A high-efficiency, hybrid fluid aeolipile 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.

Wind aeolipile

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.
