sorry, another newbie question.
what's the minimum voltage to set between plates to get good electrolysis? I'm guessing ~12/7 V since 7 cells is mentioned quite often.
my question is, wouldn't higher voltage help migrate H's to the negative terminal and O's migrate to the positive terminal?
do you produce more gas per sec with higher voltage?
what other downside is there besides wasting power which ends up heating the water?
