Solar Thermal with Molten Salt?

Now this seems like a pretty cool idea in renewable energy. I was recently doing some research on what solar thermal energy companies are out there and came across this article. The idea of storing energy in molten salt kind of sounds like what a Bond villain would do.

The technology solves the problem of solar power’s intermittent
power-generation ability by storing energy in the form of heat in molten salt.
Mirrors reflect and concentrate sunlight onto a central receiver that uses
Rocketdyne’s heat transfer technology, which was originally developed for use in
liquid-fuel rockets. The extremely hot salt is then piped through another heat
exchanger, making steam that in turn powers traditional steam turbines.

This Earth2Tech site is great for reading about new green initiatives and how to make money from them. After I did well in ESLR a while back I watched as these stocks cooled down a bit and and are offering a great reentry point. I really like solar's future if Obama gets in there as well.
