1. An energy generating speed bump assembly, comprising:
a housing including a top surface, a bottom surface, a first wall, a second wall opposite the first wall, a third wall connected to the first wall and the second wall, wherein the third wall is perpendicular to the first wall, and a fourth wall connected to the first wall and the second wall and opposite to the third wall, wherein the housing includes three sections configured as an upper section adjoining the top surface, a middle section below the upper section and a lower section below the middle section, wherein the housing is mounted within a trench in a roadway;
a speed bump having a tapered side surface, a flat bottom surface, an arcuate top surface and an arcuate side surface, wherein the arcuate top surface is configured to extend from an upper end of the tapered side surface to the arcuate side surface, and the arcuate side surface is configured to extend from the arcuate top surface to the flat bottom surface;
a channel located within the housing, the channel having an opening configured to receive the flat bottom surface, the tapered side surface and the arcuate side surface of the speed bump, wherein the channel has a lower surface and tapered sides, wherein an angle of a first tapered side of the channel is configured to match an angle of the tapered side surface of the speed bump;
a spring having a top end mounted to the flat bottom surface of the speed bump, wherein the spring is configured to coil in response to a depression of the speed bump into the channel and to uncoil and return the speed bump to an undepressed configuration in which the arcuate top surface of the speed bump extends above a surface of the roadway;
a piston oil pump including a cylinder, a piston rod and a piston head configured to move within the cylinder, wherein a first end of the piston rod is mounted to the flat bottom surface of the speed bump and a second end of the piston rod is connected to the piston head, wherein a bottom end of the spring is mounted to an indented ring on an outside surface of the piston head;
a main oil reservoir connected to piston oil pump, wherein oil in the main oil reservoir is at atmospheric pressure,
wherein the piston oil pump is configured to pump oil from the cylinder into the main oil reservoir when the piston head is depressed by the speed bump and withdraw oil from the main oil reservoir when the spring uncoils and returns the speed bump to the undepressed configuration;
a compressed oil tank connected to the main oil reservoir and to the piston oil pump, wherein the compressed oil tank is configured to receive oil from the main oil reservoir when the piston head is depressed within the piston oil pump;
an oil turbine connected to the compressed oil tank, wherein the oil turbine is configured receive a stream of compressed oil when the piston head is depressed within the piston oil pump, wherein the stream of compressed oil is configured to rotate a turbine shaft of the oil turbine; and
an electrical generator connected to the turbine shaft, wherein the electrical generator is configured to generate electricity when the turbine shaft is rotated by the stream of compressed oil.
