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 ... »

Hydroelectric power plant 1

This project helps to understand how hydropower (energy from water in motion) can be transformed into electricity. Hydropower is a renewable energy regenerated through the water cycle. The Sun powers this cycle by evaporating water (from e.g. rivers, lakes or seas). This water condenses in the ... »

Solar thermal concentrator

This 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 ... »
