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.

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.

Hi void,
I came across this video yesterday which maybe of interest to many.
High voltage disturbing  2-coils transformerhttp://www.youtube.com/watch?v=fURFkTC1rmQ

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.
 

Hi magpwr. Not sure what to make of that video. If you are putting enough power
into the primary, I guess you should be able to light the light bulb even if the secondary
only has one turn. I have watched a number of this guy's videos. He has another video
called "Free Energy generator is not possible." that is similar to the video you linked
All the best...

Hi NickZ. It appears Akula may possibly have already sold the rights to some of his devices, or received some investment money,
or because he is actively marketing these devices he is no longer publicly showing new info on them. If he did already sell the
rights to some of his devices, then Akula would likely not be able to show any more information about those particular devices, at least
not publicly anyway. If you see some of Akula's recent videos, he is showing what looks like new oscilloscopes and spectrum analyzers, etc.,
as well as what looks like possibly a bunch of brand new bench tools like a lathe and drill press and miter saw, etc. It appears Akula has possibly made
some money from one or more of his devices already, either from just an initial investment to support his further research, or possibly from a
sale of a device.  We all saw Akula's electronic test equipment in his earlier videos which was quite basic stuff. Now he is showing a whole lot
more fancy and expensive equipment .

All the best...

it seems doubtful that the business people in Germany or other potential investors would not have caught on to any tricks pretty quickly.
The first thing any reasonable person is going to do is arrange to have a device fully tested/examined in their own lab under their own conditions.
All the best...
