[Stoves] COMPULSORY VIEWING!!! link from Re: The Aprovecho Newsletter - December 5th, 2014

[Dean Still]

Hi Huck,

I agree about chimneys. For protecting health a functional chimney seems to
me to be big help. Lots of factors, though, in a stove that will be sold.

All of the new stoves will be at ETHOS. They are in field testing now and
we expect big changes as the cooking function of the stove is improved.

Once the stoves are nearer completion there will be an open source
description of all the techniques/stoves including CAD drawings. So great
to have DOE support that has enabled a deeper investigation both in the lab
and field.

The price will be determined in 2015. I sure hope that it will be around
$10-$12 wholesale because I don't think that an above $20 retail price will
capture a significant market share. We're paying attention to retail price
in the field tests.

The stoves will be tested by third parties after completion. Our tests look
clean.

Best,

Dean
