Energy Harvesting System from Speed Breaker for Sustainable Power Generation

Abstract

Exploration of alternate and sustainable power generating systems has become necessary due to the rapid increase in global energy consumption, the depletion of conventional fossil fuel resources, and growing environmental concerns. Creating an energy harvesting system from road infrastructure—specifically, speed breakers—to produce clean, renewable electricity is one creative strategy. This method makes use of the kinetic energy generated by moving vehicles over speed limiters, which would otherwise be squandered as vibrations and heat. Through the use of electromechanical devices like generators, piezoelectric transducers, or hybrid electromagnetic-piezoelectric systems, the vertical motion of vehicles is converted into rotational or compressive mechanical energy, which is then converted into electrical energy. The collected energy can be effectively stored in supercapacitors or batteries, which can then be used to power traffic signals, street lights, security systems, or even be connected to the local grid for communal use. Modern human life depends on energy, yet traditional energy sources are running out quickly.
