Abstract (en)
[origin: WO2013185068A1] 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. For configurations in which two or more spiral blades are included, the blades may be symmetrically disposed around the axle.
