Potential Energy http://www.potentialenergy.org/ stoves are the stoves original designed in the Berkley labs for Sudan (the Darfur region). They are an energy efficient stove designed with the cook's needs in mind.
They have recently added an orange 'cool mesh' to the outside of their metal stove to help protect the stove user (and their children) from burns. The second photo is of a stove field test, where ladies in Africa can see for themselves the advantages and disadvantages of several designs.
The Berkley stove is created out of metal and then shipped to local artisans who assemble the stove in the field. This video shows part of the process.
