QUOTE from website:
A New Concept in Spacecraft Propulsion
Satellite Propulsion Research Ltd (SPR Ltd) a small UK based
company, has demonstrated a remarkable new space propulsion
technology. The company has successfully tested both an
experimental thruster and a demonstrator engine which use patented
microwave technology to convert electrical energy directly into
thrust. No propellant is used in the conversion process. Thrust is
produced by the amplification of the radiation pressure of an
electromagnetic wave propagated through a resonant waveguide assembly.
The principles of operation are shown here:

It looks bogus, but who knows. It would be neat to see an actual
demonstration.
