Project Overview
Our blade type is a rectangle with a slant on the side of the blade with a flat top. We started with three blades, but then we changed to four blades because it created more energy. Our gear ratio is a big 64-tooth gear with a small 8-tooth gear, because we realized this ratio created more energy than our other ratio (32-thooth and 16-tooth). We used corrugated cardboard for the blades and hot glue and tape to attach the dowels to the blades.
