Escape Dynamics is also developing a next generation system, which relies on the direct heating of plasmas flowing through aresonant cavity with a weight similar to that of the weight of the heat exchanger in a thermal thruster. The goal of thisdevelopment is to allow operation with specific impulse above 1,500 seconds, leading to propellant mass fraction below 50%,which is comparable to airplanes.
Interesting. But since your power requirements are basically your specific impulse times your thrust that'll up the power they need. Still, electricity is cheaper than rockets.
