ET3 Global Alliance
ET3 Global Alliance is an American open consortium of licensees dedicated to global implementation of Evacuated Tube Transport Technologies (ET3). It was founded by Daryl Oster in 1997 with the goal of establishing a global transportation system utilizing car-sized cargo and passenger capsules traveling in 1.5m diameter tubes via frictionless superconductive maglev. Oster claims that the ET3 system will be able to provide 50 times the amount of transportation per kilowatt-hour compared with electric cars and electric trains, costing only 20 cents' worth of electrical energy to get up to . ET3 claims that initial systems would travel at the speed of for in state trips, and later will be developed to 6,500 km/h (4,000 mph, hypersonic speed) for international travel that will allow passenger or cargo travel from New York to Beijing in 2 hours. The initial proof of concept system could be built in as little 3 years for operational transport. 1997–2007 Southwest Jiaot ...

IP Address
An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication.. Updated by . An IP address serves two main functions: network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as in IPv4, and in IPv6. The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., , which is equivalent to the historically used subnet mask . The IP address space is managed globally by the Internet Assigned Numbers Authority (IA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Transport
Sustainable transport refers to ways of transportation that are sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport (roads, railways, airways, waterways, canals and terminals). Transport operations and logistics as well as transit-oriented development are also involved in evaluation. Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental and climate impacts of the system. Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. The majority of the emissions, almost 97%, came from direct burning of fossil fuels. In 2019, about 95% of the fuel came from fossil sources. The main source of greenhouse g ...

Hypothetical Technology
Hypothetical technology is technology that does not exist yet, but that could exist in the future. This article presents examples of technologies that have been hypothesized or proposed, but that have not been developed yet. An example of hypothetical technology is teleportation. Artificial general intelligence Artificial general intelligence (AGI) is a hypothetical artificial intelligence that demonstrates a human-like ability to learn. AGI is a machine which could do all human activities with the efficiency of a machine. It is a primary goal of artificial intelligence research and a common topic among science fiction writers and futurists. Artificial general intelligence is also referred to as ''strong AI'', or seAdvanced Human Intelligencewhere he defines strong AI as "machine intelligence with the full range of human intelligence." ''full AI'' or one that has the ability to perform "general intelligent action". AGI is associated with traits such as consciousness, sentience ...

Vactrain
A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to . This is 5–6 times the speed of sound in Earth's atmosphere at sea level. 18th century In 1799, George Medhurst of London conceived of and patented an atmospheric railway that could convey people or cargo through pressurized or evacuated tubes. The early atmospheric railways and pneumatic tube transport systems (such as the Dalkey Atmospheric Railway) relied on steam power for propulsion. 19th century In 1888, Michel Verne, son of Jules Verne, imagined a submarine pneumatic tube transport system that could propel a passenger capsule at speeds up to under the Atlantic Ocean (a transatlantic tunnel) in a short story called "An Express of the Future". 20th century The vactrai ...

Swissmetro
''Swissmetro'' is a proposed Swiss transportation system based on vacuum-train (also known as vactrain) technology. It was invented by Swiss engineer Rodolphe Nieth in 1974 and it is presently being promoted and developed as SwissMetro-NG ("NG" for New Generation). Technology The Swissmetro project was presented in a special report by Rodolphe Nieth, Martin Steiger and Jean-Francois Braillard in 1980. It proposed vehicles travelling at very fast speeds in a network of underground tunnels. Rolling resistance was eliminated with magnetic levitation, as in the Transrapid of Germany and air resistance was reduced by lowering the air pressure in the tunnels to around 10% of the normal atmospheric pressure. Propulsion was electrical (linear motors). The travel time between Bern and Zurich would have been reduced from around 1 hour by intercity train or motorcar to a mere 12 minutes with Swissmetro. Objectives The objectives were to connect Swiss urban centres with a fast, modern, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperloop
A hyperloop is a proposed high-speed transportion system for both public and goods transport. The idea was picked up by Elon Musk to describe a modern project based on the vactrain concept (first appearance in 1799). Hyperloop systems comprise three essential elements: tubes, pods, and terminals. The tube is a large, sealed and low-pressure system (usually a long tunnel). The pod is a coach pressurized at atmospheric pressure that runs substantially free of air resistance or friction inside this tube using magnetic propulsion (in some cases augmented by a ducted fan). The terminal handles pod arrivals and departures. The Hyperloop, in the initial form proposed by Musk, differs from vactrains by relying on residual air pressure inside the tube to provide lift by aerofoils and propulsion by fans. The hyperloop has its roots in a concept by George Medhurst in 1799 and subsequently developed under the names pneumatic railway, atmospheric railway or vactrain. Elon Musk renewed in ...

High-temperature Superconductivity
High-temperature superconductors (abbreviated high-c or HTS) are defined as materials that behave as superconductors at temperatures above , the boiling point of liquid nitrogen. The adjective "high temperature" is only in respect to previously known superconductors, which function at even colder temperatures close to absolute zero. In absolute terms, these "high temperatures" are still far below ambient, and therefore require cooling. The first high-temperature superconductor was discovered in 1986, by IBM researchers Bednorz and Müller, who were awarded the Nobel Prize in Physics in 1987 "for their important break-through in the discovery of superconductivity in ceramic materials". Most high-c materials are type-II superconductors. The major advantage of high-temperature superconductors is that they can be cooled by using liquid nitrogen, as opposed to the previously known superconductors which require expensive and hard-to-handle coolants, primarily liquid helium. ...
