According to Bloomberg New Energy Finance, solar-based energy will provide power to 100 million households worldwide by 2020. A new development, SolarReserve’s concentrated solar plant, Sandstone, will be the largest utility-scale solar installation of its kind.
SolarReserve says Sandstone will use 100,000 mirrored heliostats. These giant mirrors will not only reflect but concentrate the sun’s rays onto ten towers containing a molten salt storage system. At over 1,000 degrees Fahrenheit, the molten salt boils water which drives a steam turbine that can power generators 24 hours a day.
