The results indicate that this hypothesis should be rejected. Because of the results of this experiment, I wonder if vertical axis wind turbines produce more electricity than horizontal axis turbines. If I were to conduct this project again I would made a bigger wind tunnel and use a more powerful fan so I could test more sizes of blades and styles of wind turbines. Back to Top Research Report Introduction Wind turbines are machines that generate electricity. They produce no pollution but they also have down sides.
Wind turbines are a great way to get energy without pollution.
They were originally used for pumping water for livestock or for grinding grain into flour. Windmills were used throughout Europe and parts of Asia. The Dutch are famous for their windmills. The Dutch built a great wall out in the sea and make something like a lake. Windmills were used to pump the water out, and dry land was formed.
