A turbine (2) including an electrical power generator (22) and a turbine blade assembly (4) including a main shaft (12) having a main, longitudinal axis, one or two hubs (10) rotatably mounted on the main shaft (12) so as to rotatable about the main axis (12), a plurality of elongate blades (14) rotatably mounted on each hub (10) and which extend outwardly from the same side of the respective hub (10) at the same angle relative to the main shaft and which are disposed rationally symmetrically on the hub (10) and a blade rotation gearing which couples each blade to the main shaft (12) so that each blade rotates 180° relative to hub for each 360° rotation of the hub (10) relative to the main shaft (12), and in which each hub (10) is coupled to the electrical power generator (22) so that rotation of each hub (10) on the main shaft (912) causes the electrical power generator (22) to generate electricity. |
