A solar tower power plant receives an average direct component of concentrated incident radiation of 950 W/m2. The conversion efficiency of the heliostats into thermal energy is 53%. The operating temperature of the fluid is 560 oC and the sink temperature is 100 oC. Calculate the area of heliostats and the land area required to generate 100 MW of thermal power. Assume that the heliostats occupy one-quarter of the area of the power plant site and the realizable thermal efficiency is 70% of the ideal Carnot value.
