[Stoves] Which technologies will best reduce CO and black carbon, improve health and safety and lower household energy costs?

[Tom Miles]

It's a world of hard choices. I have grouped the stoves and processes that
we have discussed for the last few months into five technologies. If you
could only select one, from a global perspective, which technology group
will best reduce CO and black carbon, improve health and safety and lower
household energy costs?
 
1. Improved charcoal combustion (improved Malgach, Maputo ceramic stove,
charcoal rocket, sprocket rocket, new Lao bucket, etc.)	
	
2. Improved charcoal and brick production (low emission kilns, Bioenergy
LLC, VSBK)	
	
3. Improved biomass combustion/gasification, heat transfer, integrated
cooking. (Sidewinder, center fire, rocket, Reddy "good" stove, Retained Heat
Cooking, patsari,. Inkawasi, TLUD, etc.) 	
	
4. Low cost and mass production of stoves (Sixbricks, ring mold, ecofogon)

	
5. Processing alternate fuels(canecoal briquettes, fireballs, fire biscuits,
holey briquettes, compact biogas, dung, paper, plastic, plant oil)

how many people will vote? (The site will only allow you to vote once.)
