  1. 21. Heliostat Design

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Nils Björkman; [2014]
    Keywords : Solar Power; Heliostat; Thermal solar power; Solar Power Tower; Central Receiver System; Solenergi; Heliostat; Termisk solenergi; Solar Power Tower; Tornsolkraftverk;

    Abstract : A heliostat is a motorized mirror used in a Solar Power Tower plant. The technology has been around since the 1970’s, and involves hundreds or thousands of heliostats reflecting the sun’s rays to the top of a high tower, where the incident solar energy is converted to heat energy, which in turn is used to drive steam turbines and produce electricity.
