Vertical axis wind turbine

Building this DIYs project helps to understand how wind turbines work and generally how to transform a mechanical movement into electricity. This principle can be found in devices we use every day (bicycle dynamo, car alternator, etc.). The same principle is also used by most of our electricity ... »

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 ... »
