Kevin,<br>
<br>
Thanks for the spreadsheet. This is an interesting situation where
calculated numbers are not matching with some human activities about
the value of charcoal.<br>
<br>
This discussion is only with the Biochar group, so I am adding the
Stoves Listserv and attaching the spreadsheet.<br>
<br>
Notes;<br>
<br>
The use of BTU/LB in columns H and I should be in the green
(calculated) values and the corresponding metric units (which you
provide) should be the yellow variables that can be entered.
Please.<br>
<br>
I notice that changes in the Value of unburned char/kg (C23 ) is
essentially linked to the cost of fuel wood (C5) , and therefore
virtually dictate the conclusion of carbon credit pricing needed
(C28 ). So, the price stays quite high.<br>
<br>
****************<br>
A. Consider the case of the cook who has no real use for the char,
which means that the cost of fuel is 100% allocated to the cooking,
and the resultant char has zero value. To that cook there is no
trade-off about char being used for cooking other meals. Selling
the char is "pure profit", whether it is a calculated value of
$0.16/kg (as in C26) or merely $0.12/kg as in Deganga, India, or
only $0.08/kg which is still better than nothing.<br>
<br>
B. Current "traditional" cooking with charcoal that is produced by
generally inefficient "traditional" char-making methods would have a
char yield (C6) of between 10% (burning too much to ash) and 25%
(leaving volatiles in the char, or even some incomplete
pyrolysis/torrification). <br>
<br>
C. But for those people who produce traditional char, the "cost of
fuel wood" (C5) could be as low as zero (illegal cutting or
destructive cutting) or some notional value of the time spent to
make the charcoal. <br>
<br>
Others need to comment also. <br>

that is what Kevin actually said. <br>

Then to Kevin: Actually, it the char yield is

25% or 30%), then the number becomes <span

73.10 per tonne of CO2 equivalent. </span><br>
<br>
To all: As reported in the Deganga Case Study
(page 4, 3rd paragraph), in that case study
the people were actually paying US$0.075 per
kg of firewood. And they burn 3 to 4 kg per
day (which is less than half of baseline fuel
consumption). Note: 4 kg of firewood at 20%
char yield would be about 0.8 kg of char per
day (matches the measured quantities of char
purchased from the households). <br>
<br>
And they were receiving payment of $0.12 per
kg of char via the "Earn while you cook"
arrangements (page 4, second paragraph from
the bottom of the page), which would be $0.04
per 0.3 kg (just citing Kevin's initial number
for some comparison) or $0.024 per 0.2 kg (the
approximate actual char production per day of
cooking.).<br>
<br>
Can we use some of these above numbers and
send a revised statement, please? <br>

why are the people so delighted with the

<br>
Thank you for
the input.<br>
<br>
World figures
are that about
3 billion
persons have
meals prepared
on solid fuel
(mostly
biomass).
Family size
(especially
HOUSEHOLD
size,
referring to
the number of
people who eat
together)
should be 5 or
6, which
would put the
number of
households
between 600
million and
500 million.
Those are the
numbers that I
prefer to use.<br>
<br>
I agree with
nearly a kilo
of char
produced per
day per TLUD
stove
(confirmed in
Deganga,
India,
study). 365
days would
yield about a
third of on
ton of char
per
household. 3
household
become a
ton/yr.
30,000 HH
would be
10,000 tons.
300,000,000 HH
(about half of
the needed
cookstoves)
would be
100,000,000
tons.<br>
<br>
So it would
take 10 years
to reach one
GIGA ton,
which is
1,000,000,000
tons.
(Please check
my math.)<br>
<br>
In the
Drawdown
project, the
time period is
2020 to2050,
which is 3
decade, or
"potentially"
3 gigatons of
char
sequestration.<br>
<br>
3 GT is only
1/5th of the
GT calculated
for ALL
cookstoves,
and over 3
times more
that what was
calcualted for
ALL biochar by
2050. Clearly
there is more
to the
drawdown
calculations
than the
simple numbers
above.<br>

Stovers and

<br>
The financial
part of
advancing the
TLUD stove
situation
(IMO) keeps
coming back to
the value of
carbon offsets
generated.
But that topic
is too thinly
related to the
purpose of the
Stoves
Listserv or
the Biochar
Listserve.
So I will
sending this
message. <br>
<br>
The <u>stoves-related
carbon-issues
discussion </u>(generating
carbon
credits,
global
drawdown, etc)
need
discussion.
So I request
some
assistance to
find where
this can be
discussed.
Does such a
place already
exist?<br>
<br>
Also, who
among us want
to be into
that OTHER
discussion?
Paul, Ron, and
who else?<br>
