Wind Turbine Blade Angle Experiment Problem: Which degree of a fan blade produces the most voltage? Hypothesis: I believe that turning the fan blade to a 45 degree angle is the best solution for creating more energy. This is because more wind will pace over the surface of the blade causing it to spin faster. If the fan blade is at a 90 degree angle I believe it will also provide a significant amount of energy. Data: Voltage Produced:
