Concentrated solar power plants are based on the concentration of solar rays on a fluid. When this fluid reaches the boiling point, the steam that it generates is used to move a turbine and this subsequently generates electricity.
It is formed by curved mirrors, concave channel shaped that concentrates its radiation over a pipeline that carries oil with high temperatures.
Parabolic cylindrical collectors are also known as high temperature collectors. This means they need to reach temperatures above boiling, then they are used in industrial plants dedicated to the generation of electricity.
