Hmmm, someone needs to buy one of the sets of plans (now now, not everyone at once) and see what this "special coil" is. The fact that he was working on a "free energy electrical motor" when he discovered it makes me believe he's a crackpot. However, now that we're on the subject, I have been thinking of a way to achieve over unity using leftovers, vinyl siding, and the engine out of an old Vespa......
