 | Apart from photovoltaic cells, there is another way to produce electricity with the Sun. This technique uses the Sun to heat water or air in a closed tank. High temperatures are reached by using parabolic mirrors which concentrate the Sun's rays. The heat increases the volume of water or air in the ... »
