If there is a "Bias Voltage" on the plates on a floated-plate cell
or the concentric cylinders of the Joe Cell the OH- on one side
can lose it's electron and come off as a gas, almost at the
same time the H+ or H3O+ gets an electron from the other side
of the same floated-plate and comes off as H gas too.
Cathode - +- +- +- + Anode

The Joe Cell has about a half square meter of wetted electrode area.
Giving off "Free O, O2, OH, and H and H2 gas?
