Kapanadze Cousin - DALLY FREE ENERGY

   GeoFusion:
   Thanks for your comments.
   I'm still working on my set up, trying to tune for the best harmonic peeks.  Not easy... But, I'm seeing some interesting effect. There are several harmonics, but I'm not able to tune to the best one, yet. Seams like I need more voltage to kick the system into the higher resonant peeks.  Maybe some better tuning caps might also help.  Anyways, I'm still at it... 
   Good luck with your system. Waiting for your pics and videos.

  Geo, remember that Akula's first device diagram is NOT complete, as it doesn't show the yoke's secondary coil (25 turns, or so), or how to connect that coil to the 310v rectified output from the inverter, or where the other end of that secondary coil is connected to. Looks like the yoke's secondary coil is given a 310v DC pulse from the inverter.
  Kapanadze also used 220v input (from his inverter) to run his circuit. 

   I'm still only inputting 12 volts, until I can fix the fet overheating issue. Three chokes on the input doesn't keep the fets running cool, when the load is 300 watts or higher.
 
  Anyways, let us know how it goes with you.

Hi Guys,  Can somebody tell me why is Ruslan using some 25m (or so) long ground cable?  Wouldn't be more practical to have much shorter length?
Cheers,

  John:
  The ground cable for the Akula second video device was supposed to be about 37.5 meters long, according to Akula and Ruslan, and, is also the same length as the grenade's output coil with 168 turns.
And the Kacher's HV secondary coil is also wound to about 1/2 of that length, 18.75 meters.

   Ruslan started with a short ground connection to his house radiator, which was about 5 yards away. But, you'll notice that on his newer videos he shows the longer 37.5 meter (or so) ground cable.
  The ground cable in this case, is also a type of antenna, tuned to a certain frequency, and which also becomes part of the whole  tuned circuit.  Or at least, that's the theory, as I understand it.

Hi Nick, Thank you for your answer. I just wanted to open the discussion about this "detail"  which might play important role here too. 
Take a look at the experiment with grounding- performed by A. Romanov  : https://www.youtube.com/watch?v=PI1dSZ_dxRM

The aim of the experiment:  We have two coils of different inductance and we want to see where is going the resonant frequency when using ground cable.

Experiment with the 1st coil:   One wire of SG connected to one end of the coil. Ampere-meter with the diode parallel with the coil. He is tuning the frequency to read maximum value on the Amp Meter.  It is resonant frequency of the coil (here 1.8MHz)  Then, he connected the ground cable on the other end of the coil and the resonant frequency dropped to 1.36MHz

Experiment with the 2nd coil:  The same as above, this time the only coil resonant frequency was  1.2 MHz and when grounded, the resonant frequency was 1.36MHZ.

Conclusion-  Two different coils of different parameters when connected to the same ground, they both resonate on the same frequency.

That's interesting.


Cheers.

Little offtopic but not really...    In push-pull DC-DC converter there is a choke on output side after diodes or diode bridge and before the output capacitor. What is the purpose of this choke and how to compute minimal inductance of it ? Can it be usefull to convert HV spikes into lower voltage currents ?
