Dear Magpwr.
Was I on the right track ?

Excellent. it is directly related to

https://youtu.be/aJJW8qqa1O8?t=166 ( tariel's helper got shock from HV)
so we are talking about similarity and properties of capacitor that has been made like coil , however the from the components of impedance
a- resistance
b. inductive reactance
c- capacitive reactance
the capacitive reactance depends from size of inductor conductive surfaces.
Bottom line is:
Tariel started from spark gap
later on told me that spark is unstable and he needs to move to electronic HV impulse generator
here:
https://youtu.be/IAPe3DiYt2o?t=579please note that I was NOT sure at the time I have created this video -of- if what I say, is what was done by Tariel .( tariel's helper who assembled this device for the show)
SUMMARY :
I wanted to point here at role of capacitive reactance of conductor where we are getting:
a- the higher the capacitance the higher is voltage in the coil (coaxial cable)
b- spark is a form manifestation of high voltage with no difference to the fact , that we are dealing with static electricity or just capacitive reactive component of impedance.
c- spark and plasma looks like it is not essential to have it ,It could be just HV impulse as it shows at number of following experiments after Tariel Kapanadze ( Ruslan, Akula)
d- interesting is that when I have made video with Glenn Elmore E-line , similar to Goubau transmission line or Summerfield
http://aeptransmission.com/ohio/Barnesville-Summerfield/https://youtu.be/sweXFKSXMxo?t=37I have noticed certain similarity to SR ferrite kielbasa with wire in the middle,
Goubau is two cones creating "sort of" invisible pipe with center conductor in the middle but this conductor has insulation in the middle serving as a medium slowing speed of electromagnetic wave
Glenn Elmore does not use insulated center wire but he uses set of ring plates inside the cone ( dielectric)
In all of these transmission lines frequency used is high 50MHZ and higher.
but if the distance between center wire and outer wire is big and there is ferrite pipe in the middle than we are dealing with;
a- periodic mechanical change of domain polarity inside ferrite kielbasa pipe.
b- we still have center wire like in coax or like in transmission line.
c-
- the frequency of square impulse is not so low. ad c:
if you take rectangular wave form -that one, is made out of zillions of transverse wave forms of different frequencies.often of very high frequencies.
Take an example :Even if you interrupt regular DC circuit with the regular switch than you have zillions of transverse wave forms at rise-time and fall-time of that impulse( the higher the voltage the more evident they are) and every time you interrupt it with the switch you have ionization of air taking place.
You may say that with few volts from DC battery there is no visible ionization taking place. However Tesla coil is sort of transforming "voltage multiplier" the higher is voltage potential the lower would be the current but the more ionization would take place.
Tariel first started build his devices based on Spark gap because spectrum of spark has zillions of transverse waveforms.
by that Tariel was never worry what is the single transverse component that is going to do the job in within spark spectrum frequencies. there was always one present and ready for him to interact.
during spark generation when spark gasp increases or conductivity of spark electrodes surface changes there is always any neighboring frequency in within the spectrum ready to interact
Than I start to think......
What is if any the common link between:
1. spark
2. spark gap distance
3. spark generator -( impulse generator) from water heater
4. square wave impulse and its length
5. DC square wave rise and fall time(there are AC components)
6. Transmission line
7. SR middle center wire in pipe
8. coaxial cable
