1. 1 Working With Wind Energy IEEE TISP Training Workshop Pittsburgh, PA, 23-24 October 2009 Douglas Bowman, PE Central Arkansas Chair, IEEE Lead Engineer, Southwest Power Pool

2. 2 Activity Goal l Build a wind turbine with simple materials l The wind turbine must withstand the wind generated by a fan or hair dryer and rotate for 1 minute to lift a small object

3. 3 Activity Objectives l Learn about wind energy conversion l Design a wind turbine l Construct the wind turbine l Test the wind turbine l Evaluate Performance

4. 4 Why is this experiment useful to teachers and students? l Learn about wind energy and wind turbines l Learn about the concepts of forces and motion l Learn about engineering design l Learn how engineering can help solve societal challenges l Learn about teamwork and problem solving

5. 5 Principles & Standards for School Mathematics l Geometry: l Use visualization, spatial reasoning, and geometric modeling to solve problems l Analyze characteristics and properties of two- and three- dimensional geometric shapes and develop mathematical arguments about geometric relationships l Problem Solving: l Recognize and apply geometric ideas in areas outside of the mathematics classroom l Apply and adapt a variety of appropriate strategies l Communication: l Communicate mathematical thinking coherently and clearly to peers, teachers, and others

6. 6 U.S. Available Wind Power P wind =0.5 Av 3

7. 7 Getting Wind Power to the Grid

8. 8 End Result is Work

9. 9 Outline and Procedures l Divide into teams of three (3) l Review the requirements l Agree on a solution and create a sketch of your design l Build a model of your design with given materials l Test your model

10. 10 Redesign after testing l Discuss and agree upon a redesign l If needed after testing, or l to enhance the previous design l Rebuild your wind turbine l Retest your model l Answer Evaluation Phase questions as a team

11. 11 Evaluation Phase Questions l Did your design succeed? If not, why did it fail? l Did you decide to revise your design? Why? l What is one thing you would change about your design based on your experience? l How would you modify the instructions to create a better experience for the participants?
