Selfrunning Free Energy devices up to 5 KW from Tariel Kapanadze

Why not make a smaller one?

Yes, a smaller device can be made, it just will not be an exact replication of Kapanadze's. e.g. see Meyer's rod device.
If McFreey's operational principle is correct, then smaller device will require stronger confining fields among other changes. Lorent'z forces, cyclotron radius, mean free path of beta decay products, frequency, skin effect, etc... all play a role in this.

An electric motor works just as well regardless of its size, a transformer works also just as well regardless of its size. But free energy may only appear above a certain physical size? Very odd.

It is not odd at all. A nuclear reactor will not work below a certain mass. A chemical explosive detonation does not happen below a critical mass and pressure. Particle accelerators need to be sufficiently large to accelerate particles to high velocities. Photons need to be above certain energy to ionize matter (1GHz will not ionize meat, while gamma photons - will).

Any time an operating principle involves random processes (e.g nuclear decay, molecular diffusion, Berkhausen effect, etc...) it is strongly affected by probabilities. These probabilities strongly depend on the mass and size on the medium in which the process takes place.  There is usually some break-even-point at which the probabilities are high enough so that the process does not die down spontaneously. In a nuclear bomb, the critical mass has an origin in this principle.

Transformers do not rely on any random effects for their operation, thus they are not affected by size very much (if magnitude of their power transfer is neglected).

And I would appreciate any ideas about the basic principle of the above, because it could be also the Kapanadze principle.

Frankly, I don't know.
The 250mA output from the Velleman signal generators seems insufficient to saturate even the old Soviet ferrite.

There could be something unconventional happening in the core or in the copper strip itself... or both:
e.g. As described in the IEEE article by Konrad & Brudny, where an electric field of HV discharge affects the magnetic permeability (and inductance) of a piece of ferromagnetic core (appears to be another method to vary the inductance).

NOTE:
The Velleman signal generators used by the STAAAR team, had no synchronization inputs, thus they could not be synchronized in phase. Even if their frequencies were set to an integer multiple of each other, their phase difference would slowly drift over time.

Also, it is important to notice that the 1-turn copper strip winding is perpendicular to all the other windings (as viewed from the toroidal topology).  This orthogonality is uncommon in conventional transformer designs.

Well call me crazy, but if you charge a coil so that it stores 0.5 Joules, then change the inductance to 5 Henries there is still only 0.5 Joules for the coil to discharge.If what you propose was true it should also be possible to do the reverse, charge the coil with 0.5 Joules then change the inductance to less and get less energy out,but where would the energy that did not come out go ? Same with the increase of inductance to attempt to get more energy out where would the extra energy come from ?It's kinda like saying if we charge a 50 liter compressor tank to 20 PSI then somehow change the tank to a bigger or smaller the energy in the compressed air would change.Would it ? If the tank size was halved it would mean the pressure would be greater, but it would take energy to compress the air more as the tank was made smaller.Cheers

If you charge a coil at 0.5 Joule then change L 10 times more while keeping I constant you have an amplification of the energy of 10.
The math speak themselves.
The reverse is also true, if you charge at 5 Joules and switch back L 10 times less you will have 10 times energy less.


It was suggested those speculative hypothesis (better than nothing).
Energy come from:
1) Come from ambient heat (cooling core).
2) Time (time distortion around the device).
3) Gravity (gravity distortion around the device).
or 4) Law of conservation is invalid, in both case, creation and destruction allowed (highly speculative).


For your tank analysis you are correct, it will require a certain amount of energy to reduce the volume of tank, the energy needed to compress air would be equal to the energy of the compressed air in halved tank (if I neglect losses due to compression).
But in the inductor example shorting a secondary with a Mosfet take virtually no energy, as verpies noticed to me, the main problem is the losses when you charge more than 0.60 Tau.


Maybe a BJT or a high frequency Mosfet would control the input current to charge the primary inductor and then stabilize it (dI/dT= 0) opening the short and discharge to load.
The process must be very precise and even computer/microchip controlled to minimize the losses.


The other possible way are varying permeability by mag-amp (how energy is needed to saturate the core ? and how much is returned to source ? )
or a rotor that alternate magnetic and non-magnetic part, profiting from the change in L and the magnetic attraction (negative torque), while of course discharging the coil completely before the magnetic material part in the rotor leave the magnetic circuit of the stator, thus avoiding the magnetic drag.


SRM.

That is true if increasing inductance (L) or keeping current (I) constant, does not cost any additional energy.

Try to pulse-saturate the primary ferrite (not necessarily with a spark). Would be interesting what happens.

Many thanks for your reply. Do you have any ideas how I might practically implement your suggestion?

Further tinkering today saw with a 2.2 mFD cap across the open link between primary and secondary Ferrite rings. Still with 1 to 1 to 1 ratio. With 10 volts P/P in we saw 80 volts P/P at output. This only occured at around 30 kHZ I am assuming a resonant responce?

Would I be right in saying that the physical alignment of the Ferrite rings, ie, 90 deg shift does not matter? After all the flux is linked by the center winding.

Any observations welcomed, Cheers.
