(and in 2015 that percentage might be 25 or 30%), with much additional progress expected soon.

</div></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">All of what has been done has been by trial and error. This only goes so far and perhaps we are already there. I agree we are only at the 20% knowledge base but to go beyond the 20% we need to get to the chemistry level. So to move forward we now need to advance the chemistry so to know what ratios and concentrations of gases are needed that enter the secondary to produce clean combustion. Then all adjustments made to the stove are now based on controlling those measurements. Working at this level will jump us well above the 20%. </div><div class=""><br class=""></div><div class="">Thanks</div><div class=""><br class=""></div><div class="">Frank</div><div class=""><br class=""></div><div class="">Frank Shields</div><div class=""><a href="mailto:franke@cruzio.com" class="">franke@cruzio.com</a></div><div class=""><br class=""></div><div class=""> </div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Oct 11, 2015, at 7:26 AM, Paul Anderson <<a href="mailto:psanders@ilstu.edu" class="">psanders@ilstu.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

</p><p class="MsoNormal">After many months in the making, a major
document is released today about the <i class=""><u class="">Origins, History, and
Future of TLUD Micro-gasification and Cookstove Development</u></i>.
At 18 pages length (this version 1.2 is text only), it is sure to
contain some information that you do not know; at least I learned
new things while writing it. <br class="">
</p><p class="MsoNormal">The document is organized in seven time
periods. Be sure to check the periods in which you have been
active about cookstoves because you might be named in the
document. And be sure to see the final sections that deal with
future visions for 2015 to 2020, and my own shift in emphasis.<br class="">
</p><p class="MsoNormal">I truly thank everyone who has participated in
these first thirty years (1985 - 2015) of TLUD history. And I
welcome everyone to participate during the future years, which
look very promising indeed!!! For starters, we can expect that
TLUD and other micro-gasification will be in full swing at the
November GACC Forum in Ghana (to which I am headed today via South
Africa and Uganda for 3 weeks).<br class="">

Two major cookstove entities, ESMAP and the GACC, wrote in their
May 2015 technical report: <b class="">The most exciting technology trend
in the biomass cookstove sector is the growing range of forced
draft and natural draft gasifier stoves.</b> These words refer
to TLUD stoves and related micro-gasification technology that
originated in 1985. Their origin, history and future development
are covered in seven time periods, each with progress that builds
upon prior efforts:<br class="">
Pre-1985: Before modern TLUD micro-gasification Processes
observed, but not developed.<br class="">
1985 ~ 1993: Inception Reed, Wendelbo, LaFontaine and
Hottenroth.<br class="">
1994 ~ 2000: Early exposure to others Miles, Larson, English,
early Internet, conference in India.<br class="">
2001 ~ 2006: Additional exposures and incremental progress
Anderson, BP-Oorja, ETHOS.<br class="">
2007 ~ 2010: Slowly moving toward acceptance Wendelbo, Belonio,
Stove Camps, PCIA.<br class="">
2010 ~ 2015: Enlightenment BEIA Project, GACC, Roth, Winter,
Harris, char-making for biochar.<br class="">
2015 ~ 2020: Onward for dissemination and acceptance by users
Toward 30 million TLUD stoves.<br class="">
Conclusion (Authors Comment) Change of focus onto user
acceptance and carbon into soils.<br class="">
