Abstract
Abstract Electric power is produced from flow of water by means of a floating rotor, journalled on a non-rotating shaft, which is moored in place. The rotor is turned by peripheral vanes, which engage the flow. Inside the rotor are mounted energy conversion means which change the energy of rotation into electric or hydraulic power, delivered to a distribution system through the non-rotating shaft.
