I went over our 12 plate (~ 1.0 cm spacing) with my cohort/lackey with a starting voltage of "about 9 volts at 1.6 ma on the rechargeable power unit there were small bubbles on the water-plastic interface near the anode plate too. The rechargeable dc supply was brought up to ~ 13 vdc and the current maxed at less than 2.0 ma for a day or so until baking soda was added to increase it to about 19 ma. Adding borax the next day increased the current to almost an ampere.
