Anybody have a better memory than me? >sol Hi sol, As far as I recall, HVAC can make various nitrous oxides, some of which are toxic. I'm not sure if any nitrates are generated, which would be needed for nitric acid, which would be needed to make silver nitrate. We would need a real good chemist to sort this out, but I think it's pretty safe to say nobody uses HVAC for homemade cs any more. The ion concentration is too low - maybe less than 3 nines. Everyone I know who was using abandoned it long ago. One company may still use a special HVAC generator where the electrode is above the surface of the water and forms an electric arc. Frank analyzed their product and posted the results on his web site. I recall it makes about 20ppm, but I don't think Frank measures any nitrogen byproducts. I have the patent around somewhere but can't locate it at the moment. One thing I remember clearly is the patent stated the operator had to continuously adjust the spacing of the rods, and that it was fairly difficult to see the small arc. This means there would be large variations in product quality as the operator became fatigued. This seems like such a waste of effort when we can make equal or better ion concentration with LVDC, with no risk of unwanted nitrogen products. I still have two flat silver electrodes Ole Bob gave me to do comparison tests with 12 ga wire. He had used them for HVAC production, and you can see etching along the water line where the high voltage caused some arcing. I was thinking of firing them up this weekend to see if there was any change in performance with my new conductance plotting process, but it looks like the ozone machine will burn up all the available time.
