I've built ozone facilities for both water (150 million gallons per day) and waste water (60 MGD). I've always heard you could smell it during lightning storms, but have never noticed it, except for around copiers that need their filters replaced, and Tesla coils.

Hmm, interesting but methinks that smell is likely ozone. I have also noticed that same odor around active photostatic copiers as well as "ozone" air purifiers. And I have smelt a sharp, but somewhat different than "ozone" odor, in my garage after an extended run of my high powered jacob's ladder display and these noxious fumes also eventually lead to coughing and asthma like symptoms with prolonged exposure in a poorly vetillated garage. I would assume "that" odor to more likely be the NOx compunds. I'm thinking list member Adam, aka "yurtle turtle's" input may prove of value to this discussion, as I understand that he works with commercial O3 generators designed to purify drinking water for a public utility. Stands to reason that he would really know what O3 smells like :-)
