This solar grid in the Mohave desert utilizes thousands of mirrors called heliostats to focus solar energy on a boiler, where water is vaporized at over 1,000 degrees to create steam to drive turbines. Think of it as a nuclear power plant, without the radioactive dangers or the giant cooling towers to clog up the skyline. Overall this system can produce 240,000 megawatts of renewable electricity a year. Pretty cool idea and it looks rather intimidating from the air.
