I do not mean to contradict what John and Peter stated. They said that even though we have found a solid state resonance in this Bedini SG (simplified) circuit, it was not designed to work as such, and that other modifications need to be made to optimize the non-rotation resonance variation. They wish for us to focus on this circuit as designed -- rotating wheel powered by input battery causing output batteries to be charged. John also commented that the wave form that Jim reported does not look like the wave form they get when things are operating properly.
That said, I would like to report by way of information that I have observed that on a purely electrical basis, speaking of amps and volts, putting aside the question of radiant energy, I have found that THE CIRCUIT OPERATES MORE EFFICIENTLY IN SOLID STATE MODE THAN IN ROTATION MODE.
The amps IN versus amps OUT ratio is significantly more favorable in the rotation mode than in the solid state mode.
In my present experiment 10.0 (supercharging all the batteries), for example, I am switching between solid state mode and rotation mode, all other things remaining the same. The input battery is the same battery through the duration of the supercharging (with trickle charge when needed to keep it above the 20% discharge level), with five batteries being charged on the output side.
The highest output combination I have been able to get in rotation mode (adjusting potentiometer to find max amps) is 0.37 amps into the circuit, producing 0.08 amps out to the batteries, with the wheel rotating at around 176 rpm. This is a 22% conversion of input energy to output energy (on a purely electrical level, leaving out the question or possibility of radiant energy not being picked up by the meters).
The highest output combination I have been able to get in solid state mode is 0.11 amps in, which produces 0.04 amps out to the batteries being charged. This is a 36% conversion of input energy to output energy.

On a purely electrical level, this shows the solid state charge to be nearly 30% more efficient than the rotation based charge, as would be expected inasmuch as the rotation charge involves energy losses in the rotation of the wheel.
I would like to go through my data and tabulate the input/output amp relationship and see if I can't get some kind of graph produced from the composite regarding electrical efficiency. Of course it is not the plain electrical phenomenon that is of interest to us here. We are after the radiant energy.
Has anyone taken oscilloscope shots from the rotating wheel output? How do they compare to scope shots from the solid state output? Are there harmonic regions where the signal modifies its shape? Or does the signal change gradually with the change in resistance of the resistor in the circuit?

Subject: [Bedini_SG] Re: (posted) Solid state resonance; why
Thanks Sterling, I will update the page when I get the actual SG motor
working. I received my wheel rim today, so I think I have everything
I need to start putting this together.
I understand now why the wheel is necessary. The SS resonance is a
neat little side experiment, but doesn't work to charge the batteries
(at least not in a reasonable time frame as you mention) and does not
do what it needs to do to tap into any quantity of RE
Hopefully I'll have something to show this weekend, or maybe the
beginning of next week.
