Dorn will talk about his experience designing and constructing systems on farm-based energy production and conservation. A farmer working a 250-acre, four generation family farm in Lee, New Hampshire, he has designed and constructed systems for small-scale grain and oil seeds processing and biofuel production, worked to select effective cover crops, grains and oilseed for food and energy production, and has developed no-till and low-till equipment to reduce energy use and increase soil health in New Hampshire conditions. As a PhD student at the University of New Hampshire, he is developing biologically-based local food and energy systems designed to return carbon to the soil.
