Hoppy:
   IF you have, I haven't seen it (the rat). Maybe you can refresh my memory of it, (before it multiplies) , as my memory is not what it used to be.
  The image of your 1000w bulb lit up would be a good start, if you still have it. Showing the effect from the Kacher, also.
As we never saw any videos by you. Or did we?  All I remember were dim bulbs, or lighting a smaller bulb or two from a 240w PS. 

   I can dimly light a 25w incandescent bulb from just the Kacher's output, alone. With No connection to the 28 turns coil, or turning on the induction circuit. Although my super simple Kacher circuit is not a very strong one, but it shows that there is some interaction going on with the yoke and grenade coils circuits.

   I would really like to see what Geo has come up with lately.   Holding my breath...

   

Looking at the Stepanov setup —which for some strange reason no one seems really interested in— I was wondering all along what diodes are good for when AC goes in and AC comes out of an assembly consisting of just coils and capacitors.

Hi Zeitmaschine. The fullwave bride rectifier diodes is what does the frequency doubling.
They convert 50 Hz sinewave to 100 Hz half wave pulses. I would guess the resonant circuit made up
the capacitor and the L from the output transformer primary winding is used to convert the 100 Hz pulses
to a sinewave, since you should get a sinewave in such a resonant circuit. Also I think the resistor is probably used to
limit the Q of the resonant LC circuit, which would limit the max amplitude in the resonant circuit. You then get a sinewave out
at 100 Hz on the secondary of the output transformer. What benefit are you seeing from using such a frequency doubling setup?

I'm sure you will remember one of the best ones, the 4KW rat under the straw video: https://www.youtube.com/watch?v=r-9MqTGywdI

The best one I cannot find now. Its the one where he is sitting down in front of the device with the bulb under the table. He is discharging the red Wima cap whilst watching the meter reading.

As for the image of my 1000W halogen bulb, its only the bulb as I did not do videos, so cannot show the interraction with the Kacher. I no longer have the photo stored on PC, so you will need to look back in the thread for it.

  What rat under the straw?  I see no rat, not even a mouse.
  Are you taking medications? Mind altering drugs, etz...
  You always seem to be able see, what one one else can see.
 

You don't always see the rats but sure can smell them!  However, the rat is plain to see in the other video but I can't find a copy of it since Ruslan took down his collection.

   I'll await for further proof of the rat in the works.  Maybe I need reading glasses, or a rat magnifier lens.   
   Sniff,  sniff, sniff.  No rats here,  sniff sniff, no rats there.  I don't smell a rat. Smells more like Bull shit...instead.
 

LOL. No just remove those rose coloured specs.  Anyway, enough of the banter; you need to get back to the bench and replace that Mazilli with a PWM push-pull.

Hi Zeitmaschine. The fullwave bride rectifier diodes is what does the frequency doubling.
They convert 50 Hz sinewave to 100 Hz half wave pulses. I would guess the resonant circuit made up
the capacitor and the L from the output transformer primary winding is used to convert the 100 Hz pulses
to a sinewave, since you should get a sinewave in such a resonant circuit.

There are two possibilities to get the double frequency output, which should be high voltage: 1) Use a standard high voltage transformer (e.g. from microwave oven), this creates sinusoidal high voltage at 100Hz. 2) Use a low voltage transformer (e.g.) 12V/220V and use the 12V coil as primary input. The pulsed 220V DC at the 12V coil will drive that transformer hard into saturation which creates asymmetric high voltage spikes at the 220V secondary coil. I'm not sure yet what's better.

Also I think the resistor is probably used to limit the Q of the resonant LC circuit, which would limit the max amplitude in the resonant circuit. You then get a sinewave out at 100 Hz on the secondary of the output transformer.

The resistor is needed to discharge the capacitor. Otherwise the capacitor works like in an ordinary DC power supply.

What benefit are you seeing from using such a frequency doubling setup?

The pump frequency of a parametric oscillator should be twice the natural frequency of the oscillator. Wikipedia: »If the parameters vary at roughly twice the natural frequency of the oscillator, the oscillator phase-locks to the parametric variation and absorbs energy at a rate proportional to the energy it already has«

So »absorbs energy« from where? From the high voltage coil (not circuit) which collects that energy from the environment (aether/space)?

If there is ever a chance that those Stepanov and Kapanadze setups are real, then I think I'm to 90 percent close to the solution. I'm just not sure how to construct the feedback part.

Zeit:  It's not that no one was interested in what Stepanov showed,  it's that there was not enough information on that device, to be able to fully replicate it.

Watching closely reveals more information than one would expect in the first place. Kapanadze's 2004 video shows also a diode bridge and a (silver) capacitor. Is it a DC voltage supply or rather a frequency doubler? You decide.

BTW: This topic would rather fit into the Kapanadze thread. Unfortunately there is discussion going on about all and everything, except Kapanadze.

  After you, Sir.  Please, lead the way to rat-less devices.
  I'm still waiting for Ypok, Geo, or anyone to show a real working model. That does not smell like,  like well, you know...

   I'm not sure which way to go, at the moment.  And, I still have not found a commercial TL494 board with PWM, and with at least 300-500w output. But, I'll bet that it already exists, somewhere.  At Oleg's bench, I presume.  But, it seams like no one is willing to go talk to him, and bring back a sample board. So, we continue to plod in the darkness.
 

Nick,

The TL494 / SG3525 are PWM chips, so you only need a powerful mosfet output stage. You are unlikely to find a suitable commercially built board, so a DIY approach will probably be necessary, unless you wish to plod along in the darkness.

Reversing the coil connections results in no effect.

The video of your setup would help.
In result you want to get minimum consumed current as possible from the power source and contain resonant circuit while covering only resistive losses. The transformation on the output should not be direct magnetic field part.

Just to get idea - here is one of fresh experiments with lighting microwave bulb on the output while the current in consumption stays on minimum when doing modulation of two signals:
