Energy Harvesting Heat Pipe (Low-grade Heat to Electricity Convertor)

This video is supplementary material for a paper on a novel energy harvester that converts low-grade heat (below 100 °C) into electricity. (DOI: 10.1016/j.enconman.2024.118607) The device is based on a single-turn pulsating heat pipe, made from a capillary glass tube bent into a square loop. Asymmetrical heating and cooling create a circulating, oscillatory flow that carries a spherical magnet fitted inside the tube. The passage of the magnet through two solenoids generates enough electrical power to run a quartz watch. Even at this early stage of development, the device operated with a temperature difference of less than 5 °C across the tube. In addition, its heat transfer capacity was comparable to that of conventional pulsating heat pipes, exceeding the thermal conductivity of copper by more than 25 times.
