MAKE magazine never fails to amaze. And this time, John Park tackles a DIY wind-powered generator—and he shows you how to do it! Before you start watching the video tutorial, make sure to download the PDF of this project for reference.
So you want to build this wind-powered generator? Great, but just know that this isn't going to help you be independent of energy providers. You'll still be on the electricity grid, but you'll be saving a decent chunk of money of your electricity bill.
To make the wind-powered generator, you'll need a motor from an old exercise treadmill and some pieces of PVC pipe (but that's not all—it's just the main materials needed). After building your own successfully, you'll be able to get a good 20 volts for a steady 15mph wind.
