Jules Verne, in his 1874 novel The Mysterious Island, described hydrogen as an "inexhaustible source of heat and light." A little over 130 years later, BMW is testing the theory with an innovative internal combustion engine that burns the lightest element much like gasoline, only cleaner.

Wired News was invited to test-drive one of BMW's new Hydrogen 7 automobiles recently. It proved a serious step forward in using hydrogen as a potential energy source for cars, while showing defects that make the concept a clear work in progress.

BMW is the only major carmaker to bring a car with a hydrogen-combustion engine beyond the prototype stage.

The automaker's approach is markedly different than the more familiar concept of hydrogen-powered fuel cells, where energy is stored before it is converted into electricity. By contrast, BMW's Hydrogen 7 is powered by pumping hydrogen into a combustion engine and igniting it. The engine can burn both hydrogen and gasoline, and switches between the two at the flick of a switch.
