Concrete absorbs heat. So how is it used in solar towers?

Question

actually solar towers produce electricity. it should not absorb heat.
but the material used is concrete which absorbs heat. so in what way does it work?

Answer 1

"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.
