This looks like excellent new data. Congratulations to SeTAR for putting this out.</div><div><br></div><div> 2. Small correction on "<font face="Calibri, sans-serif"><span style="font-size: 11pt;"><i>H2 and CO is surprisingly constant</i>". At the beginning, H2 is about 1/4 as high as CO, but </span><span style="font-size: 15px;">towards</span><span style="font-size: 11pt;"> the end is 2/3 as large (2% vs 3%). Understanding the </span><span style="font-size: 15px;">origin</span><span style="font-size: 11pt;"> of such huge numbers may be helped by understanding why H2 relative growth is worse than CO. Of course understanding why there is growth of both/either is critical.</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"> I have no ideas on either topic. But these numbers further justify not trying to consume char in a TLUD.</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"> 3. A recent article by Dean Still and others emphasized that charcoal using stoves perform better with a small starting fuel load. If anyone at SeTAR is listening, I think this is a very important topic and the list would benefit a lot from hearing more on the test.</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"> 4. The label on the graph says 0% O2. Are there tests with added O2? Results of that?</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"> 5. There are 3 or 4 vertical colored lines roughly 13 </span><span style="font-size: 15px;">minutes</span><span style="font-size: 11pt;"> apart. The label might say "Pot". What are these about?</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"> 6. You (Crispin) were talking recently about excess air computations involving CO. I guess that the 2% H2 number is equally important in an energy sense as the 3% CO. True?</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"> 7.

What is being done to improve these numbers?</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;">Ron</span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><font face="Calibri, sans-serif"><span style="font-size: 11pt;"><br></span></font></div><div><br></div><div><br></div><br><div><div>On Sep 6, 2013, at 1:31 PM, Crispin Pemberton-Pigott <<a href="mailto:crispinpigott@gmail.com">crispinpigott@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-CA" link="#0563C1" vlink="#954F72" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Dear Friends<o:p></o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">This is a plot of CO(EF) and H2(EF) for a charcoal stove.<o:p></o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span><image001.jpg></span><o:p></o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">What do you suppose is the source this hydrogen?<o:p></o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin: 0mm 0mm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Note for interest that the ratio between H2 and CO is surprisingly constant throughout the test.
