Tom,
I like the PPP info. Where did you get that 32.4 and for which country and what year. I have been looking at some websites and I am nor finding your probable source.
Using PPP, it is easier to visualize what is meant by being an “aspirational” item (in this case, a cookstove). When someone is able to attain an “aspirational” item, he/she tends to treat it very well because it would not otherwise have
been available. For example, if a program could provide typical Americans with an EV (electric vehicle, such as Tesla or Rivian model) the recipients would watch over it more than their current used car such as my 10+ yr old Pontiac Vibe.
Poor people who can obtain an aspirational TLUD stoves (and an established affordable fuel supply) at a subsidized price are known to use them properly and to have them maintained. And the world can get biochar which is carbon negative,
and that is one of several reasons (including clean burning for better health) that are incentives for us to get these stoves to these millions of impoverished households.

$40 at a purchasing power parity estimated at 32.4 is equal to about $1300 USD.
Geoff, (his message is below, where he wrote: “The Tlud is not a mainly charcoal producing stove that I have seen, perhaps 10% at best.”
I have changed the Subject line so that all responses are focused on what I am presenting.)
The primary purpose of TLUD stoves is for cooking. However, they certainly are also serious producers of charcoal / biochar. And regarding biochar production capabilities and climate impact, micro-gasifier stoves are the ONLY CARBON
NEGATIVE STOVES IN THE WORLD!!! And ESMAP of the World Bank declares TLUDs as the ONLY stove technology that uses dry biomass fuels AND is classified as CLEAN modern advanced cooking along with biogas, alcohol, electric and solar and the fossil fueled stoves
of LPG and Natural Gas. [Please be sure that you understand the significance of this paragraph.]
TLUD stoves can and do make charcoal at about 20% yield by weight. This is shown repeatedly in the natural draft TLUD-ND stoves.
The TLUD-FA stoves with forced air tend to consume a bit more of that charcoal because the air flow is more forceful to put some of the O2 into contact with the char (instead of less forceful mixing of the incoming air with the woodgas
that is coming out of the biomass.)
In forced air TLUDs, the operators also tend to let the fan run a bit longer past the point of completion of pyrolysis, also lowering the char yield slightly.
Because the FA chars are created at slightly higher temperatures (maybe 50 or even 100 deg C higher, but never measured) than 550 or 600 C, there is somewhat less volatile (mobile) matter (less weight) but some improvement of the adsorption
capacity.
And there is one MAJOR social factor attesting to TLUD stoves being serious biochar producers. The commercial value of the charcoal has been clearly proven in the West Bengal projects now with about 100,000 TLUD-ND stoves in daily use,
producing about 80 tonnes of charcoal per day, with approximately 400 persons employed in the charcoal collection business. That char is sold for replacement of coal or traditionally produced charcoal, and is not available for biochar purposes. This brings
approximately US$40/yr of cash income to the women of those households. That is $4,000,000 per year in a small area of West Bengal.
Of special note: An opportunity to transition some of that charcoal from being burned to being sequestered is currently available, involving 6000 households, or 4.8 tonnes/day of potential biochar. And the possible carbon credits for
CO2 REMOVAL (@$100 per tonne) would be a great increase in income. One “packaged project” that is ready for instant implementation (the stoves are already in use with daily charcoal production) needs funding of $400,000 (for only one year) mainly for the
biochar processing and distribution business that is more complicated than just selling the charcoal to be burned. (Please direct any possible “patron” or sponsor or invester to me at psanders@ilstu.edu
for a detailed explanation of low risks and potential rewards.)

Learn why this is important
I have a TLud I bought from Tom in 2007, you light it at the top, it burns down, the air is pumped up from the bottom, so oxygen starved air goes up to the charcoal, producing mainly carbon monoxide (small
amount hydrogen) as the flammable “wood gas” – then usually it is used for cooking directly but sometimes it is piped off to supply a stove elsewhere, – or run a car, although too much tar to run directly.
The Tlud is not a mainly charcoal producing stove that I have seen, perhaps 10% at best..
Geoff.

Dear friends
Thanks a lot for your imputs and sorry for my late answer, (I had an emergency to take my brother to the hospital but he is much better now). Last night I had the first online
meeting with the students explaining general matters about biochar and it’s process and the aim of our work. I will send the your imputs today, thanks a lot!

Luis, List and Kirk, cc Dr. Perez and Kevin
1. Somehow I lost the original of Kirk Harris’ message in this thread (today?) where he said:
Luis,
Your request led me to create the attached flow chart which shows an overall view of the process of interested. It is intended to be a simple outline of the overall process, and is subject to corrections or variations from others on the list. It may help
to give an overall view of where your work fits into the field of pyrolysis of biomass.Respectfully,
Kirk H.
2. Kirk has obtained the most impressive low emissions from TLUD stoves. He is also the only one I know who has a working TLUD for plancha type stoves.. So I urge
you and the four students making contact with Kirk . Like quite a few on this list, his will be pro bono assistance.
3. Kirk: Can you agree with my “red” additions to your nice summary drawing? Anyone disagree?
4. This message mainly to hope that we can hear a lot more about plancha TLUDs. Or maybe there is a good plancha TLUD literature already?
5. For all Central and South American present users of 3-stone fires, I urge a serious look at the “Sun24 3-stone hole stove” developed by Kevin McLean. Three-stone fires
are being used not only because they are zero cost – but because they can support big pots. Most TLUDs can’t match that performance at the needed cost. Another good research option for the “Luis team” and the “Perez team”?.

Hello friends:
I am about to start an thesis work with 4 mechanical engineering graduating engineers from a local university on ENERGY USE from biochar small reactors in El Salvador. Now that our national agriculture school is promoting the use and manufacture of BC with
small units we intend to prove the use of the energy and test to find the most adecuate models for our agricultors.If any one can give advises please do so! remember this is for poor countries, some similar work samples would be ver useful
