      Philip wrote:
      <blockquote type="cite"><span
style="font-family:"Calibri","sans-serif";color:#1F497D">I

      It is precisely because things are (or might be) wrong that we
      need this time for discussion, even if it is a form of arguing.  
      To not press for clarification (and a possible reversal) of what
      Dean is so staunchly defending would be to yield to the status quo
      of the testing procedures.   <br>
      <br>
      Crispin has been rather lonely as the outspoken critic of the
      status quo WBT.   It is interesting to hear such a solid support
      by you (Philip).    It would be good to hear from others who agree
      with Crispin's comment: <br>
      <blockquote type="cite"><span
style="font-family:"Calibri","sans-serif";color:#1F497D">The

          variables selected [for Low Power testing] are inappropriately
          chosen. .... </span></blockquote>
      But Crispin and you give an incorrect comment when saying:<br>
      <blockquote type="cite"><span
style="font-family:"Calibri","sans-serif";color:#1F497D">.... 
          We have to move on.” </span></blockquote>
      The time is NOW to keep this discussion going until there is
      resolution.   It might take a while, but as I see it, there are at
      least two CAMPS or lines of thinking about the Low Power
      measurements in the stove testing.   Dean seems to present much of
      the thinking found in the USA, with some (but probably not all)
      supporters in the GACC and EPA.   Crispin suggests that at least
      some other countries and agencies are supportive of his line of
      reasoning (China, Indonesia, South Africa, World Bank).   But
      certainly that also is not 100% locked in.    <br>
      <br>
      Perhaps there is a totally different method or two.   Perhaps the
      current method and an alternative are BOTH meaningful.   But I
      doubt that.   I am a stove designer, not an equation-using
      physical-chemical scientist.   So I will win when whichever
      testing methodology is found to be correct.   And I am VERY
      CONCERNED that in 2015 we still need this discussion and debate.  
      But it must be resolved!!!!!!!!!!!<br>
      <br>
      Dean commented (and I think I did not take it out of context):<br>
      <blockquote type="cite">... the new approaches are forged by
        consensus.</blockquote>
      "Consensus" will prevail (and there will be some who will never
      join the consensus).   But consensus is not to be based on
      democratic votes or even a slight majority number of nations
      adopting some set of standards.   What must prevail is the SCIENCE
      associated with the testing procedures.   <br>
      <br>
      We should not be here trying to get votes like politicians.   We
      need to be hear sound scientific arguments.   So, my requests are:<br>
      <br>
      Philip, (and others) please help explain what is incorrect with
      the Low Power testing measurements and calculations.   Most
      specifically, the use of a variable called "amount of water boiled
      away during simmering" seems to be in question.  (also expressed
      as weight of water in pot at end of simmering time).<br>
      <br>
      Dean, (and others) please help explain how the boiling away of
      water during simmer time <u>has meaning in the calculations</u>
      .   We understand that evaporated water represents heat energy
      that exits the system.   But the system is about maintaining a
      boiling point (or slightly below), and that task is accomplished
      whether the evaporation is of 0 or 100 or 300 or 500 or more grams
      of water.   <br>
      <br>
      AND we know the amount of fuel that was consumed.   What is
      important is the fuel consumption, and we do not need "weight of
      evaporated water " to know the fuel consumption.   There is no
      "work" in simmering except to keep the water in the pot from going
      below the minimum allowed temperature.   And the water temperature
      cannot possibly go above the boiling point (unless in a
      pressurized vessel, which is not an allowed consideration).<br>
      <br>
      To all:  Please help us all to see the formulae (three of them,
      for efficiency, CO and PM) that are in the current version of the
      testing protocol.   The document is public and on the Internet.  
      Please help us find the right specific pages.    I will not
      pretend to understand such formulae, but with help, I want to boil
      it down to the issue of the evaporated water.  Does it matter?  
      Should it matter?<br>
      <br>
      I am most focused on the formula for efficiency, but all three
      with survive or fall together with the understanding of the impact
      of the amount of water that is evaporated during simmering.<br>
      <br>
      This is NOT the time to turn away from this discussion.  <br>

                              Tom H.,         and to all who are
                              interested in proper testing of stoves.<br>
                              <br>
                              Your reply about your experiences is
                              helpful.   Sounds like you had qualified
                              testing center do the testing, in
                              accordance with the procedures that
                              Crispin is questioning.   Please send to
                              me the full details.   Could be off-list,
                              but this is sufficiently important that we
                              will want the full results known.<br>
                              <br>
                              I have a specific case of official testing
                              of one of my stoves with unfavorable
                              results for Low-Heat Efficiency
                              (simmering).   I will add that into the
                              list of examples and provide the details
                              very soon.<br>
                              <br>
                              I invite anyone else who has something to
                              report about simmering efficiency to also
                              send details of their experiences, either
                              favorable or unfavorable or neutral.  <br>
                              <br>
                              The examination of the questionable
                              methods about simmer efficiency might take
                              some days, maybe weeks.   But not the
                              months or years that this debate has been
                              "simmering".   <br>
                              <br>
                              Remember:  A testing center that properly
                              conducts testing using an endorsed but
                              possibly flawed procedure is NOT a
                              culprit.  The culprit is the testing
                              protocols, <u>IF found to be faulty.   </u>And
                              we hope that the testing center people
                              (employees and leaders) who understand the
                              technical aspects of the calculations will
                              be among those who can help resolve these
                              serious issues.<br>
                              <br>
                              Even those who developed protocols that
                              are eventually shown to be faulty are not
                              culprits.   Mistakes can be made.   
                              However, the culprits can include those
                              who advocate a protocol that he or she
                              knows (or reasonably suspects) to be
                              faulty.<br>
