Is this the Smith/Kapanadze secret ?

I don't have meters so can do measurements by taking power only. If caps are removed effect is gone.

During this measurement the goal is not to transfer power or induce voltage at W3 but to transfer power between W1 and W2 or induce voltage in W2 by supplying W1 with AC.

I can say that my caduceous winding is pretty good so I don't think it is leakage flux. Q factor is about 10 frinkinhoivens.

Curious units
The near field of even perfectly wound coils can be significant because of the Biot-Savart law, so they can surprise you.  The whole purpose of this measurement without caps is to determine how much interaction happens between W1 and W2.

Just to get on the map, you are saying that there should not be RLC circuit in circuit like figure 3 (no resonance point), only RC hence no power transfer to W3.

Not that there should not be, but that there cannot be an RLC circuit if L is zero.  A coil with no self-inductance behaves like a resistor.

If there is resonance point only then there can be power transfer to W3 ?
Well, when using caduceous style winding I got power transfer to W3 which should not happen.

Power transfer to W3 by near-fields is not surprising.  What would be surprising is if you had power transfer between W1 and W3  as well as W2 and W3 but no power transfer between W1 and W2.

Removed caps, AC into W1 and there is power in W2, how could there not be dont know. Watt meter showed about 30 watts when load was connected and about 22 watts without load. When caps are in place watt meter showed 33 watts with or without load. If only I could make a proper tank circuit in my step up trafo then I might see something usefull. But it leaks if I push it too hard. I got maybe 5 volts but lots of amps, should there be more volts to make a better tank, any ideas anyone ?

What I think I see is that there is power transfer between W1 and W3 only, that is the whole idea. When load is taken then it makes two back EMFs 180 degrees apart which cancel out. There should be two currents in the primary, lots of power in W1 but little power in W2. Is this what is really going on I don't know and any help to solve this would be nice. I don't have any decent equipment to go further, I might get lucky with my stepup tank but don't count on it.

In Steinmetz times they tend to understand that EMF is a force like name suggest. In other thread I posted the explanation which is Newton third law , everywhere. Does it ring for you ? Famous "ring twice" notice by Ed Leedscalnin. You have it right Jack.

Sorry,I cannot answer your questions. I can only describe simple experiment which could be done and is today possible because there is a method to produce thin strips of high power neodymium magnets and thin strips of superconducting material. Just make light powerful magnet strip and cover around by superconducting shield (or maybe the opposite way) . Then put it in low temperature (to allow superconduction and Miller effect) . It has to be really light but as light as to be able to be pulled by Earth field (with a strength of magnetosphere as supposed by science). If it would levitate then it would be a proof magnetic field is responsible for gravitation.

Consider a resonant tank circuit, when tuned current at certain frequency does not go through. When power is collected using secondary coil back-EMF is induced to source which drives tank circuit off resonance lowering its impedance (inductive reactance) and more current begins to go through it, power gets used. When using high frequency then amount of wire used in secondary can be less and if such a short secondary coil is shorted then it has no effect on primary side. There is no DC resistance hence it has no effect, I have tested this several times using different coils and also Utkin explains it well. But the instant there is load Mr Lenz kicks in and resonance is destroyed in the tank and current begins to get through.

My idea is simple. What if we could create a second back-EMF which is exactly opposite (180 degrees) to first back EMF ? Then those two back EMF would cancel each other out and resonance is not destroyed. As resonance condition stays tank circuit blocks current coming from source and power is not used. Only reactive power that is running in the tank is copied to load.

Look at the schematic picture, there is tuned tank circuit and CW wound coil, then connected to it is second coil wound CCW and series capacitor to get series resonance. Secondary then goes over two primaries. When there is no load taken, the tank circuit is 'hot', it has all power there as reactive power and it effectively blocks current flow at the resonant frequency. The second primary is 'cold', it is only delivering little power to tank circuit. Next load is connected, what happens ? There are two primaries so both gets back-EMF into them. But now primaries are in opposite direction so we will get a 180 degrees phase shift and back-EMFs cancel each other out.

Input has to be sine wave, as tank circuits can only block sine waves at its resonant frequency. Any attempt to use spark gaps, half sine or square waves at source will not work when using this schematic.

Kind a simple idea isn't it, anyone care to take a closer look or has this been tried before ?

The thing will immediately go into balance and the momentum is dead. the result is nothing.

oops sorry, I pressed Post too fast, this effect is of course no Miller but Meissner
