A generator to transform lives

An affordable cooking stove that generates electricity could transform lives in the world’s poorest communities.

Developed by the University of Nottingham with EPSRC support, the concept behind the Score-Stove™ (Stove for Cooking, Refrigeration and Electricity) is a unique application of thermo-acoustics whereby heat is produced, converted into sound energy and transformed into electricity. The stove is fuelled by burning products including wood or dung and converts the heat into enough electricity to power lights and simultaneously charge a mobile phone. Each household with access to a Score-Stove could even sell surplus electricity to neighbours.

Aiming to improve the lives of more than 60M people in developing countries, the project began as a £2M research consortium. Its goal was to significantly improve health, quality of life, economic growth and social and educational opportunities in sub-Saharan Africa, the Indian sub-continent and South America. The team began by looking at the energy needs of rural communities before developing the capability to manufacture an affordable and versatile domestic appliance.

An early version Score-Stove, primarily for use as a high-efficiency, low-smoke cooking appliance, is already being used by communities in Nepal, Kenya and Zambia.

With the further development, the project is continuing to work with poor communities to develop local businesses for manufacture, repair and innovative applications.
