@Group,

Circuit is running from a lead acid battery, 12,23 V.  Without feedback the circuit uses 0,15 A.
When I connect the feedback the input usgae drops to 0,08 Amp. Measurements is done
with a moving Iron analog meter and is approximately only. More measurements must
be done before any certain conclutions. But it seems to me that the system is capable of
coupling magnetic flux from the input core to the output core by using a short circuit coil.

BTW: The R1 is only needed to start the circuit so I used 580K.

Groundloop.

[EDIT-1] The moving Iron amp meter affects the circuit. When I remove the amp meter the input current increase a lot.
            To get the amp down again I just connected an air core coil in series with the plus on the battery.
            Now the circuit runs a very low input amp.

Hi Groundloop,
Impressive work! I wish I had even half your knowledge.

When you say "connect the feedback" above, do you mean closing L3?

Are you going to disconnect L2 from the circuit later to measure output or are you checking by looking at the effect of closing L3 on the input current?

Lastly, do you have any specific questions you'd like us to ask Thane that would help you?

Hi Groundloop,
well done.
With using an moving iron ampmeter you can not be sure,
if it is + 80 mA input current or minus 80 mA input current as
these meters also show negative currents as positive currents.

So try to get a real analog coil ampmeter, so you will know for sure.
Many thanks and looking forward to your new tests.

Regards, Stefan.

Steven,

No, I connected and disconnected the L3 coil. Seems to me that I can loop back
approx. 50% of the total power back to the battery. When I open and close the L2 coil I can also see the input going up and down.

I am going to remove the feedback and do a measurement on the output to see how much I can get. I will also play with the L2 coil and see if I can get some power from that coil also.

I have one question you can ask: What type of cores and size of cores to use in this setup.

@hartiberlin,

No, it is +80mA FROM the battery because the battery is slowely going down in voltage.

@Group,

Last test today. I reversed my coil so that the core with low Permeability was the oscillator coil and the core with high Permeability was the output coil. I did expect a drop in the performance with less power going back to the battery. That did not happen! I got the same result as before. So my coupling stayed the same and my output stayed the same. The current usage was the same 80mA from the battery. This tells me that there is no difference in performance when I reverse the cores.

For the non tech. out there: I get a 50% feedback to the battery from the circuit.
                                        Same performance regardless of the Permeability.
                                        The magnetic coupling works the same both ways.

So MY circuit does not work as claimed by the inventor. I get NO gain in the output regardless of Permeability issues. This does NOT mean that the inventors circuit does not work. I means that MY circuit does not work. Maybe it is too small and maybe the cores is of the wrong type or size. I must stress that my measurements is preliminary at best due to no high tech. measurement instruments available.

Groundloop,

Very nicely done! If the toroids in this only picture I could find are truly representative of what is required, then maybe it really is the cores that make the difference. Anyways, an awesome piece of creativity in a short time on your part, and if we get some clues from Thane it may be the perfect testing platform!
