The invention disclosed herein comprises a system focusing water current into a relatively smaller diameter lumen, imparting vortical movement to the current, and directing the water vortex through an even smaller diameter lumen en route to turbine blades having long curved blades rotatable along an axis parallel with the lumen. Rotation of the turbine blades turns gearing interfacing with the circumference of the turbine assembly, to rotate a drive shaft connected to a generator.

1. A hydro-electric generator system to generate electricity from a water current, the system comprising: a housing including an upstream funnel portion and a constricting horizontal lumen, the upstream funnel portion orientable in a same direction as the water current and focusing the water current into the constricting horizontal lumen, the lumen having a longitudinal lumen axis generally aligned in the same direction as the water current;a throat including a throat-valve;at least one turbine, the turbine having a plurality of blades rotatable around the lumen axis;the throat-valve including a plurality of pivot plates and a coordination means for coordinating an opening and closing of the pivot plates;each pivot plate comprising a half-disc configuration including a straight edge and a circumferential edge, such that the circumferential edge has a curvature which closely follows a curvature of an interior wall of the lumen;each pivot plate pivoting on a pivot pin extending from the circumferential edge of the pivot plate through a wall of the funnel, each pivot pin connecting a respective pivot plate to the coordination means;wherein the funnel initiates a vortical movement of water into the throat-valve, andthe throat-valve, when in an open configuration, defined by the opening of the pivot plates, enhances the vortical movement of water to the blades for generating rotational force;the turbine further comprising a sleeve telescopically received within the housing lumen, the sleeve having an inner surface connected to and supporting the plurality of blades,each blade extending longitudinally in a same direction as the lumen axis, each blade having an outer peripheral edge anchored to the sleeve,an inner axial edge separated by a short distance from the lumen axis such that an interior passageway is formed about the lumen axis by the inner axial edges of the plurality of blades, anda vortically curved primary face between the peripheral edge and the axial edge, such that an entire upstream-to-downstream length of the primary face receives force from the vortical movement of the water current flowing through the lumen, thereby causing the blades, and the sleeve connected thereto, to rotate about the lumen axis;the sleeve further comprising a cogged ring encircling a periphery of the sleeve at one end thereof, andthe system further comprising a gearwheel having teeth meshing with the cogged ring, the gearwheel rotating a drive shaft extending through the housing and operably connected to an electric generator;wherein rotation of the blades by the water current causes the sleeve to rotate, thereby causing rotation of the electric generator via the gearwheel to thereby generate the electricity. 2. A hydro-electric generator system as described in claim 1, the funnel comprising an inner surface including a vortical ridge upstream of the throat-valve, the vortical ridge enhancing said vortical movement of water. 3. A hydro-electric generator system as described in claim 1, the plurality of pivot plates comprising three pivot plates, each plate having a notch near a mid-point of the straight edge for pivoting coordination with corresponding nearby notches of the other pivot plates of the throat-valve, the notch of each pivot-plate maintained in coordinating proximity to the notches of the other pivot-plates, the pivoting coordination of the pivot plates allowing for each pivot plate to diagonally overlap an adjacent pivot plate. 4. A hydro-electric generator system as described in claim 1, the coordination means comprising an outer collar encircling the throat, each of the pivot plate pivot pins comprising an exterior end yoked to the collar, such that rotation of the collar around the throat causes coordinated pivoting of all the pivot plates for opening or closing the throat-valve. 5. A hydro-electric generator system as described in claim 1, wherein the sleeve is telescopically received within a canister. 6. A hydro-electric generator system as described in claim 5, further comprising an annular convergence collar shunting water axially away from any space between the canister and the sleeve. 7. A hydro-electric generator system as described in claim 5, the system further comprising an axle-less means for governing sleeve rotation around the lumen axis. 8. A hydro-electric generator system as described in claim 7, the means for governing sleeve rotation comprising the canister telescopically received within the housing and further including a rail-ring encircling an interior periphery of the canister, the sleeve telescopically received within the canister and including at least three rail-riding wheels mounted around an outer circumference of the sleeve in cooperating alignment with the rail-ring. 9. A hydro-electric generator system as described in claim 8, the rail-ring comprising a plurality of essentially parallel rail-rings encircling the housing lumen in spaced relationship, the sleeve further comprising, for each of the rail-rings, at least three rail-riding wheels mounted around the outer circumference in cooperating alignment with a respective rail-ring. 10. A hydro-electric generator system as described in claim 1, the at least one turbine comprising a plurality of turbines aligned sequentially within the housing, each turbine independently driving a respective drive shaft rotating a respective electric generator. 11. A hydro-electric generator system to generate electricity from a water current, the system comprising: (a) a housing including an upstream funnel portion and a constricting horizontal housing lumen, the upstream funnel portion orientable in a same direction as the water current and focusing the water current into the housing lumen, the housing lumen having a longitudinal lumen axis generally aligned in the same direction as the water current;(b) a throat including a throat-valve having a plurality of pivot plates and a coordination means for coordinating an opening and closing of the pivot plates, each pivot plate comprising a half-disc configuration including a straight edge and a circumferential edge, such that the circumferential edge has a curvature which closely follows a curvature of an interior wall of the housing lumen, each pivot plate pivoting on a pivot pin extending from the circumferential edge of the pivot plate through a wall of the funnel, each pivot pin connecting a respective pivot plate to the coordination means; wherein the funnel initiates a vortical movement of water into the throat-valve, and the throat-valve, when in an open configuration, defined by the opening of the pivot plates, enhances the vortical movement of water to the blades for generating rotational force; and(c) a turbine comprising:(1) a canister defining a canister lumen, the canister telescopically received within the housing and including a rail-ring encircling an interior periphery of the canister;(2) a sleeve defining a sleeve lumen, the sleeve telescopically received within the canister and including a cogged ring encircling the sleeve and at least three rail-riding wheels mounted around an outer circumference thereof, the wheels in cooperating alignment with the rail-ring, the sleeve having an inner surface supporting a plurality of blades, each blade extending longitudinally in a same direction as the lumen axis, each blade having an outer peripheral edge anchored to the sleeve, an inner axial edge separated by a short distance from the lumen axis such that an interior passageway is formed about the lumen axis by the inner axial edges of the plurality of blades, each blade further including a vortically curved primary face between the peripheral edge and the axial edge, such that an entire upstream-to-downstream length of the primary face receives force from the vortical movement of the water current flowing through the sleeve lumen, thereby causing the blades to rotate about the lumen axis; and(3) a gearwheel having teeth meshing with the cogged ring, the gearwheel rotating a drive shaft extending through the housing and operably connected to an electric generator;wherein rotation of the blades by the water current causes the sleeve to rotate, thereby causing rotation of the electric generator via the gearwheel to thereby generate the electricity.
