Electro gravity plates for generating electricity from passage of vehicles over the plates

An electro-gravity plate, comprising:

• a plate base;
• a plate body around the plate base;
• and
• an array of electro-gravity cells on the plate base and surrounded by the plate body, each electro-gravity cell comprising:
• a ramp body operable to be vertically displaced from an up position to a down position when a force is applied to a top surface of the ramp body;
• and
• an electrical generator that generates electricity from a displacement of the ramp body wherein each electro-gravity cell further comprises:
• a cell base;
• a cell body around the cell base, the cell body having a rest step that defines a counter bore opening above a main opening to the cell base, the ramp body being seated in the counter bore opening;
• and a spring-loaded mechanism that returns the ramp body from the down position to the up position.
