I am member of a student chapter of Engineers Without Borders. We have built two Inkawasi stoves with somewhat disappointing results. (We are still not achieving complete combustion, the sunken pot chambers are problematic for accommodating a variety of cooking utensils, and the smoke escapes from the gap around the pot skirts.) The engineers on the team are discouraged and have given up on the rocket elbow stove design. Though I'm not an engineer, I am skeptical that the stoves were built according to specifications (one was tiny, the other huge); outside engineers who have experience with similar stoves have suggested that our combustion chamber (which was short‹only a little more than 12") was too short.

Thought you might be interested in the HELPS stove, retained heat cooker and water filter being sold through a major hardware chain in Guatemala.
