I've read this half a dozen times over the last days, trying to understand exactly what you are getting at. I think what you are saying is that you could use the power generated by the wheel to power the thruster, which would in turn spin the wheel. The part I don't understand is why you think this "Wheel Generator" would impart any significant thrust to the wheel. That is, let's say (for the sake of argument), that you needed 1 watt to generate 1 newton of thrust. And, that one newton of thrust could get a wheel spinning at 10 m/s. Now, we hook that wheel up to a generator, and it's capable of generating 1/10th of a watt of energy, but in doing so, obviously comes to a halt without external energy being imparted (because obviously the generator uses up its momentum to generate energy) - but, the energy being created by the spinning wheel (1/10th of a watt), only can get the wheel spinning at 1 m/s. The entire system comes to a halt quickly. I'm not suggesting that the entire idea of a reactionless thruster doesn't have huge holes in it - but it certainly doesn't seem to (at least) suggest that you have a perpetual motion machine.
