I suspect that it is theoretically possible to make a magnetic motor that saps the energy from the magnet, over time demagnetizing it. That energy, of course, came from the initial event that magnetized the PM. Of course, I'm picking nits. All of what you said is true, and for all practical purposes (ie, those involving friction, resistance, etc) one cannot use PMs as a battery. Still, such a motor would go over really well in the over-unity community. -Adam - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
