[Stoves] Very interesting Stove (Thailand?)

[Ronal W. Larson]

Paul  cc List and Michael:

	1.  I thought you had a good summary.

	2.  I’d like to know more about the insulation - a portion seemed combustible. but apparently not.

	3.  Also an interesting set of pots.  Seemed the main cooking utensils sat inside a wok.  Heat transfer via conduction; kept pot clean, but no chance for a skirt.

	4.  I was surprised that there seemed to be no careful placement of fuel.
	
	5.  I could get a translation of the 41 comments - but saw nothing useful - except there seemed to be a University connection.

[IMO, this aspect could be improved, and it seems that the developers were rather on their own about the design of the stove.   But we know that new experiments and designs can bring progress, and are glad to see this TLUD development. ]

The sets of holes are about 5 (?) cm below the top of the fuel cylinder, therefore giving some drafting.   Otherwise, there is no riser on the unit.   And not concentrator disk.
