How does wind spin those giant turbines? It seems like even high-speed winds wouldn’t move it very quickly with how heavy the turbine blades must be.
In: Planetary Science
The blades are on a bearing – something that allows rotation with very little friction. At that point, the weight isn’t very important. The blades spin *very easily*.
Combine that with their enormous length, which gives the wind very powerful leverage on the shaft, and they spin with ease.
