DIY Vertical Axis Wind Turbine

Share

This is a neat project. A site called hackaday posted this project. It’s essentially a homemade wind generator (generates electricity from wind.) It’s not one of those large windmill style turbines that you might have seen. This is a vertical design. They’ve sliced pvc pipe lengthwise in half to catch the wind. One advantage of a design like this is that it would work with wind from ANY direction. Their design drives a small DC motor. (DC motors can be used two directions…. hook up a current and get motion or supply motion and get current…)

This is one project that I may put on my to do list. It looks like it could be enough to keep a few batteries charged at least. I haven’t found an estimate of how much wind it would take to turn it. (That MAY be the real catch.)
