(CNN) -- It's a new idea which could resonate with communities across the developing world -- a biomass stove which also generates electricity using sound waves. The Score-Stove is a cooker, fridge and energy generator in one which harnesses waste heat from cooking to power a specially designed thermo-acoustic engine, helping provide energy to areas where access to electricity is limited. The project is being led by the UK's University of Nottingham, but has drawn on the expertise of partners around the world including the Los Alamos National Laboratory (LANL) in New Mexico. LANL researchers Scott Backhaus and Greg Swift demonstrated the first-ever thermo-acoustic engine in 1999, adapting the principles originally outlined by Scottish engineer Robert Stirling in the 19th century.
