<p class="MsoNormal"><span style="COLOR: #1f497d">If someone is interested
in the char, it can be reported. What Ron is proposing, to add that heat
energy available in the char back into the mix, is akin to considering the
energy efficiency to be the fuel efficiency which is precisely what
created for us a problem in the first place. </span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d"></span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d">The energy value of the
char came from somewhere. Consider a stove that takes 2 tons of forest per
year. If it produces ¼ of a ton of forest’s worth of energy in the form of
char, fine. Say so. But saying so does not reduce the two tons of forest
it takes. 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 forest
each year which is what the reported fuel consumption should be. No smoke
and mirrors.</span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d"></span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d">Burying the char as a soil
amendment instead of burning it merely takes us back to the two tons of
forest per year draw-down and returns it to the environment in an
(apparently) inert, solid form.</span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d"></span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d">What has been happening
that is wrong, in my view, is that stoves that take off 3 tons of forest
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 does
not handle this well because it is being used for CDM
trades.</span></p>

<div class="moz-cite-prefix">Ron, Crispin, Jim and all,<br><br>One
stumbling point is the difference between the words
Fuel and Energy.
We cook with fuels. We cook with energy. But a
piece (1 kg) of wood (fuel) can deliver 16 MJ of energy if burned to ash
or it can deliver (example) 11 MJ of energy PLUS charcoal that
represents 5 MJ of energy. <br><br>The piece of wood is
totally changed in both cases. But in the second case, part
of that wood has been transformed into charcoal, which is certainly not
wood. Wood consumed is 1 kg. Energy
consumed is 11 MJ (with charcoal left over). Two very
different results to be reported.<br><br>And then there is the case of
one kg of agricultural "refuse" that is 16 MJ if consumed totally, or 11
MJ plus charcoal if pyrolyzed, and in NEITHER case was there any
consumption of wood. Where deforestation is an issue, stoves
that can use (easily use) agricultural refuse need to be distinguished
from the wood burners. </div>
