Pumped-storage hydroelectricity

In the Toules dam near the Great St. Bernard pass (Switzerland), an artificial island with 2,240 m2 of photovoltaic solar collectors has been built. In the canton of Glarus (Switzerland), the wall of the Muttsee dam has been covered with solar cells. These high-altitude solar power plants offer ... »

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 ... »

Solar electric motor

This project helps to understand how an electric motor works (how it is possible to create a movement with electricity). Many electrical appliances use this technique  (mixer, cd player, hair dryer, etc.). By generating electricity from the Sun, this project shows that there are alternative ... »

Solar boat

Building a solar boat helps to understand how photovoltaic solar cells can be used to produce electricity. Toy using solar cells represent often machines that do not exist or which are not logical. It is not uncommon indeed to find toys of helicopters or windmills powered by photovoltaic cells. ... »

Adiabatic solar air conditioner

This project shows how to build an 'ecological air conditioning system'. The electricity of the fan is generated by a photovoltaic cell and the air is cooled simply by evaporating water. Conventional air conditioners are very energy consuming. They work like a fridge and need a lot of electricity ... »
