Abstract:
1. A heat differential power system for an electronic system comprising: a heat collector coupled to one or more heat generating devices in the electronic system; a housing containing a gas and having a surface thermally connected to a point or area in the electronic system cooler than the one or more heat generating devices and having another surface thermally connected to the heat collector; a first piston disposed within the housing for alternately moving the gas toward the surfaces causing the gas to expand as it nears the surface thermally connected to the heat collector and to contract as it nears the surface thermally connected to the cooler point or area; a second piston disposed within or adjacent to the housing which responds to the alternate expansion and contraction of the gas for powering the first piston; and means connected to the pistons for receiving the mechanical motion of the second piston and providing the first piston with mechanical motion.
