SAE Congress '08: the problems of fuel cell commercialization {Autoblog Green}

Apr 20th 2008 2:38AM I'd like to make sure here that everyone knows that there are two types of Hydrogen vehicles. There are the Fuel Cell type which are really a battery replacement for an electric car, and then there is say the BMW Hydrogen 7 which is an internal combustion engine running hydrogen. The later must be excluded from this article and discussion as powering a car this way (BMW) is on a whole other level, and a very intelligent level at that. I hope people here and the writers of this article will grasp this understanding.
