I watched this short TED Talk twice today because I was intrigued by ideas for using wind energy as presented by Saul Griffith. The video does a nice job of presenting ideas for using wind energy. The first half of the talk is probably more accessible to middle school and high school students than is the second half of the talk. The kite-powered hydrafoil might inspire some neat science fair experiments. The talk is less than six minutes so it won’t take much time to show in classroom.
