Hi Billy, > Hello group, thanks for such an informative and helpful list. > I am currently making a CS generator in the hope that it will > address problems with Psoriasis, so any help on that subject would > be appreciated. I'm not sure if it would do much, but you can search the archives for more information. Just enter a word of three letters or more in the search box at http://escribe.com/health/thesilverlist/index.html There is a wealth of information avaliable on just about anything you can imagine. > I have several questions that the group gurus should be able to > help me with. > 1) Reversing the polarity at, say 60 second intervals.

Polarity reversal has been studied extensively. The problem is it increases the chance silver ions, Ag+, will combine with hydroxyl ions, OH-, that are concentrated near the electrodes. This will reduce the ionic ppm, which many oldtimers have stated actually does the work. From my own experience with the Shingles virus, I agree. Steve Young posted a comparison on June 29, 2000, that showed a 48% drop using switching periods of 17 seconds and one minute: http://escribe.com/health/thesilverlist/m23530.html > 2) I have an output of ~28-30 volts, current limited. What is the > ideal maximum current to limit the output to? It depends on the current density. Above 1 mA or so, the concentration of ions in the Nernst diffusion layer is strong enough to produce lots of black silver oxide and hydroxide. This coats the electrodes and the side of the glass, and limits the maximum ionic ppm to about 10 or so. Ken's Silverpuppy runs at 615 uA/sq.in and gives good results. I use 100 uA/sq.in. or less, and sometimes get a trace of oxide on the electrodes. With good quality dw, I can get above 20 ppm calculated easily. Also, you need to minimize any sharp corners, such as at the cut end of the rod. Ken uses a U-shape that gives two parallel electrodes connected at the bottom. I took his idea and formed a W-shape to give more wetted area and reduce the current density. The current is still concentrated a bit more at the bent ends, which gives a local hot spot for the formation of oxides. I then went to spiral electrodes which have gradual bends for the risers. This improved the performance, so I can get well above 20 ppm calculated before the cs starts showing a tint. There is a slight buildup of gray silver on the cathode, but it is minor. The process is very sensitive to slight changes in ion concentration at the end. Just one or two ppm difference is all it takes to make the difference between clear cs and cs that starts showing a slight yellow tint. If you run at high current to reduce the brew time, the cell resistance will produce a voltage that is higher than the 37V limit of the typical regulators, such as LM117 and LM134. I posted an ascii design earlier for a current regulator that goes to 160V, but it's not for people who are not technically skilled and don't know how to keep from electrocuting themself. It is very similar to a design Steve Young posted a long time ago http://escribe.com/health/thesilverlist/m29691.html But his schematic was lost when the post was archived. > 3) I have read where replacing one electrode with stainless steel > rod in place of the silver gives good results. Comments yes/no > please. Several people have commented that silver ions have a special affinity for stainless steel. I use silver for both electrodes so I can switch them on alternate batches and equalize the wear. > 4) What is the optimum distance apart for the rods? Not too critical. Most people run about 1 to 1.5 inches. It helps to keep the distance constant to minimize hot spots, so you need a sturdy mounting arrangement. I bolt mine to a plastic lid. > Hey, this time last week I'd not even heard of CS! So please treat > me gently ) Welcome to the list - you're going to find a lot of new friends! > Regards, > Billy.
