Abstract: An apparatus for generating electricity from fluid currents comprises a continuous loop structure and at least one blade movably mounted relative to the continuous loop structure and extending in a direction radially outward relative to the continuous loop structure, the at least one blade being configured to rotate about an axis of the continuous loop structure. The at least one blade may be configured to interact with fluid currents moving in a direction approximately parallel to the axis of the continuous loop structure to rotate the at least one blade about the axis of the continuous loop structure. At least a portion of the least one blade may intersect a plane of the continuous loop structure that is substantially perpendicular to the axis of the continuous loop structure. Rotation of the at least one blade may generate electrical energy.

Abstract: A system for generating electricity from fluid currents having one or more trolleys that move along a closed-loop track as a result of the action of fluid currents on one or more blades attached to each trolley. Spacing between trolleys is preferably maintained by a spacing ring to which the trolleys are attached. Optionally, one or more blades made be attached to the spacing ring. The trolleys are supported and guided either by wheels or magnetic levitation. Electrical energy is preferably created by the movement of magnets in an electrical ring attached to the trolleys with respect to a conductor connected to the track.
