If so, you can produce a free energy machine by having the quantum thruster move a mass along a track at some finite velocity- unless, as I suspect, the conversion factor makes the quantum drive power/thrust ratio identical to a photon drive. Alas, if it works, it creates thrust no more efficiently than a flashlight. If some energy input can produce some “reactionless” impulse of x N.s/J, is x a constant?

Some of that energy would then be converted into propulsion. What's nice here is that you don't use up the particles that generate the propulsion. So it's not a free lunch, but it is a reusable lunch box. It would still cost energy to move around the magneto-electric particles. Some of that energy would then be converted into propulsion.

Ok, you need some mass, but you just keep using the same mass forever, that's like buying 1 lunch and getting infinite for free, no? I admit I know little about physics, so if someone could explain it in laymans terms I'd appreciate it. If you don’t lose mass, how is it NOT a free lunch?
