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?

 ok, that makes sense.  thanks.

a rotating body can be considered to have a velocity in the direction of rotation at that instand at a speed equal to, well, the velocity of rotation.  say that theroretically the object could handle the sheer forces involved here (it couldn't).  the object in question would gain mass as it's velocity came very close to the speed of light and never quite reach it, just like any other object.
