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

Dear Paul
Here is the problem restated slightly better without prejudice re
other biomass:
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.
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 ΒΌ 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.
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.

Crispin
