Claim 16:
17. A method for conversion of kinetic energy into electrical power, the method comprising at least:
providing a system for conversion of kinetic energy into electrical power comprising at least a mechanical apparatus that comprises at least a sail element, a mast connected to the sail element, at least one piston device, at least one moveable element connected to an edge of at least one piston of the at least one piston device for linearly moving thereof, the at least one moveable element serving as a moveable weight, and a transmission subsystem configured to transmit rotation motions of the mast into linear movements of the at least one piston and the at least one moveable element connected thereto;
pumping fluid from at least one fluid tank into at least one hydraulic accumulator, by using the at least one piston device of the mechanical apparatus, operably at least by wind power rotating the sail element, wherein the at least one piston device is directly or indirectly hydraulically connected to the at least one fluid tank and to the at least one hydraulic accumulator; and
converting fluid pressure generated in the at least one hydraulic accumulator to generate electrical power, by use of a power generation subsystem, configured for conversion of fluid pressure into electricity, wherein the at least one moveable element and at least one piston are movable along a linear trajectory 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 trajectory, wherein the rotation of the mast and sail element causes a pull of the at least one moveable element in a first linear trajectory and the weight of the at least one moveable element causing an opposite push of the at least one moveable element in a second opposite linear direction along the trajectory, 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,, 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.
