Robert,

Thanks for the nice comments on my work.  I guess there's a "danger"
that
some of my findings will apply to only my coil, rather than be
universally
applicable; there are so many parameters and some are hard to control
for --
but gotta try.

Your Coronatron should be quite a sight when you get it powered to the
max at
15kW.  Interesting about the dielectric "smoking" and the "no nervous
system
sensation at all."
 
Regards, 
John Freau
