John Swenson started farming dairy and beef cattle off and on in 1947 on Halo Drive in the town of Kinnickinnic. In the 1970s he added a second farm briefly in the town of River Falls. According to a May 1974 story in the River Falls Journal, Swenson rigged a system to convert cow manure into energy producing methane gas, dubbed “cow-power.” By the late 1970s Swenson and some area farmers promoted the use of corn and grain crops as a fuel source (ethanol). Swenson was motivated by rising foreign oil costs. Submitted photos.
