A wind power device for sloping or pitched roofs of buildings comprises an air turbine 20 mounted at the apex of the roof 15. Air inlets 12 are located around the base of the roof, with an outlet being situated past the turbine 20. In use, the air is guided towards the air inlets 12 by baffles 17, enters at the base of the pitched roof, and due to the internal shape of the roof, accelerates as it travels towards the turbine. Non-return valves 13 are mounted at the air inlets, to ensure that the incoming air can only exit through the turbine 20. To make use of the wind energy, the turbine is connected to a heat pump 27 or an electric generator. |
