The engine produces thrust through the expansion of a super-heated 350,000°C plasma, an ionized gas that can be accelerated to produce thrust. The gas could be one of many, including water vapor. It is turned into plasma for thrust by a radio frequency antenna. The force generated by the thruster is low, but very efficient.
