Tapered helical auger turbine to convert hydrokinetic energy into electrical energy

A helical multi-piece auger rotatable by a moving fluid for the generation of energy comprising:

• two helical blades mounted onto a central shaft, each helical blade comprising multiple pieces;
• the multiple pieces including at least one constant section, the at least one constant section having a first piece of helical blade and a first outer spiral flange extending approximately perpendicularly, in both directions, from a first outer edge of the first piece of helical blade;
• the multiple pieces further including two tapered end-sections, each tapered end-section having a second piece of helical blade and a second outer spiral flange extending approximately perpendicularly, in both directions, from a second outer edge of the second piece of helical blade, the second outer spiral flange having a tapered width that is tapered moving from a vicinity of the at least one constant section toward the central shaft such that the second outer spiral flange only partially covers a length of the second outer edge;
• and
• a first and a second nose cone mounted on a left and a right end of the central shaft, respectively, the first and second nose cones both being configured to have a winged-shape body, the first and second nose cones being orientated such that a first longitudinal axis of the first nose cone is axially offset from a second longitudinal axis of the second nose cone, wherein the helical multi-piece auger is rotatable by the moving fluid to facilitate generation of energy from the rotation of the helical multi-piece auger.

• the second outer spiral flange having a tapered width that is tapered moving from a vicinity of the at least one constant section toward the central shaft such that the second outer spiral flange only partially covers a length of the second outer edge;
• and
• the second piece of helical blade having a tapered diameter such that the second outer edge tapers inward from a vicinity of the at least one constant section moving toward the central shaft until the second outer edge engages an opposite side of the central shaft from where the tapering inward of the second outer edge commenced,
• wherein the helical multi-piece auger is rotatable by the moving fluid to facilitate generation of energy from the rotation of the helical multi-piece auger.
