That “Other” Solar Tower Technology

That “Other” Solar Tower Technology

of Solar Power Towers is dependent upon heliostats. Fields of them, all reflecting the sun’s light to a central tower. There, the highly concentrated sunlight produces equally high temperatures. The heat is then used in an otherwise conventional Rakine Cycle thermal power plant to generate steam that runs a turbine to generate electricity. The first of these systems were built in the early 80′s in Russia, Europe Japan and slightly later in the US. Salts with higher melting temperatures can contain more sensible heat storage and were being used for their efficiency advantage over simply heating water.
