1. Achy Breaky Fart Garrett Rich, Lane Dukart, Bart Ring

2. Work Time Team member Bart Ring diligently working with the finer aspects of the project. Lane Dukart studies his math calculations Garrett Rich spices up the power point presentation

3. Materials DC motor – generator Cardboard - propellers Molding Clay/Krazy Glue - Support of the base PVC Pipe - Framework of windmill Duct Tape - Everything Butt Splice - Wire Wood Block – Base Drill Head – Cranks generator

4. Equations for Windmill Power = Amps x Voltage Amps =.0125 Voltage =.8 volts Power = (.0125) x (.8) =.01 volts

5. Equations for Air Power =.5 x p x Area x Velocity 2 p = 1.204 Radius of Fan =.2 meters Area of Fan = pi x.04 m =.125 meters 2 Windspeed = 22 mph = 9.83 m/s Power =.5 x 1.204 x.125 x 9.83 3 = 71.5

6. Efficiency Equation Efficiency = (power mill / power air ) x 100 Efficiency = (.01 / 71.5) x 100 =.0139 % Killer efficiency

7. Conclusion We took a different path in building our windmill than the other groups. We used what was around us and put together a horribly efficient, but workable windmill. We had a blast making this windmill, half the fun was wondering if the device would produce us some power.
