ET3 is literally "Space Travel on Earth". ET3 is silent, low cost, safe, faster than jets, and is electric.
Car sized passenger capsules travel in 1.5m (5') diameter tubes on frictionless maglev. Air is permanently removed from the two-way tubes that are built along a travel route. 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 2 hours.
