I do not know why the pictures got so huge! At least, they are shown enormous on my scree. The resolution, perhaps?

Bajac,
That's huge... . My poor little work space the kitchen table is jealous... I will be moving my stuff eventually. As soon as " the warden " ( my wife ) gets fed up with my working on it...
You know I have to ask the question ( yeah yeah I know you have limited time )did you abandon the Fiquera transformers that you originally made or are you doing something as a add on...basically are you experimenting on something to come back to the original design...the only reason I stopped working towards Tesla's stuff is... as I was emailing Patrick I told Him Tesla's wireless had limited distance and He pointed me towards the Figuera and I started from scratch...and I will stay on it until something " doesn't work " then I will move on...
And thank you for the kind words...

All the Best

PS I take the picture on my apple iPhone and then email it to myself... when I hit send it asks what size and I always enter small... so I don't go into gigantic space

wait wait wait... Hey I spotted the breadboards right next to the black and decker box...you can't put those things on like that it will never work. You're wasting precious time using breadboards in that fashion...the millivolt will never accept a milliamp and run a 2n3055 or BDX53c ...did I ever tell about the time I was in industrial Education class and put cigarette foil into the 120 volt socket both sides...we had do detention for a whole week for that stunt................

"Perhaps...."
Yes, that's right, YOU posted them at full resolution of 1935.96 kB, 3264x2448 pixels.

YOU can, for a brief time, go back and remove them from your posts, and use your favorite graphics application to shrink them down to a _maximum_ of 1024 pixels wide, or even better 800 pixels wide, and repost them. Then people won't have to scroll back and forth trying to read comments like yours... and this one.

Better hurry though because YOU can only edit your posts for a limited time. After that, we are stuck with your supersized pictures and hard-to-read posts, unless Stefan edits them for you or we roll over to a new page on the thread.

How do I send request Stefan? Those large size photos are annoying. I apologize for the mistake!

I have not abandoned Figuera's devices. I am doing parallel research on several of them. But, it is my opinion that Cook's apparatus is the simplest device to test the concept used by other inventors such as Figuera.

The board you see on the photo is the driver for the Figuera's device.  I am using an Arduino controller and two PN2222 transistors to drive the IGBTs. But I will modify it to use only one PN2222 and invert the logic of the program.

Hi all,
I did some simulations on Figuera drive circuit like proposed by Patrick. I feel it is good to have a visual representation of behavior.
Circuit feed = 24V
Resistors = 100R
Step = 1 ms
Inductors = 1mH

!!! Hint regarding simulations: They can show up KNOWN facts only and help to understand  facts that are too complex to grasp them by looking at a schematic. Let's look at it like a kind of prosthesis for our brain. It will never deal with unknown science. That is the privilege of real experiments only. But simulations may help to get a more rugged setup with less invisible uncertainties.
So please do not ask anybody to simulate the magic of Figueras device before we have a formula.

I did another simulations where I modeled the flux by electric current, the ampere-turns by driving voltage and the permeability by resistors (see diagram with black background). This is an accepted way to do rough simulations in magnetics.
I did the simulation with triangle shaped drive in order to see the basic behavior. If operated with sine shape with offset (still no flux reverse) the result at center coil exercises a sine signal as well.
It seems that all air gaps are essential in order to provide for feedback another flux shape than for driving (but just a feeling).
An of course I cannot simulate the Lenz feed back behavior.

Wow! Only one pic per post accepted !?!?!?

  I mentioned the hour glass shape of the cores a while ago. Think in terms of fluid dynamics.The choke point would have to produce a greater passage speed or a compression of the field inside the winding. I was always under the impression a magnetic field is not compressible. Excluding distortions, a core can only hold so much and that's it. It start to turn to heat in the same way an induction heater works. The only exception I was able to find is when coils are wound with a subtractive cancellation winding like used in some mag amps. Feed back can ether add to or subtract from. Sometimes its called biasing but it all boils down to a conserving application of the output against the input. Even in a dynamic microphone using electrets as the static field. If there is no polarization in the form of a field you have to use some energy from some where to produce one in order to have a reaction.Even a iron core has a  state of being regardless of it being polarized or not. The wire not so much without a charge moving. I have never found a permanent copper "magnet" wire in the past.
 The focus continues to be on everything except how to make it self run. It's the only thing which makes it different from any other common device. How did Church Hill put it? The right thing in the end after every other possible wrong thing is exhausted. So be it.
