The Gemasolar Concentrated Solar Power plant near Seville, Spain, has achieved a full 24 hours of solar power production one month after starting commercial operation. The 19.9 MW plant uses a huge array of mirrors to heat a molten salt storage system in the central tower which is then used to run steam turbines, resulting in the ability to continue energy production after the sun goes down.
