"or if 50 percent of energy generated goes back into re-generation............its water ...good cheap clean water."

IF it were 50 percent of the energy generated! It is really right now, put in 100 energy units and get back 40 to 70 energy units....it is a net loss process using electrolysis.

Give me a dollar and I will give you back 50 cents...see how long you play that game!
