According to the World Health Program, more than three billion of the world’s population do not have access to clean cooking facilities and still rely on solid fuels such as wood, animal dung, charcoal, crop wastes, and coal for cooking and heating. These fuels are burned in extremely inefficient and highly polluting stoves and one of the world’s greatest environmental health risk factors is exposure to the emissions from these cooking stoves. This project proposes a new mechanism of self-generated air flow that boosts combustion and helps neutralize smoke. The proposed 3D printed clay stove is a doubly walled enclosure with a hollow in between, incorporating built-in apertures at the base of the exterior wall and at the top of the interior wall. The stove could be manufactured locally on-site using clay that is almost free and available anywhere. The stove capitalizes on additive manufacturing technology to leverage local material into high performing micro-infrastructure that offsets environmental and economic costs.
