The bifilar pancake coil at its resonant frequency

[Jeg]

The problem with your statement is you are not saying what is so special about displacement currents.  What advantage or application does this geometry give you that supports displacement currents between the wires of the coil that might store a few microjoules of energy?

Their specialty is described very well by the inventor. They make a so intense electric field between adjacent turns that solenoids cannot reach. Pancake geometry helps in that displacement current moves perpendicular to the flux movement, like what happens between two normal plates of metal forming a cap. Many applications depending on what you want to do. An interesting application would be to use it for a controlled spark gap. Like here back in 2014

This is an appeal to ridicule, I didn't say it. The patoskeptics are just leading this forum in number of posts per person.

You have no idea what you are talking about. I have a lot of posts for several reasons. Number one is that I have been a member of this forum for many years. Number two is that I engaged the notorious Rosemary Ainslie over several threads that went on for years until she was very definitively proved to be wrong and indeed to have falsified data in a long series of streamed video experimentation by her own team and led by Poynt99 and the late MarkE. Number three is because I've helped many people, just as Cifta has done, to get their various projects working, notably Joule Thiefs and Bedini motors, and along with MileHigh we developed and discussed the "better than Bedini" MHOP. What have you done? Nothing, that's what, mister Newbie. I'm proud of my post count. Yes, I point out errors when I see them, and your posts are full of errors, which you won't acknowledge even when you are soundly proven wrong. As we have demonstrated over the last couple of days.

Prove it - most of results in this lists are positive, instead. BTW The yield of complex microprocessors is bellow 50% - should this serve an evidence, that these processors don't exist, according to you?

Do you know what a "straw man argument" is? Look it up. It is a wellknown logical fallacy used by people who have no rational argument. Your mention of the yield of microprocessors is a STRAW MAN and is irrelevant to the FACT that your wiki list simply does not include many failed EMdrive experiments. Did YOU write that wiki article?

Because of disruptive agenda of trolls like TinselKoala or MileHigh. The guys who were sucessfull with overunity don't visit this forum because of them.

Here you are referring to the comment about UFOPolitics and his "Asymmetric Electrodynamic Machine". Again, your claim here is not true at all. Go and read that enormous thread at EF. Here's a link to his claim of OVERUNITY GALORE:

Note the date. Note that there are in fact _very few_ disbelievers posting, and neither I nor MH have ever posted there. Much later the believers start to discover that there is no "overunity galore" and in fact no overunity at all, but just a bunch of failed NTE mosfets, badly produced motor parts and burned out components. Along with a bunch of nicely done graphics of motors that in the end do not produce a single extra Joule of energy and are in fact quite INEFFICIENT.

And there are no "guys who were successful with overunity" posting here or there. There are many claimants, and there are some tantalizing preliminary results from genuine and honest researchers like Partzman, but they are all still buying their electricity from the grid, just like you, and no one has credibly demonstrated any self runner or daisychained device. If you think they have... what are YOU doing here then?

You have earned yourself another ROFL.

Speaking your language empowers you....  Me no speak " (your brand of) technical aspects...." STARVE!

Right, and here is the ambrosia that has been eluding you all this time as well as for 95% of the amateur experimenters that play with coils for years:

A coil integrates on voltage with respect to time to yield a current flow through the coil.  The amount of current flow is also inversely proportional to the inductance of the coil.  A coil differentiates on the current flowing through the coil with respect to time to yield an opposing voltage to the change in current flow.  The amount of voltage is also proportional to the inductance of the coil.

There is your food, yet you no speak that.  Without undertaking to try to understand those four sentences you continue to starve.

As TK said in the modern era we use capacitors.  Think about this:  You are fascinated by the fact that a bifilar pancake coil can store energy between the adjacent turns of the coil.  Say that there is 50 volts between turns and there are 10 turns.  Well, you can put a 500-volt capacitor across an entire conventional solenoid coil and get the same results.

To put it another way, you can replace a bifilar pancake coil with a regular solenoid coil in parallel or in series with a very small high-voltage capacitor.

Yes, there may be some spark-gap applications for bifilar pancake coils like you are discussing.  That is perfectly valid.  But those are more mechanical issues than electrical issues.   Let's play a "black box" game.  Suppose you put a bifilar pancake coil inside a black box and the only thing you see are the two terminals for the coil on the outside of the black box.  When you test those terminals you will say that you observed that there was a property of inductance telling you that there was an inductor inside the box.  You also were able to observe a self-resonant frequency for the coil indicating that it possessed some inherent capacitance.  That is all fine and good.  However, on a fundamental level, all that you really observed was that there was an imperfect real-world coil inside the black box.  The fact that it was a bifilar pancake coil made no difference to you.  In that sense there is nothing special about a bifilar pancake coil.

I have absolutely no interest in your memorized perspective.  You would be as smart as the folk you plagiarize, if only you could pick up where they left off.....  No....all anyone gets from you is a fucking playback.....  I can read.....  What you claim to know, anyone can know.  What you try to drill into the heads of those you consider less than yourself, can be found in countless books, and web pages.  I don't want nor need a lesson from you, the net is a much better instructor, can't say I miss the god complex when doing a google search........

ambrosia....give me a fucking break..... more like Grape nuts..... thats right, I equate what you give to a box of (stale) dry shit.....

You are oblivious regarding what I know, but you have my permission to continue thinking you aren't....

It's not about memorizing the knowledge or reciting it like a book playback.  It's about understanding it and applying it, and that includes in real life on your bench.  Don't play strawman on me please.  Relative to what goes on around here, understanding how a mysterious coil works is ambrosia.

If you want to be the anti or alternative knowledge rebel, that's your prerogative.  But when someone is discussing their circuit often it really is a nuts and bolts kind of thing and not an exploration into semantics and intangibles
