Recently, I had a remarkable flight from San Francisco to Dallas. It started out with mostly clouds and a few semi-interesting images (which I will post another time), but as we came out across Nevada, then on to Utah, Arizona, and New Mexico, the clouds cleared and amazing things began to grab my eyes. This was the first, gleaming in through the window of the plane to yank my attention up from my work: the
Crescent Dunes solar plant, a kilometers-wide installation in the middle of the Nevada desert. All these circles of mirrors focus sunlight onto a tower in the middle, filled with liquid sodium, and able to generate more than 100 megawatts of power.
