According to the website a hydrogen car will get approx 60 miles per gallon and will produce .15 kg of water for each mile driven.

While I'm not a strong proponent global warming I am certain that the byproduct of water will be easier for the earth to absorb than half burned hydrocarbons on gas exhaust.

If you are producing your H2 by disassociating hydrogen and oxygen from water... then oxidizing the H2 (in fuel cells) merely returns the same amount of water you had to start with: no net increase.

(Anyway, *lots* 'O water in the world.)

All that water vapor "might" alter the environment slightly.

Cities, because of the amount of blacktop and number of air conditioners releasing heat into the atmosphere already have a measurable impact on the immediate climate.

The water vapor impact would be far less damaging than current tailpipe emmissions. The pressing concern is how to generate the electricity needed to produce the hydrogen. Burning coal wouldn't be the best idea...
