List Of Proposed Future Transport
Transport today is mostly powered by fossil fuel. The reason for this is the ease of use and the existence of mature technologies harnessing this fuel source. Fossil fuels represent a concentrated, relatively compact source of energy. The drawbacks are that they are heavily polluting and rely on limited natural resources. There are many proposals to harness renewable forms of energy, to use fossil fuel more efficiently, or to use human power, or some hybrid of these, to move people and things. The list below contains some forms of transport not in general use, but considered as possibilities in the future. Proposed future transport * Air-propelled train (abandoned in 19th century) ** Bounce tube pneumatic travel (Proposed by Robert A. Heinlein in 1956) **Vactrain also known as ET3 * BiModal Glideway (Dual Mode Transportation System) travel (Proposed by William D. Davis, Jr. in 1967) * TEV Project (proposed by Will Jones in Summer 2012) * Dual-mode vehicle * Hyperloop * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Air Vehicle
A personal air vehicle (PAV) is a proposed type of aircraft providing on-demand aviation services. The emergence of this alternative to traditional ground transport methods has been enabled by unmanned aerial vehicle technologies and electric propulsion. Barriers include aviation safety, airworthiness, operating costs, usability, airspace integration, aircraft noise and emissions, tackled first by small UAS certification then experience. Definition The personal air vehicle (PAV) is intended to provide flight convenience similar to the private car in terms of accessibility and ease of operation, while also offering the speed and routing efficiencies made possible by direct point-to-point flight. The PAV differs from conventional general aviation types and flying cars in being usable by people with no pilot qualifications. History NASA established the Personal Air Vehicle Sector Project in 2002, as part of their Vehicle Systems Program (VSP). This project was part of the NASA ...

Space Elevator
A space elevator, also referred to as a space bridge, star ladder, and orbital lift, is a proposed type of planet-to-space transportation system, often depicted in science fiction. The main component would be a cable (also called a tether) anchored to the surface and extending into space. The design would permit vehicles to travel up the cable from a planetary surface, such as the Earth's, directly into orbit, without the use of large rockets. An Earth-based space elevator could not feasibly be simply a tall tower supported from below, due to the immense weight - instead it would consist of a cable with one end attached to the surface near the equator and the other end attached to a counterweight in space beyond geostationary orbit (35,786 km altitude). The competing forces of gravity, which is stronger at the lower end, and the upward centrifugal force, which is stronger at the upper end, would result in the cable being held up, under tension, and stationary over a singl ...

Jack Vance
John Holbrook Vance (August 28, 1916 – May 26, 2013) was an American mystery, fantasy, and science fiction writer. Though most of his work has been published under the name Jack Vance, he also wrote several mystery novels under pen names. Vance won the World Fantasy Award for Life Achievement in 1984, and he was a Guest of Honor at the 1992 World Science Fiction Convention in Orlando, Florida. The Science Fiction and Fantasy Writers of America made him its 15th SFWA Grand Master, Grand Master in 1997, and the EMP Museum#Science Fiction Hall of Fame, Science Fiction Hall of Fame inducted him in 2001, its sixth class of two deceased and two living writers. His most notable awards included Hugo Awards in 1963 for ''The Dragon Masters'', in 1967 for ''The Last Castle (novella), The Last Castle'', and in 2010 for his memoir ''This Is Me, Jack Vance!''; the Nebula Award in 1966, also for ''The Last Castle''; the Jupiter Award (science fiction award), Jupiter Award in 1975 and the ...

Solar Sail
Solar sails (also known as light sails and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large mirrors. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s. The first spacecraft to make use of the technology was IKAROS, launched in 2010. A useful analogy to solar sailing may be a sailing boat; the light exerting a force on the mirrors is akin to a sail being blown by the wind. High-energy laser beams could be used as an alternative light source to exert much greater force than would be possible using sunlight, a concept known as beam sailing. Solar sail craft offer the possibility of low-cost operations combined with long operating lifetimes. Since they have few moving parts and use no propellant, they can potentially be used numerous times for delivery of payloads. Solar sails use a phenomenon that has a proven, measured effect on astrodynamics. Solar pressure affec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbital Ring
An orbital ring is a concept of an artificial ring placed around a body and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity. For the Earth, the required speed is on the order of 10 km/sec, compared to a typical low Earth orbit velocity of 8 km/sec. The structure is intended to be used as a space station or as a planetary vehicle for very high-speed transportation or space launch. Because the cable is spinning faster than orbital velocity, there is a net outward force that is countered by internal tension within the cable. This resists any attempt to bend it and allows it to carry loads. In typical conceptions, a motorized platform is placed on the cable that runs in the opposite direction at the speed that makes it appear stationary above the ground. Above Earth's equator, a platform running at 9.5 km/sec in the direction opposite the cable will appear stationary and allow a cable to be lowered to f ...

Launch Loop
A launch loop, or Lofstrom loop, is a proposed system for launching objects into orbit using a moving cable-like system situated inside a sheath attached to the Earth at two ends and suspended above the atmosphere in the middle. The design concept was published by Keith Lofstrom and describes an active structure maglev cable transport system that would be around 2,000 km (1,240 mi) long and maintained at an altitude of up to 80 km (50 mi). A launch loop would be held up at this altitude by the momentum of a belt that circulates around the structure. This circulation, in effect, transfers the weight of the structure onto a pair of magnetic bearings, one at each end, which support it. Launch loops are intended to achieve non-rocket spacelaunch of vehicles weighing 5 metric tons by electromagnetically accelerating them so that they are projected into Earth orbit or even beyond. This would be achieved by the flat part of the cable which forms an acceleration tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Transport
Spaceflight (or space flight) is an application of astronautics to fly spacecraft into or through outer space, either human spaceflight, with or uncrewed spaceflight, without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in Earth orbit, orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflight operates either by telerobotic or Autonomous robot, autonomous control. The more complex human spaceflight has been pursued soon after the first orbital satellites and has reached the Moon and permanent human presence in space around Earth, particularly with the use of space stations. Human spaceflight programs include the Soyuz programme, Soyuz, China Manned Space Program, Shenzhou, the past Apollo program, Apollo Moon landing and the Space Shuttle programs, with currently the International Space Station as the main destination of List of human spaceflights, human spaceflight missions while C ...

Spacecraft Propulsion
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. Several methods of pragmatic spacecraft propulsion have been developed each having its own drawbacks and advantages. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south station-keeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success. Hypothetical in-space propulsion technologies describe the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SkyTran
Skytran (stylized as skyTran) is a personal rapid transit system concept. It was first proposed by inventor Douglas Malewicki in 1990, and is under development by Unimodal Inc. A prototype of the skyTran vehicle and a section of track have been constructed. The early magnetic levitation system, Inductrack, which SkyTran has replaced with a similar proprietary design, has been tested by General Atomics with a full-scale model. In 2010, Unimodal signed an agreement with NASA to test and develop skyTran. skyTran has proposed additional projects in France, Germany, India, Indonesia, Malaysia, the United Kingdom, and the United States. System details To minimize maintenance and make switching on and off the tracks efficient at high speeds, early versions of the system proposed using the Inductrack passive magnetic levitation system instead of wheels. Passive maglev requires no external power to levitate vehicles. Rather, the magnetic repulsion is produced by the movement of the ...

Teleportation
Teleportation is the hypothetical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction literature and in other popular culture. Teleportation is often paired with time travel, being that the travelling between the two points takes an unknown period of time, sometimes being immediate. An apport is a similar phenomenon featured in parapsychology and spiritualism. There is no known physical mechanism that would allow for teleportation. Frequently appearing scientific papers and media articles with the term ''teleportation'' typically report on so-called " quantum teleportation", a scheme for information transfer which, due to the no-communication theorem, still would not allow for faster-than-light communication. Etymology The use of the term ''teleport'' to describe the hypothetical movement of material objects between one place and another without physically traversing the distance ...

Slidewalk
A moving walkway, also known as an autowalk, moving pavement, moving sidewalk, people-mover, travolator, or travelator, is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction. History The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois, in the United States as ''The Great Wharf Moving Sidewalk'' and was designed by architect Joseph Lyman Silsbee. It had two different divisions: one where passengers were seated, and one where riders could stand or walk. It ran in a loop down the length of a lakefront pier to a casino. Six years later a moving walkway was also presented to the public at the 1900 Exposition Universelle in Paris as the ''Rue de l'Avenir''. The walkway consisted of three elevated platforms, the first was stationary, the second mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
