I saw that quip about raising gas taxes (ostensibly to fund alternative fuel research) and it caught my attention too. Power companies and energy "suppliers" are performing research on their own, as they know that oil won't last forever and they need to be ahead of the game.
Unfortunately, Pres. Bush continues to pound the podium for big government solutions to problems. I haven't heard too much about the Hydrogen Fuel project lately.
By raising taxes on fuel the US could lower its excessive CO2 exhausts while at the same time being able to provide funding for research in alternative fuel. The oil companies are so blinded by quarterly earnings reports that they can't see around the corner.
The US has to do its part, it can't leave it to the rest of the world alone.
