[Stoves] CO- and Oxygen-affinity to haemoglobine

[Richard Stanley]

Otto, I think you are onto something. We experienced the same thing in witnessing similar responses from our then super-jock sons when Kibo was a lot less costly and more accessible .... It was about the only time I out-endured them!  

to wit: 
This observation of yours seems to open a new can of worms.
----and Crispin, in a delayed response to your 'canary in the mine shaft' suppositions several days back, maybe we  have to balance what the absolutes tell us in the lab  for the ideal mechanism,  against what the tolerances are  traditionally acquired adaptation mechanisms.  The analogous canary better be from the same household supplying the same miners to the same mine shaft, eh ? 

We're about to host some 55 persons from 10 nations in Africa, here in Arusha, to exchange their experiences and coalesce their thinking regarding issues and options for briquetters. Most all of whom earn their living on the basis  of making selling training researching briquettes and their practical use on the ground.  I hope to find out what they think of the issue and how they handle it and will revert.  Then lets see what the science can make of it for documentation/ replication more widely and consistently.. 

Richard,
 Arusha Tz.
