Mags, that's what I've been working on, multiple primaries to one secondary. It multiplies the output power (W), just as having many secondaries on one primary divides the power.

I was going to start a thread when I got something looped to work, but who knows when that'll be. I'll just give a synopsis here since you brought up the subject.

It works like eddy currents, just in reverse. Eddies are a good model of what you would get with multiple secondaries on one primary. The latter half of this video is a good demo: https://youtu.be/azsqhKg8hX8 (That's not me BTW)

With 1 plate, the eddies are nearly identical to the input current. The resulting B field of the eddies opposes the B field of the coil, so it levitates. When he breaks it down into 2 plates, the eddy current is now divided by 2. The eddy current in each plate is half as much as if it were just a single plate, so the eddy B field in each plate is also half as much- the coil levitates half as high. When 4 plates are put together, the eddy is divided by 4, so the B field is divided by 4- the coil levitates at 1/4 the initial height.

We all know how eddy currents work, and that laminated cores work better than solid iron bars. This is because the opposing B field is created by the eddy currents themselves, not simply by the inducing B field.

If we try to look at the numbers of what's happening with eddies, just say that we have a transformer with 3 identical coils, 1 as primary with 2 as secondary. All have 1 Ohm resistance.
Say we put 1V on the primary, over 1 Ohm gives 1A, so 1W input
Because the flux is divided by 2, each secondary develops .5A
.5A over 1 Ohm gives .5V per secondary, with a power of .25W
Total power of secondaries combined: .5W

If we run the 2 secondaries in series, we get 1V out, but at .5A, so .5W. If we run the 2 secondaries in parallel, we get 1A output, but only at .5V, so .5W. Either way it's only 50% efficient. Increasing the number of secondaries further divides the output power.

All I'm saying is that with Faraday's laws it's not easy to understand WHY this works, why reducing eddies reduces the opposing B field, even though 100% of power is still being transferred. That's because 1A is still being converted into a B field, and that B field is inducing 1A of current, it's just that 1A is divided into many small currents. And each small current is producing it's own small B field, which is the equivalent of, but not equal to the inducing B field.

Basically, to multiply power just do it in reverse- many small primary coils to one secondary. IMO this is how the Hubbard and other designs work. I could get into how the turns ratios work and things I've figured out, but all this is just theory until I can make a stand alone self-powered generator. Anyways, sorry it's so long, I'm just simple-minded so it's tough to explain.

hey Antijon
Very cool.  What Im contemplating is to have the separate primaries affect the secondary individually, not mixed. Like if we have 2 transformers and each has a 100 turn primary and a 100 turn secondary, but one transformer primary is wound with 16ga and one is wound with 14ga. The sec should react pretty much the same, I think. But if one transformer had say a bifi, 2 parallel windings of 16ag and the other a single 14ag, would there be a difference between a single winding of 16ga vs 2 parallel 16ga?Kinda not thinking so. But if as in the pic I have shown of the multi core transformer, if the outer windings are primary and the middle winding is secondary, it may be more like the speaker analogy, of which I know works out to a gain by adding more drivers at same power in for each case, where we are using more drivers into 1 medium, either the open air for the speakers or a single secondary for the transformer. Ill upload a pdf on the subject that I have put up many times before that may make some sense of what Im getting at.
Can you show what you have done and how you are doing it? Pics?

here is the pdf on multicore transformer 'power amplification'.

And Im including one on classical flux analysis that I think should coincide with the first pdf.

This is from page 9 of the pdf which I based my 5 core design on.

Looks like loose-coupling maybe this is the secret. Cores can receive  radio waves.
