Abstract
A vertical twin rotor water turbine apparatus and method for extracting energy from a flow of water is described herein. The described apparatus delivers favorable performance by virtue the operation of a novel configuration of a plurality of central cores with at least one blade member extending from each core and flow directors to increase the effectiveness and efficiency of said device.
Claims4
A blade for use with an energy-generating turbine, the turbine having a central rotating member, the blade having a ram surface and a lift surface, the blade comprising:
- an inner portion proximate the central rotating member;
- a central portion beginning at a distal end of the inner portion;
- and,
- an outer portion beginning at a distal end of the central portion and terminating in a sharp tip;
- wherein the central portion is curved to induced lift to the lift surface of the blade;
- and
- wherein a curvature of the outer portion at the tip substantially corresponds to a curvature of a circular path travelled by the tip of the blade during rotation of the central rotating member.
