To me, the irksome aspect of brewing CS is the degradation of electrode surface area over time. At my request last year, Walter Cooke graciously developed a circuit that cuts off when an adjustable electrolyte conductivity is reached, but without means of monitoring wire dia., this still leaves electrode area out of the equation. (I suppose that even "current controlled" units like Silvergen merely assume this crucial variable!) Of course, one could measure the dia. with a micrometer and adjust the cutoff V accordingly, but is would seem that the ultimate CS gen still remains in the realm of Socratic "forms."
A few mos. ago, I hypothesized that this problem could be solved using flat electrodes; their disproportionate side-to-edge ratio migth remain constant as the electrode degraded. However, someone replied that flat bar eventually assumes a "V" shape due to an "edge effect." Therefore, A QUESTION TO ALL YOU WHO USE SILVER COINS: DOES THE ANODE REMAIN ROUND OVER ITS LIFESPAN on their way to becoming a piece of silver foil? Thanks. --Russ
