Abstract

A spiral turbine includes an axle configured to rotate and one or more spiral blades coupled to the axle by one or more support connections. Each spiral blade is formed around and outside of a conical inner space which is coaxial with the axle.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Priority is claimed to U.S. provisional patent application No. 61 / 656,851, filed Jun. 7,2012, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The field of the present invention relates to turbine blades, and more specifically to turbine blades for generation of electric energy.BACKGROUND OF THE INVENTION[0003]Turbine blades are generally designed to capture energy from flowing fluids, such as flowing water or air. Various designs of wind mills and water turbines exist today and are used in many regions around the world for producing electric power through rotation powered by the flow of fluids, most commonly air or water.[0004]Many proposals have been made for gathering electricity from tidal and other water flows, using hydrokinetic energy generation. Initial proposals for hydrokinetic energy genera (ion use turbine blades that are able to rotate under pressure from the flow of wate...
