Abstract:
1. A barrage apparatus for extracting energy from a fluid flow, the apparatus comprising: a barrage having a surface adapted to increase the velocity of fluid flowing along the surface, and at least one turbine module having an inlet, an outlet and a turbine, the inlet being spaced from the surface, said increased velocity fluid able to flow into the inlet, operate the turbine and flow out of the outlet, the spacing between the surface and inlet defining a by-pass opening to direct increased velocity fluid past the turbine module and the outlet to assist in passage of fluid through the turbine module, characterized in that (a) the turbine module comprises a housing having an inner side wall and an outer side wall which are spaced apart, the turbine adapted to locate between the side walls, the inner side wall and the barrage surface defining at least part of the by-pass opening, and (b) the barrage comprises a parabolic shape when viewed in plan, said turbine module being located adjacent each curved end of the surface.
