Parabolic solar cooker

The construction of a parabolic solar cooker helps to understand how it is possible to concentrate the solar rays to reach higher temperatures. This technique is used in experimental power plants in California and France. These plants use a field of mirrors that concentrate rays to a single point ... »

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 ... »
