Design Plexiglas supported generator with 30 gauge, 24 gauge and 20 gauge wire wrapped in a coil A metal screwdriver through a whole in the center supporting the magnet and the blades Styrofoam support for the blades attached to the screwdriver Pepsi cans cut and glued into wind blades Base support for proper height to catch wind

Mechanics and Electrics The wire around the Plexiglas creates a coil which conducts electric current when a magnet is spun at a high velocity. The wind acts as a catalyst to spin the blades which spins the magnet The base support places the blades at the ideal height so that they spin with with the greatest possible velocity.

Estimated Efficiency Calculations Power =.5 × ρ × a × v 3 P =.5 × kg/m 3 × π(.174 m) 2 × (8.94 m/s) 3 KE = 41.6 watts Actual Power Watts = Volts × Amps.85 volts ×.021 amps =.0179 watts Efficiency.0179 / 41.6 volts × 100 = %

Issues First generator failed miserably Had major issues getting wire from the store Hot glue ran out many times Hot glue melted the Styrofoam support Sharp edges on the cans

Conclusions This project demonstrated how wind energy works in the real world. Could have created a more efficient device with more time and materials (gear system, fly-wheel, better blades, bigger coil, etc.) A successful windmill that generates electric current.
