Abstract: A method and apparatus for the enhanced transport of thermal energy utilizing a heat pipe operated principally in the vaporization/condensation mode. The heat pipe is a closed circuit fluid circuit having a heat source position and a heat sink position. A transport fluid is selected to enter the heat source position as a liquid, be vaporized thereat and at least partly chemically reacted with the aid of a catalyst, then transported to the heat sink position whereupon a reverse chemical reaction thereof is induced to release heat. Condensation of the transport fluid also occurs at or near the heat sink position and the transport fluid is returned to the heat source position in liquid form.
