<p><font size="+1">One thing for sure - nothing get better until
something is actually done at the ground level. Talking and
studies do nothing. AND if the fuel needs be better optimize
(for example) for the air to be cleaner and people refuse to do
it then there is no hope. Next village...<br>

<p><font size="+1">The WBT is best used to determine the
characteristics of the fuel necessary for a specific stove and
not for what it has been used for (ie. best stove). Pack a TLUD
with sawdust and see how long it takes to boil water. Then pack
with large blocks of wood and again time the process. Likely an
optimum somewhere between sawdust and large blocks that work
best with a range of acceptable particle sizes. Particle size
is just one of the many parameters measured. <br>

Whether the cook wants to or can use a particular fuel or a
heavy cast iron pot or a thin plate metal pot and is
comfortable raising or lowering it, we cannot tell without
getting groudlevel intelligence. Theories are only an easy
way out. <br>
<br>
Science would first strive to identify the problem, then
understand what variables can be controlled in what contexts
and how, THEN move, if needed, to the IWA exercise. <br>
<br>
Putting cart before the horse, over and over again, is a
proof of insanity . <br>

I'm thinking (as Tami suggests) that a stove works best
with a good active combustion. We should not try to slow
the flame to lower the Power. Perhaps that can be done at
Box-4. Use a heavy cast iron pot or a thin plate metal pot
depending on the power wanted to get into the task. Lift
the pot higher than optimum to lower Power or add more
water. <br>

Even in a narrow geography of one agroclimatic zone,
the variations in fuel quality and prices, stove use
patterns, may vary quite a bit and you may not find
the control over variables that you want. (Except,
say, you had a processed fuel that can be delivered
economically and reliably.) <br>

Fuel quality and stove use patterns will vary. The purpose
of what i suggest and what others have left unmentioned
when using processed fuel in their stove tests. And it is
true that we may not find the control over variables that
we want - That's science. At least we will know precisely
what the problem is. <br>

<p><font size="+1">There may be a lot more
things we can determine once we get
control of the six variables And that will
depend on how much control we can get.
Even the discussion Paul and Crispin are
having as the CO and CO2 reactions will
need control of the biomass properties and
packing before answers (with help with
using helium surrogate) is determined.
And we must be using real wild biomass
prepared for the combustion chamber or the
results will mean nothing when the stove
and test results are delivered to the
receiving site. <br>
