Called the SCORE (Stove for Cooking, Refrigeration and Electricity), the cookstove converts heat into acoustic energy and then into electricity through a linear alternator. Currently field trials are being conducted in Nepal:The final unit is expected to weigh in somewhere between 10-20 kilograms, using one kilogram of fuel (wood, dung, or any other locally-available biomass) per hour of use.
The target price for the unit is £20 ($33) -- seemingly dirt cheap, but remember that for many of the people this device is intended for that could be nearly a month's wage.
SCORE's developers are currently looking for sponsorships to conduct further field testing, with the goal of full production beginning sometime after 2012.
