 1302 extending from the tube 102, configured to unload items 1308 from pods 108 on the line 1302, configured to load items 1308 into pods 108 on the line 1302, or configured to selectively perform multiple of these operations. Another example of automation components may include a conveyor 1312 configured to deliver pods 108 from the line 1302 extending from one tube 102 to one or more other locations, configured to unload items 1308 from pods 108 on the line 1302, configured to deliver pods 108 from one or more other locations to the line 1302, configured to load items 1308 into pods 108 on the line 1302, or configured to selectively perform multiple of these operations. Other types of automation equipment may be used at the launching/receiving center 1300 in other embodiments. A combination of different types of automation equipment (e.g., robotic arm(s), conveyor(s), etc.) may be used at the same launching/receiving center 1300. The conveyors 1312 and/or robotic arms 1310 may be used at a launching/receiving center 1300 to transfer pods 108, or items 1308, between loading/unloading points associated with different lines of tubes. Thus, a pod 108 received at the launching/receiving center 1300 from one of the illustrated tubes 102 may be transferred using the automated components to another tube 102 for launching toward a new location from the launching/receiving center 1300. Multiple components of automation equipment and/or delivery paths may be used within the launching/receiving center 1300 to move pods 108 (or items 1308) between one set of tubes 102 and another.
In certain embodiments, the launching/receiving center 1300 may be an end point to which items in a pod 108 were being transported. As such, the launching/receiving center 1300 may be equipped with one or more lockers for holding items 1308 waiting to be picked up, a panel or shelving system for holding unused pods 108 that have been emptied, or a combination thereof. The automation equipment (e.g., robotic arms 1310, conveyors 1312, etc.) may automatically direct and/or deliver the items 1308 from a pod 108 to a specific locker and/or the emptied pod 108 to a location. The pod 108 and/or contents of a pod 108 may be assigned to a particular locker based on identification data read via the reader 1304 at the launching/receiving center 1300. In some embodiments, the movement of items 1308 and/or pods 108 at the launching/receiving center 1300 may be managed manually by people loading/unloading pods 108 from the tube 102 and moving contents 1308 of the pod 108 to desired locations.

The system 100 may be operated to transport items with relatively low or no carbon emissions. The term “carbon emissions” may refer to any one or more of several greenhouse gases such as, for example, carbon dioxide, methane, nitrous oxide, ozone, hydrofluorocarbons, and water vapor, among others, that add to global warming. For example, in an embodiment, the transportation actuator 122 may receive energy from one or more solar-based power generation systems, one or more wind-based power generation systems, one or more hydrogen-based power generation system, hydro-powered generation systems, other “green” technology being developed, or a combination thereof. In another embodiment, the system 100 may utilize natural gas to fuel operation of the transportation actuator 122. That is, the system 100 may be operated by burning natural gas as fuel to operate the transportation actuator 122, which propels the pod 108 through the tube 102. Such operations may lead to net zero carbon emissions for transporting goods over long and short distances. When comparing the amount of emissions (if any) output from the disclosed transportation process to the amount of emissions that would otherwise be output from using existing transportation vehicles (e.g., cars, trucks, airplanes, boats, etc.) to transport the same amount of goods, the difference may suggest a net negative carbon emissions effect of switching to the disclosed transportation method.
Forming an integrated transportation system 100 with one or more underground portions 114 may involve drilling a tunnel through the earth and laying the tube 102 in the tunnel. Formation of the tunnel may involve the use of directional drilling equipment that can form the bends 132 and transition the resulting tunnel between different orientations with respect to the earth's surface 126. Formation of the tunnel may involve the use of micro-tunneling equipment, particularly for forming elongated substantially horizontal sections 136. In some embodiments, at least a portion of the tube 102 may be laid as the tunnel is being drilled (e.g., using casing-while-drilling equipment). In other embodiments, the tunnel may be partially or entirely drilled and then the tube 102 may be laid in the pre-drilled tunnel.
The tube 102 may be constructed from steel, a composite material (e.g., including carbon fibers), flexible polyvinyl chloride (PVC), flexible fiberglass, or any other desired material having the strength to be pushed through a tunnel during installation of the tube 102. Materials having a moderate degree of flexibility may be desired, particularly for construction of tubes 102 in environments susceptible to earthquakes. In embodiments where a track, pad, and/or rail are located in the tube 102, the track, pad, and/or rail may be constructed from rubber, thermoplastic, or another material with some amount of flexibility to enable easy movement of the pods 108 through the tube 102. In some embodiments, the tube 102 may include a number of smaller tube sections that are threaded end to end or otherwise connected in series to form the tube 102. In other embodiments, the tube 102 may include a coiled tubing or similar type of continuous tube that is unspooled into the tunnel to form the tube 102. In embodiments where the tube 102 is a continuous spoolable pipe, the tube 102 may be prefabricated with one or more cables 124, a track, a pad, and/or rail(s) disposed therein so that these components are spooled out with the tube 102 while the tube 102 is originally laid.
The pod 108 may be sized to receive and hold average sized mail and small packages. The pod 108 may be substantially hollow. The pod 108 may include one large open compartment therein, or multiple separate compartments for receiving different items.
The pod 108 may be customized for use by a particular company or individual to which the items therein are being delivered. For example, in an embodiment, the pod 108 may include one or more security features 205 that enables only an intended recipient to access the interior compartment(s) of the pod 108 where their items are stored. Such security features 205 may include, for example, a keypad whereby an individual code may be input by the recipient to access the contents of the pod 108. The code may be a particular code associated with the recipient or password set by the recipient that is the same each time a pod 108 is accessed by the recipient. For added security, the code may be a single-use code that is generated by a control system and communicated to the recipient via an email, SMS, MMS, or some other method for one-time use opening the pod 108. In an embodiment, the security features 205 may include a fingerprint scanner, retina scanner, camera communicatively coupled to facial recognition software, or other biometric scanner used to confirm the identity of the recipient prior to allowing access to the contents of the pod 108. In an embodiment, the security features 205 may include a physical key that must be input to the corresponding pod 108 assigned to the recipient. In an embodiment, the security features 205 may include a video camera configured to automatically record a video of the outside and/or inside of the pod 108 upon the pod 108 being unlocked or opened. In an embodiment, the security features 205 of any given pod 108 may include multiple different types of security features described above to provide multi-level identification of the recipient (e.g., using biometric scanning and a physical key to open the pod 108).
In some embodiments, the pod 108 may be temperature controlled. For example, the temperature in the pod 108 may be passively controlled via one or more of an insulating material built into or placed in the pod 108, ice packs or heat packs placed in the pod 108, or other methods to keep the contents at a desired temperature (e.g., keeping hot food hot, cold items cold, frozen items frozen, medicines cold, etc.). Insulating materials that may be built into or placed in the pod 108 may include, for example, polyurethane foam, polystyrene foam, polypropylene, polyethylene foam, phenolic foam, expanded synthetic rubber, expanded nitrile rubber, cork, Styrofoam, resin sheets, steel or aluminum plates to sandwich between other materials for framing maximum refrigeration of the pod 108, gel layers, or a combination thereof. In an embodiment, the insulating materials in the pod 108 may include a double layer of insulation with a gel layer in between.
Actively temperature-controlled pods 108 may be particularly useful for transporting medications, vaccines, transplant organs, or other medical or pharmaceutical items. In an embodiment, the pod 108 may be equipped with a battery powered cooling unit therein to maintain a desired cold temperature environment in the pod 108. In another embodiment, the pod 108 may be equipped with a battery powered heating unit therein to maintain a hot temperature environment in the pod 108. Actively heated pods 108 may be particularly useful for transporting certain materials such as construction materials, heavy metals, or materials that need to be kept in a certain state. Pods 108 equipped with active heating control may be constructed from different materials (e.g., platinum) than non-heated pods.
As illustrated, the transportation system 1400 may further include an active heat exchange system 1406 in or surrounding the tube 102 to control the temperature of the tube 102 to be within a desired range. The active heat exchange system 1406 may include a refrigeration coil, a thermoelectric cooling coil, a thermoelectric heating coil, or any other desired active temperature management system. Some embodiments of the tube 102 may include multiple types of active heat exchange systems 1406 that can be selectively operated as desired based on an ambient temperature surrounding the tube 102 and/or the cargo being transported in pods 108 through the tube 102. In some embodiments, the tube 102 may include multiple thermoelectric coils located at different positions along the length of the tube 102 and operated either independently or all together. The tube 102 may be equipped with one or more temperature sensors 1408 disposed therein and a control system configured to operate the heat exchange system 1406 to raise or lower the temperature in the tube 102 with respect to a predetermined temperature threshold. The tube 102 may include one or more sensors 1410 disposed therein and configured to detect an approximate temperature of the pods 108 moving through the tube 102. The tube 102 may include multiple sensors 1410 disposed therein and configured to detect an approximate temperature of the pods 108 moving through the tube 102 at positions along the entire length of the tube 102.

The pod 108 may include a spring-loaded centralizer, as described above with reference to
In some embodiments, the pod 108 may include control components (described below) and actuators such as motors used to propel and steer the pod 108 once it is retrieved from the tube at its destination location. In such embodiments, the pod 108 may function as a self-directed drone, self-directed submarine, or self-driving vehicle once it arrives at a destination location. In some embodiments, the pod 108 may be programmed to automatically travel to a particular docking station, locker, or bay (e.g., at a launching/receiving center) upon arriving at a particular destination. In certain embodiments, the pod 108 may be programmed to operate as a flying drone only, a self-driven (rolling) drone only, or a submarine (swimming) drone only. In other embodiments, the pod 108 may be programmed and equipped to operate as multiple of these different types of drones, depending on the readings of one or more sensors on the drone, communications received at a destination location, and/or communications received via a satellite or other network connection.
As shown in
Although pods 108 are shown in the above illustrated embodiments as being substantially cylindrical, the pod 108 may take other shapes and forms in other embodiments. For example, as shown in
The system 100 of
Each location 304 represents a node in the mesh-type network 300 of tubes, and each location 304 may include at least one access point (e.g., 110/112 of
The locations 304 of nodes in the network 300 of tubes may include critical infrastructure areas (e.g., an airport 304A, a medical center 304B, a central business district 304C, and so forth) within a city 306. The locations 304 of nodes may include a distribution center 304D and/or any other locations (e.g., 304E) within the city 306. In addition, the locations 304 of nodes may extend to suburbs 304F-304I of the city 306. Furthermore, the network 300 may include long-distance lines 302 connecting different cities (e.g., city 306, a second city 308, and a third city 310). Certain lines 302 in the network 300 may cross state lines, for example, connecting multiple major cities in the U.S. (or comparably distant cities in other countries). Having cities connected via the network 300 of tubes in an integrated transportation system may enable supplies to be sent quickly to a city experiencing (or preparing for) a natural disaster from unaffected cities.
In certain embodiments, one or more lines 302 may be laid in the same areas as pre-existing infrastructure such as pipelines, train lines, highways, etc. so that the lines 302 can take advantage of existing right-of-way designations. When placed in the same areas as pre-existing highways, the lines 302 may be placed under the highway or alongside the highway. In an embodiment, the line 302 may include two tubes designed and operated to transport pods in opposite directions, the opposite directions of the tubes corresponding to the same directions as the flow of traffic on the portions of the highway under/along which the tubes are placed.
Each illustrated line 302 in the network 300 may include one or more tubes (e.g., 102 of
One or more maintenance stations 390 may be located along one or more lines 302 of the network 300. The maintenance stations 390 may provide additional points at which the inside of the tube may be accessed. The maintenance stations 390 may serve as locations for performing maintenance on a tube (e.g., pigging the tube), removing a broken down pod from a tube, clearing a blocked tube, addressing mechanical issues with the transportation actuator of a tube, releasing air pressure that has built up in a section of the tube, or a combination thereof.
In the network 300, certain lines 302 (or certain tubes on a given line 302) may be designated as “unclean” lines designed for carrying potentially hazardous materials, such as certain chemicals (e.g., ammonia, non-oxidizing biocides, etc.), waste from chemical plants, nuclear waste (liquid or solid) and/or by-products thereof, other radioactive materials, rare Earth metals, lithium ion batteries for disposal or recycling, or dirty water (e.g., storm water). In some embodiments, the lines 302 or individual tubes that are designated “unclean” may be constructed with additional shielding to prevent any potentially hazardous materials from leaking into or otherwise affecting the surrounding environment or other nearby transportation tubes. This shielding may include particular materials used to construct the unclean tube, or additional layers of material or tubes between the host tube and the outside environment. In embodiments where water containing contaminants (e.g., storm water) is used as the transportation actuator for moving pods through one of the unclean lines, the pods may similarly be built with additional shielding in the form of specialized coatings. In some embodiments, only pods carrying industrial materials or the like may be transported in the unclean lines with water containing contaminants running therethrough.
Existing techniques for transporting radioactive material (e.g., used in medicine, power generation, research/manufacturing, the military, nuclear waste, etc.) is highly regulated and typically carried out using tanker trucks, planes, trains, ships, etc. Special packaging may be involved depending on how radioactive the material being handled is. By providing unclean lines for transportation of radioactive materials, the disclosed systems and methods are able to bypass the existing transportation systems using trucks, cars, planes, and ships. The disclosed systems and methods therefore offer the option to transport radioactive and other hazardous material with little to no human involvement. The unclean lines (and pods to be used therein) may be equipped with safety features and appropriate shielding to comply with all required environmental regulations for properly containing the hazardous materials.
One or more unclean lines in the network 300 may have an end that does not connect to another node at the surface of the Earth but is instead built in at least a partially vertical direction down toward the Earth's core. These unclean lines may be used to bury nuclear waste or other hazardous material far from the Earth's surface to prevent pollution of the ground and nearby water sources.
In the network 300, certain lines 302 (or certain tubes on a given line 302) may be designated as “secured” lines designed for carrying items that are desired to be hidden and undetectable by surveillance systems such as RADAR, 3D seismic imaging, etc. In some embodiments, the lines 302 or individual tubes that are designated “secured” may be constructed with shielding to prevent any outside surveillance systems from detecting either the pods being moved through the tube, the contents of the pods, or the tube itself within the surrounding (e.g., underground) environment. This shielding may include particular materials used to construct the secured tube, or incorporating additional layers of material (e.g., certain metals or types of rocks) or tubes between the host tube and the outside environment. Secured lines may also transport pods having different constructions than those used in non-secured lines. In addition, the secured lines may terminate at a shielded or hidden room or facility at its end point locations 304. Additionally, or alternatively, the “secured” lines may include a plurality of sensors disposed along the length of the transportation tubes for scanning and tracking the transportation pods as they move through the transportation tube.
Different standards for the lines 302 and their corresponding transportation tubes (e.g., 102 of
Industries which may have their own standards for their lines of the disclosed transportation system may include, for example: mail and food delivery, medical, military or government, agriculture, construction, oil and gas, chemical, recyclables, hazardous materials disposal, and water transportation. The following are some examples of different standards that may be applied in certain industries. It should be noted that these are examples and not an exhaustive list, and other standards may be applied depending on the needs of the particular industries in which the system is being used. In the chemical, recyclables, hazardous materials disposal, and water transportation industries, the lines 302 may be configured as “unclean” lines as discussed above. In the military or government industry, the lines 302 may be “secured” lines as discussed above, and/or the transportation pods may include one or more security features as discussed above. In the medical industry, the lines 302 may be temperature controlled (e.g., via temperature control of the transportation pods and/or tubes) as discussed above. When used to transport oil and gas products such as, for example, liquefied natural gas (LNG), the pods communicated through the lines 302 may be constructed from a very strong material (e.g., incorporating carbon fiber, etc.) to sustain the high pressures of the LNG.
In an embodiment, the pod 108 may include a controller 514 having a processor 516 and a memory 518. The memory 518 stores instructions thereon that, when executed by the processor 516, cause the processor 516 to perform various tasks in accordance with the present disclosure. The pod 108 may include a communication interface 520 configured to communicate with one or more other components such as, for example, the access point 110 or the transportation actuator 122. The communication interface 520 may transmit tracking information (e.g., via an RFID tag) associated with the pod 108 for detection by the access point 110 and/or the transportation actuator 122. The communication interface 520 may receive information from the access point 110 about a locker, docking station, or other precise location outside of the tube to enter at the access point and input this information to the controller 514. The controller 514 may output control signals to one or more other components on the pod 108 including, but not limited to, an electric motor 522 and/or steering device 524 so that the pod 108 can drive, fly, or swim to a desired location once retrieved at the access point 110. The pod 108 may also include one or more sensors 526, such as a camera (e.g., infrared camera) and/or pressure sensors to assist in steering the pod 108.
In an embodiment, the transportation actuator 122 may include a controller 528 having a processor 530 and a memory 532. The memory 532 stores instructions thereon that, when executed by the processor 530, cause the processor 530 to perform various tasks in accordance with the present disclosure. The transportation actuator 122 may include a communication interface 534 configured to communicate with one or more other components such as, for example, the pod 108 or the access point 110. The communication interface 534 may receive information from the access point 110 about a particular tube or direction in which to propel the pod 108 and input this information to the controller 528. The controller 528 may output control signals to one or more other components (e.g., motor, electromagnetic components, valves, and/or speed control components) of the transportation actuator 122 to direct the pod 108 through a tube. The transportation actuator 122 may also include one or more sensors 536, for example, for detecting a location and/or speed of one or more pods 108 in the tube.
The disclosed systems and methods for transporting items via pods 108 moving through tubes 102 may provide many benefits to modern society and the environment, particularly in light of current challenges due to climate change. In particular, the disclosed systems are immune to severe weather events associated with climate change, including floods, rising sea level, fires, and natural disasters that can block roadways and which under the existing transportation paradigm can reduce access to emergency supplies. The disclosed transportation system may provide a reliable, efficient, and weather-immune method for responding to natural disasters by quickly sending supplies where they are most needed. In terms of mail delivery, the disclosed transportation system may run 24/7 at a low cost and address ongoing labor shortages. The disclosed transportation system may operate with a net zero carbon footprint, while replacing inefficient and pollution-heavy plane/truck transportation systems to potentially reduce the overall amount of carbon emissions. Thus, the systems and methods disclosed herein may deliver goods in a way that is immune to extreme weather events, while also reducing the emissions that would otherwise exacerbate climate challenges. Lastly, due to the large amount of tunneling needed to lay the tubes underground, the disclosed transportation system would create many new jobs during its implementation on a large, national scale.
Although the present disclosure and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the scope of the disclosure as defined by the following claims.
This application is a Continuation-In-Part Application claiming the benefit of U.S. patent application Ser. No. 17/540,054, entitled “Clean Energy Integrated Transportation System,” filed on Dec. 1, 2021.
