Kapanadze Cousin - DALLY FREE ENERGY

[John.K1]

Guys, may I ask you as it is not clear to me. The measurement of resonant frequency of serial tank circuit is different to parallel one. In Parallel we are looking for highest amplitude, in serial for lowest.  What is the grenade coil?  For me it looks like capacitors and inductors (and resistor) in series?  Kinda confusing for me . Can somebody make it clear for me? Thank you guys.

The Transmission line theory might be useful and because the grenade coil is also inductive element where the wave propagation delay is different than in plain cable.

Jonh.K1 - every RLC resonance circuit includes resistance where series resonant circuit have resistance of power source and the paralel resonant circuit have direct connection to the coil so the resistance is much lower. This is why the resonant frequencies are different with same LC values.
For the grenade coil we need to look from both perspectives as it is being used as part of induction heater circuit and also as the recever from RF from Tesla coil. So the both transformer and RF transmission line theories have to be applied there.

The serial resonance has low amplitude in resonance because the induction reactance goes up  and capacitive reactance goes down. In other words, the volume of capacitance decrease in resonance point .
I have seen Eric Dollard speaking about the Transmition Line Theory. I might take a look at that movie again as i didn't pay much attention to it last time. You can find it on YouTube.

What is the ground plane in the configuration? what is capacitive component? a transmission line has a capacitive component which impacts its working frequency/impedance. if the transmission line is open ended then the 2nd wire is irrelevant for the most part since it is mostly capacitive. This is antenna theory, the ground wire matches the grenade coils length thus this is its ground plane, its matched ground element.

The Kacher radiator coil is part of this, as well as the 25 turn x 2 coil, all of these will impact the operation and its resonant point.

I would use a capacitance and inductance meter to determine actual values and see what the readings are in relation to the primary coil against the other coils in the arrangement, check this against the desired operating frequency (mathematically), then see how this lines up with the actual results when all components are in place (coils). Then solve for the capacitive component to align the coils to the desired operating frequency.

remember the kacher is the source (kicker/transmitter), the 168 turn coil is the resonant tank (mixer?)and then you tap the tank for power, the capacitors are required to tune the tank circuits, store energy and offset the phase shift of current and voltage due to inductors.

I find the tesla coil (Kacher) is 1/4 wave of the 168 turn coil, at least in my setup.

Thanks starcruiser,

interesting post.

So i put my grenade coil above a copper (conductive) plate and used that as my return wire.
I used my pico-pulser to pulse one side of the grenade coil with the copper plate connected to the minus of this pico-pulser
Then as with time domain measurements, i left the other side of the grenade open and scoped the input side for a reflected signal.

Normaly if i use this on a piece of coax (10m) i can clearly see the reflected signal coming back from the open end of that coax (positive pulse)
and when i short the far end the reflected pulse returns as negative.

But with the grenade coil on the copper plate, no reflections are seen, positive or negative (when i short the far side of the grenade to the copper plate)
So this test tells me that the grenade is not acting as a transmission line or the inductance of the grenade (122uH) is to high and interferes with the pulse.

You can try this nano pulse on Tesla coil with its top load over inductor of grenade coil. Then see how far signal goes inside of it with CFL over as indicator.
Would be interesting to see.
