IN-CONDUIT TURBINES AND HYDROELECTRIC POWER SYSTEMS

摘要

Inventive systems (e.g., turbines) for harnessing hydroelectric energy are described. The turbines include: (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 substantially circularly arcing blades designed to couple to the shaft, each of the substantially circularly arcing blades having defined at one end one or more blade apertures; and (3) a fastening sub-assembly including fasteners, the fastening sub-assembly used for coupling the circularly arcing blades to the shaft.
