Steve,

I have done ONE test so far. I glued two toroid Ferrite cores together and added three coils.
(As shown in the attached drawing.)

My first and only test (so far) showed me NO output in L3 when the switch was open.
When I closed the switch then I got output in L3.

I have NOT compared any input vs. output power yet!

Hi Groundloop,

Does the two ferrite rings have differing permeabilities or they are more or less equal?

If I read correctly, the two cores must differ in permeabilities.

from http://science.blogdig.net/archives/articles/July2007/04/Free_energy_with_magnetic_reluctance.html :

Heins adds that he and his colleagues ?have coupling from the primary to the secondary. The reluctance flux path in the secondary is lower because either the secondary core area is greater or because we employ core material with a higher relative permeability which results in a decrease in reluctance. When the secondary reluctance is lower - back EMF induced flux from secondary coil 1 must follow the path of least reluctance into secondary 2 and not back to the primary. The primary operates only at magnetizing current levels (reactive current only) and does not draw any non-reactive current from the source. The law of conservation of energy for a transformer requires secondary back EMF to be able to mutually couple back to the primary - but if this flux path is higher it will not be able to do so.?

Thanks for the test.

Hi Groundloop,
well done.
Please let us know more about your coil?s setup
and what wire and turn ratio you use.

Also what could help is to rectify the input AC with a diode,
so only thepositive amplitude wave can pass and
then also use a diode at the output coil into the other direction,
so you can decouple core magnet field energizing
from output coil energy extraction.

Many thanks.

Regards, Stefan.

The above also says that the secondary core can be of greater area, though it sounds like Thane used the permeability difference trick. I was thinking more of replicating the toroid setup in video 4 but this certainly seems easier. Thanks for bringing it up Groundloop. I missed it completely.

@gyulasun,

No they are the same. I did not have to cores of the same size but with different materials right now so I
just use two high frequency (HF) cores I had in my box. Will try different cores when I find any.

@hartiberlin,

I have tried to hook the coil onto my SSG. It (the SSG) has a diode on the output. I was able to light up a small light bulb on the output coil (L3) when the middle coil was shorted out. There was no output when the middle coil (L2) was open. I will try different cores (as soon as I find any.) It is a pain in the ass to wind the coils because I have to manually thread the wire through the core for each turn.

My present cores has L1 = L3 = 0,35mm magnet wire 100 turns. L2 =  0,35mm magnet wire 50 turns.
Transformer toroid of 4C6 material has been used. Dimensions: 23 x 14 x 7 mm.
