Since this artifically created South pole in the form of the moving bubble floating on the North pole face can easily move, it can easily be made to vibrate, possibly over a contained area. If you place a coil of wire around the bubble, creating a constained area, you could push the bubble back and forth in a controlled fashion with very small magnetic impulses. Now, if you place another coil of wire, in such a way that the bubble edge moves back and forth across this coil, then you will induce a changing current that can be extracted. If the coil tapping the energy is bifilar, it would not suffer magnetic repulsions due to back emf. If under load, it would work like a homopolar generator, where the dissipation of produced power for any size load would not increase the energy needed to drive the motor driving the generator.
Resonance is thus necessary to be able to tap the extra energy.
Alan has achieved what appears to be the same magnetic bubble that Don did. I'd like to make, when I asked Donny about the programming of the magnet with the 60cps wave, he said it could be any frequency. Don also said that once a magnet was programmed, you could touch a scope probe to the magnet and you would see a VERY WEAK 60cps wave on the screen. I asked if this could be simply picking up background 60cps from the wall wiring and Don insisted it was not. I did not see this test since we were at the conference and he was just describing it.
