Bill Muller was a tall grey-haired man with an apparently high level of vitality despite incessant cigarette smoking. Holding everyone's attention by his forceful personality, he described his invention as a way to make a heavy wheel carry strong magnets past electricity-inducing copper coils without needing to fight the electrical drag force which usually opposes rotation and limits how efficient a generator can be. His wheel didn't have any "stuck" position; it moved freely.
"We have a magnetically balanced flywheel."
In his basement workshop, Bill showed us the beginnings of a permanent-magnet generator.
