The eSolar plant in the Mojave Desert generates enough electricity to power 4,000 homesFrom Times Online:
On a dry, scrubby plain on the edge of the Mojave Desert north of Los Angeles, 24,000 mirrors track the Sun’s progress across a clear, blue sky. The neat ranks of heliostats and the computer algorithm that moves them make the Sierra SunTower plant a focal point for a novel type of power generation and a new wave of energy companies looking to turn the search for renewables into successful businesses.
Solar tower technology uses mirrors to reflect sunlight on to a thermal receiver atop a tower. The reflected sunlight boils water inside the receiver to create superheated steam at 440C (824F), which drives a turbine and generates electricity.
