Bifilar pancake coil overunity experiment

[ayeaye]

The connection in the Tesla's patent provides the maximum difference of potential between the windings, that is 1/2 of the voltage on the coil, which enables maximum charge between the windings. And there should have been a reason why this was necessary.

Now some may ask why did i create this thread. I found a way to calculate input and output power of a coil with Python. Then i did an experiment with a bifiar pancake coil made of some sort of shielded speaker cable. The calculations showed overunity, that is when i created this thread. But then, the more precise i went with the calculations, the less overunity there were. Though the overunity did not completely go away. By repeating the experiment i never got the same results again, and there were never overunity. So i cannot be sure whether that one time there was overunity, or was it about some imprecision of measurement. Without being able to replicate it exactly the same, i cannot be sure what was the case. That's all i can say, i don't want to cheat anyhow.

I have a kind of poor equipment. Only an old analog oscilloscope, only Arduino to generate signal, and i have to make some DAC with it to even create sine, with any higher frequency, otherwise i cannot even find resonance. All i have is a pulse.

This here, is really everyone doing important work. Finding no overunity is as important as finding overunity. Like if it will be found that some type of coil never has overunity, that's important, that's much less remaining to find out. Do any coils even have overunity, what would be left then is cold fusion, big Tesla coils, resonance, things like that. Overall, the work of everyone here, doing important contributions, should be rewarded. Not only these who once may find overunity. Because when they once do, that's also because of the work of many others, whose work finally enabled to get the result. I know here are serious people who do everything they can to research overunity, i love you guys, you do good work, that needs to be done, not done wrongly at all.

And yes i understand, with an unknown thing one wants to get as much information about it as one can get. F6FLT did a good job in that, i appreciate, there is nothing negative i want to say. And yes i know how difficult it is.

The reason is that it maximizes capacity.
As you said, in the Tesla's patent there is a voltage U/2 between two consecutive turns while there is only U/n in a normal coil, n being the number of turns.

In any case, it's just an LC circuit but with a much bigger capacity with the Tesla's winding.
Tesla used it because particularly at his time (but also today less or more) high voltage capacitors were difficult to make.

Hi F6FLT,

Okay, fine on your reply #189 above.

Would like to draw your (and ayeaye) attention to some patent applications in which "capacitive" windings are involved but not only with distributed capacitance but with normal capacitors connected between the two start and two end wires of the windings, see here an application for the latter, for instance:

https://worldwide.espacenet.com/publicationDetails/biblio?CC=WO&NR=2010003394A2&KC=A2&FT=D# 

It is like your circuit on the left hand side in your post #179 but in the patent application the Cs capacitors are not shown, only the Cp ones, i.e. they are lumped element capacitors. The inventor refers to applications in which capacitive i.e. reactive current is utilized, he says magnetic field from such current can also do work in the same way as real current, and to the outside circuit such coil assembly shows capacitive behaviour at the low frequencies and power factor is (quasi) zero.
The German text of the application can be on-line translated freely if you click on the Description icon in the left hand side vertical Menu and then choose your preferred language in the small window in the middle.
The same inventor shows an application for induction heating with such coils, see this link which also translates German text to English:   https://patents.google.com/patent/DE202014001838U1/en

Here is the original German text in which the math formulas can be seen better:

Of course, in this link you can also have English text if you click on the Description icon.

My humble opinion to readers here is that only correct measurements can decide whether such capacitive coils with near zero power factor have any advantage in a practical application like say inductive heating or in electric motors etc.
