A $6 cardboard box that uses solar power to cook food, clean water and could help 3 billion poor people cut greenhouse gases, has won a $75,000 prize for ideas to fight global warming

The Box, named after the United Nations’ Kyoto Protocol that seeks to cut greenhouse gases, is aimed at billions of people who use firewood to cook. It can also make it easier to boil polluted water. The Kenyan-based inventor hopes it can make solar cooking widespread in the developing world, replacing the use of wood which is driving deforestation. Organized by Forum for the Future, the competition aims to support concepts that have “moved off the drawing board and demonstrated their feasibility” for reducing greenhouse gases.  

“The Kyoto Box has the potential to transform millions of lives,” said Peter Madden, the forum’s chief executive. The box is made from two cardboard boxes, which use reflective foil（箔）and black paint to maximize absorption of solar energy. Covering the cooking pot with a transparent（透明的）cover keeps heat and water, and temperatures inside the pot can reach at least 80C.  

The idea of cooking using the Sun’s rays has been around for centuries, and a number of organizations including Solar Cookers International are already supporting their manufacture and distribution in the developing world. The Kyoto Box also improves the health of villagers who do not have to spend hours taking in wood smoke, a major cause of respiratory disease（呼吸道疾病）.  

Many countries are looking for cheap green ways to stimulate economies mired in economic crisis. More than 190 nations have agreed to work out a new U.N. climate pact to succeed Kyoto at a meeting in Copenhagen in December 2009.
