Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Thane,
I see.
And how did now the Dr. Zahn demo work out ?
Is he still pondering about it or is he not anymore involved ?

What was his latest words about it ?

Just: I don?t know what is going on ?
Pretty lame for such a Dr.Dr. Prof.....

It seems, he was only interested in your money...


Dr. Zahn it appears was put off by the newspaper angle.
We tried very hard not to push him too far too fast but we did not account for the Toronto Star spotlight all 14 minutes of it.
So now we are off to NASA and we will see what comes of that.

One step at a time.

I have probably missed if you mentioned but let me ask what happens to the motor consumption when you start loading output coil 2, gradually towards a short circuit? I mean Test case 2 when you have the unloaded 177.7V on coil 2.

The system speed gradually increases as the resistive value approaches 0 ohms from an open circuit - the slip angle between the rotor and stator decreases and the stator power draw decreases..

Hi Thane,

Sorry that I considered your two recent diagrams when I answered and that did not include the magnetic coupling through the shaft...  as Steven just pointed out to me.  (Thanks Steven!)  So I will ponder on this further on...

I would like to confirm what I quoted above: So in Test 2 all the coils are shorted except coil 2 and the speed just increased and already got stabilized,  now the unloaded coil 2 output is 177.7V and from now on you start loading coil 2 resistively towards 0 Ohm, the already increased speed starts increasing and gets even faster?  while motor power consumption further decreases from the value it had when coil 2 was yet unloaded?  Please confirm this,  sorry for not fully understanding how you meant but these are important details.

Thanks,  Gyula

Hi there Thane have you ever seen my 'no-load generator' video?
Here it is:
http://www.krystyna.nl/Machine/RevUpUnderLoad.wmv

that shows a generator loaded with a 50watt 12v car bulb and indeed under load (or direct short) there is a very considerable increase in rpm. (and thus a drop in motor amp draw) The motor is a ?universal motor? from a washing machine powered by a variac.

This accelerating effect does give the feeling that lenz is ?overcome? but it is not so. The effect is only there when one uses ?bad cores? with lots of eddy current and hysteresis losses. In this generator solid steel cores are used and I tell you in only 1 minute they are 70+ degrees (Celsius) hot, and I?m not joking. But the main problem is that these bad cores don?t seem to be able to give a bigger output then the losses they have. So the solid steel cores were replaced with good silicon steel laminations, but you guessed it, the accelerating effect is now gone.

So you can kinda say it like this. If you have a core with lots of core losses, Lenz will fight them and cause less drag on the rotor under speed (but only up to a balance between the two) but due to the bad core you can forget any o.u potential. So you say let?s use good cores then, like silicon steel or metglass? well you now have the potential of real good output? but unfortunately the no load effect is now gone. So again nature has found a way to put ?it? just out of our reach.

The deal is that you really can't tell these systems until you use proper low loss lamination (easy to obtain from an old microwave oven transformer) and start cranking some real watts. It really matters a whole lot between solid steel or laminations. So if I were in your shoes I would make your systems so that you get at least like 100+watt out of your 200+watt input, and see if the no-load effect is still there.

Kind regards,
Steven

MainPower is right on.   Dr Zahn's request needs to be carried out.

If I had discovered a strange phenomena, I would investigate it rigurously.  I would ask things like:  where are the forces created? Is there a breaking action that's reducing?  How are the phase angles changing?   How is the flux linking.  I would hook sensors all over that thing.

So let's not forget the main "invention", or rather discovery.   It's the "motor speed-up" phenomena, not the toroidal transformers!

All this parallel magnetic path stuff is old news.  Lots of people have wasted time and money exploring this.  They don't work as overunity devices, maybe as something else perhaps.  These devices are enticing because people think in simplistic terms about magnetic flux.   For the record, flux will shoot out of that ring when you apply current to the two coils which are in opposition. Early motor designs used this.  So you don't violate reciprocity (which is what people are trying to violate, not Lenz's law)

So my advise is to focus on trying to understand the speeding-up effect of the motor, it is this phenomena that has raised eyebrows.

have achieved very high rotation rates of 1803 rpm for free nanowires and 445 rpm for nanowires with one-end fixed at 10 V and f = 80 kHz as shown in Fig. 2a. We have detected no limitation in the rotation speed up to 1800 rpm, beyond which our video system with 30 frames per second could not accurately track the rotation. The value of ω also depends on the frequency of the AC voltage. As shown in Fig. 2b, at VAC = 2.5 V and 5 V, the rotation rate of a free nanowire increases sharply below 50 kHz before leveling off and then decreasing slightly fro
