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:<br>
<br>
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.<br>
<br>
2. 24 minutes is LOOONG. I suggest you load it and then see
these selections:<br>
<br>
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.<br>
<br>
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).<br>
<br>
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. ] <br>
<br>
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.<br>
<br>
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. <br>
<br>
8. If anyone has access to Thai speakers, please confirm or
correct the above message. <br>
<br>
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 <a href="http://drtlud.com">drtlud.com</a> website.<br>
