SCORE-Stove for Cooking,Refrigeration and Electricity

A team at Imperial College reports on the "Stove for Cooking, Refrigeration and Electricity"(SCORE):

The electricity generating and refrigerating aspects of SCORE will be operated through thermoacoustic principles, which convert sound waves into heat and vice versa. This technology is far more efficient and less polluting than burning wood in an open fire, currently the primary cooking method of two billion people around the world. Dr Pullen(Research team leader) adds:
"Using this technology while ensuring that the device is relatively low-cost and can be produced using local materials and labour is one of the great challenges of this project. Thermoacoustic systems have always been expensive and high-tech - a great deal of the first stage of this project will be taken up with translating the technology into something that can easily be mass produced."
