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.

Abstract: A barge apparatus which includes first and second elongated pontoon members each including a buoyant foamed plastic material and decking bridging the pontoon members with the pontoon members disposed in spaced relationship. Each of the pontoon members including first and second elongated longitudinally extending members that extend substantially the entire length of the pontoon member proximate to the upper surface thereof and each of the pontoon members including first and second lower corner angles disposed in nested relatioship to the lower extremities of the buoyant foam plastic material. The apparatus also includes either a plurality of straps disposed at axially spaced intervals along each of the elongated longitudinally extending members with each of the straps extending around the buoyant foam plastic material and the first and second lower corner angles or other apparatus that joins these members.
