So said GM CEO Rick Wagoner last night at his <a href="http://www.topspeed.com/cars/car-news/-rick-wagoner-speaks-about-the-convergence-of-electronic-and-automotive-technologies-at-ces-ar50234.html" target="_blank">keynote address</a>, the first such speech delivered by a Detroit chief at CES. To prove his point, he unveiled its new hydrogen-powered Cadillac Provoq--certainly one of the biggest pieces of hardware to debut in Vegas this week. Good thing there are so many hydrogen refueling stations in this country! Oh, wait ... <br><p> Like the <a href="http://www.newsweek.com/id/81580">Chevy Volt</a>, the Provoq would run on GM's new <a href="http://www.autobloggreen.com/2007/01/07/detroit-auto-show-general-motors-e-flex-platform/" target="_blank">"E-Flex" architecture</a>. It won't be ready for several years, but the Provoq, with its fuel cell stacks and lithium ion battery pack, is certainly an exciting prospect as fuel prices hover at the $100-per-barrel mark. It could also be the first zero-emission luxury car, running up to about 100 mph and emitting only water vapor. And yet. What Wagoner neglected to mention is that hydrogen fuel is made by reforming natural gas, a process which releases CO². Not so efficient ... or, for that matter, green. </p><img src="http://blog.newsweek.com/aggbug.aspx?PostID=122271" width="1" height="1">The SceneThe SkepticGadgetsBlog: The Revolution Will Not Be Digitized
