Kevin,

The CO chart was published June 12 at
http://bioenergylists.org/en/charcoalcoemissions

The test data was published June 5 and revised later in a nice single page
document by Aprovecho:

For defining characteristics of (WIniarski) rocket stoves download "Design
Principles for Wood Burning Cookstoves" at:

> comparing the Jiko and the 'charcoal Rocket' for fuel, energy, CO and PM.

I am curious as to why you call this arrangement a "Charcoal Rocket." Is it 
not simply a "Jiko with a chimney?"

What are the "defining features" for a Rocket Stove?
