Hi Sharon,
Here are a few questions to help clarify your request:
1. By "green wood" do you mean wet wood of known moisture content, or do
you mean freshly-cut wood of unknown moisture content?
2. I assume I know what you mean by charcoal fuel, but what do you mean
by charcoal debris?
3. What precision do you need for these quantities? (wood->char and
energy content of different woods)

Forwarded From the Breathe Easy Network by Tom Miles:
Dear Breathe Easy Network Subscribers,
It has been a long time since we have communicated with you. We are
writing to inform you that the Breathe Easy Network, launched in 2003
has now officially become part of the HEDON Household Energy Network
(www.hedon.info) under the new name of "CleanAirSIG" - this is a HEDON
Special Interest Group (SIG) on Clean Indoor Air in the context of
poverty.
The Breathe Easy Network has run successfully for three years with
support from the Shell Foundation. In these 3 years the network
developed a 220 plus network of members. A lot of knowledge was shared
and we believe that we all benefited from the news provided through
the email newsletters and website.
The Shell Foundation has generously agreed to support the new
CleanAirSIG with some core funds which will enable us to actively
expand the networking activities of the SIG.
The CleanAirSIG will however differ in one important way from the
Breathe Easy Network - the email list will become a discussion list.
Subscribers are encouraged to subscribe to the HEDON Newsletter for
ongoing monthly news. CleanAirSIG will be a dynamic and subject
specific group where all members interested in Air Quality and Clean
Indoor Air are invited to join in.
The good news is that all the Breathe Easy Network subscribers are
automatically subscribers of the CleanAirSIG! However, if you would
not like to participate please let us know - either by sending Grant
and email (grant at ecoharmony.com), or through the HEDON User Centre
(instructions below)
The CleanAirSIG website is here: www.hedon.info/goto.php/CleanAirSIG
We look forward to your active participation in the CleanAirSIG.
With Best Wishes,
Grant Ballard-Tremeer and Karabi Dutta

Freshly cut wood of known or unknown moisture content

After cooking with the charcoal wood, there is a mix of ash and sometimes
chunkier incompletely burned bits (depending on the efficiency of the stove)

To begin with I was hoping for at least a rough rule of thumb such as
10 kilograms of freshly cut oak limbs -> Xk of wood dried for one year ->Yk
turned into charcoal fuel ->Zcharcoal debris/ashes
Sort of like the rule of thumb that people need a minimum of 2k of firewood
per day for cooking .
And would welcome scientific precision from carefully measured experiments
as well.
