Re: [TCML] MAX SPARK FOR FIXED VOLTAGE

Hi Dex, 

There is much in the list archives about this, but basically, spark length goes as SQRT(power), and thus is only loosely correlated to terminal voltage.

I have a good question I don't know answer to.
QUESTION:
What is aproximately maximum spark lenght possible for a given output voltage 
Tesla system generates?
 
Regardless of the efficiency,how long spark can be produced by a Tesla-type 
impulsive devices with voltage levels:
1) 100 kV
2) 200 kV
3) 300 kV
 
Can a high power impulse source,like a Tesla transformer,put out a 10 feet long 
spark with 'only' 100 kV voltage peaks?
To accomplish that it is free to use any power input level,any size and shape of  
a terminal capacity,any firing rate wanted,andthe best high frequency excitation 
waves mix.DRSSTC,VTTC,etc.
The only limiting thing is not to exceed 100 000 V terminal potential.
Supposing a normal atmosphere enviroment is that possible?
I know that in no circumstance 50 kV can close 5' wide gap unless directly 
conducting path is formed somehow,or a
strong external ionization occurs ,like exposure to a flame,extremely powerful 
lasers,but Tesla transformers are the 
champs of 'spark pumping' and I was wondering what could be done with 100 kV.
Thanks for  your answers and explanations.
 
Dex
