Problems solved by technology

Mechanical systems for generating electric power from the downward force of vehicles passing over a roadway typically involve gear mechanisms and other moving parts and are prone to wear and tear from the stress of forced downward movement in response to vehicles and forced upward movement when being reset.

Air compression systems, while generally somewhat more durable than mechanical systems, are not efficient in maximizing the amount of energy translated from the downward forces of moving vehicles to drive an electrical generator, due to friction and other losses.

These previously described systems, while in principle capable generating electrical power from the downward force of vehicles as they pass over a roadway, are inefficient in their ability to maximize the electrical power generated from each passing vehicle.

Prior systems do not effectively harness the full force of each vehicle.

Additionally, because vehicle traffic is typically irregular, there is an increased need in such a system to maximize the transfer of energy from each vehicle and store energy to provide a steady supply of electric power.
