California opens one of the world’s largest solar projects

Less than a hundred miles from the rim of the Hoover Dam, just outside of Las Vegas at the edge of dusty San Bernardino County, sits a symbol of how the sun will some day provide copious amounts of electricity for entire cities. This is Ivanpah, the world’s largest operating solar farm, which uses 347,000 mirrors and three huge 450-foot towers to harness the sun’s heat to generate electricity.
