Aerial photo of the power block at the Crescent Dunes Solar concentrated solar power plant near Tonopah, Nevada: digital photograph

Photographer's note: "Aerial photograph of the power block of the Crescent Dunes Solar concentrated solar power plant near Tonopah, Nevada, USA, includes a 540 foot (165 meter) concrete tower topped by a black solar receiver, two large tanks for molten salt storage (one "cooler" at approximately 550°F / 288°C and one hot at approximately 1050°F / 566°C), a steam turbine generator, and an air-cooled condenser. On this day, the system was being tested by heating molten salt at the top of the glowing tower to 1050°F (566°C), then using the resultant thermal energy to drive steam turbines, which in turn sent electrical power to the Nevada grid.."
