In this Education video tutorial you will learn how to build a wind turbine with PVC windmill blades. This project when completed will charge a 12V battery. You can turn a motor in to a generator. When you spin the shaft on the generator, electricity is generated. So you get a motor with a flywheel and attach the turbine blades to it. When the blades turn with wind action, electricity will be generated. Take PVC pipes, 8" in diameter and 24" long. Cut the blades out of the pipe as per directions in the video and attach them to the flywheel. You then have to make a tail that will keep the blades pointing in to the wind. Follow the directions in the video to complete the project.
