[Stoves] Practical Stoves- Introducing The Versatile Stove

[Paul Anderson]

Dear all,

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.

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.

I expect some significant progress by and during these events:
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.

B.  Stove Camp 2017 at Aprovecho (usually late July or early August).

Personal opinion:  Worthy effort; still a long way to go; many surprises 
yet to come; do not underestimate a new approach.

Best wishes to Dale and all who can contribute to this effort.

Paul
