Dean, More technical babbling: > A great stove would get a higher > score because it is most efficiently changing water to steam. Lots of stoves > loose on both scores. What affects evaporation rate? Only the temperature of the water and the removal of the water vapor from the liquid surface, allowing more water to boil off. Neither one really has to do with the stove. A great stove would get a higher score because it would lose less heat-- which as you say is only related to the real service. If you kept the pot simmering but evaporated NO water, the user's demand would be met, but the (apparent) efficiency would be zero. It seems to me that overfiring would be the biggest cause of efficiency loss. The pot can only absorb so much heat. The rest is lost. What do you people with real-world experience think about that? How do you keep people from overfiring (other than getting Larry to build you a feed magazine?) > A 3 stone fire can be made very well and can score above 20% (Tami may hold > the world's record for BEST THREE STONE FIRE) I don't believe my own numbers, there. :-) Tami - 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.
