Kapanadze is fully aware of the fact that the frequency drops under full load.
That's why he referenced this scientific paper here :
http://publica.fraunhofer.de/eprints/urn:nbn:de:0011-n-1322533.pdf
in his patent WO2008103129A1 (second last page)
He wouldn't list it there, if it wasn't playing a central part in his invention.

This Energy is from BEMF.

Kapanadze not use BEMF

Kapanadze not use BEMF

Hmm, since you quote my post there, i have never said that he would "use" BEMF.
If he's got a resonant circuit in the secondary, then he is facing the normal rules
of a LCR circuit.
He just knows how to automatically adjust the resonant frequencies in relation to different loads.
That paper might be the closest reference to what he is doing that he was able to find.

@captainkt: Do you get substantially different results when you use
a) only the inverter without the HV
b) just the HV without the inverter ?

@All

OK, I think TK is using the spark gap as a switch. Like a relay or a mosfet. Every time the spark is on, there is a connection and the process starts.

Why am I saying this. OK, if you look waaaaay back to the Tesla Ozone Patent (TOP), you will realize that the biggest problem with that patent is the rotary switching that you need to make the patent work and produce ozone, which is high voltage pulsing. If you are working with relays, the switching is not fast enough and the contacts start burning up. If you are working with mosfets, given the loads, one small error and mosfets burn up. This has been the greatest hindrance to making the TOP work with modern components.

But looking at the TK device with the spark gap, it dawned on me that this spark gap could be used in the TOP as a switching device that will not burn up in a few seconds. By using the battery to inverter to MOT, the MOT secondary keeps the next section that  includes a coil of high inductance, a working transformer (MOT used backwards), a capacitor and the switching (spark gap) in a high voltage environment where the spark gap can be initiated by the normal TOP method.

I will try this during the week and report the results. I am so stupid to have wasted a few years trying so many different switching methods for the TOP when TK had been showing this spark gap working all along. With this method, the second MOT secondary is in series (used as step down) with the TOP method, you could have several of these in parallel or series, or you can use the output to a third identical stage for greater isolation and more points of energy return.

TK already said his TK coil was used to regulate the output to the bulbs. We know the bulbs were connected on one side to Earth ground so he could use the second MOT in reverse to the diagram and produce even higher voltage that would light the bulbs with one feed wire.

In the diagram below that uses the TOP method, the spark gap is used as a switch (and not just an impulse generator) and with the TOP method, you get a capacitive impulse when the spark is on, and an inductive impulse when the spark is off. That's double the bang and now there should be no switching problems. See the spark connection is shorting between the coil of high inductance and the second MOT (working coil) then it is in series to a capacitor. This is the TOP part mixed in with TKs high voltage instead of running it with 12vdc like we have been doing. TK may simply be using Teslas' damped wave TOP method.

PS1: I had been building a new device for nodding around but will put it aside and make this setup. If anyone tries this please be careful because I have received many shocks while testing the TOP method.

PS2: After the first MOT, you may need a FWBR to regulate the high voltage AC to DC.

@Xenomorphlabs,Yes I agree there may not be resonance, what kept me playing TK was two months ago I built a Tesla coil air core with primary at each end 100 watt bulb in series in centre then fed mains voltage to ends of both coils. I then used a car coil set up with variable oscillator to pulse secondary at one end with other earthed, I went through a few frequency's up and down to see if I could alter the brightness in any way suddenly the bulb exploded and I could put my finger in and touch the filament. I have shattered and melted and fused dozens of bulbs in the past but this was different , sent me deaf for ten minutes.Tried to replicate next day but fail when mosfet gave up.Spark gap seems more reliable and certainly plays a big part in my latest circuit. Regards

once i have posted on this thread, i could light a 1 watt lamp at the secondary after disconnecting signal generator, not many of you have looked into it. i still wonder what have caused that apparatus, i could not replicate my own experiment after,
things i observed were much like kapanadzes device,  frequency it operated at was 1.2 mhz,  and i held signal generator probes away from the coils and the Lamp did not respond,  (lamp did not dim at all)   
Any explanation why did this happened and why i couldnt replicate this second time?
i keep thinking i allready had the answer to the tesla device that time.

Without posting your entire circuit, it's impossible to understand what went on in your set-up.
Things like that get reported often (the impossibility to replicate), you probably hit an earth standing wave, then moved your clip leads a millimeter and went offtune.
Until you don't know exactly what the parameters of your circuit are, you are literally working in the dark.
Let's hope one day you can replicate it.

The lamp was lit as long as i have not touched the coils, i left it like that for half an hour or so while the signal gen was with its pos neg lead were away from the coils, about 1.5 meter away, i saw that distance did not disturb the light, brightness did not change at all. anyone explain this? im still thinking for 1 year now why did this happen and i still dont have my answer. any professionals around who can explain?


something i nearly forgot to mention is that at the time i did not have a high voltage transformer so i made 1 out of ordinary 220-12v volt mini transformers, i dissasembled them and made 1 like in the picture below which give me around 400 volts total connecting the signal generator
there is a mistake in the drawing where i say 0.4 volts 5 miliamps in, that was measured coming from the signal generator before the disconnection ,

Here is  one in a series of youtubes I did on pulsing coils that may show some of your effects. At 1.2mhz, one wire lighting of LED is common.
http://www.youtube.com/watch?v=P5zXe_iJzXc

I once held the pulse generator terminals with my fingers and a coil with an LED lit up 5 feet away from me. I never was able to re-do the effect. It was the weirdest thing ever.

Please concentrate on that what I say here. It is important to do not waste your time or to properly  isolate known science art from unknown science art.

Nothing special and nothing unusual I have seen on that video.


1.Every LC parallel or series resonant circuit is RLC circuit

2.Every coil, capacitor and most of resistors are RLC series and parallel resonant circuits at the same very time.... even if not connected to any other R or L or C and represent single electronic element of R or L or C.

3. Every coil, capacitor or most of the resistors have their own self resonant frequencies!!!!!

4. Every coil, capacitor or most of the resistors is resonating in self resonant frequency.. of
-series equivalent resonant circuit,
-parallel equivalent resonant circuit,
-combination of series, parallel resonant circuit . AT THE SAME VERY TIME !!!
BUT....
each  one of self resonant frequencies is different.
each harmonic of that particular self resonant frequencies is fed by energy of primary resonant frequency.

5. series resonant circuit "wants to" blockade every frequency other than main self resonant frequency  allowing maximum of amplitude only at that frequency

6.parallel resonant circuit "wants to" blockade  only one frequency and all of other frequencies  are allowed to pass.


What is filter and how it  differs from  resonant circuit.
The answer is: IT IS NOT DIFFERING AT ALL.
Coil or capacitor or most  of  resistors can be a filter even is it is not connected to any other R or L or C.

What is counterpoise of an antenna:?
It is a BALANCE  to main or primary of active resonating element.

example- every antenna must obey laws of conservation energy
 "Dipol antenna " placed horizontally looks like this
 http://en.wikipedia.org/wiki/Dipole_antenna

Say in the positive part of sign wave left arm is   active and right arm is counterpoise -at that particular very time.

Vertical antenna  ( say your car radio antenna ) weep  is  active and body of your car is counterpoise. (For HF frequencies is not that  easy..)

LW antenna ( Long wire) is a single end of wire connected to TX ( transmitter or generator)
generator body is than counterpoise to the antenna.
But overall length of the wire must be able to resonate at  frequency of choice, and additional tuning coil( and/or resonant circuit RLC) might be required to adjust counterpoise ( body of  generator- metal box ) so the counterpoise becomes balance
to that active  wire and represents  electrically equal balance to the active element.


Got the picture?


You just playing with antennas.
One of them is connected to transmitter  - generator
Second one is connected to receiver LED.

PS:
Efficiency of an antenna:
If your "dipole" type of antenna is 40m long it will be 1/2 of 80m wave=3.8 MHz That antenna will resonate at 3.5 MHz. and take most of your roof and back yard length. 
Now - You take this antenna and coil the wires
This antenna will than be on your table small and convenient and  it will be theoretically the same exactly antenna .
but there is the catch!!!
efficiency of that antenna a will be  very small.
 
That is why you guys are trying to connect straight wire to the radio to have better reception of  the radio wave.

every antenna  can be   used as transmitting and receiving antenna .

some of car antennas have small coil at the bottom or in the middle.- that is  for being able to keep electrical length of antenna and at the same time have height of that antenna smaller so it will become convenient in every day  driving.
BUT IF YOU STRAIGHTEN THAT COIL YOU WILL HAVE BETTER RECEPTION.!!!!!!!!!!!!!!!!!!!
Although there is one catch:
The capacitive component of that coil is part of resonant circuit, so when you pull that wire and the coil become straighten than electrical length of that wire my push it to resonate at different frequency than previously designed.
Also bandwidth of that antenna will become more narrow.
In general for FM radio this is not important. That antenna is broad band FM antenna with unacceptable parameters for professional.
You can as well put piece of wire instead of THAT ANTENNA AND WILL WORK AS WELL.
And the reason  for it is  the signal strength is so big that many times you could  put just  one centimeter  of wire and you will still be able to receive something.
That is what you doing now my friend.. just playing with known art.

Is it worth of your time..?
YES it is..
 It is like trying to trying to open the door  with your nos...You may experience something that others will never find out.And that may lead you to discover elements of mechanism of your nos playing with the handle.
Rest of the world decided to be uneducated in this area  or simply never thought about it.
But if you try to open the door that is already open than you have to create imaginary door. That leads you to graphics and art of graphics.

There is no motion that does not bring you to interaction and evaluation of that interaction..(within area of your 6 senses)
However there is ignorance to factors of interaction qualified as non important
