Abstract
An apparatus for generating electrical power includes at least one power generation assembly having a housing including a fluid chamber, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle dividing the fluid chamber into a first volume and a second volume. The apparatus also includes at least one switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with a first fluid pressure source, and a second operating state where the first volume is in fluid communication with a second fluid pressure source. The switching assembly is configured to alternate between the first operating state and the second operating state to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current in the one or more conductive coils.
