Abstract: Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines.
