Solar Power Tower

The Solar power tower consists of a field of thousands of mirrors (heliostats) surrounding a tower which holds a heat transfer fluid to concentrate light on a central receiver atop a tower (Fig. 1 c). Each heliostat has its own tracking mechanism to keep it focused on the tower to heat the transfer fluid, which is then used to run a turbine.
