Change: Design and validate a radically simple, reliable, and inexpensive millet threshing (and ideally winnowing) machine, appropriate for small (<~ 1 acre) farmers. Target customersare primarily women who currently thresh and winnow small quantities of millet for their daily use or to sell a small surplus. Their capital   View changes from previous version.
