To know the actual power as a calculated number MIGHT not be so
important. But conversations and comparisons need to be in the
right ballpark about how powerful a stove is. <br>
<br>
In the case of the "tea-test", the info in the 6 boxes needs to be
the same except for one variable that is being studied. And
there will be some level of fire power that is to be held constant
(unless that is the variable being studied). Also, when another
variable is changed, the impact might be seen in the "power level"
that is expressed as how much faster or slower the pot came to
boil (therefore the use of the clock/watch.).<br>

Your USE of the 6-box system is the clearest explanation that
I have read. Your comments put it into practical
perspective.<br>
<br>
Philip Lloyd's comment about wanting to know the thermal power
is correct. And you can overcome that with a watch that
shows seconds. Record the time-to-boil. Record it in Box 5
or 6, right? <br>
<br>
And it certainly could be useful for Michael's needs. Or for
teaching science under a tree in rural Africa.<br>
<br>
**** joke: Michael teaches at the college. but if he was
studying there, this could become known as student's
tea-test (Ouch!) ***<br>

<p><font size="+1">This is a good example where the 6-Box
system would be useful. <br>
</font></p>
<p><font size="+1">Set up the system so it makes good tea.
The process is to control the variables and modify one
at a time to improve the process. There are lots of
steps you can do but would take some time, test methods
and a little equipment. All simple but not good at this
time. Once you have a good fuel, good technique, and can
produce a good cup of tea I suggest the following:</font></p>
<p><font size="+1">Box-1) Observe the fuel for size,
moisture, cleanliness etc. <br>
</font></p>
<p><font size="+1">Box - 2: Record the process loading the
combustion chamber.</font></p>
<p><font size="+1">Box- 3: Record the combustion chamber;
stove model etc.</font></p>
<p><font size="+1">Box-4: Establish info regarding the
utensils used; metal, size, heavy-light etc.</font></p>
<p><font size="+1">Box-5: Record the process; stirring,
amount of water, amount of tea, sugar added etc.</font></p>
<p><font size="+1">Box-6: Determine a good repeatable
Completion Point. Perhaps water just starts to boil or i
can hold my hand on the side of the pot for just one
second.</font></p>
<p><font size="+1">You need to know what an improvement
would look like for you. Quicker tea but not care of
amount of fuel. Save on fuel, walk away with less
manipulation, air quality, amount of char left, quality
of char produced, etc. Whats important is what the end
user decides important. <br>
</font></p>
<p><font size="+1"> <br>
</font></p>
<p><font size="+1">Now all steps are controlled and should
be repeatable. You can change one Box at a time and see
if that improves the process. Use dryer wood or stir
more frequently. Use a lighter pot or less water. Add
wood more frequent in smaller quantities - try to get
the best conditions. <br>
</font></p>
<p><font size="+1">Because no-one else is doing the same
system you will not be able to compare to other systems.
But you might be able to improve your own. And there are
lots of measurements for the fuel that can be made (not
described here) but use simple test methods and no need
for a real lab. Perhaps just some basic equipment. <br>
