Dear Jock,
Thank you for your observations. Useful for discussion and especially
for those getting started, but many seemed a bit dogmatic, that is, too
black and white. Guidance is good; prescription is not so good.
I do take exception with your Item number 2 which says:
2. Basic design must be able to be tuned for multi-fuel capability -
no dependencies on
a single type of feedstock. Jatropha beans, cherry pits, nut shells,
rice hulls, and
densified grass are examples of preferred feed stocks with few, if
any, other uses. Each
feedstock type is likely to require a specific tuning of the system.
From my experiences and observations, the "specific tuning" needed is
basically different stoves for different fuels, especially for the
specialty (non-wood) feedstocks that you name: Jatropha beans, cherry
pits, nut shells, rice hulls, and
densified grass.
ESPECIALLY in places where those feedstocks are sufficiently abundant,
in those places a special stove could be the only one needed, and
therefore not needing to have multi-fuel capabilities.
We should encourage the stove developers to master one specific fuel
very well, and present that stove for evaluation. And not divert to
trying to make that stove also use other fuels.
Basically, stove developers should NOT be discouraged when people say
"but will it also burn fuel X, or Y or Z." Do not worry, there are so
many places in the world with (you name the specific fuel) that there
could be substantial markets in those locations to assure success of a
stove for that specific fuel.

Perhaps these will be of interest to those working on "standards". There is far more to stoves
than simple "performance" characteristics. In the best of all possible worlds, stoves are able to
contribute much more than clean stack gasses. It would be desirable to look at the full spectrum of
potential benefits when evaluating stoves. In the developed economies at least, the saying is that
"benefits sell". The implication is that features are not as powerful a motivations for adoption.
Please remember that this is only a first draft. I did send it to the State
Department in 2011, but they never replied.
I look forward to your thoughts.
Regards,
Jock
