<br>
I asked Crispin to name the stoves for which the reported results
are not accurate. And he named one of mine, the Quad 2, which
happens to be about the ONLY stove for which raw data sets have
been made available on the Internet.<br>
<br>
(So, to the the GACC and EPA and others: My request for more
disclosure of raw data set is STILL not satisfied, although we
have received assurances of eventual compliance.)<br>
<br>
Unfortunately, Crispin sent his reply only to me. Perhaps he was
trying to be nice. But I want the cards on the table for ALL
stoves, and it does not matter if one of my stoves is presented in
a bad light (TEMPORARILY). Much of this depends on how the data
is presented, both in calculations and in discussions.<br>
<br>
So much talk and so little reality. <br>
<br>
I am NOT here to defend or condemn stoves that make charcoal (and
they are mainly the TLUD stoves). The reality is that they
exist, and are consistently shown to be among the lowest of
biomass-fueled cookstoves in emissions of CO and PM .<br>
<br>
And they do not require wood as fuel. Those are facts.<br>
<br>
Let the discussions continue. But I am happy that others have
been doing the discussion.<br>

Sorry for not replying. I am on a job in Palo Alto, CA. <br>
<br>
The Quad 2 is one such stove - almost. It uses 1350 g (dry) and
gets (got, anyway) a rating of 636g. <br>
<br>
The new spreadsheet with corrections does a better job. 4.2.1. <br>
<br>
However if a stove were to make 25% char, it would be back in that
category. The UNFCCC uses the CCT 2.0 (names it specifically) and
that uses the energy efficiency, not the fuel efficiency as the
metric to compare on the assumption that stoves do not make char.

Please provide an example. If it is a specific stove, then
name the names and give the data.<br>

<p class="MsoNormal"><span style="color:#1F497D">If someone is
interested in the char, it can be reported – it is in the
raw data set. What Ron is proposing, to reduce the energy
in the fuel consumed by the heat energy available in the
remaining char, is akin to considering the fuel efficiency
to be the energy efficiency which is precisely what
created for us a problem in the first place. </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The energy
value of the char came from somewhere. Consider a stove
that needs 2 tons of biomass per year to operate. If it
produces ¼ of a ton of biomass energy equivalent in the
form of char, fine. Say so. But saying so does not reduce
the two tons of biomass it takes to feed the system. If
you have (as you pointed out) a second stove that can
utilise the charcoal, then that can be viewed as a
‘system’ by all and sundry, but is still does not change
the fact that Stove 1 takes two tons of biomass each year
which is what the reported fuel consumption should be. The
impact of a system is not the same as the impact of a
component of that system. The only debate left is how to
report the fuel consumption and by-products.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">What has been
happening that is wrong, in my view, is that stoves that
actually take off 3 tons of biomass per year have been
getting credit for taking only one ton and proclaimed to
be ‘better’ and ‘more fuel efficient’ than a two-ton
stove. Plainly this is not the case and the test method
has to report the fuel consumption correctly. It is a
problem that the UNFCCC methodology (which measures energy
efficiency) does not handle this well and it is being used
for CDM trades. People are being cheated.</span><o:p></o:p></p>
