Well done animation and a great idea. Given the topic of your animation, if you haven't seen it yet you should take a look at the book
The Boy Who Harnessed The Wind. A great story about someone looking at the utilization of simple, easy-to-construct windmills from the other side of the equation - the builder/user. I found William Kamkwamba's story to be very FIRST-like, in terms of both his ability to put things to use doing jobs for which they were never originally designed, and (more importantly) his skillful innovation and ability to see a solution to a tough problem. We are giving copies of the book to each of our team captains this year.
