Abstract: A method and apparatus are provided for a stackable dispenser for coiled material. According to one embodiment, the stackable dispenser comprises a first container comprising a substantially circular base portion defining a central opening. An outer wall extends from an outer edge of the base portion, and an inner wall extends from an edge of the central opening in the same direction as the outer wall. The dispenser includes a cover comprising a substantially circular base portion defining a central opening wherein the base portion of the cover is mounted on an edge of the outer wall of the first container opposite the base portion of the first container, and wherein the central opening of the base portion of the cover is substantially aligned with the central opening of the base portion of the first container.

Abstract: A wood gasification apparatus in which cellulosic material is transported by an auger through a housing and heated to vaporize at least a portion of the cellulosic material by frictional heating. The auger and housing define a spiral void through which the cellulosic material is propelled from the inlet to the outlet, and which continually decreases in volume from the inlet to the outlet. The ever decreasing volume of the void increases the pressure on the cellulosic material and maximizes the frictional heating until the material reaches a vaporization temperature.
