    Kirk,<br>
    <br>
    Your replies to Andrew and to me were very helpful.  <br>
    <br>
    Your new diagram (I hope everyone is selecting to see the drawings)
    prompts some comments:<br>
    <br>
    1.  Under the lower plate that holds the fuel in the Rocket stove,
    there is also some air entering that will have a secondary
    function.   But the concept and intention is to minimize that
    secondary air, so showing it (maybe with a dashed blue arrow) is
    optional.<br>
    <br>
    2.  What is informative in your diagram is the use of red arrows. 
    As you wrote to Andrew, in the area of the red arrows you have
    several different gases competing for the space to get through the
    slots in the new mixer shelf.   As you wrote: 
    <blockquote type="cite"><font face="Arial" size="2">The mixer
        reduces the quantity of primary air needed from under the
        [Rocket] shelf.  Too much blows the flame out the mouth of the
        stove.  </font></blockquote>
    In Rocket language, the exposed  ends of the stick fuel (over the
    Rocket grate) are getting primary air which you could want to
    restrict, that is, to have a deficiency of primary air, resulting in
    heat for pyrolysis but not much secondary air.   This MIGHT mean
    that the air entering under the "fuel shelf" (which has a grate at
    the interior end) MIGHT be progressively cut back by using a door or
    other controller.  Such control has not been done on Rocket stoves,
    as far as I know.  This action would be enhancing the pyrolytic
    activity, and is akin to (but not the same as) limiting the air in a
    TLUD.  (Remember that Rocket stoves require the advancement of the
    stick fuel into the area over the grate of the fuel shelf.)<br>
    <br>
    3.  Continuing:  The red arrows involve the pyrolytic gases, any
    excess oxygen, N2, and the air that is entering alongside and above
    the stick fuel.  That new air is coming in from one side only (but
    that could be changed if merited).  Some of that is primary
    (reaching raw and torrified fuel).   And some is secondary
    (combusting some of the created gases).  **** Realization: 
    Therefore it is of little consequence that some air UNDER the fuel
    shelf would "survive" to become secondary burning in the red zone,
    quite similar to the incoming (blue arrow) secondary air alongside
    the entering fuel.<br>
    <br>
    NOTE:  In case it is not obvious, there is no structural
    (device-related) separation of the air as primary or secondary. 
    Some of the O2 molecules end up with a primary function (supporting
    pyrolysis of the biomass) and others with a secondary function
    (supporting combustion of the gases).   And some of the O2 could be
    consumed in char-gasification.  <br>
    <br>
    4.  Continuing:  The slot restrictions of the mixer plate result in
    a large surface area of the rising (red arrow) "stuff" to come into
    contact with the air (O2) on the top side of the mixer.  GREAT!!!<br>
    <br>
    5.  I suggest another color (orange??) for a spiral of lines through
    the stationary blades and upward a short distance, indicating the
    zone for the <u>time </u>of combustion to become more complete. 
    And that transitions into some other color (or dashed lines??) to
    show the rise of the heat and emissions gases (to be quite clean
    mainly as CO2 and H2O and N2 ) that contact the cooking pot.<br>
    <br>
    6.  I question one part of this generalized drawing, and it suggests
    an issue that could merit experimental research.  Above the green
    mixer plate, there are five each of red and blue arrows showing the
    flows through the slots.  The 4 arrows (2 red and 2 blue) on the
    right side are coming up under the stove body, not under the static
    blades in the vertical shaft (a pre-pot chimney or riser).   
    Subject to experimental results, perhaps there should only be
    slits/slots under the blades.  This also means that the diameter of
    the vertical shaft / riser could become more important relating to
    the thermal power of the stove.<br>
    <br>
    7.  It is evident that the entry of the secondary air above the
    mixer plate could be controlled, such as by an entry door. 
    Experiments could even use a small fan to force that air (checking
    on impact on emissions).<br>
    <br>
    8.  But there remains the opening through which the fuel is being
    fed into the stove.  With a few exceptions, Rocket stoves do not
    attempt to restrict (or block) the entry of the air entering
    along-side the wood.   And different amounts of fuel will impact the
    amounts of air that can enter.  The net result is less control over
    the processes.  <br>
    <br>
    9.  However, imagine that the fuel entry was with a door to close,
    and that the fuel could be advanced horizontally inward via some
    mechanism (spring action, gravity on a slope, a horizontal "plunger
    with a rod or handle" to push the fuel manually, etc.).   In that
    case, the entire unit is essentially "sealed" except for the
    controllable air under the fuel shelf and above the mixer plate.  It
    is becoming closer and closer to being a gasifier with controlled
    creation of the gases and controlled combustion of the gases a
    (short) distance and time from where the gases are created.  In that
    case it would be sufficiently different from a Rocket stove so that
    it could merit a different name for the technology.  And I suspect
    that somewhere in the 150 years (or more) of gasifier development
    there might have been such a device made, but it certainly would not
    have been for a cookstove, but instead being much larger in both
    physical size and heat output.  [BTW, industrial large units are
    generally easier to make functional than units small enough for
    households.]<br>
    <br>
    Kirk, I think you are on to something.  Please keep us informed of
    your progress, whichever directions you choose to take your
    actions.   We all hope that others will participate, also.   <br>

        Kirk,<br>
        <br>
        Nice!!!!   Very "Kirk-wellian" or "Harris-oniam".   (And those
        are compliments!!!).<br>
        <br>
        1,  You might want to try having more of the "nose" (innermost
        part of the secondary air shelf) to be blocked off to force even
        more of the flame nearer the center.  There are so many ways to
        modify what you have caught as a concept.  And I know that you
        do those modifications so well and with good observations of the
        results.  I am sure that this is of GREAT interest to Aprovecho
        and all who have worked so hard regarding Rocket stove
        technology and dissemination.<br>
        <br>
        2.  Your drawing does not show the standard shelf and grate of
        the classic Rocket stove.  Please confirm it that shelf is still
        in the design (I think that it probably should be.)  Removing
        that shelf would remove the most fundamental characteristic of
        Rocket technology.<br>
        <br>
        3.  Your drawing does not acknowledge that the air entering
        under your secondary air shelf has BOTH primary and secondary
        combustion functions (because some of the created pyrolytic
        gases are being burned with the surplus of air that is
        entering.  Very difficult to gain additional control over the
        air flows, (and why Rocket stoves are not gasifiers, which have
        gas production and gas combustion sufficiently separate to have
        control over both.)  How could you change your drawing to
        illustrate this? <br>
        <br>
        Looking forward to your next report.<br>

                    <br>
                    ****<br>
                    What soured me on what is marketed as science? Well,
                    the marketing. Of spurious theories and concocted
                    data. <br>
                    <br>
                    But that is ok. Science evolves. New paradigms
                    emerge. Science struggles through. <br>
                    <br>
                    What stinks to high heaven, however, is the abuse of
                    science by the advocates, the saviors of the poor
                    ready to market ADALYs. <br>
                    <br>
                    I don't celebrate my ignorance. I do object to
                    volunteered blindness. <br>
                    <br>
                    I have a single positive suggestion -- dump the ISO
                    exercise. Get out of the box mentality, look at the
                    cook and food, not fuel ideologies. <br>

                                                      My humble (!)
                                                      suggestion to
                                                      well-meaning stove
                                                      designers: Avoid
                                                      and ignore
                                                      advocates' deceit
                                                      and pretense of
                                                      knowledge. Don't
                                                      insult the pursuit
                                                      of knowledge -
                                                      with all the
                                                      qualifiers about
                                                      assumptions and
                                                      uncertainties that
                                                      researchers do
                                                      emphasize but the
                                                      ritual of
                                                      cite-o-logy
                                                      ignores. It is
                                                      unethical to be
                                                      guided by
                                                      unconvincing
                                                      science just
                                                      because it is done
                                                      by scientists. <br>
                                                      <br>
                                                      What is to be
                                                      done? a) Keep on
                                                      innovating for
                                                      specific
                                                      geographic
                                                      markets,
                                                      considering a
                                                      variety of fuels
                                                      and appliances,
                                                      focusing first and
                                                      foremost on "cook
                                                      food"; b)
                                                      Formulate your
                                                      ideas of market
                                                      size and timing;
                                                      c) Understand your
                                                      customers' desires
                                                      but also keep in
                                                      mind that desires
                                                      and needs are
                                                      pliable and change
                                                      in response to
                                                      factors beyond
                                                      your control; can
                                                      you make just a
                                                      fifth of the
                                                      customers in a
                                                      particular
                                                      geographic market
                                                      adapt your
                                                      stove/fuel
                                                      solution
                                                      enthusiastically?
                                                      If anybody comes
                                                      to buy a second
                                                      stove - even if
                                                      the first one is
                                                      virtually given
                                                      away - that's the
                                                      proof of your
                                                      design. d) Yes,
                                                      emissions,
                                                      exposures, fuel
                                                      consumption, time
                                                      taken to cook, are
