A blogger estimates:
The Saturday demo, our sources confide, will be less dramatic - if they can hit 120 percent, or 1.2 watts out for 1 watt in, it'll be a success."
If they can hit 120% I believe they could make the thing self-sustaining. The overhead from friction and a capacitor is small. Very small compared to a heat engine powered by cold fusion would be.
Terry Blanton or some other magnet motor expert can probably tell us what the minimum excess would be to allow a self-sustaining gadget.
