Abstract
An ultralight stove comprises a fuel reservoir having a plurality of jet holes in the top through which vaporized fuel escapes and burns, a portion of which is directed toward a heat conducting heat transfer plug, heat from which being conducted through the heat transfer plug to the reservoir where it heats fuel in the reservoir causing increased fuel vaporization that pressurizes the reservoir which in turn causing pressurized fuel to escape through the jet holes resulting in increased heat to the heat transfer plug, the cycle continuing until a fuel consumption and temperature equilibrium is obtained where the heat transfer plug and reservoir reach maximum operating temperatures. An external fuel absorber on the reservoir top receives fuel which when ignited initially heats the heat transfer plug to initiate stove operation.
