And it Exhales Hydrogen - As in Fuel Cell Hydrogen
What the neo-con goons at the Heritage Foundation and Accuracy in Media forget is that radical change isn't bad unless you're heavily invested in the status quo. The reason they argue so ardently against global warming is that confronting the problem threatens the ample revenue streams of the wealthy who just happen to fund their work.
But imagine slashing greenhouse gas emissions in twenty years, or even ten. Better yet, by turning the energy market on its head political equilibrium will weaken the strangle hold that international bullies like the Saud family, Vladimir Putin, Hugo Chavez, etc. has on all of the industrial and industrializing world.
What technology could offer such short term results?
Modular pebble bed nuclear reactors. Rather than explaining their inherent safety and adaptability, check out this Wired article. 
Watch dog groups convulse at the mention of nuclear power and wax rhapsodic about solar, wind, etc.
Those technologies are not going to replace fossil fuel in the next fifty years. We're all hopeful, but we've been hopeful for over 30 years.
Environmentally these reactors are so promising that even MIT is enthusiastic.
You've heard of Shell and Exxon: ever heard of PBMR? The old order gives way to new?
This is the energy shift that will slowly decrease global petroleum demand. Even better, if energy independence is a worry, the US has enormous uranium reserves.
The greenies can fear what they don't understand, the conservatives can deny the winds of change are blowing around the world, but rational people embrace workable technologies.
The Chinese and South Africans lead the research but if safety is inherent in the design, it's time for American ingenuity to step up to the plate.
Oh yeah. Detroit is slowing its fuel cell experimentation because it sees no reliable way to generate hydrogen cheaply. The research is ongoing (see pages vi and vii), but apparently modular pebble bed reactors would be efficient making hydrogen even if that's all they were used for!
