<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif; COLOR: #000000">
<DIV>Hello Lance, Zenas & Ben -- Would your group be interested in doing a study on the eco-kalan as an outdoor stove in a field setting such as in Purok San Pedro Beach and Punta Roma, Sagay City, Negros Occidental? This would be the sample of eco-kalan users I would recommend to study as the people there have, on their own accord, requested to have the eco-kalan replace the stoves they had been using. I attach Crispin's suggested tests. <BR></DIV>
<DIV>Regards,</DIV>
<DIV>Rebecca</DIV>

<P class=MsoNormal><SPAN style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d; mso-fareast-language: EN-US'>There are several methods that can be used to rate the performance of stoves used outdoors, whether portable or fixed.</SPAN></P>

<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'>One of the simplest is to conduct a cooking efficiency test based on the fuel mass consumed, its energy content, and the total mass of the meal prepared. This can be done in the field on large institutional stove or portable ones.</SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'> </SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'>Some metrics of interest to cooks are the rate at which heat flows into the pot per square centimeter (Heat Flow Rate HRF) and the cooking power as experienced by the cook (pot watts). Both are very easy to determine in the field with simple instruments: thermometer and scale plus a watch.</SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'> </SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'>The test you conduct should be designed to provide the answers to the questions you want answered. To do this I suggest (and have suggested) a set of validated testing tools that can be applied in the local circumstances. A new test protocol called the CSI-WBT is available <A href="http://tungkuindonesia.org/images/downloads/CSI_Indonesia_Test_Methods_2014-1-14_v7.pdf" target=_blank>here</A> and might suit your needs in the long term. There is also a SeTAR Thermal Efficiency Test (TET 1.55) which is used to assess the hot stove, high power heat transfer efficiency. It is a reasonable predictor of fuel consumption provided the charcoal remaining is handled correctly. It will also give you the HFR and the cooking power.</SPAN></P>

<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'>And HFR test will also give you the achievable turn down ratio for the stove.</SPAN></P>

<P class=MsoNormal><SPAN lang=EN-US style='FONT-SIZE: 11pt; FONT-FAMILY: "Calibri","sans-serif"; COLOR: #1f497d'>Please post Lance, Ben and Zenas' requests and my reply in its entirety in Stoves List for further discussion. Furthermore, I would like to hear from the group their ideas on a separate set of testing protocols and standards for outdoor cookstoves. In my opinion, current standards for indoor stoves are highly inappropriate and unfair to outdoor stoves. </SPAN></P>
