Cardboard oven works on solar powerKyoto Box wins green award
09 April 2009
A solar-powered cardboard oven, known as the Kyoto Box, has won an environmental award.
The Kyoto Box is a simple invention made from two cardboard boxes - one inside the other - covered by an acrylic sheet. There's basic insulation between the boxes. It works as a hob making it able to cook food and bring water to the boil.The device uses reflective foil and black paint to ensure maximum absorption of solar energy.

Climate change award
The Kyoto Box won the Financial Times Climate Change Challenge award, which is sponsored by Hewlett Packard and organised by the sustainable development charity, Forum for the Future. It was set up to encourage the development of inventions that might have a positive impact on the changing climate.
The Kyoto Box's inventor, Kenyan-based Jon Bohmer, won a prize of US$75,000 (£51,000).
The oven costs around £3.50 to make and will be given away for free, is aimed the 3 billion people of the world who currently use firewood to cook.
Not only would the introduction of the Kyoto Box to such communities cut carbon emissions from burning wood, but there are also sanitary benefits from boiling water to drink.
The invention was pitted against nearly 300 other entries, which were voted for by the public and judged by a panel including Sir Richard Branson.
