Piezoelectric Roads: Can We Generate Power from Traffic?

This podcast episode discusses piezoelectric roads, an innovative technology that aims to generate electricity from the mechanical stress of passing vehicles. It explains the science behind piezoelectricity, where certain materials produce an electrical charge when deformed. The document outlines how these materials are embedded in roads and the process by which vehicle pressure is converted into usable energy. While the potential applications, such as powering streetlights and charging electric vehicles, are highlighted, the source also addresses the challenges related to efficiency, cost, and durability that need to be overcome for widespread adoption, referencing pilot projects and research globally.
