Abstract

PVA-Based Porous Hydrogels In their Research Article (10.1002/adfm.202423371), Ady Suwardi, Jing Cao, and Zichen Gong devise a water-evaporation driven energy harvester that works even in the absence of sunlight. This was achieved by combining a thermoelectric generator with PVA hydrogel. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m/s wind), 1.71 mW (1.02 W/m2) power can be generated.
