FPL and solar-thermal energy

Isn't $80/barrel oil grand? Recently, Florida Power and Light announced that they would build a 300MW power plant (that's pretty big) somewhere in Florida. The system uses mirrors to boil water in pipes placed above the mirrors to generate steam. This steam is then stored, and used to drive turbines that generate electricity. The plant will be able to operate for up to 20 hours without sunlight, to help overcome cloudy days and nights.

The costs are competitive, and in some cases cheaper, than coal and natural gas plants. The company to build the plant is Ausra.

You will see a lot more of this.
