I posted this info in another thread but it got dropped so ill put it back up again. A few observations i made while experimenting with this are the following:
The coil behaves exactly like pulsing a bedini coil, you need to adjust pulse duration to hit the resonant impedance points in the coil. When you do this, you get more output and less drag on the prime mover. You can also use a variable capacitor in series with the short to hit the sweet spot. Or just adjust your rotor speed. You will need something to turn your generator wheel at a constant speed to play with these variables and notice the effects, and it may be hard to adjust pulse duration with reed switches, but you could do it with 2 of them.
