However, attempts to operate with equal area rods is turning out to be problematic. The last run using 0.9 sq. in. rods formed into a "J" to clear the bottom of a short glass seemed to hit a plateau at 1.228V - the voltage you mentioned was the ionization voltage of water. When I disturbed the system, the voltage would go below this voltage, then slowly rise to meet it. If I managed to get it above, it fell back to the same voltage. So maybe I accidentally made a cell that measures the ionization voltage:) I'm continuing with a larger glass and the same rods, but I changed the series resistor to 25k shortly after the start of a run. This produced an interesting oscillation of about 1V p-p in the cell voltage, indicating there seems to be a battery effect. I think a similar effect was observed by others in the archives. I won't clog up the list with the detailed measurements, but they are available to anyone who wants them. Reversing the applied voltage seems to help when the mist starts appearing around the cathode. But I'd like a system that didn't require constant obervation and fiddling. It might be necessary to add a small CMOS switch to reverse the polarity at some interval. This would be inexpensive, but it could be one more thing to go wrong. After this run, I'll try using a constant voltage source of 3V to 6V with a low value resistor and see what that does. Maybe the asymmetrical rod area is a key part of the process. Some of the runs produced the strongest cs I have ever made, and none of the solutions have turned yellow and plated out. So it seems this is well worth pursuing.
