Maybe that understanding was off a bit, I said that was months ago when I knew less. I've since reread all the patents, some several times.
But a sound point is, dozens of people have replicated the alternator set up with impressive gas production. This is Stan's own 'improvement on the alternator' designed directly to overcome some inefficiencies of the alternator and to make it specifically useful for the purpose of powering the WFC.
You have seen stock alternators, rewound high voltage alternators, and then this is the next step from that. Of course it is going to produce gas, and it is going to do it a lot better. This is what it was designed to do.
