Change: Later we made this diagram showing 3 different paths we could take to isolate clean grain. We initially thought the middle path (2) would be most achievable. Breaking up grain from floret can be thought of as "endothermic" (or more technically correct, "endergonic")-- it doesn't View changes from previous version. (Word count: 474)

Change: Corn sheller concept.In conclusion, both threshing and winnowing millet requires energy input (which is of limited supply for our goal of a human-powered system). Applying this abstract thermodynamic analysis has constrained the space within which we can hope to find solutions. Q.E.D. Home Previous Next Contact Us View changes from previous version.
