 | This project demonstrates that it is possible to use the heat of the sun to produce a movement. The technical principle consists of boiling a liquid (e.g. water) in a closed tank using solar energy. To obtain a temperature sufficient to boil water, parabolic mirrors are used to focus the sun's rays ... »

 | Building 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 steam (steam ... »
