[Stoves] Very interesting Stove (Thailand?)

Roberto and all,

I agree that it is an interesting video about a somewhat different 
variation of TLUD stoves.    To save all some time, I give you these notes:

1.  Yes, probably Thailand, but not clearly indicated.   All dialog and 
text could not be understood, except that it was filmed at a research 
center for ag machinery.

2.  24 minutes is LOOONG.   I suggest you load it and then see these 
selections:

3.   Gets interesting about the details of the stove in minutes 6 
through 10.   You will see a large square metal tin and two concentric 
cylinders.   VERY Interesting use of 2 crossing rods at minute 8:30 to 
space the three containers and to support the grate.

4.  Minutes 13:00 to 17+ show the use of insulation (seems to be ash 
from rice husks) between the outer square can and the next cylinder, 
including how to seal it off (wet ash with rice husks).

5.  There is no attempt to limit the primary air.    It is free flowing 
all the time.   [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. ]

6.  Secondary air enters via several (4 or 6, I think) sets of three 
holes (arranged vertically about 2 cm apart)  in the innermost cylinder 
(the fuel chamber).   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.

7.   Near the end (about minutes 20 and later) you can see the stove in 
operation.   Seems to work nicely.   Apart from measuring the flame 
temperature there is not testing shown in the video.

8.  If anyone has access to Thai speakers, please confirm or correct the 
above message.

Thank you to Roberto (who is in Chile) for finding this and calling it 
to our attention.   I will consider how to present my comments and the 
video link at my drtlud.com website.
