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.

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...
