 | 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 ... » turbines, transform, bicycle, dynamo, alternator
