Re: Juntos Stove pictures

["Paul S. Anderson" <psanders@ilstu.edu>]

Kevin and all,

The Juntos stove is just an early prototype for "proof of concept"

The "box A" is ANY container that supports the gasifier.

ANY fuel.  I use mainly pellets sold for "pellet stoves" in the USA, but I 
have burned twigs and pods from trees and briquettes.

NO SPECIFIC target of energy level yet.  I am proving that MANY energy 
levels can be attained from the same stove just by changing some of the 
variables.

The pictures show the "combustion units" or the "heat generation units" and 
no attempt has been made to define the "cooking surface" or the outer 
appearance or materials of a final complete stove.

The prototype is working on top of a picnic table, so it is far too high 
from the standpoint of cooking a meal.

I think that answers your question, at least as far as I am able to have 
any answers to give.

Please note:  by providing everyone with EARLY reports (such as "what I did 
last weekend") you must expect that details will be missing because we have 
not given ourselves very much time to think about our own results.  We are 
making modifications even while I type the messages, and we will test the 
changes before some of you even get your e-mail open.  Stay tuned for more 
results "as they happen".
