Applying Compute-Proximal Energy Harvesting to Develop Self-Sustained Systems for Automobiles

A major cost, inconvenience, and source of failure for adding sensors and electronic accessories to automobiles is wiring the systems into the car's power supply. We propose an alternative approach, computer-proximal energy harvesting, which harvests power locally, so wiring is not needed. In this article, we provide an overview of the principles and empirical evaluations for harvesting energy in and around the automobile exploring the role that wind, light, vibration, and heat can play in this process. To better explore these concepts, we demonstrate two prototypes-A thermoelectric energy-based parking assistant, which is attached to the exhaust pipe, and a wind-powered external pedestrian display, which is anchored to the front bumper of a car.
