An electrical generator for generating electricity from wind power comprises a rotatable shaft 3 around which at least one module 1 is arranged. The module has first and second ends that are located in spaced apart relationship along the shaft and an outer surface which is recessed between the first and second ends. A wind turbine 7 located within the recess is configured to cause the shaft to rotate. Preferably the shaft or the axle of the wind turbine is mounted within magnetic bearings. Photovoltaic or thermal devices may be located on the outer surfaces of the modules to generate further electricity from the suns light and heat, the electricity may be stored in a battery. A braking system may be included to reduce the speed of rotation of the shaft when it exceeds a threshold speed, the brakes may generate electricity when slowing the shaft down. |
