Solar cookers or olla bruja (magical cooker in español) capture energy from the sun to cook food or heat water. The most common variety is a box cooker which can generate temperatures up to 425F.

Why are solar cookers important in places like the Andes Mountains in Bolivia?

In remote mountain villages there is very little wood to burn and usually no electricity or fossil fuels. This makes it important to find alternative energy sources like the sun.

Bruce Stahlberg teaches residents of remote villages in Bolivia how to build and cook with solar ovens.
