STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

The whole idea was, in lack of differential probes, to make the passive probes share the same ground with the generator ground. So, the grounds of CH1 and CH2 meet at the same place where the generator ground is -- to the left of R1. 

Yes, that is ok, I understand.

Thanks, Gyula

Here are some data taken with the new setup. This is a graph of the OU effect as a function of frequency. Note the x-axis scale is logarithmic.

I have to retract the above. You may notice in the last schematic I presented that I'm not measuring the input voltage while redundantly measuring the voltage across the input resistor. I'll post corrected schematics and results later.

@LarryC,

Thanks a lot for the link. I will order some of these and will report the outcome. I have already ordered 1Ohm (0.05% tolerance) shunt resistors and am waiting for them to be delivered. At present I'm using 10Ohm, 1W resistors from RadioShack: http://www.radioshack.com/search/index.jsp?kwCatId=&kw=metal-oxide%20resistors&origkw=metal-oxide%20resistors&sr=1. These should be fine for the conditions of the study. I don't think that using shunts having several Ohms resistance should be of any concern in this specific study because the goal here is not the minimizing of the heat losses. On the contrary, heat losses here are the output, as the correct energy balance requires. As seen, if the energy balance is done correctly overunity is trivially present in transformer-type devices. The last schematic I'm using further optimizes the effect and now, as I mentioned earlier, what remains is to design an appropriate converter. It would allow to have the excess energy of the output to be converted into I and V of a proper form which can be fed back into the input and thus turn the transformer into a self-sustaining device.

Noticed JLN had used a .01 Ohm shunt with a portable Fluke scope in his original Steorn testing. Makes me wonder what Ohm shunt you should be using with your high end scope.

I found this great article to 'Make a shunt resistor' using copper wire at   http://www.reuk.co.uk/Make-a-Shunt-Resistor.htm

It would be prudent to test a few shunt values with your scope before ordering a high price, but more accurate shunt.

Regards, Larry

Can you please also measure Vo, so that we can determine if Vi*Ii = Vo*Io is holding here as written in text books. (This is just to see if there is any major measurement error due to incorrect resistances or scope grounding problems)

I still think that to put the matter to rest, you should put the transformer in a thermos flask filled with oil and with secondary shorted and log the temperature change for an hour.

If the heat generated is more than Vo*Io, you will win a nobel for sure.
