Abstract: A high efficiency stove has a chamber attached to a base. The chamber is liquid tight and holds liquid fuel such as alcohol within. At least one heat conductor is provided to capture heat and redirect it back into the fuel to increase the gasification process required for combustion. This heat is normally lost in conventional stoves. This greatly increases the efficiency of the stove and allows small size stoves to have a heat output superior to conventional stoves. In one embodiment, removable heat conductors are used to adjust heat output. In another embodiment an adjustment sleeve is used that effectively changes the height of the chamber to adjust output. Another embodiment utilizes an outer sleeve that rotates to open and close at least one airflow opening provided for that purpose. One embodiment includes cooking support legs that allows a user to use a pot or pan.
