Solar Thermal Fashion

The future's so bright, I gotta wear shades

—Timbuk 3

 

Courtney peers into one of the heliostats of the BrightSource solar thermal facility in the Negev Desert of Israel.

 

Each of these flat mirrors aims the sun at a boiler tower, heating it to 1000°F to drive a steam generator, feeding electricity to the grid.

 

BrightSource believes that this will be the least expensive source of renewable energy and cost competitive with fossil fuels.

 

I just calculated that for their current projects in the U.S. alone, they will install 2 million of these mirrors… which will power 1.4 million homes… about 1.4 mirrors per home.
