Power Plant Panacea?

I was in my friend's bathroom the other day reading reading a Fortune magazine, when I stumbled across an interesting article on how to address the nation's growing electricity demands. The basic idea is a line of underground air-cooled nuclear power plants stretched across the country at 100 mile intervals. The plants would be interconnected with superconducting materials, and power could be shifted to wherever there was demand with very little loss. All the radioactive material could permanently be stored underground. One requirement of superconductors is that the material be kept at a very low temperature (not far from aboslute zero). This is where things get neat. The superconductor lines could be kept cool with liquid hydrogen that was produced by electrolyzing water (passing current through it). The electricity required for the electrolysis and liquefying the hydrogen could be obtained from the power plants. Furthermore, when the power lines emerge from the ground, the liquid hydrogen could be collected and used to power hydrogen vehicles. This could help solve the distribution problem facing hydrogen powered vehicles.

Clearly, there are many many issues to address before such a power grid could be implemented, but I thought it was an interesting idea to share.

P.S. It looks like I avenged my fantasy football beatings last year at the hands of Sam, 82-62.
