Claim 9:
10. A method of energy regeneration, the method comprising:
regenerating energy with a regenerative speed bump, which is installed on a road, from a passing vehicle,
wherein the regenerative speed bump bumper comprises:
a flat base portion,
sloped cover portion, wherein the flat base portion and the sloped cover portion form a cavity enclosed in the regenerative speed bump, and the sloped cover portion is flexible and configured to deflect downward upon application of force, and
a regenerative energy mechanism that is housed in the cavity of the regenerative speed bump and comprises:
a main gear having an axis of rotation and comprising an inner ring of ratchets,
a plunger positioned along the axis and configured to rotate the main gear by motion of the plunger along the axis, and
a pawl configured to allow the inner ring of ratchets and the main gear to rotate in only one direction,

wherein the plunger is mechanically connected to the sloped cover portion such that the plunger moves down along the axis when the sloped cover portion deflects downward.
