Pressure-driven magnetically-coupled conveyance

This invention has the ability to provide the initial acceleration necessary for spacecraft to attain earth orbit without use of traditional rocket propellants. The invention also has the ability to provide an alternative means of ground transportation without the direct use of fossil fuel. The invention utilizes a pressurized, nonmagnetic tube to accelerate and translate a piston. The piston is magnetically coupled to a conveyance, which travels along the outside of the tube. The conveyance, in turn, can be either a spacecraft or a vehicle suitable for ground transportation.
