Abstract

A water powered energy generator (1) has a water powered energy capture device (6) and power extraction means (15, 22, 24) for extracting energy from the motion of the capture device (6). The capture device (6) comprises a flexible, endless, flap carrier (16) running along a path about horizontally spaced apart rotating support members (15) mounted on a base with the rotating support members (15) having substantially horizontally disposed rotation axes. The flap carrier (16) carries an array of buoyant flaps (18). Each flap (18) is transverse to the path of the flap carrier (16), attached by a pivot (20) at a pivot end to the flap carrier (16) and moveable from a first, water motion engaging position, where the flap (18) projects away from the path of the flap carrier (16), to a second position. In the second position where the body of the flap (18) is closer to the flap carrier (16) and the flap (18) projects from the pivot end in the direction opposite the direction of travel of the flap carrier (16).
