Abstract

An underwater frame supporting a plurality of tidal turbines. The frame is tethered to a seabed fixing such that the frame and tidal turbines are positioned downstream of tidal flow. The frame is steerable so as to increase energy capture from said turbines by exposing them to undisturbed tidal flow
