[Stoves] Ulaanbaatar Air Quality

[Cookswell Jikos]

Interesting discussion, sorry if this is a bit off the point but has anyone
done or heard of any new life cycle analysis research on the manufacturing
and distribution aspects of new stoves vis-a-vis the ones made in brand new
in factories as opposed to the ones made by hand at a village level with
recycled materials?

What impacts of localized pollution does this have do you think?
