An improved method and means for transforming kinetic energy into mechanical energy to generate hydroelectric power. A submersible scoop-like composite structure (10) with a hollow, tapered, inner chamber to funnel moving water through a turbine (22). The structure (10) has a hydrodynamically clean outer hull with cambered surfaces to increase the velocity of moving water to enhance the turbine's (22) efficiency. The structure (10) has a large orifice with a protective grill (14). The body of the structure (10) contains a vertical stabilizer petition (13) to keep the structure (10) parallel with the direction of the moving water. The detachable turbine (22) is housed in a tube (11) attached aft of the structure (10). The detachable generator (25A, 25B, 25C) is housed in a protective housing (12A, 12B, 12C) and attached to the turbine housing (11). The turbine (22) is coupled to the generator (25A, 25B, 25C) by a turbine drive shaft (24) through a gear box (23) to a generator drive shaft (26A, 26B, 26C). The turbine drive shaft (24) is supported by a front vertical support (27) and a rear vertical support (28). The generator drive shaft (26A, 26B, 26C) is protected by a generator drive shaft housing (29A, 29B, 29C). The entire structure is attached to an anchor base (16A, 16B, 18A, 18B, 21) by legs (15A, 15B, 17A, 19A, 19B, 20) The anchor base is fixed to a submerged medium. The scoop-like composite structure is formed from rigid material and submerged, whereby it cannot be seen from the surface. The structure is cost effective, efficient, produces no known pollution, and is not susceptible to weather related damage.
