[Stoves] Improving three stone stoves and finding out where wildjatropha grows

[Michael N Trevor]

It may not work but I love your Keep It Simple S**** idea
and think a hammered out piece of time.

I wonder if it would help to fill in two of the spaces between three of the stones with curving walls of clay, leaving one open for the fuel.  Clay would reduce heat loss due to any horizontal air currents so help keep it hotter under the pot. The clay walls could come up to within an inch or so of the bottom of the pot, which would still be supported by sitting on the three stones, so that emissions and hot air would be deflected up the pot sides. And, very important, it is something that a woman could do herself without any expense.  

 

I am trying to find out where (in what countries) jatropha is growing wild, so women could scavenge for the seeds.  Another question is whether there is a way to make a simple grate for three stone stoves to hold up the jatropha seeds.  I suppose they would burn if they were on the ground under wood. Would there be an advantage in lifting them above the wood, up close to the pot bottom?

 

I have read that half of the people who burn wood/charcoal for cooking are using three stone stoves. Trying to help the poorest of women with simple, cheap or no-cost improvements in their three stone stoves is in line with the first Millennium Development Goal of relieving extreme poverty.  I would like to find colleagues to try this idea of adding clay walls. It is not something I can do at my home. Any suggestions of where I can find people to try it?  If it appears feasible to add the mud walls, then the challenge will be to make the idea known to those who need it.
