 | Making a battery helps to understand how a chemical reaction can produce electricity. It shows also that in a battery there is no real stock of electricity, but the chemical products needed to generate some. It is important to understand how batteries work as they are more and more used in our daily ... »

 | 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 ... »

 | 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 ... »
