About Our Team

Our team is from Grand Rapids, Michigan, United States. We are from KCTC, and are in the 9-12 age category.

This was a one man team with little background knowledge about windmills.

Was a REcharge Labs MacGyver Windmills kit used for this project? No

What was the biggest challenge in trying to get your windmill to work properly? Getting the fan to rotate properly without any sort of oil or anything.
