Faraday torch

Building a Faraday* torch helps to understand how it is possible to produce electricity from a magnet, a copper coil and a movement.  The same principle is used in most electricity plants.   Depending on the plant, the movement is produced by different means (for instance by transferring the ... »

Solar Steam machine

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 ... »

Steam engine

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 ... »
