<p>The present invention relates to a turbine for location of fluid flow. Aspects of the present invention aim to overcome the problems associated with complex marine turbines and provide a simple, robust and economic design. The blades may be located downstream of the turbine body and means are provided to enable relative rotational movement between the support and the turbine such that the turbine aligns with the fluid flow and at least one bearing is configured to be in contact with the fluid. There may also be provided an electrical connection means that comprises a first connection element for rotation with the turbine and a second element connection arranged to be non-rotating and be connected to the cable to a remote location. There may also be provided a support arranged to be fixedly connected to the ground in fluid flow, wherein the support comprises an elongate member having a top end and a bottom end, the portion of the support adjacent the top end having a reduced cross sectional area to the bottom end. There may also be a generator for a marine turbine comprising a rotor arrangement and stator arrangement wherein the generator is flooded with fluid in which the marine turbine is immersed. Additionally or alternatively, the rotor and/or the stator is provided with a matrix, layer and/or coating to provide a fluid sealing function. There may also be provided an axial load bearing assembly including a braking means arranged to control rotation of the shaft.</p> |
