Solar hot water panel

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 ... »

Solar house

Building a solar house model helps to understand how it is possible to use the power of the Sun to save energy or even to be completely independent from the energies we normally use in our buildings. Even if they are still rare, some buildings already use only renewable energies. These 'autonomous ... »

Solar chimney

The use of sun energy is not limited to photovoltaic cells for electricity or solar thermal collectors for heating. Other ideas exist, often still experimental, like the solar chimney. A huge project of this type is planned in Australia with a tower 1 km high!   The construction of a solar chimney ... »

Thermometer and monitoring board

In order to adjust a central heating and save energy, room temperatures must be measured with a thermometer.   The thermometer was invented in the 17th century and its working principle is still used today. Household thermometers contain, inside a glass tube, a small amount of coloured alcohol ... »

Maquette géothermique

Comme son nom l'indique, la géothermie concerne la chaleur (thermie) se trouvant dans sous-sol de la terre (géo). Cette énergie provient principalement du noyau terrestre dont la chaleur est considérée, à l'échelle humaine, comme une ressource quasi infinie, ce qui la classe parmi les ... »
