Gemasolar Thermasolar Plant, 37.560755°, –5.331908° This image captures the Gemasolar Thermosolar Plant in Seville, Spain. The solar concentrator contains 2,650 heliostat mirrors that focus the sun’s thermal energy to heat molten salt flowing through a 140-metre-tall (460-foot) central tower. The molten salt then circulates from the tower to a storage tank, where it is used to produce steam and generate electricity. In total, the facility displaces approximately 30,000 tonnes of carbon dioxide emissions every year.
