If there are countless resonances generated by the spark gap, how are they received and the power generated?

Many people have experimented with Tesla coils and no one has shown anything interesting for an increase in power. Facts: all tesla coils operate rather at frequencies> 800kHz. We don't know what will happen when we reach <100 kHz? maybe it will be the same but maybe nothing more than the right frequency with a narrow range is important! What frequency could it be? Kapanadze only once mentions that it is about 200kHz.

if you  look  at  picture from above

you see that at max resonance you  have significant  power  increase  but  at 210khz   and 228kHz  you have quite wide range of frequencies at 75%
of  its maximum resonat  power   and  that energy is  ready  to be used by  drifting  Tesla structure.
You are  not interested  with big power for    your experiment.
But if you  use  single frequency generator  than you  limited  to  just 218.6 kHz  at 100%  of  power
Your Tx  and Rx must not be drifting   more than few hundred Hz.
So spark gap is not efficient but  is convenient  way    to  go.
Viziv Tower operates at 20kHz/18kHz so  if you say that: most  of Tesla coils are  resonating at 800kHz  it is   only your  own  opinion   shared.

Thanks Wesley for all the details.

Here are my v 2.0 secondary Tesla coils side by side with the first set I tested.
The new ones are wound on 39" inches long 4" i.d. pvc sewage pipe.
1400 turns of 22 AWG

Wesley, I have a question regarding the primary coil. Could I use 3/8 flexible copper pipe instead of Litz wire?... which is best?... does copper mass matter?

Kind regards
Luc

Sweet luc. Are they 3D printed ends inside pvc formers?

When the spark gap works, it acts like a frequency spectrum noise. Do you think that this noise turns into a pure sine wave and it's all in resonance? If this were the case, the antenna adding the frequency range would suffice. That would be great but too optimistic.
The antenna distance depends on the frequency, so to increase the range you need to use the lowest frequencies. Therefore, Viziv Tower will eventually have to operate on Hz or kHz when there will be more transmitting antennas.

- Will your power transmission work without the top load capacitors in place?

It would have to be tested to confirm but I guess the results would be like removing C in an LC tank circuit. Would it still work without C?

- If the top terminal is one plate of a capacitor, where or what is the second plate?

That's an interesting question!...to which brings another question. Must a capacitor have 2 physical plates to qualify or even function as capacitance?

- How do capacitors work?

I'm no expert but I think it's an electrostatic charge that clings to the surface of a dielectric material.

btw, for the record, I am not an EE (and I don't believe I've ever claimed to be).

Thanks for your honesty. I must of assumed you were an EE because of your knowledge and certainty on the subject you've displayed over the years. 

Kind regards
