Joseph-- There's an ion-permeable membrane (cheap) and voltage-correcting circuitry, but the expense is in the electrodes. The anode isn't a problem--stainless would actually work (it could even be nickel)--but the cathode must not degrade in acid, nor colloidalize electrochemically. They usually employ a titanium substrate, catalytically protected by platinum plating. Having these made can cost hundreds. At the tmie I left off researching it, I was looking into other candidates including carbon, new iridium compounds, and especially *conductive polymers*.
I've a friend who really believes in these devices, and claims there are ways to measure the charge; a good unit is supposed to yield -900mV. --Russ ----- Original Message ----- From: Joseph Fritz <sil...@chaosrealms.com> To: <silver-list@eskimo.com> Sent: Sunday, February 24, 2002 9:24 PM Subject: CS>charged water > I was recently looking into ozone air purification devices and on one site > I saw a device that made alkaline/acid water > it sounded interesting but I don't want to spend several hundred dollars > for one I was wondering if anyone knew how > to make one? from the description it sounded as if it was just a simple > electrolysis unit with water from one electrode > producing alkaline water and the other producing acidic.
