Cardboard cooker could help reduce carbon emissions
A solar-powered cardboard cooker could help to reduce worldwide carbon emissions while also transforming the lives of millions of villagers in developing countries.
The Kyoto Box was awarded the top prize in the Forum for the Future's FT Climate Change Challenge, a global design competition which identifies new heating and cooling solutions.
Made from two cardboard boxes and an acrylic lid, it captures and harnesses the power of the sun and can boil ten litres of water in two hours.
The creation, which costs just a few pounds to build, makes use of black paint and silver foil to help concentrate and store heat, while a layer of straw or newspaper can provide added insulation.
John Bohmer, the Kenya-based entrepreneur behind the innovation, suggested that it could cut the amount of firewood used in rural areas of developing nations by half; saving approximately two tonnes of carbon per family every year.
It is also hoped that the Kyoto Box will help to lower the number of people dying as a result of drinking dirty water.
"We're saving lives and saving trees," Mr Bohmer claimed. "I doubt if there is any other technology that can make so much impact for so little money."
He now intends to trial his invention in ten countries, including India, Indonesia, South Africa, Kenya, Uganda, Tanzania, Mozambique and Liberia.
