You and I discussed this before, and you have changed your position.<br>
<br>
Let's just agree to disagree. I am finished with this
discussion.<br>

are looking for a metric that communicates the benefits of a

guys have said that repeatedly. So…report the char.
Characterise it. It is a benefit. It does not alter the fuel

also the cooking efficiency if it is a cooking stove.

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">I
am very clear that Ron wants it to result in a ‘higher
number’ so the energy efficiency, in terms of how much fuel
is needed to operate the stove, appears better than it is. I
have understood that from the start. You cannot mis-report
the fuel consumption. You can report the fuel consumption
and also the char production. But you can’t weasel the
energy in the char into a better fuel consumption number,
because making char does not reduce the amount of fuel
consumed. That is not complicated.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:windowtext">></span>As

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">Taken
into account to report what? The fuel consumption? You have
agreed it is not the same as ‘fuel’. Fine. Then it is not
going to raise the fuel efficiency. Now what? What are you
going to call this char energy? I have proposed calling it
the char energy retention efficiency (CERE) so that a stove
which produces more char per input of fuel while maintaining
the cooking ability gets rewarded with a higher CERE number.
If it also cooks better it can have a higher cooking
efficiency.<o:p></o:p></span></p>

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">If
it cooks better should it get a higher CERE number? Of
course not. The char production didn’t increase.

<p class="MsoNormal"><br>
<span style="color:windowtext">></span>And you said that I
would agree that knowing "heat transfer efficiency" woud not
be helpful to me. I disagree. It is certainly useful to
know how well a stove gets the heat transferred into the pot.<span

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">I
said it would not help you find a metric that reports the
efficiency of char production. Of course the HTE is helpful,
but not to regulators or buyers, any more than the
efficiency of second gear in a car. It is the whole package
that delivers the fuel efficiency number.<o:p></o:p></span></p>

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">I
also suggest you could report the market value of the input
fuel and the output char. If the ratio of char/wood is
greater than 1, it is a money maker. That is a highly
contextual market value but still, it would drive sales if
there is a benefit.

it a name, ask that it be reported. How about ‘Energy
Benefit’? That could be used to report space heating as well
because some stoves do that. For the on in the example the
Energy Benefit would be 75%, and the breakdown of that would
follow: 12.5/25/37.5<o:p></o:p></span></p>

gives the buyer a clear indication of what they are getting.
Maybe they want to see that middle number a lot higher and
are not worried about cooking (cooking efficiency is not
important in Kyrgyzstan – the heat tea water only, most of
the time.)<o:p></o:p></span></p>
