the immediate key word is pure water
tap water is not pure, it has flouride/flourine & other bacteria killers in it
the oceans salt water is not useable either
i imagine one needs to distill the fuel source water to be electrolited into its H2O parts
with pure water a limited resource, it is more needed for living organisms consumption rather than fuel...unless your willing to pay $5 a gallon for
water instead of $3 a gallon for gas (which one cannot drink)
