Abstract
An engine is configured to generate power by extracting energy from a low temperature or pressure differential. A plurality of movable masses (e.g., fluid contained in and movable between vessels) is coupled to and arranged about a shaft. When subject to a pressure differential, mass moves to a higher vessel thereby increasing its potential energy and producing a gravitational moment that encourages rotation of the plurality of masses in the first direction. The pressure differential can be created by an increase in pressure that can be generated by exposing a substance (e.g., a volatile material) to heat.
