Subject: Re: Yet another CuCl Regeneration Scheme

Yes - Ozone generation converts the oxygen in the air to ozone. Since oxygen is O2 and ozone is O3, and highly reactive, (it wants to revert back to O2 and O )it would seem to me that it would be more efficient.
Generating ozone is super simple, you just need a high voltage transformer (like a neon sign transformer), and a glass tube or jar with foil or screen inside and out. High voltage is applied to the two screens, and the resulting corona produces ozone - lots of it. It does not make any more oxygen than was already in the air (aprox 21%), but the resulting highly reactive ozone might speed up the regen process.
I have no idea if it will be more efficient or not, just another idea in a long series of various ideas on regeneration.

For the faint of heart, it does use high voltage, and could hurt if your are not careful.

Do a google search on ozone generator plans - - lots of "pot-head doper" websites out there with plans- they use ozone to help grow their dope.
