Solar oven

This DIYs project helps to understand how the greenhouse effect can be used to 'trap' and increase the heat of the sun.   The sun's rays (short wavelengths of visible light) penetrate through the glass of the oven and heat the elements inside. When this heat is reissued as infra-red radiations ... »

Solar thermal concentrator

This DIYs project shows how it is possible reach high temperatures by concentrating the sun's rays. This technique is already used in experimental thermal power plants in California and France. These plants concentrate the sun's rays in a single point with a field of mirrors. Like in most power ... »
