Indeed, the usual electronic operational principles prevent the Akula's circuit and transformer from exceeding unity O/I power ratio, unless something unconventional happens in that transformer. 
The conventional behavior of the transformer in this circuit is pretty accurately illustrated by the simulations posted in this thread.

As I said in beginning, the trick is in transformer... :D
And what effect needs to be there to trigger COP >1 condition - still not very clear.
Perhaps Grum had it very close with adding noise to circuit and having transformer fully ringing between each sharp pulse?

Cheers!

Dear Avalon.

Welcome to the thread, Oh and by the way I'm Grum, not Pete !!  :)

Sorry your Sim looks good but it does not show very clearly the 2 to 3 second dying oscillations that I am seeing after power off !! Just need some more noise !!  :)

Cheers Grum.

Hmmmmmm. I would have thought the contrary as at resonance usually amp draw goes down and voltage goes up.

Amp draw goes down once the resonator is filled with energy.  But that's a temporary "overdraw" condition.  The problem is that maximum voltage equals maximum current when the voltage is zero.  That's where the losses are, in the resistance of the wires.  So resonance is a power draw.  The amplitude of the resonance gets as high as it can which is determined by how much power can be supplied by the source.  For example, if someone can get a transformer to resonate, they can measure the power draw of the transformer at the resonant frequency, and just below or above the resonant frequency and compare.  The point is to not take anything for granted.  I have never done this, so I am not telling you this will exactly happen, but the measurements should be made.

I am not convinced that you will be able to make the transformer resonate in the circuit.  However, chances are you could if you drove the isolated transformer with a swept sine wave from a signal generator.

The power draw at resonance depends on a few factors, "Q" factor of the coil is one factor and also the level of voltage used and achieved as well as the capacitor resistance and frequency.

My small Tesla coil primary with feedback oscillator has 1 mm wire and I can get a fair bit of activity in it with only 300 mA input, very much more watts than the few watts input, it gets up to like 200 Watts or so activity but the input at resonance is more than when not, when not at resonance the input is almost nil.

That's why I built my bigger Tesla coil with 1 mm wire in the secondary, how many Tesla coils you see made with 1 mm wire secondary ? I worked out a rough "Q" of 6000 or so for it. 3.2 Ohms resistance or is it only 1.6 Ohms resistance I can't remember, 4 mH and 760 kHz. I think it has a bit more than 4 mH inductance, been a while since I measured it.If the resistance is only 1.6 Ohms then the "Q" would be closer to 12000. Which would be good.  :) EDIT I just worked it out by wire length and resistance for the wire per klm and it is more like less than 2 Ohms, so I'm gonna say the "Q" is more like 9000 for the bigger Tesla coil.

Circuit Sage "Q" factor calculator.
http://www.circuitsage.com/tools/tool_view&tool_id=17

I would say if people want to resonate coils the coils should be high "Q", this seems to be ignored. Resonance can change the impedance of a coil but it cannot change the DC resistance, the DC resistance will always burn up power. The oscillating losses can be calculated by the DC resistance and the oscillating current ect.

It makes no sense to me to resonate a coil with a lot of DC resistance, it will get hot and the heat will be produced from the input supply's energy.

Cheers

P.S. Of course the exception is if resonance is wanted to increase the voltage output of a transformer ect. and the power dissipated is not a concern.

If we have a coil which has 140 Ohms resistance it burns enough power making the current flow through it once not to mention non stop oscillating current.

If a coil is going to act as a high resistance to reduce input it makes no sense to have it resonate.

The near infinite resistance of parallel resonance can reduce input in some situations. It depends on stuff.

The reason you are seeing dying oscillations is discontinuous conduction mode which happens when ripples in inductor current cause polarity switch of applied switch current to reverse.
This could be a result of a poor quality inductor with high parasitic (stray) capacitance (C). When the switch is off the secondary coil still has energy equal to C * U(out)^2/2. Hence - dying oscillations.
There is no free energy here.

... it does not show very clearly the 2 to 3 second dying oscillations that I am seeing after power off ...

Farmhand:

This is a statement that might suggest some interesting experiments to you:

In simplified terms:  Let's say, you connect your signal generator to an LC resonator.  The wire resistance is 2 ohms and the peak-to-peak voltage is 10 volts.  There is some measurable power A going into the resonator.

Now say you have the same LC resonator, same inductance and capacitance, but the wire resistance is 1 ohm.  You connect the signal generator and this time the peak-to-peak voltage is 14 volts and there is some measurable power B going into the resonator.

So, the AC voltage increased, but that means more current going through the wire.

Is power A > B or is power B > A or are they roughly the same?

Let's say for the sake of argument that they are the same.  So that means that there are nil returns in terms of power drain reduction when you lower the resistance of the wire in the LC resonator.

Lower resistance equals higher Q factor, and higher voltages and a narrower - 3 dB bandwidth, but not necessarily reduced power burn-off in the resonator.

There are issues of how you couple to the LC resonator and source impedance and source voltage that I did not touch on, but I assume that you get the main point.  The by far far easiest way to do these tests is with pSpice or even that Java simulator.

Yes but MileHigh try an LC circuit with 150 Ohms resistance and then to get the same activity in the tank you'll need more input. It all depends on why you are doing it and what you want to achieve. It's all relative I agree.

It also depends on if there is a limiting load or not as well.  If there is no load why do it ?

Cheers

P.S. I'm no expert but I think I see in my setups I can alter the output impedance by tuning.

I want to state at this point something Tesla said in the Colorado Springs Notes, Tesla clearly stated, July 7 1899 page 65 see attachment that a high rate of transformation is better for power transmission, but for signals (small power levels) a great resonant rise can be beneficial.

Now when transmitting power I think the idea is to tune the machine to the load so as to be most efficient, perfect resonance is not the goal, but the device should be capable of being tuned to resonance.

Tesla coiler's know that to get the best performance when making streamers the primary L/C should be tuned to a bit lower frequency than the secondary because when the secondary breaks out in streamers it's resonant frequency drops due to the load. The Spark makers transformer has a load, which is the streamers. They limit the voltage for the input applied but the transformer is still "resonant".

As for resonance in these Akula devices, I don't know, there could be a use for it in some part of some circuit. But to me the circuit seems odd and I see no replications I can believe.

MileHigh, you are correct though. I know this because I see in my older video's with my small Tesla coil transmitter and receiver setups that when the transmitter is tuned to resonance and the receiver has no load then the input can be higher than when the receiver is lightly loaded. That is because the load is just enough to limit the voltage in the tank to lower the losses. However a tuned setup should be able to be tuned to have a low idle input, then when a load is placed on the receiver the transmitter input goes up, I have also shown that. It is all in the tuning, tuned circuits need to be tuned. And to do that the operator needs to know his circuit to some degree, experimenting with tuned circuits is fun and very educational in a practical way.

The best and simplest tuned circuit is the two Tesla coils with one of them driven by 12 volts and switched at full resonant frequency, with the ability to vary the driving frequency and pulse width and to tune the L/C of the two primaries and the two secondaries. One can learn a lot from such a setup. Using a feedback oscillator can be good but it is different to driving at a frequency that is manually varied. ( a function generator is ok but the power is not enough ) FG good enough to light neon's and see the distribution of potential though.

..

P.S. I want to build a "H" bridge circuit to switch a variety of coils, previously I just used DC pulses, switching the primary coil both ways will help for more output I think.

You guy's still dont get it

The key to free energy is ionization

The coils (chokes) have to separated with enough distance that the charges cannot rejoin before they are collected.

Look at static eliminators

A choke pulsed with a neg pulse will have a pos bemf

What is the wavelength of the driving pulse compared to the length of the choke in your scenario?

Farmhand:

Just to explore the loading issue and resonance some more.

The child on the swing example:  You push harder and the size of the swing increases.  Then it stabilizes at the larger overall swing amplitude.  So you have to put more energy into the push and you get a larger swing that burns off 100% of your push energy.  You can look at it another way - the resonator is adapting itself to your push to extract exactly how much energy you are willing to put into it.

If the resistance is low (air resistance in this case) then you get a higher swing for the same energy per push.  If the air is thicker the swing goes down.  Push harder and the swing goes back up.

So in essence the swing adapts itself to "match your push."  So what does that mean for the power consumption in an electrical LC resonator?  Or to put it more accurately, an LCR resonator.

Here is the question:  Can you think of the design for a circuit that will simulate the swing and the pushing?  See that can be fun.  You have a physical setup and to test it's behaviour you design a circuit and then run the simulations and play with the variables.  The goal for the test would be to make the power consumption measurement for different resistance values associated with the LCR resonator.  You could drop a power measurement probe onto the schematic, and then see what happens to the average power consumption when you change the "R" part of the resonator.
