<p>There is provided an aquatic turbine apparatus (10, 710, 820) including a rotor (20) coupled to one or more sets of blades (30), a bearing (170, 180, 190) for rotationally supporting the rotor (20) on a support arrangement (40), and an energy pickup arrangement (100, 110) disposed at least in part in the rotor (20) for generating energy when the rotor (20) rotates in operation relative to the support arrangement (40) in response to ocean currents and/or tidal currents acting upon the one or more sets of blades (30). The one or more sets of blades (30) are disposed in a form of a helical-blade rotor, for example a Darrieus-type rotor, operable to extract energy from tidal currents and/or ocean currents irrespective of turbulence and direction of the currents.</p> |
