One of the three Luz International solar energy complexes in the Mojave Desert, California. Together these sites, which cover 1000 acres, generate 275 megawatts of electricity, 90% of the world's total grid-connected solar energy production. This installation, located at Kramer Junction, has an array of 650,000 computer- controlled parabolic mirrors which track the sun across the sky, focusing it's light onto tubes containing a synthetic oil. The oil, which is thus super-heated to 391 degrees Centigrade, is used to boil water for steam turbine generators in one of five power plants.
