An electricity generating device 10 comprises a wind turbine rotor 14, connected to an electric generator (16, figure 2), mounted within a hollow housing 12, the housing 12 having a plurality of openings defined in walls 24, 26 thereof. The device 10 has means to be physically and electrically connected to one or more like devices. The housing 12 may comprise a substantially rectangular box with a pitched roof 28 which overhangs the walls 24, 26. The device 10 is intended to be mounted on the ridge of a pitched roof of a building (figure 7), with a ridge tile (48, figure 7) located on the pitched roof 28 of the housing 12. Each device 10 may comprise a plurality of rotors 14 which may be mounted horizontally and/or vertically. The connection means may comprise corresponding projections (30, figure 5) and recesses (32, figure 5) in end walls 20, 22 of the housing 12, and an electrically conductive base (18, figure 5). Generated electricity may be stored and supplied to a building the device is mounted on, or to an external electricity supply such as the national grid. |
