The invention is a stove system that is portable, has a double walled external structure for the passage of air used in combustion of the fuel, which air also maintains the external surface at a cool enough temperature that it can be touched, and which air flow prevents the waste of heat laterally to the ambient air from a hot outer surface. This increases cooking efficiency, because almost all heat that reaches the air flow between the two walls is drawn right into the combustion chamber in the form of preheated air by reason of the chimney effect. Thus almost no heat can escape the outside wall except by reaching the cooking pot bottom and pot sides after passing out the cover vents as exhaust. An internal heat concentrator ring improves the overall efficiency of the burner. The stove is preferably powered with coal, and uses about half as much coal as a conventional coal fired stove resulting from cooking efficiency. Provision is made for generation of electrical energy from the excess stove heat. Additionally, special thermally designed cook pots add to the stove system to decrease food cooking time while reducing the fuel required.
