Re: Elementary Lecture
Hi folks,
I have done class demos in the past and when I get another coil going I
want to use it in my lecture also.
However, I have had the question of liability especially on a coil that
shoots off a foot or greater sparks.
The classrooms that I have been in are loaded with computers and I would
be affraid that a large coil would fry something or at least the
accusation might be there. I thought that if I were to do this and plan
it, I would request a more neutral location like the auditorium or
lunchroom. Any other comments on this would be appreciated.

That is an excellent question that I would love to see answered. An
even
better
twist is that I have noticed that after the arcs reach the 30 inch
range, they
don't seem to "care" as much about the ground rod and seem just as happy
reaching
out into space.
Brian Basura's coil doesn't even seem to like ground rods, even though
he is
producing healthy 4-5 ft arcs! Yes, I'm sure the rod and the bottom of
his
secondary were adequately grounded... Is there a scientific explanation
for
this
or is his coil just "confused"? hehehe
Anyone have any ideas on this one?
