Abstract: A field-ready oven has reinforced telescoped side walls that extend and hold a base, shelf, tray support and cover spaced apart. A low air intake and a semipermeable membrane deliver air and vapor fuel to catalyst pads on the shelf. Radiant heat from exothermic reaction is diffused over a bottom of a tray. Hot gas circulates around the diffuser and tray with a chimney effect before exhausting. A lid on the cover lifts for access to the tray. A fuel container in the oven forces fuel through a capillary restriction to limit fuel flow. A spring in the container is released to start fuel flow.

Abstract: Disclosed herein is a combination outdoor cooking and firewood support apparatus having a frusto-conical frame designed to support firewood in a substantially upright orientation along a periphery of the frame in a manner such that the firewood lean toward the center of the frame. A cooking grate can be positioned on the upper end of the frame over the interior area so that food can be cooked over heat generated by the leftover coal from the burnt firewood that fell into the interior area of the frame. The apparatus can be collapsed into a flattened configuration when some of the arms are detached from at least one of the frame members while other arms remain attached to the frame members.
