WINDMILL ENERGYNot so easy it seems…
Introductions
Device Design Overview
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
Electrical/Mechanical AspectsGenerator Version 7.0Max Voltage: 1.7Initial designs: Cardboard Box, PVC pipe
Windmill Version 2.0Initial Design: Cans instead of Cups
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%
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
