Abstract
An engine is provided including a heat exchanger capable of providing a first temperature and a second temperature, wherein the first temperature and the second temperature are different so as to define a temperature differential. A component of the engine includes a chamber with liquid/vapor therein. In use, the heat exchanger is capable of subjecting the chamber to the first temperature source and the second temperature source in a reciprocating manner for affording a change in pressure which may be harnessed as work output.
