Abstract
A collapsible stove includes an expandable combustion chamber formed from nested annular rings that can collapse to about the height of a single ring and expand into a combustion chamber for burning combustible materials. Ventilation holes at the bottom of the combustion chamber provide airflow into the combustion chamber. The combustion chamber is frustoconical and narrows at the top which increases air flow into the combustion chamber via the Venturi effect. Fuel can be added and ignited in the combustion chamber and cookware containing food can be placed onto an associated top plate suspending the combustion chamber. The collapsible stove can include rotatable legs. To use the stove, the rotatable legs can be opened, allowing the nested annular rings to telescope and expand to form the combustion chamber. For carrying and storage, the nested annular rings can be collapsed and a rotatable leg can secure the rings in the collapsed configuration.
