[Solar Energy] Concentration Solar: Following Archimedes Intuition

The legend claiming that Archimedes used polished shields to concentrate solar power on Roman ships invading Syracuse to burn them and repel invasions has become, in modern times, a way to produce energy using lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. The concentrated light is then used as a heat source for a conventional power plant or is concentrated onto photovoltaic surfaces.
