Read Tesla's patent again.

He doesn't say that the electrical potential generated is 250,000 times greater in the BFC, he says the energy stored is 250,000 times greater than that stored in a SWC, (assuming a 50V potential between adjacent windings in the BFC). Big difference.

Was a quote from syncro, I didnt notice the issue at the time. Thanks for the correction

MH says there is nothing more to try. Nothing. ER says there is.  MH puts together examples using false data, where the outcome always leans even more in his favor . Er has not provided falsities that anyone can point out so far. I have found the ER will let you know if you are going in the right direction, just that you have to ask the right questions. Im ok with that. If it all turns out bunk then you can say otherwise. Mh will daily press that there are no more directions to go. Like is that warming on you here?? You removed ERs post, but mh gets to run nelson off and just puke on every new thought that arrives. Let me ask you. Just because ER does not tell you much and considering what you have seen of his vids, would you absolutely agree with MH that he does not know how a coil works??? if so, you are scaring me now. Is the world flat? Does the earth rotate around the sun?? If not, got proof?  Well back when these discoveries, earth ball, sun is the center of solar system, there were those that argued it based on the tight box surrounding them, not an open mind to new possibilities

Not here to discuss the coil, just here to defend myself.

-  I never said there is "nothing to try" or "no more directions to go" - don't put words in my mouth.

-  I did not do an example using "false data," I used exemplary data, and there is a huge difference.  What the hell does "my favour" mean?  If you put the correct data for Conrad's coil resistance into the analysis, the amount of stored energy in the self-resonance of the coil is still minuscule relative to the continuous power burn to sustain the self-resonance.  Is this fact not sinking into your head?

-  Why don't you make your own pancake coil and with the proper resistance value do the analysis yourself?  Guess what you are going to find?  You are going to find that the results are about the same:  huge continuous power burn relative to the stored energy.  Aren't you curious about this, you are on a forum discussing energy?

-  I did NOT "run Nelson off," don't give me more of your crap.  I told Nelson the truth when I was discussing various technical issues with him.  Is speaking the truth not acceptable to you?  Don't tell me the technical level on this forum is so low that you still get excited on seeing a bloody light bulb being lit after 7+ years.

-  "Puke on every new thought?"  Only in your unhealthily obsessed mind.  This has to stop.

-  Re:  Understand how a coil works?  Golly gee, you actually do have to understand how a coil works.  Some dude named "BeSharper" wants to join a garage band and play the guitar.  Do you think he can just show up and mangle his fingers on the fret board and strum with a pick without even knowing what a chord is or what a musical key is or what a 4:4 beat is?  The other dudes in the garage band will kick BeSharper's ass out the door in no time.  It's called life.  BeSharper can cry out, "But I am an undiscovered musical genius and I don't have to understand music!" until he is blue in the face or he can roll up his shirtsleeves and learn about music and how to play music (or he can do nothing and sing backup vocals for Yoko Ono instead).  Is this R E S O N A T I N G with you?

You stop bad-mouthing me and go work with your coils.  Your sick obsession about me has to stop or go see a psychiatrist.

Back to talking about pancake coils.  Hopefully most of you understand how a coil actually works on a thread discussing the inner workings of coils.

Ok-let's cut through the BS,and carry out some side by side test's between a BPC,and a single wound coil-of the same physical size,same size wire,and same length of wire.

My first test was to take a close look at a quick pulse sent through each coil.
I have a diode on one of the input leads to each coil,so as we get a DC pulse going into the coils only.
I am running at a frequency of 20KHz,and this allows the coils to ring down to a stop before the coil is hit with the next pulse.
Duty cycle is a mere 1%--so a very quick pulse.

I read in one of the replies here,that the BPC has no inductive kickback.
Well,we just found that to be incorrect with this simple test.

Looking at the two scope shot's below,we can clearly see the inductive kickback spike,followed by a small forward spike of larger amplitude,but shorter duration-the beginning of the ringdown of each coil.
We also see(as i stated before)that the BPC has i lower resonant frequency.
But as we look at the induced voltage,and the inductive kickback,we see there is no difference between the two coils.

We can see from the scope shot's,that both coils were subject to an identical input pulse,at the same frequency,where the voltage across both coils reached 8.5v during the on time.
We can see that the inductive kickback from both coils is also exactly the same.

So,we have eliminated one myth associated with the BPC-that being that the BPC has no inductive kickback,when in fact it is identical to the single wound coil.

Next test is the electromagnetic field strength of each coil,for a given P/in.

Ok,the second test is to see which of the two coils is better at inducing a secondary coil.
So a P/in for P/out test.

The secondary coil is the secondary from a MOT,where i am using 1 half of the windings-->coil is split into two sets of windings--from other projects.
The MOT has a 680 ohm resistor across it as a load.

First,with a set V/RMS of 1.6v across the BPC,the frequency was raised until maximum V amplitude was achieved across the 680 ohm resistor on the secondary coil(the MOT coil),by doing a sweep from 500HTz to 2MHz.
Once maximum output frequency was found,we then placed the scope across the 2.2 ohm CVR on the BPC,and the second channel to read the voltage across the coils-so as we could calculate P/in.

The very same test was done for the single wound coil.

So here are the results.

BPC

P/in=1.6v @ 216mV/RMS over the 2.2 ohm CVR
P/in= 157.088mW
Power dissipated by CVR=21.207mW

P/out=1.56VRMS over 680 ohms
P/out=3.578mW


Single wound coil

P/in=1.6VRMS @ 208mV across the 2.2 ohm CVR
P/in= 151.264mW
Power dissipated by CVR=19.66mW

P/out=1.68VRMS over 680 ohms
P/out= 4.150mW

So,from this test,it would seem that the single wound coil out-performs the BPC in electromagnetic induction-or energy transfer to another coil.
