Re: Tesla Coil RF interference (humidity)

David,

Yes, I have noticed the same consistency in arc
lenghth over different heat and humidity levels.
If there is an effect on tesla coils, it is one that
is difficult to measure, and certainly not noticable
with the naked eye.  So as far as the effect of
humidity on the arcs we love to see, I would say
almost significant.
