Our Design Paper plate and coctail sticks. Flower shape. Our Experiment Tried it with lots of different speeds, and fans. Results Reading 1 Current [10.5] mA Reading 2 Current [11.3] mA Reading 3 Current [11.7] mA Reading 4 Current [11.9] mA Average Current = [11.35] mA Windspeed at fan = [1.7] ms-1 Resistance = [100] Ohms Power = 0.01288w So with a windspeed of [1.7] our turbine generates an average current of [11.35] mA delivering [12.88]mw so in 10 minutes it could generate [12.88*600] mW. If playing music on an iPod classic consumes about 77mW per second, 10 minutes of turbine time (assuming 100% energy transfer efficiency) can power [100] seconds of playback time, enough to listen to about [0.6] 3 minute songs. Thoughts With more power, you should have less blades and more surface area. With less wind speed you might get more power than otherwise with more blades.
