[excerpted from the Michigan Daily]
Joe Trumpey, a professor in the School of Art & Design and the School of Natural Resources, built his home in Grass Lake, Michigan with his own two hands. Using straw bales as the base and a homemade adobe mixture as an outer coating, he has been constructing the 2,200 square foot residence for the past several years with help from his wife, two daughters and the occasional volunteer group from the University. He has 40 acres of forests and pastures hiding cattle, a flock of sheep and a 4KWatt solar array on a dual axis tracker mounted on a 25′ pole. He and his family live in this home completely off the grid: they haven’t burned a drop of fossil fuel to heat the house and water the past 3 winters. They were recently named homesteaders of the year: http://www.motherearthnews.com/homesteading-and-livestock/self-reliance/self-reliant-living-homesteaders-of-the-year-2015-zm0z15aszkon.aspx
His talk will discuss the sustainability issues related to the house, farming, and energy storage.
