Better hydrongen production compared to my other experimental electrode. Smaller tube is 1/4″x 4″ and bigger tube is 1/2″ grade 316 Stainless steel wall 1/32″ thick.
consumed 13vdc 1.6amp, container diameter= 3″ the disc rings holding the tube are 2″ dia.

will install this unit into my car and step up the voltage to 200vdc
