Abstract:

A spiral turbine blade having at least one concave compartment that is rotatable by a moving fluid for the generation of electricity is provided. A spiral turbine blade is aligned so that the axis of rotation is generally parallel to the mean direction of a moving fluid. Attached to the intake-facing side of the at least one spiral turbine blade are concave compartments comprised of an intake void, interior space, and exit void. The concave compartments are oriented to capture an additional range of velocity imaginary vectors; specifically those aligned via vortex inducing elements, such as spiral depressions on a conical intake shroud, thereby augmenting the torque induced the spiral turbine blade, and thus improving the conversion efficiency and electrical energy output.
