"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."
Dopo anni di critiche dalla comunità scientifica dovute al fatto che il propulsore in questione violerebbe la legge di conservazione del momentum, la NASA ha avviato una ricerca approfondita sull'argomento e alla 50ima Joint Propulsion Conference in Cleveland ha presentato i risultati dello studio:
"Test results indicate that the RF [radio frequency] resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and, therefore, is potentially demonstrating an interaction with the quantum vacuum virtual plasma,"
