An apparatus and method for extracting energy for a tidal stream in a body of the water are described. The apparatus comprises a body located in a tidal stream, a generator; and a line coupled to the generator such that relative movement between the line and the generator drives the generator. In one configuration, the body comprises a drag surface oriented substantially in the direction of the tidal stream and has at least one formation for promoting a drag force on the body. The drag force causes movement of the body with the tidal stream, which results in relative movement of the line and generator to drive the generator. |
