  1. Working With Wind Energy

  2. Learning Objectives • Learn about wind energy conversion • Design a wind turbine • Construct the wind turbine • Test the wind turbine • Evaluate Performance

  3. A Wind Turbine • The wind hits the blades… • Shaft leads to a gearbox whose output leads to a generator to make electricity • Usually has 2 or 3 blades WIND

  4. Many blade designs

  5. Your Challenge > 1ft, 30cm Design, construct and test your own wind turbine design Lift weight – 15 cmas quickly as possible Maximum1 minute No human interaction! Blowdryer at least30cm away from turbine

  6. Turbine Requirements > 1ft, 30cm Must have a rotor shaft around which to wind up given weight Must be freestanding (no human interaction) Must use only materials provided

  7. Test Procedure > 1ft, 30cm Blowdryer at least 30 cm away from turbine No human interaction with turbine Attach weight around rotor Up to 1 minute to wind up weight for 15cm Record time to wind up weight

  8. Materials wooden sticks bendable wire string paperclips rubber bands Toothpicks aluminum foil, plastic wrap tape, wooden dowels paper, cardboard

  9. Procedure Teams of two (2) Develop and sketch your design Construct initial design Preliminary test Modify design, if necessary Final test

  10. Evaluate Your Design • Efficiency of design may depend on • Cost of materials • Speed (rotations per minute) • Power (time to wind weight) • Possible measure of efficiency: • Eff. = (Cost of materials) / (time [sec] to lift weight) • Are two designs that have the same rotational speed equally as “good”?
