Claim 14:
15. The system of claim 12, wherein the at least one sheave comprises:
a first sheave for rotatably connecting the mast to one end of the cable in a manner that enables the cable to become wrapped around the first ring connector;
a second sheave for forming a non-zero angle between a first part of the cable wrappable over the first ring connector and another part of the cable connected at an edge thereof to the at least one moveable element, wherein the at least one movable element is held angularly to the first part of the cable, such that the gravitational force is applied over the at least one moveable element acting as a weight that can be lifted by the upward movement of the at least one piston rigidly connected thereto, wherein the length of the cable determines a range of the rotation span of the sail element and mast.
