An element 7 displaceable in response to movement of the sea, in particular the rise and fall of the waves, has unidirectional means 29, 32 for transmitting movement of the element to a rotary shaft 3 whereby the shaft will be rotated in one direction only by displacement of the element. A cable 8 attached to the float 7 is wound around a reel journalled on shaft 3 and is anchored at 12 on the sea bed. <IMAGE> |
