A windmill turbine (1) with a central vertical axis having a rotor (3) and a series of blades (5) operationally connected to the rotor (3) for receiving wind and allowing a rotation of the rotor (3). The blades (5) are provided with internal heat-conducting channels (7) distributed within the blades (5) for receiving a heat-conducting liquid. The windmill also has an electrical generator operationally connected to the rotor (3) for generating electricity. The generator has a liquid cooling system connected to the internal heat conducting channels (7). The cooling system receives the heat-conducting liquid having run through the internal heat-conducting channels (7), so that in operation, the heat-conducting liquid heats the blades (5) and cools down before returning to the cooling system of the generator. The blades (5) may be provided with riblets (13) and the windmill may have an adjusting system for adjusting a position angle of the blades (5). |
