Parabolic troughs at a solar power station. A parabolic trough consists of a linear parabolic reflector that concentrates light onto a receiver tube positioned directly above the middle of the mirror. The tube is filled with a working fluid, such as molten salt, which is heated to high temperatures by the focused sunlight, and used as a heat source for a power generation system. Photographed at the Solana Generating Station near Gila Bend, Arizona, USA. | |
