Abstract

A turbine (1) for extracting energy from a flowing fluid for conversion into electricity, comprising a first rotor (3) with longitudinally extending blades (6) which is mounted for rotation about a rotor axis (A) extending transversely of the direction of fluid flow, and a second rotor (7) which is also mounted for rotation about the rotor axis. The blades (10) of the second rotor are displaced radially outwardly from the blades of the first rotor so that the blades of the first rotor rotate within the space defined by the blades of the second rotor. The second rotor rotates about the rotor axis in the opposite sense to that of the first rotor. The arrangement may be such that the sense of rotation remains the same irrespective of the direction of fluid flow. One of the rotors may rotate the stator of an electrical generator, whilst the other rotates the rotor of the generator. The turbine is preferably buoyant and is useful in tethered, submerged configurations.
