Introduction - what were you investigating?

Prediction - will your design produce enough energy to charge an iPod for an hour in the 10 minutes you have?

Conclusion - What did you discover?
design is paper plates with red cones attached to end fins

average current reading is: 4.4 mA, then on highest fan 9 mA

Evaluation - How would you improve your windmill design if you were doing this experiment again?

What would you like to ask a power expert about this experiment?
