Stan said he used some amps... say in the video of running the dune buggy he says 5 volts and 2 amps, 10 watts being applied to the alternator, but that 2 amps never sees the cell, since if he has a rewound alternator with a guess of 300 volts output (purely a guess) then you would only have 33 milliamps into the cell, mybe he has it rewound to even higher voltage, 600 volts would be 16 millimaps... i don't know what you could get out of it.
Also a Permanent Magnet Rotor would eliminate the ability to adjust the power applied to the alternator, thus you would lose control over the output. The alternator needs to be driven at a constant rpm for a constant frequency, while the field windings are powered through the variac.
Steve, you said the magnetization of Hydrogen and Oxygen was all theory, and nobody had tested it... it says in the patent you can do it, maybe that would be a great test to try? are you able to set up to try it, I would love to see what happens!
