Abstract: An improved water powered electric generating device which comprises a buoyant platform and a plurality of pylons fixedly mounted in the ocean or riverbed and which slidingly engages the buoyant platform, and a tower means fixedly mounted to the buoyant platform and upwardly extending therefrom. Axle means are rotatable about an axis and pivotedly adapted to the tower means and include means to rotate the axle means in an arc of substantially 120.degree., connected on one end to the tower means and on the other end to the axle means. The axle means and a plurality of radially and outwardly directed paddle arms are fixedly mounted to the first gear means and formed at the outward end thereof into a paddle to engage the moving water and rotate the first gear means. Pinion gear means toothedly engage the first gear means and are rotated thereby, and generator means are adapted to the pinion gear means and activated thereby to produce electricity.
