Abstract: A helical auger turbine and hydrokinetic device for use with electrical generators for producing electricity. A helical turbine blade may be mounted on a central shaft, and a flange extending perpendicularly to an edge of the turbine blade. The helical auger may be a multi-section auger having radial sections covering a radial arc of between 45 degrees and 180 degrees, and that are rotational molded with identical center sections. The auger may have tapered end sections. The radial and end sections may be interlockingly mounted onto the central shaft to enable the complete transfer of torque captured by the helical auger by a moving fluid media, such as a tidal water flow, to the central shaft. The adjacent surfaces of the radial and end sections may be flush with one another to reduce disruptions of the moving fluid flowing over the completed helical auger and rotating the assembled helical auger.

Abstract: A helical multi-piece auger that is rotatable by a moving fluid for the generation of energy is provided. The helical multi-piece auger may include several interior pieces and two tapered end-pieces mounted on a central shaft. The pieces may include an outer spiral flange perpendicular, in both directions, to a portion of helical auger. Each tapered end-piece may be tapered with respect to both the outer diameter of a helical auger portion, and the width of an outer spiral flange. Each tapered end-piece may have an outer edge that effectively merges with the central shaft of the multi-piece auger over a radial arc of between 90 and 180 degrees. The helical multi-piece auger may include wing-shaped nose cones that are axially offset with respect to each other and house hydraulic components. The helical multi-piece auger may be rotatable by the moving fluid to facilitate generation of energy.

Abstract: A helical auger turbine and hydrokinetic device for use with electrical generators for producing electricity. The auger turbine includes a generally helical turbine blade rotatably mounted on a central shaft, which may be tapered at each end, and a flange extending perpendicularly to an edge of the turbine blade. At least one turbine blade support connection is included for connecting the central shaft to a support structure. An electrical generator may be powered by the helical auger turbine, that can be used in a tidal water flow. The helical auger turbine can operate a high pressure pump connected to a hydraulic accumulator for storing pressurized hydraulic fluid from the high pressure pump. An electrical generator can be operated by hydraulic fluid delivered from the hydraulic accumulator at times of slow water flow. A plurality of helical auger turbines can be horizontally oriented under water, tethered to legs of an ocean platform such as an oil rig secured to the seabed.
