<br>
I am excited by your work with the new material. It seems very
well suited for TLUD stoves as well as other types. Count me in
for being of assistance and encouraging needed research to get
production (even experimental) underway.<br>

Any Stover concerned about the materials of stoves should read the

This list obviously can’t be supporting single
companies, and I certainly don’t know enough about
yours to want this to be an endorsement. However, you
do seem to have a production approach that is very
promising and presumably you can eventually supply
materials to list members. Even if that is not the
case, you have plenty of new stove design ideas that I
want to recommend all serious stove designers to see
what Thomas has introduced us to today.</div>

<div>>>To see this new technology be of benefit to the
people of developing nations I need to demonstrate the
Ksial material and the abilty to produce stoves in mini
factories. There is a pressing need to address this
situation and my efforts are split between stove
development and working to financially support my family.
Whilst there are several avenues of funding from the GACC,
World Bank and the Asian Development Bank these programs
are only open to companies trading in the field of clean
cookstoves. The funding I am seeking is to help me bridge
this gap and become a trading company which can then apply
for the GACC Spark Fund etc. </div>

seems likely that the main new key feature of your

explain more on when that will be available from you.
Is it proprietary? What is behind this most unusual

</div>
</blockquote>
<div><br>
</div>
<div>>>The name Ksial is inspired by the chemical
composition of the material. It is a proprietary material
I have researched and developed and is not yet available
for sale. It is not particularly easy to use so may never
really be available as a one bag product like portland
cement. As per point 2 and 3 I may have appeared to have
made a commercial posting on the stoves list it was more
of sharing my efforts in the cookstoves field. I will
certainly try and help out others with their stove designs
and prototypes but please remember that I am making these
efforts with a full time non stove related job and a young
family to support.</div>

<div><span style="white-space:pre-wrap"> </span>5. I
found a single 2013 unanswered question on whether you
were planning a char-making stove. This is the only
type of interest to me. The reason is one you have
yourself given in the “story” part of your site, where
you say: </div>
<div><span style="white-space:pre-wrap"> </span> <i>"<span
style="background-color:rgb(255,255,255);color:rgb(20,20,18);font-family:'Source

to provide one million stoves will make a huge
difference with a CO2e reduction in the order of
one million to three million tonnes every year."</span></i></div>
<div>That is a carbon neutral number - interesting, but
nowhere near the much larger carbon negative number if
you had a char-making version (which should be
cheaper and easier to make with your nice mold
approach). And you could still have about the same
carbon neutral number you give - and that is obviously
important to you.</div>
</div>
</blockquote>
<div><br>
</div>
<div>>>I have made a combination stove that burns wood
and produces char. I do find a flame out problem when
trying to run on producer gas only and use the wood or
charcoal to ignite and keep alight the producer gas flame.
I am not sure if is a common problem with steel stoves but
once the flame is out the gassifer becomes a smoke
machine! I really don't want to get into the char debate,
especially having presented a simple Charcoal stove. I do
believe that char stoves present a huge potential to
sequester carbon, provide agriculture benefits and can
very clean burning. </div>

<div><span style="white-space:pre-wrap"> </span>6. I
have talked to a few list members about what I
consider most interesting and will test as soon as
some promised material is received. Thomas used the
term “basalt” - and showed some soft (like cotton
candy) “rock wool”. I hope we can have a discussion
of this general class of high temp insulative
material. I am looking (as I think Thomas is) at a
more rigid variety.</div>
</div>
</blockquote>
<div><br>
</div>
<div>>>Basalt is volcanic rock. Rock wool is an
insulation made from basalt fibers and blast furnace slag.
It is more economical than ceramic wool type materials. It
was used in some of my prototypes which used a thin wall
(5mm) Ksial combustion chamber in a steel can outer. It
was a variation on the popular tin can rocket stove that I
am sure a lot of "stovers" started with. </div>
<div><br>
</div>
<div>The rigid, structural insulation of my one piece
designs is perlite which is used as an aggregate with a
Ksial binder. Apart from providing strength to completed
stove this overcomes the problem of loose perlite becoming
very powdery and leaking from the stove. </div>

Your design (CO5??) with a sleeve in a night-time WBT
was very interesting. Can you share any numerical
data for that - and compare to that without a sleeve?
The pot was interesting (new to me) as well. I hope
we can see/hear more of that - with such pots
appearing on the market. I was surprised that you had
such a tight fit.</div>
</div>
</blockquote>
<div><br>
</div>
<div>>>The design of the pot is most interesting. You
could call the Unity Stove open source contribution to
cookstove development. It is something that a University
could experiment with and document the efficiencies. Apart
from increasing the surface area the dimpled form allows
the pot to have intimate contact with the side of the
stove in several places. In operation the combustion gases
are heating the side walls of the stove as well as the
pot. This design allows some of that heat to flow from the
side walls to the pot as the pot is relatively low
temperature (full of water) Converting a spun aluminium
pot to a Unity pot is easy, a block of wood and a hammer
and 10 minutes of hammering. </div>
<div><br>
</div>
<div>The sleeve or pot skirt is part of the stove design, it
does not come off. If the wok, which sits on top of the
stove, is used to boil water the observed efficiency is
lower.</div>

<div><span style="white-space:pre-wrap"> </span>8. I
hope to stamp out all char-consuming stoves however.
That char is too valuable for atmospheric and soil
reasons to be burnt. I did like though that you made
your own char - and the tandoor video showed how that
was happening. With a char-making stove, it would be
much easier to obtain that char - and more of it.</div>
</div>
</blockquote>
<div><br>
</div>
<div>>>Actually the char comes from our house heating
stove, which is an old Fisher Stove Mama Bear retrofitted
with stainless steel baffles (yes they came to Australia
as well) The tandoor stove could well be used to produce
char if I tapped off the producer gas or treated is a big
TLUD, it is really just a well insulated retort. I should
look into that.</div>

<div>Again - Thomas - thanks for one of the most
interesting stove messages we have ever had on this

I should add that you have made excellent use of
