Solar popper

Apart from photovoltaic cells, there is another way to produce electricity with the Sun. This technique uses the Sun to heat water or air in a closed tank. High temperatures are reached by using parabolic mirrors which concentrate the Sun's rays. The heat increases the volume of water or air in the ... »

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 ... »
