Thanks Andrew. I hear you. I cannot afford the time to follow another list and there is little I could contribute at this time.
I have continuously in mind the economics of fuel for stoves and the characteristics of char that might be a goal. As you know the responses are pretty thin on both counts. I repeat my invitation to any/everyone to have a look at some of the stove tests at the New Dawn Engineering Library and comment on them. The type of testing is not encountered when doing cooking or water boiling tests so it may give everyone new insights into what is actually coming out of a stove and when. Tami was testing in Honduras and reported that 85% of the PM was emitted in the first 5 minutes. The tests I posted (only 4) show how this was dealt with: attacking the ignition problem as the main issue, not the later stages of the burn.
