Claim 17:
18. A mechanical apparatus for conversion of kinetic energy, the mechanical apparatus comprising at least:
at least one piston device comprising a piston housing and at least one piston, linearly movable inside the piston housing;
at least one movable element connectable to an edge of the at least one piston of the at least one piston device, the at least one moveable element serving as a movable weight; and a transmission subsystem movably connectable, at one part thereof to a mast, which is connected to a sail element, and at another part thereof to the at least one movable element, such that rotations of the mast are translatable by the transmission subsystem into reciprocal back and forth movements of the at least one moveable element along a linear path,, wherein the transmission subsystem comprises:
a cable connected to the at least one moveable element at one end thereof and to the mast at another end thereof, where the connection to the mast is such as to enable the cable to be wrapped around the mast;
at least one sheave, having a rotatable rounded groove around which the cable is passed, the at least one sheave being located such as to form a non-zero angle between a first part of the cable and a second part of the cable that is attached to the at least one moveable element at an end thereof,
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 and lowered to lift and lower the at least one piston along the linear path for filling and emptying of the at least one piston housing.
