Our Design A combination of two windmills, one from paper plates and one from orange card in classic beach windmill design Our Experiment We tried these two connected in series and parallel. We got enough power to run the radio, even with just the small fan blowing! Results Reading 1 Current [ 15] mA Reading 2 Current [ 14.5] mA Average Current = [14.75 ] mA Windspeed at fan = [s ] ms-1 Resistance = [100 ] Ohms Power = I * I * R (remember to convert mA to A) 0.02176 So with a windspeed of [s ] our turbine generates an average current of [14.75 ] mA delivering [21.76 ] mW so in 10 minutes it could generate [21.76 * 600 = 13053 ] 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 [ 169.5 ] seconds of playback time, enough to listen to about [ 0.9 ] 3 minute songs. Thoughts Want to add in more turbines to make a bigger wind farm.
