So my question is how can I find out how much wire length I would need to produce 3400pF with a given wire AWG.

Hi wattsup,  you can use this calculator:

I would say the outer fat coil of 6 turns is his capacitor. It is positioned way too far from the main coil winds to be working at inductive or close coupled levels, hence it is far enough to only utilize the coils capacitance and still appear to be used as a coil for the functional deceptive value.

It is made out of coax cable in the green box, and so is it in the newest device.
What he calls "primary" in the aquarium video looks like a tubular capacitor with
inner aluminum tube and outer copper sheets. Romero has pointed that out too a couple of pages ago.
The fact THAT TK still calls it primary which one would only use if to describe a transformer action
is interesting. So either that tubular capacitor still exerts a magnetic effect on the secondary (which i could not explain at all to be feasible) or he is looking at the whole thing as an electric field transformer with no significant magnetic component. But even for that the distance between them is too large.
Keep in mind that if he wanted to maximize a magnetic effect in that transformation he would
use iron or ferrite in the core of the horizontal secondary.
Instead he uses non-magnetic brass, which reduces the inductance of the secondary even.
This puzzles me for quite some time now.
That and the fact that he uses crossed windings for cancellation on top of it, is a strong indicator that
he seeks to create negative inductance in the secondary while maybe only wanting to excite the background
of the windings with high voltage. The same method is also described in "certain" files



@Sasa649: This is a Kapagen replication?
One note concerning your video. Forget about the clampmeter (for measuring current).
It does not give correct readings at high frequency operation, it is designed for 50Hz only.
That is the most common measurement mistake with these devices.

hello everyone from serbia
my first coil two light bulbs 100+60 watts lightning, I have to make proper measurement to prove it, is it making extra energy. I use 16 mm ferrite core length 400 mm and trafo from microwave oven. But since I do not know anything about el. power this is amazing for me. I just followed videos from youtube and forums and it is working now. Needs a lot time and effort to make it useable for everyone. And I also need to build flyback to make it autonomic.

 Hmm.. Very funny.. Is that clothes line connecting the useless connector just above the dual spark plugs? ROFL

 heh.. Well I wouldn't give those guys the time of the day lol. Just keep with it.

If he keeps his design a secret like some others do, then we will never know.

I like it the COP looks around 4


Perhaps you can get hold of a MRF454 NPN RF power transistor that is usable to 30 Mhz and 100 watts.  Need a bigger Tesla coil for 400 watt load!


Fet use is difficult but possible to use IRF840's good for 60 watts RF @ 30 Mhz. Requires accurate biasing and 15v zener to protect the gate.  You also have a lot of stray RF leaking up the battery supply lines. Better filtering chokes would keep more going up the Tesla coil as you could be wasting 20% right now.

This may have pushed TK to start thinking even more out of the box and he may have started experimenting using coils as capacitors.

Also, on the TK coil which is the output, any classical capacitor requirement (such as that in the WNYg device output) at that point would have meant more wires going into the green box, which there are not. So now I am more then sure he was using a coil as a capacitor wound on the same output coil so no extra inter wiring between the TK coil and the green box is required. I would say the outer fat coil of 6 turns is his capacitor. It is positioned way too far from the main coil winds to be working at inductive or close coupled levels, hence it is far enough to only utilize the coils capacitance and still appear to be used as a coil for the functional deceptive value.

I think you're on the correct path.  At least a path I'm traveling on now...
TK had what appears to be a coax cable in the outer copper tubing and we know coax cables make good capacitors.


Just an idea I'm playing with.

PS - I see others have mentioned this already....

I plan to start production of desktop generator CE, as a toy for now. I make small Kacher only because a large I do not have cable.
Yes, the power output depends on the transistor while it is true, above its ceiling is not to jump. I have already said - this is just the beginning, the beginning of something big and global.
Now think how to make a self powering.

We share the same vision! I would love to run two off 3ft high tesla coils CO-PHASED 1000 watt drivers for 4000w loads. BUT big problem for many people if this goes global you are in effect transmitting strong RF around 1-2 Mhz typical and in small number of usage may not be an issue but a SERIOUS problem if everyone starts to make these devices for FCC regulations etc is illegal in many countries. You will get "men in black" knocking on your door. People need to be aware of this when making spark gaps systems  and large antennae you will be transmitting for thousands of miles!
