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 ... »

Steamboat

Building a steamboat helps to understand how it is possible to tranform heat into a mouvement. If some water is heated in a closed container and evaporates, a pressure is created inside. This pressure is due to the increase of water volume during its transformation into steam (steam takes about ... »
