Aerial wind-sensing device that determines optimal locations for wind turbines


The "Windamajig," the invention of the Great River School InvenTeam, provides a user-friendly solution for small business owners and homeowners looking to install a wind turbine. It employs multiple wind-velocity measuring sensors suspended from a balloon. It will measure wind speeds in a specific location with accuracy of up to 2 mph and at multiple elevations simultaneously. The InvenTeam aims to keep the manufacturing costs low, which will result in greater affordability for the small-scale, wind-energy operator who can use it to assess wind-energy potential.

The InvenTeam received a 2009 Continuation Grant.
