"I can't believe you're getting excited by mere words from the mouth of Bush. Don't you know better by now? In his 2003 SOTU, Bush talked up hydrogen-powered cars, proposing a total of $1.7 billion over the following five years to develop hydrogen-powered fuel cells, hydrogen infrastructure and advanced automotive technologies. If he wants to lend some substance to the platitude you quoted about breaking our addiction to oil through technology, he should bring us up-to-date on just what that initiative has accomplished in the past three years.

I haven't heard anything about it of late. I have, however, heard that Exxon is reaping the largest profits ever earned by an American company. I wonder how much of that money they're plowing into R&D on hydrogen power."

Yeah, what did happen to the hydrogen car initiative?
