Abstract: A transportation system for supersonic travel including a conduit containing an atmosphere that exhibits high aerodynamic tunneling performance, or high gas efficacy, and a vehicle designed to operate within the conduit. The vehicle traveling within the conduit along a support and guide structure that is complementary to a support and guidance system of the vehicle. The vehicle being propelled through the conduit via a propulsion system that includes contra-rotating propellers.

Abstract: A transportation system having a tube containing hydrogen gas and a vehicle designed to operate within the tube. The vehicle breathes hydrogen from the tube to power fuel cells in order to produce power. The vehicle is suspended above the tube on a low-friction layer and is propelled through the tube via a propulsion system, such as contra-rotating propfans.
