@contrex,
electrolysis is , perhaps, the most inefficient way of releasing hydrogen . A new process which was developed in the late 1990's is a bioreactor in which an algae mass are deprived of molecular sulfur in their metabolitic cycles. When S is deprived, the algae switch from O2 production to H2 production. Its presently a bit hazy as to
1the energy lost in adsobing S
2The other metabolic byproducts
3The life cycle cost of a production of a given H2 volume
Still, we all unerstand that H2 is a useable fuel, the "free energy" crap is easily debunked is one were, saay, given 10MM bucks to make and sell H2 gas as a fuel. Keeping track of all life cycle costs would show that, within a span of time, youd go broke if H2 was comparable to gasoline in cost. H2 Would have to have a much higher market cost.
