Abstract
A vertical axis wind turbine apparatus includes a stationary support platform having a platform pipe fixed to the platform. The platform pipe has an axis. The apparatus also includes a power ring dimensioned and configured for rotational movement about the platform pipe and having an axis of rotation coincident with the axis of the platform pipe. The power ring includes a sleeve concentric with the platform pipe that has a plurality openings therein. A plurality of rollers is carried on the power ring and each of the rollers extends through one of the openings and abuts the platform pipe thereby facilitating rotation of the power ring about the platform pipe. A plurality of elongated blades is carried on the power ring about the periphery thereof.
