NOVELTY - The apparatus (100) has a wheel (110) coupled to one of multiple linkage members e.g. lever portion (102). Another wheel (112) is coupled to the former wheel via a tangential coupling element (134). A rotatable output shaft (138) is coupled to the latter wheel, where a flywheel (114) is operatively coupled to the rotatable shaft. An electrical generator (140) is operatively coupled to the rotatable shaft. The generator converts a rotational movement of the rotatable shaft into electrical energy, where the latter wheel rotates at a higher angular velocity than that of former wheel.    USE - Electrical generator apparatus for an electrical generator system (claimed) to convert an external actuation force applied by a vehicle i.e. hybrid gas-electric vehicles, traveling on a roadway into electrical energy that is utilized for powering various devices such as roadway lights, toll booths, and rest stops along interstate highways or freeways.    ADVANTAGE - The electricity generated by the apparatus is utilized for powering devices such as roadway lights, so that the demand load of the conventional power grid is reduced, thus reducing energy resources that are consumed by a power plant that supplies electricity to the power grid. The apparatus materially contributes to the efficient utilization and conservation of energy resources by making efficient use of the fuel that is consumed by vehicles, and reducing the demand load of power plants. The apparatus provides a valuable, additional source of electrical power that is unutilized by harnessing the kinetic energy. The apparatus reduces greenhouse gas emissions by reducing harmful waste products that are emitted from power plants, which predominantly burn fossil fuels to generate electricity. The apparatus does not use any complex fluid or hydraulic systems of any type, so that the manufacturing and maintenance of the electrical generator apparatus are simplified, and is less susceptible to fatigue failure. The apparatus for use on a roadway is easily integrated into a typical roadway without substantially disturbing the normal contour of the pavement so that motorists are not alarmed by the presence of the apparatus.
