cost of running a generator to produce electricity is 5 times that of electricity from a wall outlet and my figures to produce enough hydrogen to replace a gallon of gasoline, figuring that it takes 240 watts to produce a liter of hydrogen and that it takes 1352 liters or hydrogen to equal a gallon of gasoline and my electrical costs are $0.12 per KWH it would cost me $37.30 at home to produce enough hydrogen to replace a gallon of gasoline, or it would cost $186.50 if I was using my cars alternator to power a hydrogen generator, I've made hydrogen at home and I've made hydrogen using a small industrial fuel cell hydrogen generator and those figures look pretty accurate, that is why if you buy a bottle of hydrogen from a welding supply shop, it's extracted from natural gas, extracting it from water costs to much!
