Team Members: John Smolko, Michael Warden, Anthony Hathaway, and Tim Pobst Tasks: •Build Windmill Energy •Learn about Electricity while working with a team •Follow the guidelines and requirements Started off with three different designs and came to an agreement •Fans built out of cardboard, styrofoam center, geared with Legos to an axle directly through the generator with neodymium magnets •Sits on a wooden base with a wooden stronghold out the center of the base to hold the generator and fan •Materials: wood, cardboard, wire, magnets, nails, Legos, styrofoam, and bulb • Given fan gives kinetic energy •Captured wind in the rotation speeds up to turn the axle •Axle is directly through the generator •Electricity builds up within the device •Average voltage – 1.4 Volts •Efficiency - Actual ∕ Theoretical •Calculations – Theoretical P = ½ ρ A V³ , Actual P = V * I •P = ½ * (1.225 kg/m³) * (π(.17272 m)²) * (1.7 m/s)³ •P = 1.4 Volts * Current •Cost – $5.oo Total, $3.00 for magnets and 1.50 for Light bulb •Team worked constructively together •Took a few good meetings to solve and figure situations •Learned about Mechanical and Electrical Aspects of a Windmill •Give us an A!!!
