Selfrunning Free Energy devices up to 5 KW from Tariel Kapanadze

With battery? I don't think so. Like a.king or Mike told the weight of device was around 6 - 8 kg. Good battery have few kg.
I think, there must be capacitors bank. Capacitors are slight. And few mF (maybe 10 - 20mF) should be enough for 2 sec. powering after switching off.
base of the generator must have a high current efficiency and Cap bank is only to temporary put energy to stabilize the current on output.
Caps should be charged like in pulse power supply. And we have OU pulse power supply... ;-)

It depends on what type of batteries he could be using but I take your point about the weight assuming LA or NICAD but Li-Ion or poly is a different matter. I'm not looking at an OU element in this, purely how this could be achieved using conventional circuitry with trickery. Remember that Romero strung many along for a long time until caught-out.

His circuit L1 is the classic prerequisite for ferroresonance.

Maybe. Ferroresonance is still a weakly understood phenomenon. 
Often it is associated with a magnetic field varying independently in two or more dimensions.
The attached article states: "Ferroresonance is a widely studied phenomenon but it is still not well understood because of its complex behaviour."


This is what Wikipedia states about ferroresonance.

Ferroresonance can occur when an unloaded 3-phase system consisting mainly of inductive and capacitive components is interrupted by single phase means.  In the electrical distribution field this typically occurs on a medium voltage electrical distribution network of transformers (inductive component) and power cables (capacitive component). If such a network has little or no resistive load connected load and one phase of the applied voltage is then interrupted, ferroresonance can occur. If the remaining phases are not quickly interrupted and the phenomenon continues, overvoltage can lead to the breakdown of insulation in the connected components resulting in their failure. The phenomenon can be avoided by connecting a minimal resistive load on the transformer secondaries or by interrupting the applied voltage by a 3-phase interrupting device such as a ganged (3 pole) circuit breaker.

Is this the same phenomenon as the 7th harmonic of 60hz fed flurescent light ballasts where Electricians have to oversize mains and distribution wiring to accomodate this wattless component of current circulating through the entire electrical grid.  The power companies admit they don't produce it but they are pissed they have to invest more money in their conductors to circulate it so they don't oveheat and become resistant to the exciting power scource?

"Power - no"  How that can be? Would you care to elaborate in layman terms?
Thanks..

Simply if I increase the voltage three times then the current will decrease three times.  Their product will remain unchanged no matter what I do (except for the RI^2 losses in practice).  I cannot increase both the current and the voltage without playing tricks with the phase between them.
And if I play phase tricks then I can increase both the average current and the average voltage, but the problem is that power does not equal  average current * average voltage.

P.S.
"Average' can signify the arithmetic mean [ (a+b)/2 ] or the geometrical mean [ (ab)^0.5 ] or quadratic mean [ ( (a^2 + b^2)/2 )^0.5 ] also known as root-mean-square (rms)
Power * Time = Energy

What happens if an ordinary 50Hz transformer is operated with 50Hz grid frequency and, let's say, 5KHz high frequency at the same time by means of different primary/secondary windings? If there is a strong BEMF at 5Khz (square wave) in the core then (Rhythmodynamics again) this could influence the power consumption/flow of the 50Hz circuit, I guess.

Yes, there will be influence.
1) If the 5kHz winding is oriented in the same fluxwise dimension (not to be confused with "direction") as the 50Hz winding then we'll have conventional saturable reactor or magnetic amplifier without DC bias.
2) If the 5kHz winding is oriented in a different fluxwise dimension (e.g. fluxwise perpendicular to the 50Hz winding) then there also be an influence, albeit a different one than in pt.1

I already discussed the differences in Reply #11672.

P.S.
"Fluxwise" means relating to the direction of magnetic flux.  e.g.: all wire loops wound on a toroidal core transformer are parallel fluxwise, but they are not all parallel spacewise.
