A fan assembly (7) is provided for driving an electricity generator, especially for use in the production of electrical power in an electrical vehicle, wherein the fan assembly (7) functions by virtue of an air flow created by forward motion of the vehicle, the fan assembly (7) comprising two adjacent fan blade sets (14A, 14B) mounted on respective co-axially arranged hubs (13), the blades of the sets (14A, 14B) being oppositely set so that the blades (14A, 14B) and their hubs (13) rotate in contra-directions when subject to impingement by an air flow. An electricity generator (15, 15A) is also provided for use with the above fan assembly (7), the generator comprising an excitable magnetic field producing component (armature) 25 (43) and an induction electric power producing component 15 (42) which are mounted for separate rotation, especially in contra-directions by the above fan assembly (7). The generator can be located in one of the fan hubs (13).
