[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.
