Abstract

A system for generating electricity from fluid currents having one or more trolleys (2) that move along a closed-loop track (1) as a result of the action of fluid currents on one or more blades (11) attached to each trolley (2). Spacing between trolleys (2) is preferably maintained by a spacing ring (13) to which the trolleys (2) are attached. Optionally, one or more blades (11) may be attached to the spacing ring (13). The trolleys (2) are supported and guided either by wheels (4) or magnetic levitation (5). Electrical energy is preferably created by the movement of magnets (14) in an electrical ring (15) attached to the trolleys (2) with respect to a conductor (16) connected to the track (1).
