Gray Voltage doubler circuit
So, you see the need for a voltage doubler also, Interesting. I'm sure you have read where one of Gray's referenced patents is by Phinney US#3,619,638. This is also a voltage doubler circuit that explains the need for two power supplies. I'm sure there are other designs that would work if the components can survive the huge electrostatic harvest pulse.
In the pulse motor, Cole didn't need his primary voltage doubled - his autotransformers stepped up the voltage to what ever he needed. What he desperatly needed was a means to discharge the main storage capacitors at a very specific rotration location on the shaft so that his electromagnets were in the right position to do their thing. He was going to have to switch 400 - 600 ampers for a duration of about 11 miliseconds. That kind of current would destroy a rotary contact in a few hours of continuous operation. So, he latched onto the Phinney circuit. Hackenberger attempted to develop the "Converter Element Switching Tube" to do the same job with fewer wires. I think this approach finally proved to be a a failure. By mid 1976 he removed them from his EMA6 motor.
Did you know that Richard had the opportunity to build the last Gray motor in 1979 - 1980. It was 8" in diameter and called "The Blue Motor" It was built in Dodge City, KS. He might have finally figured out what he had over looked in the design of the EMA6. Gray and Hackenberger slipped away in the middle of the night and took the motor with them - that their funding source had paid for. Hackenberger died right after that escape. Gray hid out in San Dieago until he found another funding source. He then set up shop in Canyon City, CA under a fake business name. He then hired yet another technician to get this new motor to work right. And so the story continued for another decade.
The strike method you mention for HID arc ignition sounds inhteresting also.
Don't worry about your education, its only do you some good if you are going to do a lot of classical work. When you deal with "out of the box" technologies it is inspiration that is far more important. After that comes gumption and stick-to it-ness.
