Abstract
A cooler capable of achieving a sufficient temperature gradient between an inside of the cooler and an outside of the cooler such that at least a partial vacuum forms within the cooler may include an enclosure defined by at least one wall and a lid. The lid may form a relatively airtight seal with a wall of the cooler when in a closed position. A vacuum release assembly may be disposed in one of the walls or lid of the cooler, the assembly being capable of reducing a pressure differential between the enclosure and the outside of the cooler.
