Pedal-Powered Wheat Thresher

Here's an interesting and short video made by a Hampshire College student in Amherst, Massachusetts. The link was sent to me by the bicycle maker across the street from me, who is a member of an emerging sustainability group in the rural region in which I live. The student designed this small, pedal powered wheat thresher in the hope that tools like his will make it possible for more people to grow grains at the local level, as they now grow flowers and vegetables, to supplement their own food production.
