Design of power generation and energy storage device for road speed bumps

Can speed bumps generate power?

This study explores the practicality of power generation from road speed bumps by harvesting the energy of moving vehicles using a mechanical speed bump design with rack-andpinion mechanism and spring system. It includes design analysis and prototype fabrication.

What is Speed Bump based mechanical energy harvesting?

Based on the existing techniques for energy harvesting, in this paper, we proposed a novel speed bump based mechanical energy harvesting (MEH) mechanism capable of generating electrical power not only in the loaded but also restoration modes. The objective of the proposed MEH system is given as;

Can a traffic energy-harvesting device harvest vehicle energy when passing over a speed bump?

A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies used in existing TEHDs. Moreover, an estimation of the energy that could be harvested with the different technologies and their cost has been elaborated.

What is a movable semi-circular Speed Bump?

A movable semi-circular speed bump collects the waste kinetic energy of the traffic moving on the road. Hence, the electrical equipment installed on or beside the road can be powered by MEH. When a car runs over a speed bump, it is displaced downward by the weight of the vehicle.

Can piezoelectric power generation device be used in road traffic environment?

This paper presents a design scheme for the applicability of piezoelectric power generation device in road traffic environment, which overcomes the problem of limited application due to the existing technology inapplicability to the complicated and changeable road traffic environment.

How is a speed bump based meh prototype made?

Fabrication and assembly The fabrication and assembly of the speed bump based MEH prototype is shown in Fig. 7. The semi-circular shaped bump profile is fabricated from a piece of metallic sheet, which is passed through a rolling press and then welded, to obtain the requisite shape.
