Abstract

A vertical axis wind system for use in electrical power generation. The system includes a stationary base including a generator and has an elongate shaft rotatably coupled the base. The elongate shaft extends vertically from a lower end to an upper end along a vertical central axis and engages the generator. At least two arcuate blade assemblies are attached between the lower end and the upper end of the elongate shaft such that aerodynamic forces acting on the at least two arcuate blade assemblies rotate the elongate shaft for the generation of power.
