Key social findings Smoke repels insects, if it is removed, they return There is a belief that termites will eat their house Local knowledge is essential when designing Some people like to make illicit alcohol, if the still does not fit, the stove will be rejected. If there is no-one to fix a broken stove, it stays broken Respect the village hierarchy Asking the question the right way from the right person is essential to getting the right answer. Do you want to cook in squatting position or stood up? An electrical generating stove gives incentive to change to the whole family.

Score Objectives Contribute to increasing wealth and education and improving health in developing countries by investigating appropriate and affordable novel technology to meet the energy needs of isolated rural communities in developing countries. This technology is designated, SCORE, the Stove for Cooking, Refrigeration and Electricity supply. Develop a Project Network, comprising academics from both the research team and local universities acting as knowledge hubs in the target countries, charities and non-government organisations, government representative and the local communities themselves. Exchange and focus the scientific, technological and social knowledge required by SCORE. Promote SCORE worldwide and provide a database of end-user requirements and product applications Plan and create the mechanisms for implementation of SCORE by identifying barriers to implementation and proposing solutions, forming collaborations within the developing countries, developing training strategy and suitable training materials, encouraging the acquisition of matching funding, promoting the building of local manufacturing capacity, and highlighting the wider business opportunities of SCORE in developing countries. Capture and evaluate the underpinning scientific knowledge of thermoacoustic technologies and devise a new engineering concept combining the thermoacoustic engine, electrical generation and refrigeration. Integrate these in a technology demonstrator. Study heat transfer processes in combustion and thermoacoustic systems and devise a high-efficiency, integrated combustor/heat exchanger/stove unit, capable of fulfilling its cooking function and providing the energy to the thermoacoustic element. Evaluate its performance by experimentation and integrate it into a technology demonstrator. Devise through interdisciplinary research an inexpensive method to convert acoustic energy into electricity that could be easily mass produced and evaluate its performance. Study the manufacturability, cost and the potential of using indigenous materials and local skills and based on the technology demonstrator, to design feasible SCORE prototypes, which could be field tested at selected locations. Build and demonstrate the prototypes in selected rural communities. Benchmark the design against other technologies and recommend future development paths, research and applications.
