Monday, April 22, in Puno we spent much of the day buying parts for an improved wood cook stove for Eufrasia. We've had this dream for over a decade as we observed smokey kitchens and worried about lung damage of the cooks and the children.
Felipe Huatta Cruz had taken a workshop in estufas mejoradas in Lima, and we contracted him to come help install such a stove in Eufrasia's kitchen. The old kitchen had NO CHIMNEY, only an opening in the ceiling, and was horribly smokey. Even the bedrooms on the upper floor became intolerable when someone was cooking with wood early in the morning.
The essential elements that make the stove clean burning are 1) a chimney, 2) a damper and 3) a primary air source UNDER the fire.
The base for the stove is a terra cotta shell, or concha, with three burner holes and a flue hole at the back. Ruperta helped choose one in the market in Puno.

|We bought the metal plate too small, so Felipe bent a length of rebar to hold it in place.|
|Hole knocked through the stone and adobe wall for the flue opening|

We bought sheet metal, which Silvano and Sam cut the long way and rolled into chimney pipes.

Now Ruperta wants one right away. She grew up in a smokey kitchen and already has some lung issues.
