Speed Breaker Energy Harvester Using Roller Mechanism

Increasing and renewing energy resources are needs of the times. Many efforts are spent to generate power from the speed breakers and many mechanisms are implemented for this goal. In this paper, these mechanisms will be reviewed and how the power is generated from each mechanism. In addition, this paper will provide and discuss an experiment of generating the power from a roller mechanism after brief description of the overall system implementation, connections and description. Results presented in this paper reveal that the implemented prototype roller mechanism has been able to produce up to 830 watts of peak power, which is sufficient for lighting signs, traffic signals and monitoring roads, especially when compared with the other mechanisms reviewed in this paper.
