Abstract: Systems methods and apparatuses for conversion of kinetic energy, which may include: a sail element; a mast; piston device(s) each comprising a piston housing and a piston; movable element(s) connectable to an edge of each piston; and a transmission subsystem movably connectable to the mast and to the movable element(s). The moveable element(s) and piston(s) are movable along a slopped linear path. Clockwise and/or counterclockwise rotations of the mast, caused by wind, are translatable into linear movements of the moveable element(s) and the piston(s), in a first linear trajectory, where the weight of the moveable element(s) causes opposite linear movement of the moveable element(s) and piston(s) in a second opposite linear trajectory, which causes reciprocal movements of the piston(s) causing fluid pressure by emptying and filling of a fluid therefrom and thereto. The mechanical apparatus can connect to a power generation subsystem, configured for conversion of fluid pressure into electrical power.
