exaustless space propultion

pucture a pinwheel.  now have a motor spin it.  in space, the handle will rotate around the wheel (equal force on both the spinner and spinee).  now imagine the handle has another pinwheel on the other end of it, and it spins, too, switching between accelerating it and the other wheel if neccacary.  would it not be possible, in this fashion to move a vehicle forward in space?

actually, the reason  brought that up was both ordinary matter and light react with matter pretty intensly.  neutrino's don't nearly as much, meaning the exaust would probibly be less-harmful.  just that generating neutrinos presents an issue right now.
