I can't afford one of those generators (no local supplier). I was just going to use the basic 30V through two electrodes with a current limiter type. You think adding a stirrer is a good idea? If so, do you know what the stirrer should be made of and how fast/slow it should go?
I was under the impression that atomic silver was more beneficial than ionic (ionic being Ag+ ions). But yeah, maybe it's hype. Most of the Colloidal Silver made by these machines (silvergen etc.) will be ionic since it's all made by electrolysis regardless of who made the equipment. It did seem like a fun project, though, to try and make true atomic silver suspended in water at high concentrations. I bet there's a market for it.
