Led by the School of Electrical and Electronic Engineering at The University of Nottingham (U.K.), a research team is using thermoacoustic technology for the first time to convert biomass fuels into energy to power a combination stove, refrigerator, and generator. Part of the ~$4M SCORE (Stove for Cooking, Refrigeration, and Electricity) project, the research will address the energy needs of rural communities in Africa and Asia, where access to power is extremely limited.
The concept of the proposed device is based on proven thermoacoustic engines and refrigerators developed for applications such as combustion-fired natural gas liquefaction and radioisotope-fueled electric power generation. Thermoacoustics refers to the generation of sound waves through the non- uniform heating of gas. Using this technology is a more efficient way of using wood as a fuel than using an open fire to cook.
