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>
