Subject: Hi All
Hello, my name is Cabbott Sanders.... I am a fairly inexperienced Tesla coiler,
with a lot of extra cash and a hellava big project on my hands... to produce ball
lightning using an out-of-phase dual tesla coil arrangment. This has been done
before, but didnt recieve much recognition and was dropped immediately after these
two physicists made up some theory about how ball lightning works. My website
still needs to be updated, but it details my design work.
I am currently constructing two seperate tesla coils, both running off of the same
cap/power supply.. (Has this been done by anyone recently?) but with one
catch....(hehe) listen carefully:
The primary frequency will be constant with both primaries... (both primaries will
be identical, hooked in series)
however, the secondaries will be much different.
one will resonate at double the frequency as its primary, and the other will
resonate at 3 times the frequency of the primary. the primaries (hooked in
series) will act as a hammer to each coil, making each one ring at its own
specific frequency. Why you may ask? well because... each coil will at first be
in sync... but as they ring, suddenly they become completely 180 degress out of
phase!! this sudden rise in potential gives way to a sudden direct discharge
between coils. this is the secret to artificial ball lightning generation, as
proven by Corumn and Corumn in 1991. (I have references) Now there is a complex
theory behind all this, and that is what i am about trying to explain and prove
with my setup. Basically, what it takes to make ball lightning, is to achieve the
MAXIMUM rise in current density within a space. Yes, there is a maximum rate that
a current flowing from point a to b can change. they've done this experiment
dozens of times, in countless universities. its called the "z-pinch" experiment.
However, they seem to think they have reached the maximum current density in the
universe.... when actually they have just reached the maximum change in current
density. what happens when a plasma reaches this limit? ball lightning!
okay... back to earth....
I've been collecting parts for the full scale model which will run at 15 kva full
Here is some of the things i've recently purchased (they are sitting back at my
lab and I'm all excited):
15 KVA POLE PIG----(T&R electric, S.D., $470 delivered)
.161 uF 45 KV MAXWELL CAP (surplus sales of nebraska, $463 delivered)
my attempts at a full scale project of this magnatude has led to some questions i
was hoping someone might be familiar. Here they are:
My secondaries are going to be 84" high (24" wide) and 54" high (18" wide). I am
using some large cardboard tubing (used to pour concrete poles for bridges) for my
coil forms. (I know, i gotta seal them up first). The only wire i could find
around here for such monsters is some SQUARE MIL .102" motor wire. (equivelent to
11 guage sort of) now, this "square mil wire" comes in a 254 lb roll... for $700..
wire in these sizes only comes in square mil... which i can see would wrap very
nicely.. and come out completely smooth and pretty.
Has anyone ever used square mil wire for tesla coils?
I would think that it would work great because it would result in a completely
smooth surface. after varnishing, i expect it to work great. The wire has a
rectangular cross section. It is meant for layering better on huge motors, so why
not tesla coils? The actual edges are slightly rounded.. its got some 5 kv mylar
high voltage insulation on it. Good stuff. I plan to pick the wire up this week.
Well, thats enough for now, feedback from anyone is welcome and will be replied to
