Thanks for the nice comments on my work. I guess there's a "danger"
some of my findings will apply to only my coil, rather than be
applicable; there are so many parameters and some are hard to control
but gotta try.
Your Coronatron should be quite a sight when you get it powered to the
15kW. Interesting about the dielectric "smoking" and the "no nervous
sensation at all."
