I knew that ozone attacks rubber, but it never occurred to me that all the
belts in my old VCR and cassette players fall apart. A couple "Pease
Porridge" columns in Electronic Design mentioned this effect, and many
people responded in the "mail from readers" to say that the same thing
happened to them too.

Yeah, the price is a ripoff and it's because O3 generators are a new-age
fad.
A genuine Tesla-type ozone generator is made of two metal plates
sandwiched between sheets of glass, then the glass-covered plates are then
held about 1mm apart. Connect the plates between a TC output and ground,
and the entire air volume in the narrow gap between the glass plates will
glow purple. (The glass prevents sparks while allowing plasma discharge.)
Crank the TC voltage down so you mostly create ozone and not oxides of
nitrogen. Add a little fan to pump air through the gap.
