A research team at Hong Kong Polytechnic created a 3D‑printed aerogel that uses only sunlight to evaporate and condense seawater into drinkable water. Producing just about 3 tablespoons in tests, it is the first of its kind that retains efficiency when scaled, offering low‑cost, off‑grid desalination.
