Re: Wind vs Spark Length.

Yes, wind can really affect your coil's performance.
I learned this firsthand during a demonstration at Richard Hull's this year
with my PlasmaSonic Stereo SSTC system.
There was only the slightest of breeze outside, but when I was running the
coils, the audio was severely degraded and sounded
absolutely horrible.  I played with it for awhile and then realized this
slight breeze (which you could barely perceive) was moving the output
discharge
just enough to distort the audio reproduction.  I later moved the coils
inside, and it worked perfectly.

Also, with my other coils, if it is windy outside, the arcs can be limited
and extinquished by the wind as well before they have a chance to meet
maximize distance.
