Developing Nations to Get Clean-Burning Stoves
Nearly three billion people in the developing world cook their meals on primitive indoor stoves fueled by crop waste, wood, coal and dung.

Sounds like the typical 'simplistic' nonsense used to promote government support of a profit making enterprise, ignoring the real issues.
SOME 'primitive stoves' have been developed over millenia to be about as efficient as possible. And suited to the local fuels.
Nor is the cost within the range of the people that actually might be able to use them..
$50 for a 'bio lite' wood cook stove may sound cheap to the rich nations but it is close to a years income for many poor nations.
And 'appropriate technology' already HAS solutions.
"Charcoal is the standard cooking fuel in East Africa. Traditionally it was burned in a metal stove or “Jiko” as stoves are called in the Swahili language. The KCJ is simply the traditional Jiko mated to a ceramic liner, producing a stove that is at least one fourth (and up to 50%) more efficient than traditional all-metal alternatives, costing only $2 to $5."
"There are three places in the cooking process where fuel can be conserved; the fuel, the stove, and the cooking pot. The greatest gains come not from the stove itself, but from how the heat the stove produces is used; paying attention to the pot rather than the stove results in the greatest fuel savings. In fact, fuel efficiency in a stove is usually much more affected by heat transfer to the pot than it is by improving combustion efficiency."
