Solar Thermal Energy Utilization

The ener~y crisis in 1973 and 1979 initiated a great number of activities and programs for low and high temperature applica­ tion of solar energy. Synthetic fuels and chemicals produced by solar energy is one of them, where temperatures in the range of 600-1000°C or even higher are needed. In principle such high temperatures can be produced in solar towers. For electricity tower plants production,...
