CS Maker for Emergencies >>> Dan Nave <na...@comcast.net> 11/15/2005 5:47:59 PM >>>
I did some experiments using two different kinds of tap water, one from St. Paul city water which I drink and which has a average amount of hardness for city water and Plymouth city water which is so hard I won't even use it to make tea because it turns black and has foamy scum floating on top... I put two clean copper wires in a styrofoam cup and attached them to a power supply with an ammeter in series. Then I filled the cup with the water. The distance between the electrodes was about 3" at the side of the cup but (est.) 1.5" near the bottom. Also tried it with the wires about .75" apart, similar to a 9V battery terminal spacing. St. Paul water current was 5ma at 3" at 9V. St. Paul water current was 8ma at .75" at 9V. St. Paul water current was 20ma at 3" at 30V. Plymouth water current was 10.6ma at 3" at 9V. Plymouth water current was 15ma at .75" at 9V. Plymouth water current was 43ma at 3" at 30V. Using the rule of thumb we would have .28ppm at 1ma for 1 minute in 1 cup of water. Therefore, for the above samples, assuming a 1 minute dwell time of the electrodes in the water, we would get the following equivalent concentrations of CS or silver compounds... St. Paul water current was 5ma at 3" at 9V. (1.4ppm) St. Paul water current was 8ma at .75" at 9V. (2.24ppm) St. Paul water current was 20ma at 3" at 30V. (5.6ppm) Plymouth water current was 10.6ma at 3" at 9V. (3.0ppm) Plymouth water current was 15ma at .75" at 9V. (4.2ppm) Plymouth water current was 43ma at 3" at 30V. (12.0ppm) These values are not excessive, although they are probably silver compounds rather than the EIS that we make with distilled water. However, I don't see any reason to use more than 9V for this type of unregulated system used with non-distilled water. (Higher voltages only make sense when using water with lower conduction characteristics, and also when using some type of current limiting.)

That is, 17ppm max in an hour (under these conditions). I assume that there is sufficient conduction to reach saturation at 1ma immediately. 17ppm divided by 60minutes = .28ppm per minute (approximately) .28ppm per minute times 3 minutes = .84ppm (approx) .28ppm per minute times 5 minutes = 1.4ppm (approx) -----Original Message----- From: Faith Saint Francis [mailto:faithstfran...@hotmail.com] Sent: Tuesday, February 20, 2007 6:54 AM To: silver-list@eskimo.com Subject: CS>One more question: the Quantity? Good Morning dear C S Fellows! Concerning our home-factory of C S: We are working on a stock of C S, in order not to have to say "no" to anybody in need. We've been on the time-span during which C S can be stocked, I remember it is rather long, if not cooled in the fridge, and that is okay. Question: How MUCH can one make in one shot, in other words: What is the greatest amount of water one can safely process, for one half hour's brew? (We use rods of 12 cm in length -that would be about 5 inches if I'm not mistaken- and 2 millimeter in diameter, with 30 volts/400 milliamps. Thanks again!
