The solar-powered cardboard cooker, known as Kyoto Box, is a cheap cooker designed for use in rural countries. It is estimated that the Kyoto Box will prevent two tonnes of carbon dioxide emissions per family per year by reducing firewood use- thus saving trees and forests.
The Kyoto Box is constructed from easily available resources. It uses two cardboard boxes, one inside the other with aluminum foil and an acrylic cover that absorbs sun rays. It can be easily packed and distributed. The Kyoto Box costs just $5 to manufacture, and the design has already gone into production in a factory in Nairobi, with a capacity to produce 2.5 million boxes a month.
The Kyoto Box stove seeks to address health problems in rural villages as well as reducing deforestation and avoiding carbon dioxide emissions. By eliminating the need to use wood, it reduces the time spent gathering firewood, and cuts down on indoor air pollution and other fire hazards. It can also provide business opportunities. The project envisions a network of women distributing thousands of the flat-pack devices from the backs of lorries to families across Africa and the developing world.
The inventor is Jon Bohmer, a Norwegian-born Kenyan based entrepreneur. The Kyoto Box won the Financial Times Climate Change Challenge in 2009.
