For those of you considerating the purchase of an ozone generator to make water: the best writeup I've seen so far can be found at ozonelab.com/faq/faq024.htm especially if you plan on using ozonated water to cure a disease, etc...there's an awful lot of misinformation out there. Also, MEDICAL ozone generators do not use ambient air (80% nitrogen) as an oxygen input because (I think) the nitrogen becomes nitrous oxide which when combined with water, becomes nitric acid. This possibility would make me very nervous. Hank
