  • Patent number: 8500364
    Abstract: A method is provided for installing a barrage across a body of water for generating electricity or current flow, the barrage being formed from a series of modules, each of which comprise a base structure carrying a number of substantially vertical pipe structures in a spaced, side-by-side arrangement, and a deck structure extending across the top of the pipe structures and supported by at least two pipe structures, the method comprising: preparing a series of foundation terraces across the bed of the body of water substantially perpendicular to the direction of flow, each foundation terrace providing a substantially flat base on which the base structure of one or more modules on the terraces side by side such that the base section of each module rests on a terrace and the deck structure of each module is located at substantially the same height as that of its neighboring modules.

    Abstract: A method of and modifies for installing a barrage across a body of water for generating electricity from tidal or current flow, the barrage being formed from a series of modules (12) each of which comprises a base structure (18) carrying a number of substantially vertical pipe structures (22) in a spaced, side-by-side arrangement, and a deck structure (32) extending across the top of the pipe structures and supported by at least two pipe structures, the method comprising: preparing a series of foundation terraces across the bed of the body of water substantially perpendicular to the direction of flow, each foundation terrace providing a substantially flat base on which the base structure of one or more modules can be positioned; and positioning a series of modules on the terraces side by side such that the base section of each module rests on a terrace and the deck structure of each module is located at substantially the same height as that of its neighbouring modules.

  • Publication number: 20100207393
    Abstract: Apparatus for generating electricity using tidal, wave or current flow in a body of water, comprising: an arrangement of first (10) and second (11) pipes, each first pipe (10) being provided with a series of holes (12a, 12b, 13a, 13b) spaced along its length, and the first pipes being arranged relative to the second pipes such that a venturi is defined between the walls of adjacent first and second pipes near the holes; a flow conduit having an inlet and an outlet; an impeller located in the flow conduit; and a generator connected to the impeller; wherein water from the body can enter the flow conduit via the inlet, and the first pipes are connected to the outlet of the flow conduit such that flow of water past the arrangement of first (10) and second (11) pipes causes the first pipes (10) to act as venturi pumps inducing flow from the inside of the first pipes through the holes (12, 13) so as to draw water through the flow conduit and drive the impeller.
