COOL CHIPS

Boeing's Phantom Works has completed an evaluation of a technology that could provide lighter, more efficient, cooling systems. Cool Chips plc, a subsidiary of California-based Borealis Exploration Ltd.{ed: Gibraltar-based Borealis Exploration Limited}, developed a form of vacuum diode that pumps heat from one side of the chip to the other to provide localized cooling and refrigeration. The solid-state technology operates silently, without use of motors or environmentally harsh fluids. Although further development is needed, Cool Chips could carve out a place in efficient thermal management of aircraft and spacecraft.
