Hi

I would like someone to tell me why this would not work because I cant see why not. It is so basic that there must be some simple problem with the concept??

Imagine two pairs of fly wheels, one pair at each end of a shaft.(like wheels on an axle) The wheels in each pair spin in opposite directions to each other to cancel out their torque.The fly wheels are able to move along the shaft.

If the set on the right are spinning and the ones on the left are not and we pull them both(both sets) towards the middle ofthe shaft. Would the shaft not move towards the right due to the resistance to movement of the spinning flywheels?? Then, if we brake the wheels on the right and start the ones on the left spinning. Then push both sets back to their respective ends of the shaft...does the shaft not move to the right again?

Would repeating the cycle not create motion that could be used in space??

I would appreciate any comments

Thanks
