[Stoves] forced draft (Re: A Karve 13 August)

Cecil, Nikhil, list et al:

	This is the first time I have understood Cecil’s interview methodology, where he says below his (and Crispin’s) method was: “..to minimally tweak 
traditional stoves ..”   This obviously is biased against TLUDs and charcoal - making.  I contend this also underestimates the intelligence and desires of the rural cook.

	I wonder if any other person doing stove questionnaires or knows of their existence has ever seen one that asked any question pertinent to TLUDs?  Examples of questions I would like to see asked (and never have seen) are:

	1.  Would you consider a stove that could be paid off in months from the charcoal you could make with it?
	2.  How would you rank the importance of using a stove that you could leave unattended for an hour?
	3.  Would you consider buying a stove that could use very small pieces of fuel?
	4.  Would a stove that helped address global warming be important to you?
	5.  Would you consider a stove whose charcoal output could possibly double the productivity of your garden?
	
I assume questions are regularly asked about emissions - so TLUDs might have a small consumer advantage there.  But one would have to know the relative advantage - such as asking about a biomass cook stove that could be cleaner than a kerosene stove.  I doubt such health-related questions have been asked.

	So I ask Cecil (who I have known for decades) if he has ever asked any stove questions like these above - or ever seen any such?   What answers would he expect?   What would Nikhil  (who I have also communicated with decades ago) think would be the answers?

We are forced to fight the battle of armgeddon simply to decide what parameters and assessment methodologies can be trusted to guide the development of simple $10 improved stoves for the 1/3 of humankind at the bottom of the world scrum.

The mrta-culture between the stove and the plasma of knowledge and symbols might be referred to as the human factors which mediate the relationship between stove users and their stoves. OK. That is where I choose to start. Other professional stovers have other skills, interests and points of intervention.

If we are to make real progress in the small stove/biomass fuel economy  it is necessary for all role players to take deep breaths, cool off, depoliticize, speak kindly to colleagues, and grow the common ground that unites us all in our quest for an infinite series of apprpriate "good" little cooking and heating stoves.

(There will always be premature mortality; the GBD people will find something else to blame it on, for example boredom with academia.)
