I wasn't very clear. I know Marinov's original motor works, but what I thought might be "real" and anomalous is the mercury-wetted version with loose bearings. It's one of those rare alt-sci inventions I strongly suspect will turn out anomalous, and could be used to demonstrate the harm that scoffers do to science, but on my own list of tasks it's way too far down. One thing about self-excited electric motors of all kinds: they work independantly of voltage polarity. That's why they're called "AC/DC" motors. Self-excited homopolar generators DON'T put out one polarity for CCW and a different polarity for CCW. Instead the polarity depends on initial microscopic currents (much like Kelvin Thunderstorm Device with microscopic voltage.) If Marinov's motor runs in the direction of its initial spin, it could still be a Homopolar Faraday motor of the self-excited type. If spun fast and shorted out, it might even become a Homopolar self-excited generator, and produce an enormous current. (((((((((((((((((( ( ( ( ( (O) ) ) ) ) ))))))))))))))))))) William J.
