	I will be pushing for adding to the standards something on reporting on saved time during cooking and making money through sale of char.

	Yes  -  I have had the pleasure of talking a good bit with Kirk - ever since the/your last Aprovecho stove camp.  

	Thanks to you and Aprovecho for the considerable support you have given Kirk.

	Two chief innovations in Kirk’s work, that I hope others will start looking at including in their designs:  
	a)  getting swirl (more than half a revolution) and 
	b)  getting secondary air to both the outside and inside of the main combustion zone.  

Still has a diffusion flame, but much shorter because of turbulence.  Can save a lot in stove height, and therefore cost.

This is to hope that you can assure some ETHOS dialog on how it compares to the DoE and GACC efforts.  I recommend all read at least the last few pages of that report - found at:

I found the report to be well written by knowledgeable people,  However, they apparently failed to have any authors who have been investigating char-making stoves - the topic of about half the messages on this list.  I see a little recognition under the term “fans” - but hope others more familiar with this WHO report can explain more on this lapse.  (And Aprovecho was not well enough represented either in that WHO study.)

>> As many of you know, the yearly ETHOS conference (January 23-25) is located at NorthWest University in Kirkland, Washington. ETHOS was created 14 years ago to bring the lab and field closer together, to give field and lab workers a place to exchange knowledge and ideas. 
>> 
>> This is an especially interesting year! The Department of Energy funded six projects to research and create 'Tier 4' stoves: biomass cookstoves that protect human health and address climate change. These projects will report their progress and 'Tier 4' stoves will be displayed and lit in the courtyard!
>> 
>> The Global Alliance has also accomplished so many things this year, just recently having fund raised 700 million dollars for stove projects. ETHOS provides a space for interacting and asking questions. What is happening with the ISO standards? What do the new WHO guidelines mean for stove projects?
