Comment on If we can use hydrogen to power electric motors, why can’t we use water to run a car?

“Hydrogen powered” generally means burning hydrogen in oxygen to make water: 2(HH) + OO -> 2(HHO). To run a car on water as you say is a lot like trying to make a fire out of ash, rather than wood. You can’t burn the ash because it has already been burned.
