Re: Ozone levels

Original poster: "Devon Ferns" <dferns@xxxxxxxxxxxx>

Thanks for everyone's inputs.  So the concensus seems that if
anything, I must have a pretty well ventilated room.

I had the idea of enclosing the coil inside a plexiglas case to
protect from electric shock to the viewers, but as well, I think
it would be enough to contain any gasses produced.

Any thoughts on this?  From what I can tell, it should still work the same.

Does a tesla coil need air to discharge?  I also thought of filling the
case with argon or some inert gas.  I also thought that this might
affect the amount of sparks produced because it probably wouldn't
be as conductive.

Devon.

Terry, Devon,

Actually, and I think this has been brought up before on this list,
smaller, or at least medium sized TCs can produce fairly copius
amounts of O3 that can qickly reach toxic levels in a small, poor-
ly ventillated room. As a matter of fact, I've actually experinced
less detectable O3 odor from firing a large, pig powered coil than
from the smaller NST driven systems. I think someone mentioned
before that the higher powered coils actually oxidize more nitrogen,
leaving less O2 available to form the O3 (ozone) radicals (or some-
thing like that) :^) This would be a good time for some of the more
chemically inclined individuals to interject.... ;^))
