you will see in the ETHOS 2017 archives when they get the presentations up. </span></p>

<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri",sans-serif">We had a very comprehensive ETHOS meeting this years. Just about everything we have discussed here in the last several weeks was discussed at the conference. There was a lot
of discussion abut stoves contexts, user needs and user choice, lab and field testing methods including the appropriate uses, pros and cons of the WBT, modifications of the WBT, the CSI methods, concerns about tier categories, etc. Much broader discussion
than in some years past. Presentations were made by a wide variety of contributors including, but not limited to, partners of the global alliance. Lots of European, African and Asian participants. Many of the attendees and presenters are on this list.

<p class="MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri",sans-serif">Very good and complete presentations by participants in the global alliance including Radha, Rainey and others. It was good to see extensive documentation which grew out of
the fuels working group that we convened in preparation for the global alliance. All of the working groups of the ISO task reported and responded. It is clear that all of the Is tasks are still a work in progress and several will be issuing drafts for comment
in the next few months. There were open invitations from all groups for people to participate in the process, even though there seem to be large numbers of participants in each group. The communications task group has promised to make information more broadly
available. Once all these presentation are online it would be useful to discuss them here in a constructive fashion.

<div>
<p class="MsoNormal">I agree with the stove designer/selector criteria for guiding the process making a stove. But before taking it into the field I suggest it be tested using the biomass available and biomass optimized for that stove. That to be included in
the instructions. I realize people are going to use the stove as they wish. But knowing how to prepare the fuel for optimum performance is a start. </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">Preparing the fuel for stoves takes time and energy and may seem silly and likely not going to be done. BUT if the fuel is the variable that now needs control we will never get cleaner stoves until this is done - no matter what stove they
use. I think a process that sizes and dries, splits, chips - whatever the available fuel before use is the best next step to cleaner stoves. </p>
