Yesterday we tried completing this project but it was too windy and ended in injury (Cisco's fingers got in the gears, band aid followed). Today it was a little less windy so the boys were able to finish the testing which involved timing the lifting of the weight. So after a variety of blade positions and removing and adding blades....the most efficient windmill was discovered. And here are the results and some commentary!
The follow up activity was to make a top and use the weight and ratchet system to release the top.

The boys are doing really great. They seem to work good together.
Very cool project! I ordered this kit for my boys for Christmas. They have enjoyed seeing what your guys have done with it. Did you buy a teacher's guide with yours, or just the basic kit?

we ordered it through the Homeschool Buyers Co-op. It's also available on the Lego education website and comes with a cd-rom with lesson plans and activities, animated shorts and all kinds of cool stuff. Here's the link:
