 | The construction of a small steam engine helps to understand how this technology can tranform heat into a mouvement. If some water is heated in a closed container and evaporates, a pressure is created inside. This pressure is due to the increase of water volume during its transformation into ... »

 | 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 ... »
