Rammed Earth Cookstove in Chad

David DeArmey of Envodev shared these images of what will hopefully be the first of  many rammed earth cookstoves in Chad  .

Here is the typical kitchen set up in the region. There are obviously a few drawbacks to cooking over an open fire indoors, which we have outlined before.

It will take a bit of time to get this ...
...looking like this.

The team is up to the task.

Each piece was hand-sawn to fit perfectly.

 These cylinders were carved from the log we saw above.
That is some very fine work!

 The carpentry team are pleased with their results.

 Here is the clay soil ready to be rammed into the form.
Everyone helps!

 The form was removed and the stove flipped into place.

Project completed!

Smoke outside, not inside.

finally got serious about rammed earth and I have read your blog from start to finish to bad most of the older links are dead, took a good extra day to google down most of the broken links to read the reference info

a few years ago i almost bought into the sirewall thing glad I didnt.

I did purchase the 300$ book though ;-/

keep up the good work was a really great read

I can't wait to get my hands on a used copy of that very expensive book. Keep me posted on your projects...

It's great to see this design being taken up in Chad.

It may be necessary to revise the dimensions and layout of the stove depending on the type of fuel used.

For example - if local people want to use very large logs, the stove could have 2 large openings for the logs (maybe one at the front, one at the side) so that the ends of the logs can be inserted to a point where the fire takes place; then the earth stove provides shelter from the wind, a level platform for the pots, and escape to the outside for the smoke.

Other fuels, such as rice husk, will need different modifications. Please make your own design to suit your environment and let us know how you get on here :

sure i am missing something but how is the earth rammed around the combustion chamber and flue ?

why is the combustion chamber so small in comparison with the volume of the whole 'box' ? The comment above about larger pieces of fuel is good because a decent lamb stew would need several hours of simmering. i would want to pack the chamber with several hours of fuel and go do something else while it cooked. In principle it might seem this design is like a horizontal 'Samovar' ? it would be great to incorporate a water tank in the design that is heated by conduction rather than wasting heat in the thermal mass of the rammed earth ? Would a secondary chamber in the form (say 20-30 Litres) be used to create a watertight hot tank ?
