Paul Anderson, March, 2009 How many of each major type of cookstoves exist in the developing societies(functioning in 2009)? The attached "draft" Matrix gives you my guesses. Perhaps YOU have additional input. Maybe we should change the Matrix. More columns, more lines. Or do you agree with what content? What I am attempting is to get us all reasonably "on the same page", literally on the same single page. Please look carefully at the two Notes at the bottom. In the general rank ordering, any stove type (or specific stoves within a type) might be shifted one or two columns to the left or right. But the question is, are the notes and orderings reasonably correct? There is no right or wrong, best or worst. By sheer numbers of units, the 3-stove fire is "best." It literally is "the competition to beat" for all of the other stoves. The file is an active MS Word document ( .doc), so you can change it as you please, but please indicate that you have altered it. (I desire neither the glory nor the blame for what you contribute.) It is a very small file and might be distributed with this message.
