Dear Friends, Don O'Neal, who manages the HELPS griddle stove project in Guatemala, reminds me that families need to be matched for comparison in wood use studies. He points out the following: >Dean: > > May I throw in a comment or two. I tried comparing families wood >consumption some with and some without stoves. The problem that I >experienced ( and caused me to stop) was that there are family-size >variations and wood-conservation-techniques variations that swamped what I >was trying to study. > >We teach wood conservation techniques during stove training and find that >those who practice these techniques find it makes a bigger difference in >'real' efficiency than small differences in 'stove' efficiency. But if you >could get the same family and same cook to cook both ways for a period of >time you might derive a beneficial result. > - Stoves List Archives and Website: http://www.crest.org/discussion/stoves/200202/ http://crest.org/discussiongroups/resources/stoves/ (Under construction) http://www.ikweb.com/enuff/public_html/Stoves.html (Original) Stoves List Moderators: Ron Larson, ronallarson@qwest.net Alex English, english@adan.kingston.net Elsen L.
