Xavier Devos imagined and designed his first cooker, in Burkina Faso (West Africa) in 1993, as he was in Voluntary Service Overseas.

The Devos cooker is a solar cooker, with an open focus. It allows to cook all meals in Sahel:
It is possible to knead dough (to, sorghum…) while it is boiling fast, and also to fry potatoes, doughnuts, fritters…

The cooker is made of two main parts :

  • A concentrator, covered with mirrors, allows to focus solar rays under the pot.

  • A table made of wood or steel. In the middle, there is a hole, above which we put the pot.

The table protects the cook from burns and dazzles.

Other devices:

To track the variation of solar altitude, the concentrator turns round a spindle, thanks to a lever.

The heat in the focus point can be regulated thanks to a shutter, which we can slide more or less. (like a thermostat).

This cooker is made with materials available in all countries and in Africa, to reduce the cost and make it easier to produce.
