After seeing how dependent people are on oil and power companies the past few days, I think it would be a good thing if we started to decentralize our energy production a little. Have the grid as a backup, but use more solar, wind, hydro, geothermal, LNG, even nuclear to produce power where appropriate.
There are plenty of ideas and innovation in the clean power business, and I think it would be good if we had a wide range of different energy production and transportation types out there.

I would be in favor of giving the Los Alamos guys a grant of $300 million and the promise of $300 million more (McCain's idea) + some profits of the sale of these small nuclear batteries with the idea that they could develop this in 4 years if you throw enough physicists, chemists, and engineers at it. They did it once already in the New Mexico desert, they can do it again.
