4 and 5, details of which are provided below. Currents flow in many places in seas and oceans. Many currents flow at significant velocities and can maintain a high flowrate for extended periods of time. Many ocean currents are driven by wind and solar heating, in particular at the equator, while others result from variations in water density and salinity. First and second impellors are located within the housing and are arranged such that their swept volumes are overlapping. Arranging the generator assemblies in this manner with respect to the most frequent prevailing current ensures that the individual generator assemblies operate at their highest efficiency and are not affected by the presence of one or more other generator assemblies upstream.

1 and described above. The generator assemblies 120 are each arranged to be oriented to face in an upstream direction, as will be described in more detail hereinafter. 1, details of which are set out hereinafter. As the direction of flow of water changes, so the generator assembly must be rotated to be properly oriented with respect to the flow, that is ‘face’ in an upstream direction. Dolor muscular o de riñon . The stators 826 will correct this flow deflection and return the flow into a straight through flow before the water impacts the next blade. It is often the case that equipment used in subsea locations is operated hydraulically and relies upon a supply of pressurised hydraulic fluid to activate and power actuators and other equipment. Typically, pressurised fluid will be used locally to the system.

In addition, the system is only operable to generate energy from currents at or close to the surface of the sea or river. Accordingly, it is often the case that the retaining means is long enough to extend through the zone adjacent the bed and position the generator assembly or assemblies at a depth that has a higher incident flowrate of water. 18 and the components are indicated using the same reference numerals.
