[Stoves] Climate change

That's strange - I thought we were trying to find ways to help poor people
cook with minimal risk to their health and minimal outlay on fuel gathering.
When SE Asia's emissions are growing by 700Mt CO2 every year, there ain't
much we poor stovers can do about "climate security" - and what a weasel
phrase that is!

AJ, 

I respectfully disagree. How we design and build our stoves has everything
to do with climate security.  Stoves simply do not exist in a vacuum.

Regards,

Jock

 Don't we all design and work for fuel efficiency, emission reduction and
control, and lessening of women's menial labor?   As long as we don't design
for increased fuel consumption and increased green house gas emission our
work is in harmony with mitigating climate change.   Whether women's and
children's health, or conservation, or climate change is foremost in our
minds is not too important is it?  Lucky for us, these goals are compatible
and integrated.    I think we can stop acting like there is a conflict here.

Hi All,

In my limited experience, blue flame is seen in TLUDs when the char starts
to burn. Yellow flame is the hottest but is also associated with the
production of black carbon. Reddish flame seems to be cleaner than yellow
with less CO and PM. I'm thinking that cooling the flame results in less
black carbon.

As far as color goes, a great looking combination is blue at the top of the
TLUD (burning the CO) and orange at the bottom when burning the char. Looks
neat.

Best,

Dean
