Concrete absorbs heat. So how is it used in solar towers?
Question:
but the material used is concrete which absorbs heat. so in what way does it work?
Answer:
"Solar towers" do not produce electricity. Solar cells do, and they are not used in "towers." You may be thinking of a tower, built out of steel, concrete or other material, that contains a large mirror to capture solar rays, concentrate the rays into a very hot one and beam it to pipes filled with water which then turns to steam which turns a turbine which produces electricity.
