Inventors from across the country traveled to Redwood Falls over the weekend to showcase their inventions during the 55th annual Minnesota Inventors Congress invention show. The Grand Prize F. Robert Starr Award was presented to The Skydrill, a tool invented by a Wisconsin pair that quickly, safely and ergonomically installs fasteners to concrete ceilings and screws into drywall ceilings. The 2nd Place winner was the Auto Variable Width Mower, a pull-type offset mower with a remote control variable width offset hitch invented by Melvin and Matt Schueller of Redwood Falls. The People’s Choice Award went to a 4-pound portable home gym that could be used in the potential colonization of Mars. It was invented by a St. Paul resident.
