A runner for a hydraulic turbine configured to reduce fish mortality. The runner includes a hub and a plurality of blades extending from the hub. Each blade includes a root connected to the hub and a tip opposite the root. Each blade further includes a leading edge opposite a trailing edge, and a ratio of a thickness of the leading edge to a diameter of the runner can range from about 0.06 to about 0.35. Further, each blade has a leading edge that is curved relative to a radial axis of the runner.

An apparatus for generating electricity from water flow held behind a barrier includes 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 that the pressure at the exit of the diffuser section is greater than the pressure at the venturi; and a turbine tube comprising a blade assembly having a plurality of blades. The turbine tube is supported in the convergent section and is rotatably mounted, the blades being attached to the inner surface of turbine tube such that water flow past the blades drives the rotation of the turbine tube.

A hydrodynamic electrification system that generates electricity from water moving from a high side to a low side and around a structure that divides the low side from the high side generally includes a water transport system that directs the water from the high side presenting a hydraulic head, over the structure, and to the low side. The system includes a power extraction system having a wheel that receives the water from said water transport system and a mounting system having a high side anchor that connects near an intake to the water transport system at the high side and having a low side anchor that connects to the power extraction system at the low side.

A portable hydropower module is provided for the generation of economical hydroelectric power at low-head sites, such as dams and weirs. More particularly, the portable hydropower modules are able to streamline the construction of power generation facilities and improve the economics of hydropower development for low-head sites. The portable hydropower modules may be produced off-site and then transported, such as by floating, to the designated low-head site. The portable hydropower modules may be specifically designed to efficiently facilitate the energy capabilities at the chosen low-head sites.
