 | 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 ... » faraday, torch, magnet, coil, transferring

 | This DIYs project of a solar oven was part of a contest organised by the Juvene Foundation and the Swiss television (RTS-découvertes) during Summer 2011. The idea was to propose an easy experiment which needed only extremely cheap and easy to find materials and which would encourage children to ... » experiment, insulating, rays, greenhouse, panels

 | The construction of a solar hot water panel helps to understand how it is possible to heat water with the Sun. The basic principle is to circulate water in a black pipe placed behind a glass exposed to the Sun. Thanks to the greenhouse effect and the black colour that absorbs most of the Sun's rays, it is ... » circulate, pipe, greenhouse, absorbs, rays
