In the 3th part of his video, Stela shows a ferrite transformer working without any magnetic field and powering a bulb  as load.
Can anybody explain how to do that ?
Sorry but it's pretty unusual for me !!

Technically, toroid transformers are something I do not fully understand.  How they can work, if by theory almost all magnetic field is inside of the core. How the magnetic field can cut the secondary coil on the other side?

Hi John.K1. Magnetic flux is concentrated primarily within the ferrite core and
moves through the entire ferrite core to the secondary, where the flux induces
current in the secondary windings.
All the best...

Hi all. One interpretation of Kapadnadze's earlier devices is that applying high voltage pulsing through a sparkgap to
a coil wound on a ferrite core causes some process to happen inside the ferrite which releases excess energy into the
system, which can then be used to power a load.

The following short video shows some preliminary tests I am doing to put this concept to the test. The video shows that
arcing increases the input current draw to the flyback driver circuit, as well as tests whether placing a ferrite yoke core
directly in a sparkgap arc causes any noticeable excess power to be available to a load. I did not notice any excess power
in this preliminary and very rough test. I plan to test more extensively over the next while to see if I can see any excess energy
when pulsing ferrite in this way. The specific type of ferrite used may make a big difference however, for all I know, as there are
many different ferrite mixtures out there. If anyone has a suggestion on a specific type of ferrite to use, I'd be interested to hear
about it. Both Acca, who posts here sometimes, and Stela have shown a similar sort of test in their videos, so I thought I'd try a
similar sort of test while monitoring the input current to the flyback driver, so you can get an idea of what is happening with the input
power while conducting the tests. The orange multimeter in the top right hand corner of the video screen is showing the input
current to the flyback driver.

Here's the comments from the video:
Flyback driver:
Supply voltage: 24 VDC
Input idle current: ~0.6A
Load: 24W, 12V halogen bulb   (P.S. Actually I think the halogen bulb is 35W, but the writing is worn off it now... )

Conducted two basic tests:
Part 1 - Test to see if sparkgap arc distance affects the current draw on the flyback driver.
Demonstrates that with a wide sparkgap the input current increases to roughly 0.7 A to 0.9 A or so. The input current draw to the flyback driver
increases more and more as I make the sparkgap distance shorter and shorter. With a very short sparkgap distance the arc is more concentrated
and intense, which causes more current to flow through the sparkgap, and the 24W (actually 35W) halogen bulb starts to light. The input current draw increases
to about 1.3 A with a very narrow sparkgap distance, while the halogen bulb is lighting. The halogen bulb is not lighting very brightly however.

Part 2 - Test to see if placing a ferrite core directly in the sparkgap arc can provide any extra power to a load. This is based on the concept that
stimulating a ferrite core with high voltage, high frequency pulses can cause the ferrite core to emit extra energy into the system due to the
HV (high stress) pulsing of the ferrite magnetic domains. I placed a ferrite yoke core-half in the direct path of the sparkgap arc to see if I could get
any more power delivered to the load. The arc was hitting the edge of the ferrite core and bending around it. With the sparkgap distance set short,
the halogen light bulb lighted, but it was not noticeably any brighter than without the ferrite core in the arc path. Input current draw to the flyback
driver was also around 1.3 A or a bit higher when the halogen bulb was lighting the brightest, but no increased power to the load was noticed.

Maybe higher voltage is needed, or a different type of waveform, or a specific frequency, or maybe only certain specific types of ferrite mixtures work.
Another option is to try a different type of arc. I was using a HV rectifier to charge a 0.001 uF capacitor, and so the sparkgap was discharging in large HV
pulses. A test could also be tried without the diode and capacitor to produce a different type of a more 'white noise' type of arcing in the sparkgap. I may
try this next to see if there is any difference when placing the ferrite in this different type of sparkgap arc.

Hi Void.  I know that magnetic field is almost all in the core- how much there are  losses depends on the core permeability. But the induction can take a place when the magnetic flux cross section the wire- which is not the case, because all flux travels in the core. So how is possible the induction takes a place?   The mistery

Hi John.k1. I watched through that whole video, and I did not see anything much
out of the ordinary. Not all the flux will be contained in the ferrite core for one, and also
if you are pulsing with high voltage there is a strong electric field around the coils as well,
and energy can couple from coil to coil through this strong electric field. Keep in mind
that in the Ruslan/Akula device which we have been testing with, that energy from the tesla coil
is coupling to the 'inductor' coil primarily through the electric field. I confirmed this by replacing the
'antenna' with a cylinder of aluminum foil and got about the same amount of energy coupling to the
grenade coil. High voltage AC to a coil will generate a strong electric field around the coil.
All the best...

@Void:
That yellow color around/in an arc often means that your arc is energetic enough to be "burning" the air gases themselves. Creating oxides of nitrogen, which then create nitric acid when in contact with water or water vapor. You can try making the arc inside a small glass container, like an inverted shotglass, and if the air in there becomes yellowish over time, that's what is happening. Needless to say you don't want to be breathing much of this stuff, but the tiny amount from your arc isn't going to be harmful.

The yellow color can also be a result of cadmium plating on the electrodes burning, this cadmium vapor is also dangerous to breathe. Sodium is another substance that makes yellow tints in flames and arcs, like if the electrodes are contaminated with salt. I don't remember what zinc plating does at the moment.

As to photography, that will depend on a lot of variables. It helps if you have a good camera that can be completely manually controlled. You need to play with f-stop, shutter speed, ISO number, white balance until you find a pleasing result. I get the best results with flash and autofocus off, manual white balance and low ISO numbers for good color saturation.

Bonne continuation...

I yesterday speak with Ruslan and Ruslan everything explain how need made divice on 1 kW.
Need generator like this https://www.youtube.com/watch?v=TtjlIkgLJ7M who making 4-5 pulses, then pause, then again 4-5 pulses with frenquency push pull (27 kiloherc on Ruslan divice). Resonant capasitor 0,47 uF. Inducor 10 meters. Output coil 40 meters. Tesla coil can be 20 meters for 0.7 wire and 40 meters for 0.5 wire. Inductor on Tesla coil have 6 turns, wound turn to turn, with about 1 cm gap betwenn primary and secondary. On plus Tesla coil inductor go 24 volts. All system 24 volts.
First need wound of aliuminum plate on tube one turn not shorted. Then wound output coil, but always wound in same direction now. It have 6 layers, but now always need wound in same direction. Then inductor begin from same direction wound like multilayer coil, then gose to end, go back and wound again, in other words Tesla bifilar coil inductor is. Aluminum one turn go to ground. Multilayer coil first layer go to ground. Indutcot throught resistor go to graund, but if no automatic resonance ajustion, then resistor is not nessary, it needed to not burn generators, then signal gose from ferite ring secondary mounted on 3 turns resonans windings. On output multilayer coil is 0.22 uF capasitor and from it gose to hight speed 4 diodes and then on output is DC curent (can be capasitor 10 uF after diodes) and that gose to load and 220 to 24 volts power supply.
 

  Wow! Thanks MenofFather.  Many changes to the way we had made the grenade previously.  I never believed that all those inverted polarity turns made ANY difference, and this new all one direction windings of the grenade coils (6), confirms this.

  Hopefully you can continue to be able to contact Ruslan in the future, for more "details".

Ruslan say something that, that inverted polarity turns is better. Its seems give higher voltage on output. I not know then oher time I again speek with Ruslan. That be looky moment.[/size]
 

hi MenofFather,

It seems Ruslan gave false information from the begining related to tesla coil frequency 1.5...1.7Mhz.

After creating a circuit which perfectly sync tesla coil detected frequency and divide by 60 or 50 and produce signal for my prototype PWM circuit with dual channel output 20% to 45% duty.
The only thing achieved was a flickering bulb at a certain frequency also similar to what hoppy have achieved as well using manual pwm tuning approach.

The approach which i now believe may work is using the high voltage in kv pulsing approach either via tesla coil or dally's nanosecond pulse approach using coaxial cable with shorted end.

Take note at 30volts power supply i merely got 1.3kv nanosecond pulse from tesla coil antenna(Short telsa coil ~7cm 20AWG.Maybe i should not have shorten tesla coil).
But what if coil was powered by 150volts or 5 times more input voltage.Maybe 1.3kv pulse would become 1.3kv x 5 =6.5kv  if we are lucky.

*********High voltage probe is needed for scope****************

I think dally approach is better if we are using ideal component for pulsing at high frequency.My nanosecond generator is able to provide repetition pulse at 50khz easily using recently posted attachment.Now i have design pcb using RF mosfet and RF mosfet driver $$ which runs at 50Mhz max which is overkill for this application.

The reason why i say dally approach is better is because Antenna with huge gap to multilayer  coil is not needed.This gap itself creates a lost.

The coaxial cable can be wound directly over the 48 turns bifilar layer .

But Dally old pulse generation circuit should not be used.
