Re: [TCML] Ozone Generation

I have lingering pet odors in a room that I need to eliminate and

occurred to me that I might be able to use my large DRSTC to produce
ozone in large quantities. For this application I assume that I need
lots of little sparks rather than big power arcs so I'm looking for
suggestions from the list. My idea was to place a large piece of
copper window screen on top of the toroid extending beyond the radius
of the toroid, or to eliminate the toroid altogether and just use the
screen. Any ideas?

Dave, using a large DRSTC for an ozone generator would not be very
practical. You can make a very effective ozone generator with a neon
sign transformer, some window pane glass , aluminum foil and a small
fan. Basically what you want to do is make a glass plate capacitor but
leave about an 1/8 inch gap between one of the metal plates and the
glass so air can get through and hook up the neon sign transformer to
it. Another simple approach would be to make a wine bottle
capacitor and use window screen as the outer plate instead of tin foil.
The professional ozone generators use glass tubes with foil around
the outside of the tube and a thin wire going though the center of the
tube . A high voltage is applied between outer foil and the inner wire
and oxygen or air is blown though the tube.
Back in the day (1950s-1960s) it was very common practice to use
glass plate capacitors when building a Tesla coil and the capacitor
would usually produce more ozone than the discharge from the secondary
coil.
I could see building something like this just as an experiment to see
what ozone smells like but I don't think I would want to have it running
in my house all the time. An electronic air cleaner might be a better
approach.
