A bi-directional hydroturbine assembly for tidal deployment. A hydroturbine is carried by a cylindrical shroud. Rotation of the hydroturbine blades by tidal currents drives rotation of the shaft, thereby converting kinetic energy into electrical energy. Stabilizer fins extend radially outwardly from the shroud along substantially the entire length of the shroud. Each comer of each stabilizer fin carries a pivot point for connection of pivoting deflectors between adjacent pivot points of adjacent stabilizer fins at the same end of the shroud. Pivoting deflectors are positioned between pivot points about the periphery of each end of the shroud and are biased such that tidal current flow in a first direction urges pivoting deflectors at the first end of the shroud into a non-deflective position, while urging pivoting deflectors at the second end of the shroud into a deflective position, and vice versa for tidal current flow in the opposite direction.

1. A bi-directional hydroturbine assembly for tidal deployment, comprising:a. a hydroturbine shroud having first and second ends and defining a shroud void; b. a hydroturbine positioned within the shroud void; c. a plurality of stabilizer fins extending radially outwardly from the hydroturbine shroud; and d. a plurality of pivoting deflectors pivotally connected between adjacent stabilizer fins about the hydroturbine shroud, whereby the inflow of the tidal current and the ebb of the tidal current biases one of the pivoting deflectors in a non-deflective position and biases another of the pivoting deflectors in a deflective position, respectively.
