| Summary: | This study proposes a novel thermoelectric harvester design for asphalt pavements, incorporating thermoelectric generators and phase change material. Through simulation and experimentation, a system was developed using PCM as a cold storage unit to maintain subterranean cooling. The design comprises an asphalt base holder and top and bottom plates for heat capture and dissipation, respectively. The exposed top plate harvests solar heat, while the submerged bottom plate connects to an H-shaped cooling element and a PCM container. This configuration leverages subterranean cooling and facilitates a significant temperature difference between the TEG plates. Consequently, the experiment observed a maximum attainable temperature difference of 42.22°C with PCM compared to 14.39°C without PCM, translating to a three-fold increase in charging efficiency, as demonstrated by a 5 V supercapacitor fully charged within 2.6 h. This novel TEG design offers a promising approach for self-sustainable energy harvesting from asphalt pavements. |
