Japan auto firms rev up efforts for hydrogen cars

Imagine a car that can be refuelled in minutes but emits only water. Sounds like science fiction? In fact it already exists — Hollywood star Jamie Lee Curtis has one. So does Honda president Takanobu Ito. Yet while some see them as the ultimate environmentally-friendly automobiles, the high production cost means that affordable hydrogen-powered fuel-cell cars are still more of a dream than reality.

Manufacturers such as Honda, however, are making a renewed push behind the vehicles, which run on electricity generated by a reaction between hydrogen and oxygen, belching out nothing more harmful than water vapour.
