Integrated Hydroelectric Power-Generating System and Energy Storage Device
First Claim
1. Hydroelectric power-generating apparatus comprising:
- a fluid inlet;
a diffuser having (1) at least one vane supporting a diffuser hub and (2) a rotor rotatably supported by the diffuser hub and having;
(a) impeller blades;
(b) an impeller hub; and
(c) a shroud at the periphery of the rotor, the shroud including at least one magnet mounted thereto; and
a housing surrounding the shroud and having a rigidly-attached stator including laminations and at least one electrical coil,whereby a flow of fluid through the diffuser and rotor causes the rotation of the rotor and the at least one magnet induces an electric current in the at least one coil.

Abstract
A hydroelectric power-generating apparatus comprising: (1) a fluid inlet, (2) a diffuser having (a) at least one vane supporting a diffuser hub and (b) a rotor rotatably supported by the diffuser hub and having (i) impeller blades, (ii) an impeller hub, and (iii) a shroud at the periphery of the rotor, the shroud including at least one magnet, and (3) a housing surrounding the shroud and having a rigidly-attached stator including laminations and at least one electrical coil, whereby a flow of fluid through the diffuser and rotor causes the rotation of the rotor and the at least one magnet induces an electric current in the at least one coil.

- 28. Hydroelectric power-generating apparatus including a turbine and generator wherein the apparatus is mounted on a skid for submersed operation on the bottom of a waterway.
- 31. Hydroelectric power-generating apparatus including at least one submersible float, thereby enabling the apparatus to be submerged.
-
39. A hydroelectric power-generating system including a plurality of hydroelectric power-generating devices placed in series in a penstock which directs fluid from an upstream fluid level through the hydroelectric power-generating devices downstream, each device having:
-
a fluid inlet; a diffuser having (1) at least one vane supporting a diffuser hub and (2) a rotor rotatably supported by the diffuser hub and having;
(a) impeller blades;
(b) an impeller hub; and
(c) a shroud at the periphery of the rotor, the shroud carrying at least one magnet; anda housing surrounding the shroud and having a rigidly-attached stator including laminations and at least one electrical coil, whereby a flow of fluid through the diffusers and rotors causes the rotation of the rotors and the magnets, thereby inducing an electric current in the coils.
