Designing a Clean-Burning, High-Efficiency, Dung-Burning Stove: Lessons in cooking with cow patties. (pdf) Mark Witt, Kristina Weyer, David Manning Aprovecho Research Center, ASAT Lab, February 2006
As those of you who were at ETHOS '06 know, Aprovecho has been working on some different dung-burning stoves and presented some promising designs at the conference. A report on the cooking stove designed by Kristina Weyer has just been posted on the REPP Biomass archive. I encourage you to check it out if you are interested in efficiently burning dung.
