From what I've read hydrogen cells are the way to go (no more dependancy). Now it seems like two major discoveries have added a boost to the technology: researchers discovered that hydrogen could be released from glucose molecules using cheap tin, aluminum, and nickel catalysts instead of expensive platinum; another researcher found that if you do use platinum, you don't need nearly as much as was once thought (they coated a metal with platinum and then used acid to remove most of the platinum--the platinum left behind was enough to do the job, while the platinum that was removed was recycled.

These are just the kind of advances that we need to eliminate our dependence on foreign oil.

There was a scare recently about the possibility of hydrogen cells hurting the ozone layer. Luckily, a clear-headed engineer said that it was all a question of engineering; in other words, if a leakage problem existed, you only had to engineer it away. This is the sort of thing that Alfred Nobel did with nitroglycerin when he added it to saw dust.
