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 are mounted between an inner rim and outer rim, where retaining members and anti-friction members are provided to prevent excessive movement of the rotor relative to the housing in either axial direction, such that water flow in either direction operates the turbine.
