Windmill Energy

This comprehensive guide delves into the fundamentals of windmill energy, focusing on designs, efficiency equations, and common construction challenges. Team members Gerrit Hale, Heather Boynce, Marion Osborne, and Thomas Thurman provide insights into creating an effective horizontal-axis windmill. Key aspects include propeller design, optimal wire and magnet selection, and ensuring frictionless operation for maximum energy capture. The efficiency equations explore kinetic energy and power output, highlighting the inherent limitations due to friction and resistance.

Presentation Transcript

  1. “ Hit or Miss” Windmill Energy • Gerrit Hale • Heather Boynce • Marion Osborne • Thomas Thurman Team Members :

  2. Design Simplistic design: • Propeller • Horizontal Axis • Magnet • Copper Wire • Stand

  3. Design/Construction Issues • Propeller • Catching enough wind • Turning the horizontal axis • Wire • Not having right kind • Wrapping the generator the best way • Having enough to form a strong magnetic field • Horizontal Pin • How to make it Frictionless. • Magnet • Best magnet • How to attach to produce magnetic field.

  4. Mechanical/Electrical Aspect • Horizontal pin used to easily collect a direct wind source • Horizontal pin needs to be frictionless to produce the most energy. • Connecting the copper wire and wrapping it to form a current with the rotating magnetic field.

  5. Estimated Efficiency Equations • Kinetic energy of fan: • KE= (1/2)mv^2 • M= mass in kg • V= velocity of fan blades • Power of wind in watts: • P= (1/2)mv^2 = (1/2) ρ(air) Av^3 • A= area exposed to wind • V= wind speed • Rho= air density about 1.225 kg/m3 - It would be impossible to be 100% efficient due to resistance, friction and human error.
