Dear all,<br>
<br>
I want to encourage some Stovers to get involved with Dale about
this innovative approach. This kind of work benefits from multiple
participants and the SHARING of what is discovered. Via the Stoves
Listserv is good, but also with direct contact with Dale.<br>
<br>
I have seen his stove at Stove Camp 2016, and I visited Dale in Ohio
a couple of weeks ago. This is serious work and merits our
attention and efforts. This is not a Rocket stove nor a TLUD
stove. Something fresh, with different driving forces from what is
typical "emissions driven" stove development. Emissions MIGHT be a
shortcoming of this stove, but as Nikhil has been saying, there are
other issues also. <br>
<br>
I expect some significant progress by and during these events:<br>
A. ETHOS meeting 27 - 29 January 2017 in Kirkland, WA (Seattle
area). AND possible Stove Open House at Aprovecho maybe before or
most likely immediately after ETHOS.<br>
<br>
B. Stove Camp 2017 at Aprovecho (usually late July or early
August). <br>
<br>
Personal opinion: Worthy effort; still a long way to go; many
surprises yet to come; do not underestimate a new approach.<br>
<br>
Best wishes to Dale and all who can contribute to this effort.<br>
<br>
Paul<br>

InStove for larger stoves. My work with downfeed burners in

also produce a very good stove with a lot of practical
