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.
