Abstract

Converting the dynamic energy of a fluid to generate electrical power may be accomplished by a variety of systems, processes, devices, and techniques. In particular, implementations, the movements of a gaseous fluid body may be used for generating electrical power by driving a pump using the motion of a flow-driven moveable member that rotates in response to movement of the fluid body. The driving of the pump may pressurize a pumping fluid with pistons located in multiple chambers of the pump, and the pressurized pumping fluid may be conveyed to an electrical power generator mechanism that generates electrical power using the pressurized pumping fluid.
