  1. Not so easy it seems… Windmill Energy

  2. Introductions

  3. Device Design Overview

  4. Final Material List • 0.5m x 0.5m plywood • 2 2x4s • Metal rod • Dowel rod • 2 Basketball cups • 550 ft of wire • 4 ceramic block magnets • Nails / Clips / Glue

  5. Electrical/Mechanical Aspects Generator Version 7.0 Max Voltage: 1.7 Initial designs: Cardboard Box, PVC pipe Windmill Version 2.0 Initial Design: Cans instead of Cups

  6. Efficiency • Wind Speed = 10 m/s at 6 inch from fan • Power = 0.5 x air density x area exposed to wind x velocity cubed • Given that our area is 14 in^2, or 0.00903224 meters^2, the maximum power is 5.53 watts. • Our generator produced 0.0017 Watts, giving an efficiency of (0.0017 / 5.53) * 100 = 0.0307%

  7. Construction Issues • Magnet alignment inside the generator • Connecting the windmill shaft to the generator shaft • Structure of the generator • Initial windmill design did not spin fast enough • General friction of moving parts

  8. Conclusions
