 | Concept Building a solar boat is a good way too experiment the use of photovoltaic solar cells. Solar boats are an ecological means of transportation because they use the sun, a renewable and environmental friendly energy. In order to navigate by night and when the sun is too weak, solar boats ... »

 | This DIYs 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 ... »

 | 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 DIY shows that there are alternative energy ... »
