Cheap Verticle Wind Turbine
We are working on an inexpensive yet efficient wind turbine generator for use by low-income communities all around the world. Our goal is to build the best turbine using readily available materials, and an easy-to-build design. This is an ever-evolving project which started with a typical horizontal propeller. However we decided that the vertical airfoil design would work better for us in this instance. If you have any comments or suggestions, please comment.
