Earth to Carol Lynn: That

Earth to Carol Lynn: That Honda car is powered by hydrogen not water. They say that the car is being introduced in Southern California in places where there are available hydrogen fueling stations. Yup, you have to fill up your car at a hydrogen fueling station. It doesn't run on water. Likewise, the BMW can be run on gas or hydrogen, and if you want to run it on hydrogen you need a hydrogen fueling station.

So where does the hydrogen for the fueling station come from? Well, no doubt it is made by splitting water into hydrogen and oxygen. The energy required to do this comes from burning coal or natural gas, or from nuclear power, or from hydro power, whatever the grid uses. Ultimately those hydrogen cars are powered by a conventional power plant.

The biggest beneficiaries of a switch to hydrogen cars will be the coal miners and the natural gas drillers.
