They JIKO is an enduring example in various forms (clay-lined truncated, inverted cone with an air choking door). That says a lot for the efforts over the past 10 years, especially from GTZ which is a major sponsor of the R&D that has taken place since then. In particular, even a little test equipment can bring big changes in performance, beyond what can be seen with the naked eye.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Crispin<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>(Thanks Chis)<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br></span><b><span style='font-size:10.5pt;font-family:"Arial","sans-serif";color:#666666;background:yellow'><a href="http://www.gtz.de/de/dokumente/en-stove-images3-1995.pdf">http://www.gtz.de/de/dokumente/en-stove-images3-1995.pdf</a></span></b><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br><br>My MFBO (Multi Fuel Bread Oven) is also mentioned on page 39/166:<br><a href="http://biocoal.org/9.html">http://biocoal.org/9.html</a><br><br>cheers<br>Chris ADAM<br><br></span><o:p></o:p></p></div></body></html>
