Aloha,
This cell consists of 7 sets of 304 ss, 24" long. Outside tube is 1 1/4" outside with 1/16" thick wall, inside is 1" with 1/8" thick walls. Inner tubes centers are sealed with plastic plugs gooped in place. Outer tubes exteriors are sealed to container walls with plastic and goop.
Water in cell is pumped thorough by a 2 amp SW fuel pump, and only flows thorough the ss tube electrolisis surface area.
Output volume currently untested. A second container holds the water as a reservoir.
