Cooker cum generator Score-Stove

A team of scientists at the University of Nottingham has created a new type of stove, called Score-Stove, that is used not only for cooking but also for generating electricity. The device uses thermo-acoustic cooling technology developed by the Los Alamos National Laboratory (LANL) of the United States.

Score-Stove is not just a stove, refrigerator, but also a function of a generator that promises to help rural areas without electricity in developing countries. According to Paul Riley, director of the Score project, the stove operates on the principle of harnessing the heat from cooking to operate the sound heat-sender. The stove will heat the tip of the pipe in a characteristic shape, while the other end will be cooled.

This process will cause the air inside the pipeline to be compressed and to vibrate, creating a strong sound wave and converted into electricity. Sound in the tube is more than 170dB, but outside we almost do not hear. Riley and his colleagues created 36 watts of electricity in the lab and recently began installing and testing the Score-Stove furnaces in Nepal and Bangladesh.

Despite producing only a small amount of electricity (compared to the 150 watt target of the research team), Score-Stove can change the lives of rural people by lighting and charging small electrical appliances such as electricity. mobile phones. In addition, Score-Stove improves cooking efficiency, reduces greenhouse gas emissions and limits exposure to kitchen fumes.

If produced in large quantities, a Stove kitchen is priced at $ 250 (about $ 5.2 million), but according to Riley, the team will improve the device to reduce the device price to $ 30 in the future. .
