Appliance Characteristics, Features, Qualities, Attributes and or
Considerations</DIV>
<DIV><BR></DIV>
<DIV dir=ltr>Dear Lanny,
<DIV><SPAN style="FONT-SIZE: 12pt">Iam happy to see this topic beeing brought
into consideration, but your list is to "long", sorry.</SPAN></DIV>
<DIV>How would you expect anyone to be able to compare two units related to 40
points?</DIV>
<DIV><BR></DIV>
<DIV>First of all we could link the units to type of<B> fuel </B>and fuel
<B>available</B>:</DIV>
<DIV><B style="FONT-SIZE: 12pt">Biomass</B></DIV>
<DIV> - Solid</DIV>
<DIV> - Dry Wood (moisture content
less than 20%), pellets (7%). briquettes (10%), charcoal etc</DIV>
<DIV> - Raw materials like straw,
twigs, nutshells, etc.</DIV>
<DIV> - Liquid</DIV>
<DIV> - Ethanol etc.</DIV>
<DIV><BR></DIV>
<DIV>Secondly:</DIV>
<DIV><B>With and without chimmny.</B></DIV>
<DIV>Thirdly:</DIV>
<DIV><B>Char- and none charmakeing units.</B></DIV>
<DIV><B><BR></B></DIV>
<DIV>To shorten your list, but haveing in mind the same settings, we like to
look at our ND Peko Pe, as an energy unit and linked to different tasks to be
done, like cooking, grilling, oven etc.</DIV>
<DIV>This diffrent tasks of operation can be adjusted to the situation and
incoporated with the unit as a focal point of action.</DIV>
<DIV>Just be Creative and see what Paal has done!</DIV>
<DIV><BR></DIV>
<DIV>We would like to focus on the <B>gasfier</B> units and divide them into
mainly <B>two</B> different categories:</DIV>
<DIV><B>Natural Draft</B> and</DIV>
<DIV><B>Forced draft</B> by a fan or <SPAN
style="FONT-SIZE: 12pt">Charmakeing</SPAN><SPAN style="FONT-SIZE: 12pt">
and </SPAN><SPAN style="FONT-SIZE: 12pt">None charmakeing</SPAN><SPAN
style="FONT-SIZE: 12pt">, which is very much how they operate.</SPAN></DIV>
<DIV><BR></DIV>
<DIV>The <B>ND</B> unit is very much dependent of dry fuel, while the
<B>FD</B> can accept a bit more moisture content.</DIV>
<DIV>The forced draft unit consume the char, while the natural draft let us
harvest the produced char - 20 to 25%.</DIV>
<DIV><BR></DIV>
<DIV>Biochar can also be produced and harvested in many ways, but with lower
carbon content, which "normaly" burns in an open fire, apart from the ones lit
from the top (Top Lit), see Tom Reed.</DIV>
<DIV><BR></DIV>
<DIV>According to your list, the most flexible unit will give the highest
score, a Multi Use Unit.</DIV>
<DIV>I dont see the point to be the most Multi Use Unit, as long as the main
focus should be the<SPAN style="FONT-SIZE: 12pt"> emmissions and the
available (short distance) fuel in the region.</SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt"><BR></SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt">We feel this is a bit of a divertion of the
main topic for stove operations, namely field testing of emmissions and
efficiency.</SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt"><BR></SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt">We dont say that caracteristics, features
etc. is of no interest, but the main issue should be to involve the
<B>cook</B> and women going to use this applicants.</SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt">They are not only missing here in this
forum, but also in most conferences related to this issue.</SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt">WHY??</SPAN></DIV>
<DIV><SPAN style="FONT-SIZE: 12pt">Invite them and Iam quite sure they will
have a lot of relevant questions and even good answers.</SPAN></DIV>

of cooking appliance and type of cooking task, like cooking <BR>> with
woks, pots, pans, griddles, ovens, and or grills.<BR>> <BR>> 2. Volume
to be cooked- Is the stove sized to cook the right quantity, <BR>> for
individual, household, commercial, institutional, or industrial size.<BR>>
<BR>> 3. Cost and payoff period, how much work will the stove do, how much
<BR>> fuel will it save, how much labor will it save.<BR>> <BR>> 4.
Overall functionality, how well does the stove do the job?<BR>> <BR>> 5.
Durability and ruggedness, longevity, will it last? will it burn <BR>> out?
or will it break, what is the lifespan.<BR>> <BR>> 6. Ease of use, How

level necessary to operate, and the attention period <BR>> necessary to
keep it going.<BR>> <BR>> 7. User appeal, pride of ownership, does the
