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?
