Hi Turion,
Thanks for sharing the report. Just a few quick comments and questions.
Did you verify the frequency / RPM ratio?
I don't care 24V or 36V input to the motor. What is needed is the exact measured voltage and current at the motor input for each data point. With the DC motor, that will give the exact input power in watts.
I don't care about light bulbs. What is needed is the measured total output real power in watts. Since the generator output is AC, the real power in watts requires measurement of RMS voltage, RMS current and PF (Power Factor or phase angle of current to voltage). If you're anywhere near 60Hz sinewave, a killawatt meter gives all this info for about $25 instrument. It should be verified with a scope. Option would be to rectify the output to DC and measure average volts and amps at the load. You only drop about 2V for a FWBR. Of course input and output must be measured simultaneously.
That's all that is needed. Input power and output real power in watts.
Nameplate ratings, like "300W" bulb, mean nothing. 12V battery means nothing. Proof needs actual measurements.

bi
