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 emitted 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 Score Stove uses 30 to 50% less wood than the conventional 3 stone stove, thus, reducing deforestation.
The Score Stove may help to provide small-scale electricity generation to areas where supply is limited. As the stove traps the heat and smoke which are produced by the fire, it reduces the amount of smoke that escapes into the air and therefore minimizes negative health effects for the families. It also has a positive environmental effect, as the stove consumes much less wood than a normal 3 stone fire stove, thanks to its energy-saving design.
2.7 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 Organization (WHO, 2011).
The Score Stove will be adapted for the use of liquid paraffin as many rural communities in Africa are still highly dependent on it. Working prototypes of Score Stove exist in the UK, Malaysia, Bangladesh and Nepal.
