Description

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
