Wind Energy Science Kit

"With the Wind Energy Science Kit you can build a miniature power generation system that converts wind into electrical energy. Experiment with the pitch (angle setting) of turbine blades and find out the optimum number of blades for generating electricity. Nine blades, with three types of profiled blade based on NASA aeronautics and one type of poly-propylene sheet blade, provide the opportunity to find the perfect balance of wind resistance, weight and angle."
