14 May 2002 COOL CHIPS DISCLOSES APPLICATION OF QUANTUM MECHANICS IN HIGH-EFFICIENCY NANOTECH COOLING DEVICES Cool Chips plc (COLCF) said that its Cool Chips(tm), wafer-thin discs designed to produce cooling or refrigeration more efficiently than any competing technology, use quantum mechanical electron tunneling as the primary cooling mechanism. The Cool Chip is one of the first transformative technologies to emerge from the nanotechnology revolution.

The Cool Chip technology could eventually replace nearly every existing form of cooling, air conditioning, and thermal management. Prototype devices are being shown publicly for the first time at the Nanotech Planet Conference in San Jose, California, that begins today. The company has not previously disclosed the full scientific basis for its technology.

Because of the inherent advantages in cooling across a gap using electron tunneling, Cool Chips are projected to attain efficiencies much higher than those previously available in cooling systems, and they are much less than 10% of the size and weight of compressors. Cool Chips are modular, and can be packaged in arrays to cool virtually any size heat load.
