A stove that uses acoustic technology to cook and cool, and generates its own electricity, is being designed for developing communities in Africa and Asia.
The Stove for Cooking, Refrigeration and Electricity, or SCORE, could help improve the health and quality of life for the 2 billion or so people in the world who cook over open fires, its developers say.
When used in enclosed places, smoke from open fires can cause health problems. And the stoves can be notoriously inefficient.
A person can spend two hours a day collecting wood to burn in a fire that is so wasteful that 93% of the energy generated, literally, goes up in smoke.
"We make the burning more efficient so that they use less wood and have more time to spend on other things like education," says Paul Riley, the project director at the UK's University of Nottingham.
[...] The stove has electrical sockets, where homeowners can plug in, for example, a mobile phone for charging. Or they can sell the electricity as a phone-charging service.
Wow! Does it do windows as well?
