The picture is a bit dark on my laptop screen. But i think i got it. your using the drive shaft to turn to rollers that are runing in a milled track. Very nice.
I came accross this other similar idea that seems pretty cool as well using friction to drive a worm type flywheel. They used a Threaded rod to move a square pipe along the rod that turned the flywheel. Saw it posted on CN forums will dig it out. To stop the square tube turning the placed a second roller on the other side of it similar to your drive shaft sitting in the middle of two rollers.
