hey, I have a question, it might be really stupid, but I'm probably not as smart as any of you here. Anyway: if you had a sustained plasma field held in place, maybe spinning in a toroidal motion, is it possible to "harvest" free electrons from the field by an anode, and feed it back into the field by a cathode? Kind of like how a fuel cell creates an H+ ion, runs the electron that was stripped through a circuit by the anode, then gives it back later through the cathode to be rejoined with oxygen. Again it may be a stupid question, and there may be no net gains from it, but I was really curious. Thanks!
