Zusammenfassung:	Inventive systems (e.g., turbines) for harnessing hydroelectric energy are described. The turbines, includes: (1) a central longitudinal shaft configured to mount and to rotate on a central axis perpendicular to a direction of fluid flow; (2) a plurality of arcing blades coupled with the shaft, the blades extending radially outwardly from the shaft, and the blades including an airfoil cross-section along a substantial length of the blades; and (3) a hydrodynamic cap covering a location where the arcing blades couple with the shaft such that in an operating state of the turbine, presence of the hydrodynamic cap reduces an amount of bypass area, which is area outside a region that is swept by the arcing blades. Des systèmes selon l'invention (par exemple, des turbines) permettent d'exploiter l'énergie hydroélectrique. Les turbines comprennent: (1) un arbre longitudinal central conçu pour être monté et tourner sur un axe central perpendiculaire à une direction d'écoulement de fluide; (2) une pluralité de pales en forme d'arc est accouplée à l'arbre, les pales s'étendant radialement vers l'extérieur depuis l'arbre et comprenant une section transversale de surface portante sur une longueur ; et (3) un bouchon hydrodynamique recouvrant un endroit où les pales en forme d'arc s'accouplent à l'arbre de telle sorte que, à l'état de fonctionnement de la turbine, la présence du bouchon hydrodynamique réduise une partie de la surface de dérivation qui est une surface située à l'extérieur d'une région balayée par les pales en forme d'arc.
