Abstract
An irrigation device, such as a sprinkler, includes an electric generator for generating electricity. The sprinkler includes a nozzle which couples to a fluid conduit, a rotary deflector positioned downstream from the nozzle and within the atmosphere, an electric generator coupled to the rotary deflector, and a frame coupling the nozzle to the electric generator. The rotary deflector rotates about an axis as a fluid stream exiting the nozzle contacts and sprays from the rotary deflector. The rotary deflector and the rotor of the electric generator are coupled to a common axial shaft such that rotations of the rotary deflector translate to rotations of the rotor.
