Electric cars never have been and most likely never will be practical, or economical. Hydrogen power will most likely be the fuel cell "of the future" because its just as easy to refill and time efficient as gasoline and costs about the same. The volt was a huge blunder on gms part and a lot of money wasted that could have gone into the camaro or Corvette or future projects.
I disagree with the comment about lack of infrastructure for hydrogen powered cars. How hard could it be to convert old gas stations into hydrogen stations? Honda already has a working hydrogen powered car so while it does bot have the 100 year history of the combustion engine, its hardly in its infancy.
Not quite sure how credible this website is but its interesting to say the least. Note the article is from 2009.
