Awww, Steve, I wanted to see the overunity device / EMP generator / water deioniser / fuel efficiency product / whatever it was! And I think I have a spare thronomister or two in the shed, along with my NOS flux capacitors.
It's OK, we have nothing to fear from this invention. He's using a transformer from a microwave oven. The spark is only a few millimetres long. He doesn't seem to have discovered that electricity doesn't acquire its magical properties until the spark is at least two inches long. And there is no rotating disc, and no moving magnets! None at all. I'm very disappointed.
Actually, I don't even think that invention is pseudoscience. Perhaps it could be classified as pseudo-pseudoscience
