Cool Chips plc has created "Cool Chips" which use electrons to carry heat from one side of a vacuum diode to the other. The system, currently under development, contains no moving parts or motors and can be miniaturized for use in micro-electronic applications. In almost every electronics cooling application, an active cooling system powered by Cool Chips Technology will be superior to the more conventional passive solutions.
