Photographer's note: "Aerial photograph of Crescent Dunes Solar, a 110MW tower style concentrated solar power plant with molten salt storage near Tonopah, Nevada, USA. 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.."

Photographer's note: "Workers adjust a heliostat at Crescent Dunes Solar. 10,347 heliostats (mirrors) are part of the project. Each heliostat is 34 feet tall, uses 35 mirrors, and has a surface area of 1258 square feet, or 115.7 square meters. Aerial photo, Crescent Dunes Solar, near Tonopah, Nevada, USA."
