Ron,  you keep repeating: We have no idea yet on why simple rocks and extra grates are doing so much.   (Anyone have an idea why?  My next message more on that)
And I have provided an answer to that numerous time and sent the link to the AProvcho article on the importance of the initial load: 
You can save an enormous amount of charcoal if you limit the amount that people load into a stove. The Zambian brazier is completely overpowered as people load it to the brim. Adding a grate and filling the existing volume with stones prevents that people can land the same amount of charcoal as the stones displace the charcoal. 
Same as putting a brick in the tank for the toilet flush saves water, as it fills part of the volume. 

I did testing on the Zambian brazier today (it was loaded with 900 g of charcoal as people tend to fill it up) , and we cooked the same meal with less than half the charcoal on any of the other stoves where we only loaded with an initial 310-350 g of charcoal 

That is my answer
Christa

Bernhard and list,  cc Kevin

	1.  Kevin responded to your increasing CO comment (below) - saying CO not yet measured.   (This following Kevin’s message re adding rocks and an extra grate to the Zambian  (char-burning) “Mbaula” - giving maybe 40% fuel saving.
	
	2.  I guess that the reverse is likely: less CO.   My reason is the horrible production of CO - which drives down efficiency.  Kevin’s efficiency is going up - not down

	3.  This is mainly to hope that we can find someone (in nGermany?) to make the measurement.  Important because Kevin is achieving a huge tree-saving result at almost no cost.

	4.  We have no idea yet on why simple rocks and extra grates are doing so much.   (Anyone have an idea why?  My next message more on that)

Ps - Thanks for all you have done for solar cookers (I own one of your 1 meter parabolic designs).  Your BABAMOTO stove (see below) looks quite interesting.  I was happier to read your piece on char-making stoves at:
