Abstract: According to some embodiments, a drum may be submerged in water and extend horizontally along a center axis between a first point on a first side of the drum and a second point on a second side of the drum opposite the first side. Three curved vanes may be attached to the drum such that the vanes, when acted upon by a water flow perpendicular to the axis, are operable to cause rotation about the axis, wherein an edge portion of each vane, located substantially opposite the drum, defines a plane substantially parallel to a plane defined by a surface of the drum located between the edge portion and the axis. An electrical generator coupled to the drum may convert rotational energy produced by the rotation about the axis into electrical energy.

Abstract: An airship in the form of a self-powered, elongated dirigible which comprises at least three sections connected together by joints. The sections including a front section with propulsion devices and control surfaces, at least one intermediate section designed to carry a payload and a rear section with control surfaces. The joints allow limited articulation between sections under gust conditions and tend to return the sections to aligned condition in calm air. A cover may provide a streamline exterior shape for the airship; alternatively the sections may have rims which mate together when there is no articulation to provide a smooth exterior shape.
