Well, if you do get your perpetual motion machine to work, be sure to let the world know :-)
Also, friction is about the least efficient way of creating heat that I can think of offhand. Assuming that you can get your "gravity motor" to work, you'd be far more efficient replacing the electric motor in a fridge with it. Or save some work, and just buy a few PV panels to run the fridge &c.
