: 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.
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,
