Anybody try it with a pulse generator instead? 

The problem with the ordinary pulse generators is that they supply too low a current to saturate the core. The ones with high current output are prohibitively expensive. Otherwise, the pulse generator supplies the needed form of the signals with no additional elements. Using a pulse generator with a DSO and a proper processing of the data is what is needed to understand whether or not these motors are OU. The only correct methodology I've seen so far in assessing the OU is by Steorn. They need to drive the motor with a pulse generator, though, for some additional measurements to make their conclusions definitive. No need for calorimetry. Just some more electrical measurements in additions to what they've done, using a pulse generator, to finalize their findings of OU. Everyone else trying to reproduce the OU property of these motors (including all Adams and Bedini fans) should necessarily do these careful measurements as well. Just seeing that motor spins or trying to charge batteries isn't enough, unless a self-sustaining run of the motor is demonstrated.

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.

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.

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

Thanks Omni, watching it now
