Seen here during its construction, the Crescent Dunes Solar Energy Project near Tonopah, Nevada, USA now powers approximately 75,000 homes during peak electricity periods. The facility uses 17,500 heliostat mirrors to collect and focus the sun’s thermal energy in order to heat molten salt flowing through a 160-metre-tall (525-foot) solar power tower at its centre. The molten salt then flows from the tower down to a storage tank, where it is used to produce steam and generate electricity. For a sense of scale, see the lower left corner which shows a commercial aeroplane flying over the complex. Photographed at an altitude of 600 km from outer space by Digital Globe.
