1.  By Chase Thompson, Stephanie Miller, & Josh Chandler

2.  300 ft of 30 gauge copper wire  Brass Bar  6 rare earth magnets  fan blade  Pin wheel  Sheet of wood  Paint

3. Mechanical Aspects  Propeller initiated by wind spins turning brass shaft  Magnets attached to the shaft are turned in sequence Electrical Aspects  Magnets rotate perpendicular to copper wire creating an electrical current  Current flows from the wire to the flower attachment illuminating the lightbulb

4.  Theoretical  KE =   P Theoretical = KE/t   P theoretical = 13.506 watts. Actual P = IV  P= (25)*(.6) = 15 watts  Efficiency  [(Actual - Theoretical)/Theoretical] * 100  V = IR (Ohms Law)  A = Area  L = Length  p = Density of Air  V = Voltage  P = Power(watts)  I = Current(Amps)  v = wind velocity  T = time  R=Resistance p=1.204kg/m 3 A= * (.127m) 2 =.0314m 2 =.05067m 2 V=8.94 m / s

5.  Original idea using gears did not work  Additional amount of copper wire was needed  Initial propeller used was not strong enough  Coiling and mounting the copper wire  Strength of magnets needed to be increased  Maintaining alignment of the brass bar

6.  Gained experience in converting mechanical energy into electrical energy  Applied principles of physics in a real life situation  Learned to work as a team  Improved planning and time management skills
