Our Design s shaped yellow one Our Experiment we tried moving the generator to allow this one to rotate around a vertical (and horizontal) axis but it didn't want to turn Results we sadly didn't get any energy out of this one. Reading 1 Current [ ] mA Reading 2 Current [ ] mA Reading 3 Current [ ] mA Reading 4 Current [ ] mA Average Current = [I ] mA Windspeed at fan = [s ] ms-1 Resistance = [R ] Ohms Power = I * I * R (remember to convert mA to A) So with a windspeed of [s ] our turbine generates an average current of [I ] mA delivering [P ] (convert W to mW) mW per second so in 10 minutes it could generate [P * 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 [ ? ] seconds of playback time, enough to listen to about [ ? ] 3 minute songs. Thoughts REPLACE THIS WITH YOUR THOUGHTS: HOW COULD YOUR WINDMILL BE IMPROVED, HOW COULD THE EXPERIMENT BE IMPROVED, IS 100% EFFICIENCY ENERGY TRANSFER REALISTIC, WHAT WOULD YOU ASK AN EXPERT, HOW CAN TECHNOLOGY SUPPORT SCIENCE TEACHING AND LEARNING, ETC...
