Main Question or Discussion Point

Will an Ion generator work in space??

And how does it normalyl work? Does it push upon the ions in the air, or does it actually throw electrons, and this spins the rotor?

This is an Ion generator:

They very much work in space

Ion thrusters work, but you'll need a supply of atoms to be ionized.It's also reallly hard to ionize the atoms before they fly off un-ionized and unaccelerated and yet let the ions escape after they are accelerated. Sticking that mill in a vacuum and providing a high voltage won't do anything. Ejecting just electrons isn't possible, because the entire contraption would get a positive charge, and no more electrons could be ejected.
Ion thrusters need to eject electrons as well as positive ions.
