Arrangement For Converting Kinetic Energy Of Ocean Currents Into Electric Energy
First Claim
1. An arrangement for converting kinetic energy of ocean currents into electric energy, comprisinga floating body carrying a plurality of turbines, each turbine having an elongated cylindrical configuration and comprising at least three longitudinally adjacent, consecutive turbine rotor sections, each of which sections having at least two blades with a substantially semi-circular cross-section, the blades in adjacent rotor sections being preferably mutually circumferentially spaced 360°
- /n, where n is the number of the longitudinally adjacent turbine rotor sections,each turbine further including a rotor shaft at one end thereof for transferring a rotary motion of the turbine to an electric power generating unit on the floating body through a mechanical transmission, andwherein the floating body comprises at least two parallel, elongated, mutually spaced, interconnected pontoons and defining between the pontoons a narrowed through-passage for water currents, and that at least one pair of turbines being suspended vertically across the through-passage so as to extend downwardly from an upper deck into the through-passage and configured to rotate in opposite directions.

Abstract
Arrangements for converting kinetic energy of ocean currents into electric energy, comprising a floating body carrying a plurality of so called Savonius turbines (26), each of which having at least two blades (34) with a substantially semi-circular cross-section for transferring a rotary motion of the turbine to an electric power generating unit (40). The floating body comprises elongated, mutually spaced and interconnected pontoons (12) and defining between the pontoons a narrowed through-passage (18) for water currents. At least one pair of Savonius turbines being suspended vertically across the through-passage (18) so as to extend downwardly from an upper deck (14) into the through-passage. Alternatively, the Savonius turbines are rotatably mounted at opposite ends in the pontoons so as to extend horizontally above each other across the through-passage. The adjacent turbines are configured to rotate in opposite directions.
