That's because they're perfectly shaped to capture the wind's kinetic energy. The blades spin a shaft, which is connected to a generator. Inside the generator, copper coils turn through a magnetic ...

probably the simplest and smallest wind turbine we’ve seen. His use of a 3-phase motor from a CD-ROM drive as the generator isn’t particularly unexpected, these motors are ubiquitous and ...

We’ve all got a pretty good mental image of the traditional wind-powered generator: essentially a big propeller on a stick. Some might also be familiar with vertical wind turbines, which can ...
