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? 

You need some sort of exhaust for propulsion in space. Period.

Keep in mind that the exhaust can be just light. You can strap a huge laser on your shuttle and turn it on, and that will cause you to move; the reason is because light has momentum. It's an exhaust because you're throwing that energy out the back of your shuttle.
