The invention also encompasses the use of the rotor as described above for the production of electricity from fluid flows. For higher velocity fluid flows the rings of the generators can be hooked at the lower linear velocity end, this is the smallest diameter end of the rotor. In general, for low-speed fluid flow rings of the generators 13 they can be hooked at the higher linear speed end, that is at the larger diameter end of the rotor. The blades 2 extend between the inner peripheral surface 3 and the outer ring 1 and therefore form the enclosed flow paths. In a preferred embodiment, the rotor includes a housing located around the outer ring. The shape and design of the rotor can be selected as discussed above in relation to a preferred method. In the preferred embodiments illustrated here, the pair of conical helices are selected to have a linear increase in the radii r with a 0-polar coordinate along the longitudinal axis, each having a different initial radius.

1 is a rotor where the radii of the pair of conical helices increase in the same proportion to form a pair of parallel conical helices. However, it is equally feasible to construct the rotor via a non-linear increase in the internal and external radii r with the 0-polar coordinate through the use of a different underlying mathematical spiral such as the Arqmmediano, Euler, Fibonacci, hyperbolic spiral. As mentioned, in the present embodiment where the underlying spiral is based on the Archimedean spiral where there is a linear increase in the radius r with the polar coordinate 0, the rotor itself forms the design similar to a truncated cone.

In the embodiments described above, for the sake of simplicity, the underlying spiral is based on an Arqmmediana spiral when there is a linear increase in the radius r with the 0-polar coordinate. The pair of conical helices 5, 6 also have a section that reduces with the 0 polar coordinate when the radius increases. The method may include manufacturing one or both rotors with at least one blade arranged to rotate about a rotational axis, the method comprises: defining an internal conical helix and an external conical helix, the conical helix each has a section that is reduced when the propeller radius increases; and forms the blades as a surface that extends between the internal and external conical helices. Seen from a third aspect, the invention provides a method for manufacturing a two-stage rotor apparatus comprising: mounting a first rotor for rotation about a rotational axis, the first rotor has at least one helical blade; and a second rotor for rotation around the same rotational axis in an opposite rotational direction, the second rotor has at least one helical blade.

The rotors can each comprise at least one blade arranged to rotate about a rotational axis, the blade is formed by a surface that extends between the internal and external conical helices, the conical helices each have a section that is reduced when Increase the radius of the propeller. Preferably the rotor has a large diameter opening that is also perpendicular to the rotational axis of the rotor. The fluid can still flow parallel to the longitudinal axis and the head in the non-preferred direction but the power extraction is not optimal because a lot of energy is lost by initially aligning the incoming fluid flow to the angled rotor blades. This makes better use of the radial component of the flow that leaves one rotor and enters the other. The previous unidirectional or bidirectional two-stage rotor arises from the non-obvious realization that when the fluid leaves the rotor of unidirectional helical blades, the fluid will have both a radial and longitudinal component and that this radial component will be well suited to enter the end of smaller helical section of another unidirectional helical blade rotor, when both rotors have blades that rotate in the same direction when the section is reduced (that is, both rotors have blades clockwise when the section is reduced or both rotors have blades in the direction against time when the section is reduced).

A preferred embodiment does not allow fluid flow through the rotor opening when the fluid flow has only one radial component and no axial component. This has the effect of reducing the changes in the velocity components and therefore the mass flow is constant, the hydrodynamic reaction forces produce less. Alternatively, the internal conical helix radius may increase faster than the external conical helix radius in order to increase hydrodynamic reaction forces and torsion forces. In this case the rotors can have blades that are formed from conical helices that rotate in the same direction when the radius increases, that is, the first and second rotors have blades that are formed in the clockwise direction when the conical helix radius increases , or alternatively both rotors have paddles counterclockwise.

As can be seen from Figure 8A, the two rotors are mounted end to end on a common axis 4 of rotation. Preferably the opposite ends are directly opposed, that is, with minimal space between the two rotors. With these arrangements the rotor and the stator form an electric generator configured in such a way that it is driven by the liquid flow and directly converts the movement of the rotor into electrical energy without the need to transfer the rotational force to an additional device. A preferred embodiment does not allow fluid flow through any rotor opening when the fluid flow has only one radial component and no axial component. In a preferred embodiment the first and second rotor have an opening at the inlet or outlet end of the rotor apparatus that is arranged for axial fluid flow. Preferably the method comprises the use of a two-stage rotor apparatus to produce energy from a tidal flow, and more preferably the use of a rotor to produce electrical energy from the tidal flow.
