ABSTRACT A device foe extracting power from a moving fluid comprises a housing having a prime mover rotatably mounted therein. The device is provided with an inlet port positioned for receiving a second fluid stream AS2 for driving the prime mover , a large volume chamber to receive the discharge from the prime mover, and an outlet port positioned in a first fluid stream AS1. The first and second fluid streams AS1 and AS2 are spaced apart from another. The device is configured so that the direction of flow of one of the first or second fluid streams AS1 or AS2 is changed in order that the second fluid stream AS2 leaving the housing is combined with the first fluid stream AS1 at the outlet ports . The passage of the first fluid stream around the exterior of the housing gives rise to an enhanced pressure difference between the inlet and the outlet ports thereby enhancing power extraction from the moving fluid. The prime mover is provided with a plurality of vanes profiled to offer resistance to the second fluid stream AS2 passing between the inlet and outlet ports. The fluid stream may be air so that the device can be arranged for extracting power from the wind.
