  1. Wind Day 3 by John Zavalney

  2. Wind Day 3 Quick Write Have you ever seen wind do work? Describe what and where you saw it?

  3. Wind Day 3 • It has been done for a long…long…time • Wind use PowerPoint • Watch & listen to the following presentation • Take some notes on when, where and how wind energy energy was captured and used

  4. Wind Energy:A Historical Perspective This presentation is adapted from KidWind Basic Workshop slide show http://www.kidwind.org/lessons/PPoint.html

  5. Early “WINDMILL” in Afghanistan (900AD)

  6. Dutch Windmillsas early as 1300

  7. Water Pumpers

  8. Jacobs Turbine – 1920 - 1960

  9. Smith-Putnam Turbine Vermont, 1940's

  10. Modern Windmills

  11. Orientation Turbines can be categorized into two overarching classes based on the orientation of the rotor Vertical AxisHorizontal Axis

  12. Horizontal Axis Wind Turbines • Rotors are usually Up-wind of tower • Some machines have down-wind rotors, but only commercially available ones are small turbines

  13. Types of Electricity Generating Windmills • Small (10 kW) • Homes • Farms • Remote Applications • (e.g. water pumping, telecom sites, icemaking) • Intermediate • (10-250 kW) • Village Power • Hybrid Systems • Distributed Power • Large (250 kW - 2+MW) • Central Station Wind Farms • Distributed Power

  14. 10 kW 50 kW 900 W 400 W Modern Small Wind Turbines:High Tech, High Reliability, Low Maintenance • Technically Advanced • Only 2-3 Moving Parts • Very Low Maintenance Requirements • Proven: ~ 5,000 On-Grid • American Companies are the Market and Technology Leaders (Not to scale)

  15. Large Wind Turbines • 450’ base to blade • Each blade 112’ • Span greater than 747 • 163+ tons total • Foundation 20+ feet deep • Rated at 1.5 – 5 megawatt • Supply at least 350 homes

  16. Large Wind Turbines Each blade 112’

  17. Large Wind Turbines Each blade 112’

  18. Electrical Production

  19. Where do we get our electricity?

  20. This PowerPoint was modified from the KidWind web site: http://www.kidwind.org/index.html Wind Energy 101 : http://www.kidwind.org/lessons/PPoint.html

  21. Wind Day 3 Build a Wind Turbine Simple with limited capabilities or..commercial with multiple capabilities Here is where you follow the directions for the materials you have

  22. Wind Day 3 • Wind Turbine Experimentation • Measure electrical output • Identify variables like wind speed and ground obstruction that effect turbine speed • Change one variable at a time and record data as time permits

  23. Wind Day 3 Wind Turbine Experimentation Activities tomorrow will focus on blade design

  24. Assessment Work on FINAL PROJECT PowerPoint Presentation Wind Day 3 • Gather research and resources • Putting your PowerPoint together
