2-liter Wind Turbine - "This is a vawt turbine that I made with 2 liter bottles. I will be making many different designs to find the right on to fit my needs. My goal is to make a $10.00 turbine that everyone in the world can make. If anyone has a design they would like me to try, you can do a video response or just comment on the video. I will do my best to make it happen."
