Response to paulkienitz (Reply #44)

47. Their paper is pretty low on specifics

The only number they give is the microwave frequency (935 MHz). Another paper says, "The near term focus of the laboratory work is focused on gathering performance data to support development of a Q-thruster engineering prototype targeting Reaction Control System (RCS) applications with force range of 0.1-1 N with corresponding input power range of 0.3-3 kW."

I'm pretty sure that their claim is not just making a "microwave thruster." Which I guess is why they're happy to claim more thrust than your calculation based on the momentum of a microwave photon would predict.
