Abstract

A turbine generator with a rotor having magnets secured in a receptacle shaped portion and spinning about a stationary core to produce electricity. Jets of fluid impinge tangentially upon a circumferential roughened surface of the rotor and are spaced such that a fanning out of each of the impinging fluid streams is minimized by its adjacent upstream fluid stream to transfer a greater force to the rotor.
