Re: [TCML] 5" Sparks - Approx 35 watts input power: Tesla was correct!
I understand what you're saying. What about the low power TC contest that
Gary Lau set up?
I think those coils were limited to about 50 watts or so? Some had some
shunts removed from
the small transformers, some didn't. I forget all the details but I think
someone got about
13" sparks. I'm not sure of the exact power they were using to achieve
that. Most of the
coils gave at least 6" sparks I think. I think the contest is still set up
at Gary's website.
Most of the coils were not made in the old styles from Tesla's day however.
some of the things that were discovered during that contest could be applied
an old style coil. I think of the keys was to use a rather over-sized
toroid, which would
not be in keeping with the old style appearance however.

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...?
