An apparatus for converting fluidic flow into electrical energy includes a focusing chamber through with fluidic flow enters, a fin diverter positioned adjacent an entrance of the focusing chamber, a constricting chamber positioned adjacent a downstream end of the focusing chamber having a flow passage that converges in a frustum shape, a streamliner positioned adjacent an outlet end of the constricting chamber, an extraction chamber positioned adjacent the streamliner, an energy converter driven by the fluidic flow passing through the extraction chamber for producing electrical energy, and a diffusing chamber positioned to receive at an inlet end the fluidic flow passing out of the extraction chamber, the diffusing chamber having a flow passage that diverges from the inlet end of the diffusing chamber to an exhaust end at which the fluidic flow exits the apparatus.
