a The digital picture of the scale-up downward desalination setup floating on the sea at Wu Kai Sha Pebbles Beach (Hong Kong). b Schematic illustration of the components in the scale-up downward desalination setup. (The dimensional parameters of the collector are 24 cm × 18 cm × 9 cm (length × width × height)). c The real-time temperature of the 3D concave-shaped solar evaporator and synchronized outdoor environment characterization. d The time-lapse characterization of the vapor condensation and freshwater collection procedure. e The time-lapse thermal distribution in freshwater collection procedure. f The 10-day freshwater collection performance of the scale-up downward desalination setup. g The ion concentration variation in real seawater before and after desalination. The dashed blue lines indicate the WHO standard of drinking water.
