To get how much water it takes to make all this hydrogen gas, we have to go back to chemistry and the Molar balance. For every gram of hydrogen gas to be produced through electrolysis of water (no matter how fast,) 9 grams of water has to break down just to generate the hydrogen gas, and since water has the density of 1cc per gram, feeding an appetite of 6.07 grams of hydrogen gas per minute will require 54.6cc of water to be electrolyzed per minute. (This is slightly less than the 63cc of water per minute I previously calculated.) If your car drank this much gasoline at idle, you'd have a different hobby.
I'd show you the calculations, but there aren't enough pages here in this section, so you're going to have to trust me, just like I said last time. -JC
