From Nepal to Senegal, from Malawi to Honduras, the smoke from wood and charcoal cooking stoves claims a million and a half victims every year and contributes to the air pollution all over the world, where half of the population cooks twice a day burning biomass in inefficient stoves. That’s what Reinhold Messner has seen himself during his expeditions all over the world. The issues of deforestation, human health and quality of life simply depend on one single item in the household, let it be a kitchen or a hut, it’s the fire burning in the stove; that’s why engineers, architects, designers and artisans gather every Summer at Aprovecho Research Center in Oregon, where they test and compare their results on improved stoves. They test fuels and pots, forms and sizes, they check cooking habits and emissions, they exchange information and scientific data, looking for the perfect fire.
