You forgot the worst part - transporting it.
Currently, hydrogen is transported in its liquid state, in semi-trucks. To a lot of people, that's an accident waiting to happen.
To the idealist, using solar-powered electrolysis <i>on-site at the dispersal pump</i> to separate hydrogen atoms from the oxygen in water is the answer. Solar power is the one source of energy we can afford to waste - there's more of it around every day than we could possibly capture and use in a year.
Otherwise - yes - it's a pipe dream. Do the physics - we start with water, end up with water, and in the meantime, we have to power a 2-ton vehicle down the highway. That means a shitload of energy must be input somewhere in that process. To make it feasible, that energy must be "pretty damned cheap".
Granted - we're far from getting there at the present level of technology - but wait 'till Texas oilmen start seeing a profit in fuel cells - the technology will take off real quick - just you wait and see.
