My thought : schematic is correct but not all elements are detailed shown  ;D

Just a  reminder that Patrick Kelly who posted in his extensive Energy book showing the Electrodyne OU Tesla Switch arrangement that he initially had the diodes posted in a way that looked correct (after being told they were backwards) only to find out later that the apparent backwards orientation WAS correct all along.  He has since corrected them so they now look backwards but this is the way it worked (and worked very well).  So if someone has diodes that look backwards I don't automatically assume they are wrong.  It's probably worth trying both ways if possible.

That was my feeling also, but it was said in a previous post that some diodes were incorrect and when corrected it worked.

Thought I would clarify a bit why I got so excited with this EMP stuff.

What was the party trick of Ismael Aviso?
   Shooting stuff up in the air.
How you do shoot stuff up in the air?
   EMP pulse.
How to make one from tiny average input?
   Capacitor discharge OR flux compression generator!

Also if one really wants to negotiate with strong neoydmiums on equal terms
there is need for another strong neodymium OR EMP pulse.

And the fact that I "discovered" with my pulse motor is that when you
drive it with mini-EMPs and very low resistance coils then for
short period of time one can treat ordinary wire as superconductor.
Meaning you get your EMP and also almost all of the energy is left,
because it will not dissipate in resistance like in classical approach.
And you can do with it all you want.

Also I would point out the Time Constant graph...
http://www.tpub.com/content/neets/14191/img/14191_30_2.jpg
0.7TC point looks nice cut-off point for drive coil, doesnt it? :)

Could you please explain somemore details of the setup. Is there a basic arrangement which one can use do understand the effect ? Is the flux compression achieved by shorting a magnetized coil step by step over the coil distance and so forcing the magnetic flux to create a bEMF in a "shorter coil" and lower inductance?

Indeed very intresting. Please keep this up.

Thank you

He has removed all links to the old site but I have a copy of every picture he had ever posted.
In the picture below I am trying to find the lenght of his coil knowing that is a bit shorter than 2 US power sockets.Can anyone tell me what are the dimension of those type of sockets? Those sokets where taken from the same picture.

Nice guys,

I am keeping a close eye on this setup. I'd like to give this one a try. Seems like it has alot of promise, is there anyway we can get by without using microprocessors? I'll see if I can come up with anything!

The space of the "Plug"[two power prongs] is Half inch on center.
You can scale from there.

Stefan doesn't have the old thread saved somewhere?

I threw a grid on it and I'm going to say the coil length is from 1.5" to about 1.6" or 1 and 5/8".  I couldn't get much closer because it's pretty blurry when I blew it up to put a grid on it.  If you by chance have a higher resolution or larger view of it we might get closer.  But I'm guessing you can do that anyway now that you know the spacing in American outlets is 1/2" center to center for the plug.

Hi, thanks for interest :)
First I want to say that I dont think that there is "free energy" in FCG itself. FCG is just a tool.
Second I do not yet have FCG because in small setup you do not really need one. The picture changes when you scale up.

Let's say you need xA 10V impulses.
Capacitors?
Very unefficent. You would need yF @ 10V.
Storage formula is 1/2CV^2 means that you will need
them big and bulky. Instead of that (y/100)F @ 100V
would store same energy.
But now it is stored @ 100V. How to get it back to 10V?
In form of very sharp impulses?
Ordinary transformer is out of the question. It will also
get bulky (and slow!) as hell. Flyback is better but not quite there.
There would be serious overheating problems.

Which is exactly what Ismael Aviso has, BTW... !!!

So you need impulse transformer that has extreme power handling
capability w/o overheating, small mass, very small resistance and
very small inductance.
Essentially an FCG that would not explode :P

There may be solutions and I'm currently doing a research on it.

***

Now what you do need this FCG for in first place? In nature it is impulse what gets job done.
I will post scope shots of my impulse motor drive module today/tomorrow, that should explain it.

Hi Romero,

Earlier you asked what the reason was Richard paralleled so many diodes.

Is it possible he also paralleled the diode bridges? I think so.
Normally a high voltage high amperage diode bridge has pretty high forward voltage drop, at least in the order of 1V, 1.2V or even higher per diode.

This could be an explanation. The side effect of paralleling is the amperage for the diode bridges also increases.

Ok, did what I could with my scorched reeds...
This post is about DRIVE coil and superiority of impulse tech.
But of course some of the points apply to generator coil also.

***

counter_emf.png

This picture illustrates the CounterEMF of drive coil at optimal rpm.

***

coil_1.png

Here you see medium efficency setup. Some thing are good some things bad.

The on/off flicking in the beginng is not intentional and is result of scorched reed (bad).

Coil: Thin wire (bad / good because can handle RF), Tesla bifilar (good), steel bolt core (bad).
That makes 11.7ohms and 15.55mH.

EMF - CEMF is ~12.5V making ~80% goes to moving rotor (good).

Analyzing top of the input wave appears that coil is charged during 3...4 Time Constants (bad).

Comparing area of Input EMF vs Recycled EMF we see that some part gets recycled and helps to move rotor but ratio is not too good.

***

coil_2.png

Here you see high efficency setup.

The on/off flicking in the beginng is not intentional and is result of scorched reed (bad).

Coil: Thick wire (good / bad because its solid wire and cannot handle RF), Tesla bifilar (good), RF ferrite core (good).
That makes 1.7ohms and 7.55mH.

EMF - CEMF is ~12V making ~75% goes to moving rotor (good).

Analyzing top of the input wave appears that coil is charged during less than 1 Time Constants (good).

Comparing area of Input EMF vs Recycled EMF we see that very large part gets recycled and helps to move rotor.

***

Now the reasons behind good/bad division one can find out just by investigating Time Constant chart and sources of losses in electrical motors.

I dont think that path to COP > 1 & COP < 4 machines lies in some magic tricks. It is about understanding the sources of losses and systematically eliminating them. But I do agree that eliminating some losses may prove to be tricky :)

Good luck!

@yssuraxu_697
Great results, thanks for taking the time to post them.  I will read them carefully as there is alot of info there!


@all

Okay guys, spent around $100 rubles on parts yesterday at Radio Shack etc for various energy experiments.  Lol payday.   Anyway

FEYNMAN HAS SMALL PROBLEM WITH 555 TIMER / MOSFET!

I would appreciate some suggestions...

I build a 555 timer PWM circuit , based on schematics for HHO generation.  The Mark-space Ratio / Frequency Kinda work despite being a little finicky, and with my 0.01uF cap I'm getting 2khz - 80khz adjustable spacing. 

The problem is that from what I can tell, the IRF510A MOSFET is inverting the pulses.

I run the pin 3 output of the 555 into the gate of the IRF510A MOSFET through a 100ohm resistor, then I drop another 1k ohm resistor from the MOSFET gate down to (-) GND.  See attached schematic  (I substituted 100ohm and 1kohm resistors for the 220ohm / 820ohm resistors on the diagram).

The MOSFET drain is connected through a 1kV HV diode to the (+) 9V.  In parallel, I've connected a dummy load which represents my 'coil' which I'm going to drive (this is actually a ferrite electromagnet, but I digress).  The resistance of the 'dummy load' from mosfet drain to (+) 9V is anywhere from 100ohm to 1k ohm. I tested both.  At 100ohm,  the dummy load pulls 75mA.  At 1k ohm, dummy load pulls 7.5mA.

Lastly, the MOSFET source is just connected down to (-) GND.

The problem I'm getting is that the output of pin 3 is completely inverted from the output as measured at the MOSFET drain.

For example, if my input is PWM with 1% duty cycle and a specific frequency, on the drain of the MOSFET I see a 99% duty cycle wave at the same frequency.

I plan on snagging MOSFET drivers in the future, and I know I could invert the logic with a transistor, but I want to know if I'm doing this properly and to hear other people's thoughs.  Thanks.

-Feynman

P.S.  The point of this is to run HV PWM , waves of say 1% duty cycle and high potential, probably at least 60V - 300V into the electromagnet.  Then from there I plan on basically doing some magnacoaster-style experiments , and some coil shorting experiments in the presence of a biasing magnet.

Thanks again
