A fully submersible apparatus for generating electricity from liquid flow as in an ocean or river current. A buoyant structure is fully submersible and has at least one pair of counter-rotating side-by-side motors with a plurality of angularly spaced radial vanes each having a plurality of rotatable subvanes such that current impinging upon the motor will impinge on a closed or solid vane to effect rotation of the motor and its shaft during a first phase of the rotational cycle and will impinge on open vanes for free passage therethrough on the return or second phase of rotation of the motor. Motors may also be provided with vanes in overlying and underlying relationship. An associated method is provided.
