The present invention provides an open centred hydroelectric turbine having an annular stator and a rotor mounted for rotation within the stator. the turbine comprising a magnetic bearing which is adapted, by having opposing sets of rotor and stator magnets which are offset at a top and bottom of the stator, to provide both axial and radial support to the rotor.
The present invention provides a method of installing a hydroelectric turbine onto the seabed or the like while ensuring that a pre-laid electrical cable connected to the turbine prior to lowering to the seabed is not damaged during installation of the turbine, the method involving lowering the turbine towards the seabed while simultaneously displacing the turbine in order to maintain tension in the electrical cable.

SUBMERGED HYDROELECTRIC TURBINES HAVING BUOYANCY CHAMBERS
In a hydroelectric turbine having a rotor disposed within a stator housing, the rotor having an annular outer rim received by a channel in the stator housing, the improvement comprising a buoyant rotor, the rotor preferably having buoyancy chambers disposed within the rotor. The buoyancy chambers may be disposed within the annular outer rim, the blades or an annular inner rim, or combinations thereof. Preferably, the buoyancy chambers are filled with a material having a specific gravity of one or less, and most preferably the filler material is a polymer foam that adds rigidity to the rotor.
In a hydroelectric turbine having a rotor disposed within a housing, the rotor having an annular outer rim received by a channel in the housing, the improvement comprising providing at least one debris release chute in said housing such that debris captured between the rotor and the housing is released through the debris release chute.
A hydroelectric turbine for the production of electricity from tidal flow forces, the turbine having a rotor with an open center such that the blades (34) are mounted between an inner rim (32) and outer rim (33), wherein retaining members (22, 23) and anti-friction members (7, 72) are provided to limit movement of the rotor relative to the housing (21) in either axial direction, such that water flow (99) in either direction operates the turbine, but wherein the retaining members (22, 23) and the anti-friction members (71, 72) allow the rotor to shift in either axial direction in response to water flow. The anti-friction members limiting rotor travel in the axial direction are preferably of increased thickness, such that as the anti-friction members wear down, the rotor is able to shift relative to the housing in the axial direction.
