NOVELTY - The energy conservation system (10) has a magnetic piston (110) that is placed along a primary longitudinal axis (108). A winding is arranged about the primary longitudinal axis. An actuating magnet (210) is placed in an orbital path about a secondary longitudinal axis to cyclically interact with the magnetic piston such that actuating magnet periodically exerts a force on the magnet piston to oscillate the magnetic piston along the primary longitudinal axis to induce an electrical current and voltage in the winding, and creates electrical energy.    USE - Rotational kinetic energy conservation system such as generator system, motor system, pump system, compressor system, engine system and electrical power transformer system for converting between kinetic energy and electric energy.    ADVANTAGE - The kinetic energy conservation system can be efficiently operated at smaller scales than traditional wind turbines, thus making them an important energy option for homeowners and small businesses. The system is scalable for larger installations by making larger rotational and linear kinetic energy devices, by coupling multiple stages of kinetic devices to a single water or wind driven rotational device, or by putting multiple units, each with a kinetic energy conversion system, on a single post or shaft. The housing is provided with openings permitting airflow to the respective sides of the piston, so that the air pressure buildup on ether side of piston is prevented from inhibiting the motion of piston. The openings also provide some cooling of the internal components of the linear kinetic energy conversion device. The piston is spaced away from inner housing so as to avoid loss of energy to friction between components. The efficiency of the conversion of the kinetic energy of the moving fluid into electric power is increased or improved by choosing appropriate lightweight materials for all components, as well as by scaling the magnetic components and choosing their relative polar orientations to optimize the efficient operation of the system. The magnets used in the energy conversion system are rare earth magnets, such as neodymium magnets, so that the desired strength combined with a low weight is provided. The piston approaches an end magnet which increasingly exerts a force on the piston to slow the piston down and ultimately reverse its direction of motion. This process is repeated continuously, resulting in an oscillation of the piston inside a winding that generates electrical energy.
