Abstract

A fluid flow energy converter has at least one pair of rotors (2, 401) disposed in a common horizontal plane and locatable across a fluid flow stream (421). Each rotor is rotatable about an axis which is orthogonal to a direction of the fluid flow stream and each pair of rotors is arranged to be driven by the fluid flow stream to rotate in contra -directions. Each rotor has an axle (402) rotatable about an axis and a plurality of blades (401) extending substantially radially from the axle. Each rotor of the pair of rotors is connected by a transmission in a housing (408) to drive a common shaft (414) having a longitudinal axis located in the same plane as the axis of each of the rotors. The common shaft is arranged to provide motive force for rotating an electrical generator/alternator (412) which is located about the common shaft axis.
