National Geographic has a neat little interactive activity designed to help people understand how wind turbines generate power. Harness the Power of Wind walks viewers through the basics of wind turbine design. After reviewing the design principles you can design and “test” your wind turbine’s efficiency. You can adjust the height of your wind turbine, the wind speed, the altitude, and the blade radius.

Applications for Education
Harness the Power of Wind could be used for teaching a lesson on wind power that incorporates basic physics and mathematics concepts.
