Continuous water purification using PNPG-F. a Schematic of a water collector based on a waterwheel structure. b The PNPG-F purifier is fixed on the gear of the waterwheel. Polluted water is fed by a pump. As the waterwheel rotates at a speed of 1 revolution every 10 min, clean water is continuously collected under solar irradiation. c A digital image of a single PNPG-F. d Water collection rate of the PNPG-F purifier immersed in seawater for 30 days. The results of the collection demonstrate the durability of the PNPG-F purifier. Insets are the typical water collection behavior on exposure to seawater for 1 and 30 days. e A simple device for the whole collection of water from transpiration and guttation
