What is wrong with the published circuits?
The energy from the input coils just leaks into the output circuit. So the fields of the permanent magnets are static in time, and do not move from one leg to the other. Performing force experiments with the generator windings in place, would reveal this flaw. However, it seems to have eluded hundreds of experimenters, who failed to use a rigorous methodology when conducting their experimentation. Pulsing the input and output circuits in series is one solution. Well, at least that gives nice oscilloscope shots. But when you try and draw a real load, the waveform collapses. So your method of isolating the input / output circuits needs to be more robust, and may require a more physical approach. Thats a strong hint.
