Today CEDESOL signed a contract with the GTZi for the first 1,000 improved stoves in their project titled “Stoves for a Better Life: Implementation of a Strategy using Ecological and Improved Stoves for Residences.”

CO/CO2 Ratio in the Charcoal Stoves Tested at Aprovecho (pdf)
Dean Still, Aprovechoi Research Center, June 23, 2006

The following graph plots the levels of COi and CO2 during one test each of the charcoal burning rocket stove and Jiko-type charcoal stove from Ghana. A higher level of CO2 suggests a higher burn rate of fuel.

It can be seen that even though the COi level for the rocket drops below 10 ppm, the CO2 level remains high suggesting a high firepower continues. The Ghana charcoal stove has a lower level of CO2 with a considerably higher level of COi.

Pema Pot Skirt

There seems to be actual agreement that pot skirts make combustion stoves better.
It is clear however that the bulk of deployed stoves do not have pot skirts.
Therefore an inexpensive pot skirt that could be made in the third and fourth world for those deployed stoves would have some usefulness.
