Plasma-Powered Hovercraft Patent

The patent shown is for an aircraft to be powered off the ground using a plasma technology. Subrata Roy, a University of Florida aerospace engineer, proposes the existing technique of passing a magnetic wave through a conducting fluid can produce a force strong enough to lift an aircraft off the ground. Granted, the example in the patent is only 15 cm, and attempts by others haven’t gone particularly well. But with phrases like magnetohydrodynamics being thrown around, I keep flashing back to the space travel scene in Contact and getting excited. Subrata Roy must be a poet. [WIPO via Ubergizmo]
