<p>An apparatus for generating electricity from water flow held behind a barrier. The apparatus comprises: -a convergent section connected to a first end of a mixing tube such that a venturi is defined between the end of the convergent section and the mixing tube; -a diffuser section connected to a second end of the mixing tube, the diffuser section configured such in use such that the pressure at the exit of the diffuser section is greater than the pressure at the venturi; -a turbine tube comprising a blade assembly having a plurality of blades. The turbine tube is supported in the convergent section such that an annulus is defined between the turbine tube and the convergent section, to form a first flow passage, and the turbine tube defining a second flow passage. The turbine tube is rotatably mounted in the convergent section and the blades are attached to the inner surface of turbine tube such that in use water flow past the blades drives the rotation of the turbine tube.</p> |
