A firewood-saving stove model developed in the 2000s in Mexico by GIRA (Interdisciplinary Group of Rural-Appropriate Technology). Simple to construct, cost-effective and hygienic, the Patsari stove has spread widely among rural communities in Mexico.
The Patsari stove adapted and improved upon the Lorena model which was developed in Guatemala and Mexico in the 1980s. It was designed and distributed by the Grupo Interdisciplinario de Tecnología Rural Apropriada (GIRA) located in Patzcuaro, Michoacan, Mexico. During 20 years of fieldwork in collaboration with users of the Lorena design, several improvements have been incorporated into the Patsari model:
In the Purhe'pecha indigenous peoples' language, Patsari means "the one who takes care of;" the stove is designed to take care of the health of the users as well as the overall environment. The main advantages of this cooker are:
Before constructing the Patsari stove, you need a solid, stable base, not only for greater comfort for the user, but also for the sake of safety around children and pets. In general, the base measures 1m wide by 1.20m long and 60cm high; these measurements ensure sufficient space for placing kitchen utensils, for example.
The base can be constucted with available household materials or other materials that are easily affordable. Some examples of potential materials are:
These bases can be filled in completely or hollow. The hollow base has more advantages, because it can be used to store and dry wood, or for storing dishes.
If the stove is to be built in a corner of the house or near a wall, leave a gap (about 5cm) for the pieces of the formwork to be removed.
This mixture will be used to bond the bricks.

This mixture will be used for filling the interior of the cooker.
