Our Design My windmill is blue today Our Experiment I used the fan on 3 Results Reading 1 Current [18 ] mA Reading 2 Current [ 18] mA Reading 3 Current [ 18] mA Reading 4 Current [18 ] mA Average Current = [18] mA Windspeed at fan = [4.7] ms-1 Resistance = [100 ] Ohms Power = I * I * R (remember to convert mA to A) P=0.0324 So with a windspeed of [4.7ms-1] our turbine generates an average current of [18 ] mA delivering [32.4 ] (convert W to mW) mW per second so in 10 minutes it could generate [ 19,440 ] 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 [ 252 ] seconds of playback time, enough to listen to about [ 1.4 ] 3 minute songs. Thoughts I'd like to add another rotator arm
