Below is the abstract of a significant comparative study done in China. We thank Kirk Smith and his Stove list (different from StoveS) for the information.<br>

<p class="MsoNormal"><br>
Yes. Should we be surprised. It seems that some entities in the international leadership of clean cookstoves might be pushing for one test without sufficient attention to alternative testing methods.<br>
<br>
Note (in abstract) that: <o:p></o:p></p>

</blockquote>
<p class="MsoNormal"><br>
Sure!!! Change the duration and power, expect different test results!!! <br>
<br>
What is clear to me is that there should never be only one set of tests. People around the world have very different ways of cooking. High power in China, plancha stoves in Central America, two-arm cooking of thick foods in parts of Africa, long-simmering
bean-meals vs. quick boil of rice meals, and on and on. The people we are trying to serve want solutions that are appropriate for their circumstances.
<br>
<br>
Observation: There seems to be a slow-down in the seeking of stove testing at the major testing centers that have equipment. I can be shown to be incorrect if any testing centers would give us some statistics of numbers and types of tests that are being
requested.<br>
<br>
Of course I like the importance of emissions testing because the TLUDs and other micro-gasifiers consistently give superior results. But most funding in the past has gone to less-qualified stoves.
