Cooking With Sound
A low-cost generator with the potential to transform lives in the world’s poorest communities is now being tested across the UK and in Nepal. The Score project, led by The University of Nottingham, is developing a bio-mass burning cooking stove which also converts heat into acoustic energy and then into electricity, all in one unit.
The £2 million Score project (Stove for Cooking, Refrigeration and Electricity) brings together experts from across the world to develop the biomass-powered generator. By developing an affordable, versatile domestic appliance Score aims to address the energy needs of rural communities in Africa and Asia, where access to power is extremely limited.
Researchers in the Department of Electrical and Electronic Engineering at The University of Nottingham are working on the generator’s Linear Alternator — the part which turns the sound energy into electricity. The system uses special configurations of magnets which generate electrical energy from sound. Computer simulations of the linear alternator have proved successful, and test models are currently being constructed in the department’s workshops. (more…)
