The Dearman liquid air engine is an innovative heat engine that uses liquid air (or liquid nitrogen) as a “fuel” and emits cold air as exhaust. After each expansion cycle the heat exchange fluid is recovered from the exhaust and reheated to ambient temperature via a heat exchanger similar to a conventional radiator.
