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 ... »

My little turbines

The construction of wind or water turbines connected to a small generator (alternator) allows to experiment two different ways of transforming motion into electricity.Most power plants in the World produce the movement required to opterate the alternator by heating water with coal, natural ... »

Faraday torch

Building a Faraday torch helps to understand how it is possible to produce electricity from a magnet, a copper coil and a movement.  The same principle is used in most electricity plants. Depending on the plant, the movement is produced by different means (for instance by transferring the ... »

Parabolic solar Grill

Building a parabolic solar grill helps to understand the principle of sunlight concentration.   This technique is already used in experimental solar power plants. Parabolic mirrors focus the Sun's rays on black pipes in which water circulates. The heated water expands and turns into steam ... »
