Hi all, I'd appreciate if those of you who feel qualified would check my math and offer your comments on what I'm proposing to build. Ole Bob? Trem? Ken? Anybody?
I'm aiming for a design that will... 1) Make a quart (liter) of CS overnight, unattended, 2) Eliminate all mechanical or thermal stirring, 3) Avoid build-up on the electrodes. I've attached a simple sketch of the electrode arrangement I'm thinking about. For the anode I'll drill a hole in the edge of a 1 oz .999 silver coin and hang it from a small hook bent in the end of a piece of 12 ga silver wire, then crimped. The wire will be insulated with spaghetti tubing and the immediate area of the hook painted with clear nail polish or the like to avoid non- uniformities in the electric field and to keep the wire from eroding. I'm thinking about 2 cathodes, one on each side of the coin, made from more 12 ga silver wire with all but the bottom 2 or 3 mm of their length also covered by insulation. The exposed portion of each cathode would be a bit more than the radius of the coin away from each side and alligned approximately with the center of the coin. Anode surface area: diameter: 39 mm face area: 2389 mm^2 (includes both sides) thickness: 2 mm edge area: 245 mm^2 total area: 2634 mm^2 Electrical parameters: max cell voltage: 9V max cell current: .75 ma (current limited) max current density: 0.284 ua/mm2 or 183 ua/sq.in. Faraday calculations predict approximately 3 ppm per hour into a liter of water. What will be the quality or character of the CS? What are the consequences of the low current density, the ratio of anode to cathode surface area, and the lack of stirring? Thoughts and suggestions? Thanks, Mike D.
