Air is permanently removed (evacuated with vacuum pumps) from two five foot (1.5 m) diameter tubes built along a travel route. Car-sized passenger/cargo capsules travel in the tubes on frictionless maglev. Airlocks at stations allow transfer without admitting air. Linear motors safely accelerate the capsules, for most of the trip they coast through the vacuum without using additional energy. Acceleration energy is recovered by using linear generators to decelerate the capsules. ETT is not pneumatic tube transport (PTT) commonly used at drive-up banks. ETT is claimed to be able to accomplish fifty times more transportation per kWh than electric cars or trains because travel occurs without air resistance or rolling resistance.
