Hey! What's wrong with really big sparks? :-) :-)

...then again, I *am* very familiar with the behaviour of high-potential,
high-frequency electricity.

Building the little Tesla was fun, but 10" of corona just didn't satisfy
me, so I asked that exact question: How Can I Make Really Big Sparks?

I don't remember the reference now, but you can get a copy of Nikola Tesla's
New York lectures, printed circa 1920 (??)... and if you're really 
industrious, you can build some of his disruptive discharge coils right
from the original plans :-)

I'm working on a modified coil now. There's a general rule by which you can
judge the size of a coil's output discharge (how big of a gap the output
spark can jump): on a ridiculously dry and favourable day, a given coil's
discharge can exceed the length of the actual coil (secondary coil, of
course).

I've wrapped a 6' secondary for my second shot at it.

Only thing is, if I ever get the capacitor and spark-gap built, I'll have
to find a friend with a farm in the boonies of PA or something like that...
don't want the FCC breathing down my neck, especially after finding out
the radius of radio disruption the *little* coil produced. Sheesh...

...and I don't think I'd be too keen on coming into contact with the output
of the big one. That was one of the fun things about the little guy; you
could actually touch the output terminal (with a metal object in your hand,
of course) and draw a spark off of it. Makes for good classroom demonstrations.
