Our Design YELLOW, 4 blades Our Experiment I made it go around by pitting it next a fan Results Reading 1 Current [15.1 ] mA Reading 2 Current [14.9 ] mA Reading 3 Current [15.3 ] mA Reading 4 Current [14.6 ] mA Average Current = [0.0599 ] mA correction 14.975 Windspeed at fan = [s ] ms-1 Resistance = [100 ] Ohms Power = I * I * R (remember to convert mA to A) 35.88 correction 0.0224 So with a windspeed of [s ] our turbine generates an average current of [14.97 ] mA delivering [22.4 ] (convert W to mW) mW per second so in 10 minutes it could generate [13440] 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 [ 174 ] seconds of playback time, enough to listen to about [ 1 ] 3 minute songs. Thoughts Make it lighter by using glue instead of metal pins.
