Re: [TCML] 135ft arc 3ft sphere - Possible?

[Derek <tesla@xxxxxxxxxxxxxxxxxxxxxxxx>]

"You *can* get to close to 135 feet if you count all the little twists 
and turns and count tip of one spark across the middle and to the tip of 
a spark on the other side.  Bill Wysock's 13M gets there if you follow 
this somewhat unconventional measurement technique (of course he's 
running more power and has a much larger topload than a 3 foot ball) "

All Tesla coil sparks are actually of infinite length measured this way.

I beleive that a spark by it nature is fractal. The length around the 
outside of any fractal has infinite length if you look closely enough. 
(try measuring a coastline) Therefore if you count the circumference all 
of the twists and turns you get an infinite length.

Its amazing you ever get a strike !!

Just the way I look at it.  Wyatt
