Well, I've almost been struck by lighting, and that makes ozone. I have an ozone generator, that makes ozone. I've shocked the crap out of my sister running around the carpeted house in slippers. Static shock makes ozone. Old tvs when turned out can make a lot of ozone. Lots of crap makes o3, and I suppose this is one of them. I know a flame in a microwave makes plasma, and I believe o3. I really don't know the physics, but I know what I smell.
