Hydrogen Car

I think Obama mentioned hydrogen cars in his Lansing speech. Here is a review (a bit dated) of BMW's hydrogen car. Funny as well as informative.

BMW Hydrogen 7 - A Sedan Fueled by the Future - Review - NYTimes.com:

"It seems that BMW drew the Port Authority’s attention when it began pumping liquid hydrogen into its small test fleet of dual-fuel sedans in Port Jersey, not far from the docks where BMWs disembark after their voyage from Germany. And historically speaking, it’s fair to say that the last hydrogen-dependent German flagship that docked in New Jersey left a lasting impression.

So while BMW designed the Hydrogen 7 to be as explosion-resistant as any gasoline car, memories of the Hindenburg zeppelin cause misunderstandings among consumers and bureaucrats, a company spokesman acknowledged.

As with hydrogen cars from Ford, General Motors, Honda and others, showcasing hydrogen’s carbon-free potential is the BMW’s reason for being. But unlike far-costlier fuel-cell cars — which generate electricity through a chemical reaction of gaseous hydrogen and oxygen — the BMW runs on either liquid hydrogen or gasoline in a familiar internal-combustion engine."
