It is irrelevant how many joules of energy one can extract from water (even disregarding the fact that this quantity is virtually uninterpretable by the average person). The fact is, the conversion process is extremely inefficient in the current state-of-the-art, especially on-board an automobile. Maybe someday we will drive extremely efficient fuel cell cars, but in the near future, the alternative tech that is the most promising is electric, Exxon Mobile.
