P10462: Thermo-Electric Cook Stove #3

Project Summary Project Information

According to the World Heath Organization more than three billion people depend on biomass fuels (wood, dung, or agricultural residues) primarily for cooking. The practice of cooking with biomass has decimated many ecosystems and requires an enormous amount of human effort to gather. In addition, there is considerable evidence that exposure to biomass smoke increases the risk of common and serious diseases in both children and adults. According to the WHO studies, indoor smoke from solid fuels causes an estimated 1.6 million deaths annually.

To minimize these harmful effects associated with cooking more efficient cook stoves have been proposed. These new stoves are significantly more biomass fuel efficient and thus reduce deforestation rates. These enhanced stoves also reduce indoor air pollution, thereby reducing deaths and illnesses due to biomass cooking.

RIT is working with an NGO partner in Haiti, H.O.P.E., and funded by an EPA Energy Research Grant to develop an enhanced stove. The goal of this project is to develop a first generation thermoelectric RIT stove with a specific focus on designing a thermoelectric and battery powered fan. Team (P10451) will develop stove measurement and characterization methods and reduce them to practice. A second team (P10461) will design the basic stove and specify the air flow required from the fan. The mission of this project team is to design a power system to power the fan using thermoelectrics. This system will first be designed for an already existing camp stove and then adapted to the Haitian cook stove designed by Team P10461.
