Stovers and briquette folks,<br>
<br>
I thank my infrequent correspondent Robert Haston for an
exceptionally informative message that he allows me to share with
all of you. <br>
<br>
Biggest news (to me) is about the study of the inclusion of plastics
(including PET water bottles) into biomass fuel briquettes!! Link
is given to a scientific study done in Greece. I hope our
briquette and emissions gurus will be making comments.<br>
<br>
I ask Robert to please help find out from his Greek contacts about
the testing of these briquettes in OTHER stoves. I hope that will
include the TLUDs.<br>
<br>
See also the attached about making stove structures. Reminds me of
the low density bricks by Ken Goyer and others that come together
for a hexagon shape, but for only one size of stove. Robert's
design is expandable. Robert, please revise with your suggestion
of possible "lockable angles" (by having specific short straight
segments instead of smooth curve on the ends.) I like it!!!!<br>
<br>
Robert, thanks again for providing this info. This could be
discussed at Stove Camp starting 10 days from now.<br>

<p class="MsoNormal">You might remember me sending you an email
about mixed plastic/biomass (i.e. waste from remote military
bases) as cook stove fuel.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Since then the university of Athens
expanded on the ASU Biodesign’s meta study. They did burn
tests that proved the concept.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Once again I am deployed overseas (Djibouti
Africa). The smoke from poorly operated waste
incinerators/open burn pits (which always seem to get
installed upwind) is the worst I have ever experienced.

Charcoal Trade Funding Somalia's Al-Shebab.

href="http://allafrica.com/stories/201406261350.html">http://allafrica.com/stories/201406261350.html</a>
You probably already know about the expanding deforestation
due to the growing charcoal trade south of here.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Miniaturizing the waste to fuel process
seems reasonable once you get past misplaced fears of burning
plastic. The process is straightforward: pick the cleanest
plastics, combine them in the optimal ratio, and form them
into briquettes or pellets designed specifically for
“mini-incinerator stoves”. This sure looks cleaner than the
“certified safe” burn pits on our bases. Instead of EPA
standards, you only have to beat the emissions of an sheep
dung fire.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I guess the next step would be to work on
designing and lab testing custom designed fuels for different
stove types. Aside from the size and shape, I guess the only
other factor is whether it would be best to incorporate the
plastic in the pressing or to hot coat the briquettes/pellets
afterward. This would increase their water resistance.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Of course getting the military behind this
would require some expert bona fides. This is a pretty good
location to field something. Our hanger sits right next to the
Army Civil Affairs Company. KBR just got another 53 million
dollars to run the camp. I am sure they are interested in ways
to fix their waste stream problems and polish their tarnished
reputation. Unlike Iraq or Afghanistan, this base is
expanding.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also, I was thinking of making an
expandable cook stove – like adding rocks to make a campfire
bigger. I came up with a design for cove and bead bricks that
you can strap together like barrel staves. The design (along
with a matching pedestal brick) eliminates the need for
mortar. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I attached a simple sketch of a top-down
view. It would probably have a base molded to accept the
bricks. I figure you could add some features (bumps, tabs,
pins, etc.) to lock the bricks at 45 and 60 degree angles. I
am probably missing something, but it looks like an extremely
useful design to me. It would sure be cool to see it adopted.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Feel free to forward this to your cohorts.
<o:p></o:p></p>

your great work.<o:p></o:p></p>
