    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>
