ABSTRACT:
An ultra high-speed transportation system comprising a prepared tube for moving people and cargo in vehicles being propelled by a variable-speed motor ultra high-speed air stream generator, a continuous moving ultra high-speed air stream of air within the prepared tube that is end to end, or continuous without end, with a series of load-unload stations that do not have the stream moving through the station. The air stream is bypassed around the station back into the main transportation tube, so as not to interfere with loading and unloading of the vehicles. The vehicle when traveling in the tube is kept from the tube wall and kept in the approximate tube center by the force of the moving air stream, having to move around and past the vehicle that fills only about two thirds of the tube's opening, because the air stream is moving at a higher rate of speed than the vehicle. In ground level where the transportation tube direction in elevation changes up or down, to keep the gravitational forces from becoming intolerable on the passengers, an air stream generator is used to bypass some of the air stream to lower the vehicle speed. In movement of non-living cargo optimum speed is used, disregarding the G. forces.
