- MIT engineers have developed a superabsorbent gel that can soak up moisture from the air, even in arid regions.
- The gel is made of a cross-linked polymer infused with salt molecules. When the gel is exposed to water vapour, the salt molecules attract the water molecules and pull them into the gel.
- This means that a small amount of gel could provide a significant amount of water in arid regions.
- Even in very dry conditions, with 30% relative humidity, the material can pull vapor from the air and hold in the moisture without leaking.
- The water could then be heated and condensed, then collected as ultrapure water.
