5 is a schematic cross sectional view of a fifth embodiment of a power generator; Fig. 9 is a schematic cross sectional view of a ninth embodiment of a power generator. 2 is a schematic cross sectional view of a second embodiment of a power generator; Fig. The increased fluid passing through the blade assembly 14 dramatically increases the power output of the assembly 1Oc. Fig. This advantageously allows the turbine efficiency and power output to be significantly increased for a range of flow velocities. For example, in another embodiment (not shown), the bearing 26 can be removed such that the bearing 28 is a single bearing to support both the axial and radial forces of the shaft 24. The stay cables 38 can also be removed such that the assembly 10a is supported by only the stay cables 36 and finds its’ own optimal alignment to flow much like a windsock does.

Alternative arrangements of the stay cables 36 and 38 1o may be more suitable for other applications. Known installations for harvesting hydropower, for example tidal power, on the other hand, have relatively higher generation capacity. I and 2 and like reference numerals to those used in describing the first and second embodiments shall be used to indicate like features in Fig 3. In the assembly 10c, the blade assembly 14 has a blade arrangement, in the form of a series of independent beams 22 which are arranged in a generally helical fashion 25 about the rotational axis 20. The beams 22 are connected to the shaft 24 with sufficient clearance so they can rotated about the axis 20 with respect to each other. WO 2009/062261 PCT/AU2008/001704 11 The length of each of the beams 22 decreases as they wind around the shaft 24 from the head end 16 to the tail end 18 within the generally frusto-conical boundary defined by the intermediate section 50c of the shroud 50. The shroud is similar to that described with reference to assembly 1 Oa in Fig.

The blades 44 reduce in diameter as they wind around the shaft 24 from the head end 16 to the tail end 18 following the internal dimension of the shroud 50. Remedio para dolor de espalda y cuello . The distal ends of the blades 44 are also bonded to the interior surface of the shroud 50. As a result, in use, the shroud 50 rotates with the blades 44, which creates a vortex in 5 front of the shroud 50. The shroud 50 is of multi section construction having a head end section 50a, via which the flowing fluid 12 enters the shroud 50, a tail end section 50b, via which the flowing fluid 12 exits the shroud 50, and an elongated intermediate section 50c extending between the head end section 50a and the tail end section 50b. The intermediate section 10 50c also converges in diameter from the head end section 50a towards the tail end section 50b. The head end section 50a of the shroud 50 also converges towards the intermediate section 50c and the tail end section 50b diverges away from the intermediate section 50c such that the shroud 50 is generally in the form of a converging-diverging venturi having a converging elongated throat defined by the intermediate section 50c. At all points along is its length, the shroud 50 has a circular cross-sectional profile.
The present invention relates also to an electrical power generator installation including such electrical power generator. In another form, the electrical power generator may also include a current supply electrically connected to each secondary coil, for energizing each secondary coil in order to induce a magnetic field which induces a current in each primary coil. 4 In another embodiment, if desired, the blade arrangement preferably includes one or more continuous helical blades.
