Guest: Joseph Romm.

In his State of the Union address last year, President Bush called for the development of hydrogen as an energy source. This morning on Focus we'll talk with former Department of Energy official Joseph Romm about whether hydrogen could be powering our world in the near future. Romm says he doubts that hydrogen-powered cars will become available anytime soon—but hydrogen fuel cells could power our homes and businesses. He'll also discuss his recent book, The Hype About Hydrogen.
