Dear all,<br>
<br>
Rebecca's message (below) merits special attention. Very
informative about a low-cost variation of TLUD stoves. Low cost
because it is with a clay pot support, hollow clay brick for primary
air entry with sand for air control, and one or two tin cans. I
ask Rebecca to tell us the cost of her TLUD stoves. I suspect that
you are under US$ 5. !!!!! (not counting the bench / platform
upon which the stoves are placed for convenient operation height for
those who cook while standing up. But the stove is short enough by
itself to appeal to those who cook while seated or squatting.)<br>
<br>
She is past the stages of proof of concept and the proof of
acceptance-by-cooks. Some fine tuning remains, but this arrangement
is close to ready to be into some (further) pilot studies. <br>
<br>
Notes (that only make sense to those who have viewed Rebecca's
materials):<br>
1. Advantage of a densified fuel ("log pieces"), but wood in a
taller tincan would do the same job and same time. Also your
comment about the male cooks (army) and fuel preparation help point
out that fuel preparation can be a new employment for some unskilled
workers. Fuel type and supply are very important, but almost
always any small complaints can be resolved with a little attention
to fuel handling.<br>
<br>
2. I am not 100% sure of how the top (concentrator) lid is made and
placed onto the fuel can. (I suspect usage of the can opener that
leaves the lip on the lid. Highly economical use of the tin
can.) Instead or alternatively, a separate concentrator lid could
be made from a metal dinnerware plate or improvised easily with a
tinsmith.<br>
<br>
3. Video and photos show TWO stoves that I will call "short one"
(on the left) and "taller one" on the right which is simply raised
on a few bricks. I like the taller one because it has space for and
uses a 3+ inch riser (the second tin can, best seen in the still
photos before it is put into place.)<br>
<br>
4. About that riser, I suggest that you turn it upside down. (or
completely cut out both ends). And consider larger diameter cans
for risers. Experimentation is needed. Please report what you
find to work best (or to not work well).<br>
<br>
5. There are still issues of safety, such as contact / movement of
the very hot single-wall metal pieces (TLUD fuel canister, riser,
etc). Tongs or handles will eventually appear, adding convenience
but increasing the price. This will be adjusted according to the
prefernces of the stove users, and there should NOT be requirements
that these stoves have handles, etc,. thereby delaying the
availability of these stoves to people who could want them.<br>
<br>
6. And an important note about BIOCHAR in Rebecca's configuration:
In the video, they choose to burn the charcoal, which is fine. But
if you want to make biochar, simply remove the fuel canister at the
end of pyrolysis, and insert a second tincan what was already
prepared and ready for use. I think that this stove might have
significant interest in Bangladesh with Mabubul's project. <br>
<br>
Congratulations to Rebecca and her team!! (I suggest that a
condensed version of the video and photo collection might also be
appropriate.)<br>
<br>
Everyone can enjoy reading and seeing their success!!! <br>

<p style="margin:0px"><span style="color:black;font-family:"Arial","sans-serif""> </span></p>
<p style="margin:0px"><span style="color:black;font-family:"Arial","sans-serif"">My female cooks have been using the
Eco-Kalan-C for many years and therefore, are hard to wean
away from the stove that allows them to do all their cooking
effectively and use any type of found fuel year round at
Felipa Beach, Dumaguete City, Negros Island, Philippines.
They dislike cutting or sawing wood into prescribed
lengths for my TLUD stoves. But since male cooks from the
Philippine Army took on some of the cooking and most of the
wood fuel preparations, all my cooks (males and females) now
like to use the TinCan TLUD stove for short time cooking
(within 1 hour) for dishes such as Pancit, Bam-I, soups,
vegetables, small pieces or ground meats "because the TinCan
stove (with dry wood and kerosene as fire starter) is easy to
light, no smoke and fast cooking". For long time cooking
(> 1 hour), they prefer to use the Eco-Kalan-C as adding
fuel when needed is very easy. For frying, my cooks prefer
to use the Eco-Kalan-C because they can adjust the temperature
of the cooking oil easily by taking out or adding fuel to the
fire.</span></p>

<p style="margin:0px"><span style="color:black;font-family:"Arial","sans-serif"">Since I introduced Wilvaco's
(Willamete Valley Company) alder wood briquettes to my cooks
for use in the Eco-Kalan-C and the Eco-Kalan TinCan TLUD
stove (see video and photo albums below), I have noticed
significant increase in their enthusiasm for and enjoyment
from cooking. A fuel can really make a stove tic. The
importance of a good and dry solid fuel motivates me
to participate in finding ways to make wood briquettes
commercially viable for everyone. </span></p>

Rebecca,<br>
<br>
I agree with Ron that it is a very good video. I am very glad to
see your accomplishments.<br>
<br>
My comments are intended to be constructive. <br>
<br>
1. Your fire is a bit high. That indicates some leakage of
primary air. I suspect that it is where the can is sitting on the
hollow brick, not at the primary air entrance that you correctly
cover with sand. Check all around. Put sand around the base of
the metal can. You can also try moist sand. Please let me know
your results (because I am still learning).<br>
<br>
2. Have you experimented with slighly smaller diameter of the
concentrator hole in the top of the metal can?<br>
<br>
3. Also, a few more inches of height between the concentrator top
and the bottom of the pot would allow for more time for more
turbulence. <br>
<br>
4. Additional photos or videos from other angles and of the
individual part would be useful.<br>
<br>
In general, fabulous work. I suspect that you will find further
ways to improve the results. Some ways will be beneficial.
Others will be good but not worth incorporating. <br>
<br>
Looking forward to hearing more of your activities with TLUD
combustion.<br>
<br>
Paul<br>
