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. -marcus- -- ----------------------------------------------------------------------------- "Opinions expressed above are not necessarily those of anyone in particular." `...but do YOU own a | INET: cygnus@udel.edu homemade 6ft Tesla?' | UUCP: {yourpick}!cfg!udel!cygnus
