John designs and builds innovative small-farm machinery that addresses some of the most difficult agricultural problems associated with peak oil. He will demonstrate the Thresher-Winnower design, a miniature combine that threshes grains on a neighborhood scale. The first prototype was built 25 years ago to process grain he and his wife grew on their farm, and the idea was resurrected a few years ago when interest in local food production began to grow throughout the country. The complete machine weighs 60 pounds and will thresh and winnow up to 20 pounds of clean grain per hour. The Thresher-Winnower cleans beans as well.
