During the Full Moon Celebration arranged by Flatbread Society in Losæter / Slow Space Bjørvika in Oslo I built and tended three so called "three-stone fires". One for cooking soup, one for baking bread, and one for cooking potatoes.
A three-stone fire is one of the most simple arrangements for cooking food over fire. Unfortunately three-stone fires are very inefficient. As little as 10 percent of the heat a three-stone fire produces is transferred to the cooking pot.
It is estimated that three billion people worldwide still cook over open fire, such as three-stone fires, or using rudimentary cookstoves. Inefficient biomass burning stoves used for cooking are major contributors to global warming, pollution, and deforestation. Every year millions of people die prematurely and fall sick from having breathed in smoke while cooking. Inefficient cookstoves are also a source of inequality since it is mainly women who gather fuel and cook, at the expense of studying or pursuing income generating work.

Three-Stone Fire is part of a series of works that deals with human relationships to fire. Other works are Tinders, We Still Carry The Fire, and A Fire at Munkebryggen.
