Rocket stoves going mainstream in Central America?

A countertop sheet-metal rocket stove?





I saw this image online in my wanderings and (finally!) hunted down the original reference at http://www.miprensacr.com/region-centroamericana-casi-20-millones-de-centroamericanos-usan-la-lena-como-fuente-de-energia-para-cocinar (or go to http://www.miprensacr.com and search "estufas"). You can translate the article from Spanish to English if you paste the web page URL into translate.google.com.



And, an Ecofogon with an oven.


Are these really rocket stoves?

Also in Bolivia these chaps are doing great work with Rocket ovens and solar ovens http://www.boliviainti-sudsoleil.org/
They will even sell you ones here in France
