Old cardboard box wins major "green" prize. Answered
Want to get credit for an idea that is older than you are?
Simple - give it a cool name and tie the idea in with trendy green terminology.
A cheap solar cooker has won first prize in a contest for green ideas.
The Kyoto Box is made from cardboard and can be used for sterilising water or boiling or baking food.
It's just a basic solar cooker - cardboard, black paint and aluminium foil - but discussing it in terms of sustainability and carbon credits makes it worth 75,000GBP and potential mass-marketing contracts.
