: Thank you very much Bert.
: If possible, I would appreciate if you could get hold of Tesla's cold
: plasma ozonator plans. Apparently it's secret lies in a certain mixture of
: rare gasses inside a neon tube that produces ozone without any traces of
: nitrous oxide for a long period of time. The comercial ones are very
: expensive, but neon tubes are not that hard to make.
: Best regards.
: Hi Pedro,
: Tesla's patent for an ozone geenrator used a high frequency transformer to
: generate corona between two electrodes. The electrodes were simply spaced
: far enough apart so that they did not actually spark over. The patent is
: US Patent number 568177, dated September 22, 1896. You can see a PDF copy
: on Bart Anderson's site:
: A lot has been learned about efficient ozone production since Tesla's
: time. If you want to use neon tubes, you can use the following approach.
: BTW, there is nothing magical about using neon tubes - virtually any
: rarified gas will work, ao you can use a pair of tubes with neon, argon,
: mercury vapor, etc.
: All are fine - even fluorescent lamps should work. The tubes are placed in
: parallel with each other and a HV AC source (typically a neon sign
: transformer) is connected to across the electrodes on the near ends of the
: tubes. The far ends are NOT electrically connected and are insulated to
: prevent them from arcing to one another or anything else. Electricity
: flows through the rarefied gases in the tubes, and is then
: "capacitively" coupled through the glass and through the air
: space (as corona) between the tubes. This is just another form of a
: dielectric barrier discharge. As long as there is no actual arcing or
: sparking, ozone will be produced with little nitrogen oxides.
: Good luck and play safely,
