RE: [TCML] 5" Sparks - Approx 35 watts input power: Tesla was correct!

[Jeff Behary <electrotherapy@xxxxxxxxxxx>]

John,
My point of this was a while back when everyone was getting fed up with the "wireless transmission" posts.My argument was in general to try and recreate some of Tesla's work that is achievable - like anefficient table top coil as those Tesla made in the 1890s.  There was a lot of neat patents and conceptsthat came from that period, and all of them are "on topic" and relating to "Tesla Coil" construction.
 
The result was more or less a bombarding of posts regarding how authentic Tesla's statements were,suggesting the claims were exaggerated/etc.   Several people mentioned ignition or induction coils withthose efficiencies, which I agree are completely possible, but I am interested in Tesla Coils,resonant circuits with high efficiencies.  Something like we normally build, but low power.I know with your brilliant work in modern Tesla Coil circuitry that for sure these claims are easilyobtained if Tesla could do it with archaic technology.  I would love to see it though from someone,because I think it may offer some interesting designs and creativity.
Its an unusual request to group of people normally making huge sparks.  The 35 watts is irrelevant to me,
I was hoping just to see some responses of low power (less than 75 watts) and efficient Tesla Coils (4 - 6" sparks?) made by people on the list.  As much as there is a fine art in making huge sparks, I think thereis an equal opportunity of creativity in making smaller, more efficient machines too.  Surely something can belearned from it...?
