Cool Chips™ is the future of all cooling, refrigeration, and thermal
management. Cool Chips
use a revolutionary new thermotunnel technology to deliver up to a
projected 70-80% of the
maximum (Carnot) theoretical efficiency for heat pumps. Conventional
refrigerators operate
at up to 50% efficiency and current thermoelectric systems (Peltier Effect)
operate at 5-8%
efficiency.
