Using an NPN transistor instead of a reed-switch ...

Anybody who studies Bedini motor should do their power measurements the way Steorn do it. I haven't seen anything close to that level of study so far. Shining lamps and charging batteries, let alone using average or efficient voltages and currents don't cut the mustard as far as OU is concerned.

That's true i suppose the figures may be kind of muddy unless there's a huge OU difference, what with chemicals etc ...

I hadn't thought of it like that before, thx:)

Do you have a handy link to the Steorn method ?

I think they took down their youtube vid with the demo. In essence what they do is use an integrating scope which multiplies the momentary values of I and V and subtracts the momentary Ohmic heating value I^2R. Then the results of this arithmetic are integrated over time and displayed directly on the scope screen. That's for the input energy. For the output energy they use a pickup coil, short circuited, and there they measure the momentary Ipc^2Rpc, where Ipc and Rpc are the pickup coil values of the current and resistance. Then, again, this is integrated over time and displayed directly on the screen of the scope. In this way they are able to demonstrate at once that the slope of the output curve is three times the slope of the input curve, that is, that the output power is three times the effective input power. Wish you or anybody playing with these motors could do that measurement on your rig, hopefully powering it with a pulse generator. That's a start. As I said, there should be some additional measurement carried out as well.

OK thanks for that Omni, when i get my scope i'll attempt to replicate that measurement method.

One more thing, is a pulse generator the same as a frequency generator ? Can they do/are they the same thing ?
