A reversible pump-turbine associated with a fluidic flow directing means defined as a water passageway includes shiftable body component selective displaceable to achieve alternatively, either an energy generation or an energy accumulation mode. One or more fluidic flow directing means are provided each having a, movably engineered or a fixed engineered diffuser body. Selection of energy mode is achieved by rotating the reversible pump-turbine about a verticalized axis, or a horizontalized axis, to position a selected end of its venturi adjacent the end of said fluidic flow conveying means and the other end adjacent said diffuser open end defined in said fluidic flow directing means. If only one conduit is provided, said diffusers are movably engineered into said fluidic flow directing means.
