Abstract

A gas 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. Combustible fuels 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. A gas head with a plurality of gas apertures can be inserted through a bottom plate secured to the bottommost annular ring to allow a combustible gas to be used as a combustible fuel in the combustion chamber.
