    The Score Stove™2 is a low-smoke cook stove with high combustion efficiency. When cooking with wood fuel or other fuels such as dung or crop residuals, it produces additional electrical energy through the combustion heat. Using the electro-acoustic effect with the help of an innovative device, powerful sound waves are produced in combination with a linear electrical generator. The sound emmitted by the stove is no louder than a hum. The electricity produced by the Score Stove can be used to charge 12 V batteries or to provide main  AC voltage. The stove is designed to be used in developing countries and can bring electricity to people in rural or remote areas. The Score Stove uses 30 to 50%  less wood than the conventional 3 stone stove, thus, reducing deforestation. Working prototypes of Score Stove™2 exist in the UK, Malaysia, Bangladesh and Nepal. Trials have proven that the divice can produce enough electricity to light two LEDs whilst cooking a meal, eg. eggs and rice

      Description2.7 billion people still depend on firewood, charcoal, dung and crop residues for their daily cooking and heating. The health risks of the traditional cooking practices should not be underestimated: Rudimentary wood-fired cook stoves and open fires emit fine particles, carbon monoxide, and other pollutants at levels up to 100 times higher than the recommended limits set by the World Health Organisation (WHO, 2011).

      Chronic exposure to smoke from traditional cooking practices is one of the biggest, albeit least known, death causes. Every year nearly 2 million people die prematurely from illnesses, which are caused by indoor air pollution from inefficient solid fuel use in the households. Nearly 50% of pneumonia-related deaths amongst children under the age of five are due to particulate matter inhaled from indoor air pollution (WHO, 2011)
