Our Design
cream one, four blades

Our Experiment
made it go round with wind
Results
EDIT WITH YOUR VALUES
Reading 1 Current [17.5 ] mA
Reading 2 Current [ 17.3] mA
Reading 3 Current [ 17.4] mA
Reading 4 Current [ ] mA
Average Current = [17.4 ] mA
Windspeed at fan = [5.6 ] ms-1
Resistance = [100] Ohms
Power = I * I * R (remember to convert mA to A) 302.76 correction 30.276

So with a windspeed of [s ] our turbine generates an average current of [17.4 ] mA delivering [30.3 ] (convert W to mW) mW per second so in 10 minutes it could generate [18166] 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 [ 236 ] seconds of playback time, enough to listen to about [ 1.3 ] 3 minute songs.

Thoughts
add more wind to get more electricity
add more blades
