Claim 11:
12. A system for converting kinetic energy, the system comprising at least:
(i) a mechanical apparatus comprising at least:
a sail element;
a mast connectable to the sail element, defining a main axis “z” about which the sail element and mast are rotatable, such that when the sail element is rotated by wind, it causes rotation of the mast and rotation of the mast rotates the sail element, wherein the sail element and mast are limited to rotate clockwise and counterclockwise about the “z” axis together within a limited rotation span which is smaller than 360 degrees:
at least one piston device comprising a piston housing and at least one piston; and
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;

(ii) a transmission subsystem movably connectable to the mast at one part thereof and to the at least one movable element at another part thereof, such that when the mast is rotated by the sail element in any clockwise or counterclockwise direction in respect to the “z” axis, the kinetic energy caused by the rotation of the mast is translatable into linear movement of the at least one movable element, in a first linear trajectory, which causes linear moving of the piston of the at least one piston device connected to the at least one moveable element, along the first linear trajectory, wherein the at least one moveable element and at least one piston are movable along a linear path which is angular to a plane that is perpendicular to a vector of gravitation, such that the at least one moveable element is also moveable in response to gravitational force applied thereto, at a second linear trajectory, which is opposite to the first linear trajectory, along the linear path, wherein the rotation of the mast and sail element causes a pull of the at least one moveable element in the rust linear trajectory and the weight of the at least one moveable element causes an opposite push of the at least one moveable element in an opposite second linear trajectory along the linear path, which causes reciprocal back-and forth movements of the at least one piston connected to the at least one moveable element, for filling and emptying of the piston housing of the at least one piston device, and, for creating fluid pressure; and
(iii) a power generation subsystem, connectable to the at least one piston device, which is configured for converting fluid pressure and/or changes in fluid pressure, caused by reciprocal movement of the at least one piston of the at least one piston device, into electrical power,
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.
