@Kevin: If you didn't see my encouragement in the other thread, let me reiterate here--by all means do it an hour at a time if you have to and please post updates!

Ok, here's what I see happening in this little circuit.


What follows is my take on what happens during one cycle. When Mr. Bedini said that his monopole motor was an attraction motor, something just didn't sit right with me. But, of course, now I realize he was right:


With no current flow in the circuit, a rotor magnet is a attracted to the coil core and moves toward it. This induces a tiny current in both coil wires. Electrons flow from the back of the trigger coil to the front, through the resistor and diode and back the the rear of the trigger coil. If enough current is present, it also flows through the base of the transistor and into the power coil.


Once the base of the transistor has current flowing through it, current from the battery flows from the negative terminal of the battery, through the emitter of the transistor and out the collector, then through the rear of the coil and out the front to the positive terminal of the battery. At this point, the current flowing through the coil creates a strong magnetic field, temporarily magnetizing the coil core with a north pole in front and a south pole in back. This gives the rotor magnet a good strong kick in the direction it was traveling.


With the rotor magnet kicked away, there is no more induced current in the coil. Current flow at the base of the transistor stops and so the current path from the battery, through the transistor, is interrupted. At this point the magnetic field in the coil collapses and, coupled with the brief amount of time that the coil was energized by the battery, a radiant event occurs in the coil accompanied by a high amount of voltage appearing with no current. As the next magnet on the rotor comes in, it is attracted to the coil core and the cycle repeats itself.

Now this is what I'm seeing, but I could be flat out wrong. I'm just groping for an explanation of how this little thing works. One counterexample is in the Bedini/Beaden PPA where there is a picture of a waveform showing current in the trigger side of the circuit, one which strongly suggests a type of "ringing" oscillation as the current ramps up. Which means that my explanation, while plausible, fails to explain the ringing oscillation of that picture. Obviously, there are still some gaps in my knowledge here.
