This is the same gear used at KidWind Challenges around the U.S. It is easy to build and can be stored in a small space very easily. It has a 48 in x 48 in interior and uses some of the most powerful and affordable fans available. The average maximum wind speed 1 m from the fans is 5 m/s. This kit was primarily created to make it easier and more affordable for teams or locations to engage with the nationwide KidWind wind turbine design competition, the KidWind Challenge.
