The HomeStove is a fan-assisted, biomass stove that reduces toxic emissions by 90% and fuel consumption by 50% compared to traditional open fire cooking. The HomeStove co-generates 2W of electricity from the flame using thermoelectric generation, enabling users to charge mobile phones and lights via a USB port. The HomeStove is also compatible with locally available fuels (e.g. wood, cow dung, or crop waste), and consistent with local cooking practices (side-fed operation). The HomeStove is the only cookstove globally that can charge a mobile phone from the heat of the flame, making it uniquely suited to being sold to households without electricity access. It is an all-in-one energy hub for the home, providing ultra-clean cooking, electricity generation, and lighting. The user feeds local fuels – e.g. wood, cow dung, or crop residue – through the side of the stove. Then, they light the fuel much as they did their open fire. The heat from the flame is converted into electricity through a thermoelectric generator. This electricity powers an internal fan, which force-feeds oxygen into the flame, eliminating the smoke, and leading to the near complete combustion of the fuel. The stove generates surplus electricity – enough to charge a mobile phone and provide an evening’s worth of light.
