PBS put together a nice video about the efforts to improve cooking stoves around the world:
There's more information on their web page: http://www.pbs.org/newshour/bb/building-cleaner-cookstoves/
Nancy Hughes and Gustavo Pena were highlighted with StoveTeam International. http://www.stoveteam.org/
Radha with the Global Alliance for Clean Cookstoves did a nice job outlining development challenges.
And there were a fair number of stoves that were included in the broadcast but not mentioned by name. I saw Envirofit, Burn Design Lab, Prakti and a few others represented. Let me know which ones I missed. :-) at email@example.com Online Store 100% Genuine Campus Shoes Red Ebay DET454
