 | 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 ... »

 | Building a parabolic solar grill helps to understand the principle of sunlight concentration. This technique is already used in experimental solar power plants. Parabolic mirrors focus the Sun's rays on black pipes in which water circulates. The heated water expands and turns into steam ... »

 | 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 ... »

 | Building a solar torch (flashlight) helps to understand how it is possible to store the energy of the Sun and use it later at night. photovoltaic cells transform the energy of the sun in electricity that can be stored in a rechargeable battery. Photovoltaic cells are now widely used and can be even ... »

 | This DIYs 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 ... »
