Ambition is the first step in crossing all scientific frontiers but, unfortunately, it's a game of patience. ET3 is a concept known as the Evacuated Tube Transport Technology. Their slogan is "Space Travel On Earth" and their goal is to build airless, frictionless tubes to provide unbelievably fast transit across the planet. New York to LA in 45 minutes, or around the world in six hours, both sound great for businesses or distanced families, but let's be realistic - it still takes 20 minutes just to catch an MTA bus and California can't even build a railway. As idealistic as this sounds, I think I'll just live vicariously through episodes of Futurama.


"Car sized passenger capsules travel in 1.5m diameter tubes on frictionless maglev. Air is permanently removed from the two-way tubes that are built along a travel route. Airlocks at stations allow transfer of capsules without admitting air. Linear electric motors accelerate the capsules, which then coast through the vacuum for the remainder of the trip using no additional power. Most of the energy is regenerated as the capsules slow down. ET3 can provide 50 times more transportation per kWh than electric cars or trains."


"Speed in initial ET3 systems is 600km/h (370 mph) for in state trips, and will be developed to 6,500 km/h (4,000 mph) for international travel that will allow passenger or cargo travel from New York to Beijing in two hours. ET3 is networked like freeways, except the capsules are automatically routed from origin to destination."


"ET3 capsules weigh only 183 kg, yet like an automobile, can carry up to six people or 367 kg of cargo. Compared to high speed rail, ET3 needs only 1/20th the material to build because the vehicles are so light. With automated passive switching, a pair of ET3 tubes can exceed the capacity of a 32 lane freeway. ET3 can be built for 1/10th the cost of High Speed Rail, or 1/4th the cost of a freeway."


"Prototypes, or production components for all of the individual systems used by ETT exist right now. These components / facilities / materials etc. will be virtually assembled into an ETT system over the Internet. As the real components are assembled virtually, plans and alliances are formed for actual construction."


"Economics and politics will come into play to determine the optimal location for the first systems. Attractive routes will be between major cities, over unpopulated flat, dry terrain, below the latitudes where the ground freezes. (India and China are the most promising places for initial system implementation)."
