Researchers develop solar system that turns air moisture into drinking water
Key takeaways
- At its core, the system is built around a sponge-like hydrogel made from lithium chloride and polyacrylamide.
- The idea is not entirely new, but durability has always been the sticking point.
- That issue now appears to have been largely addressed.

Add ARY News on Google AAResize Researchers at Stanford University and Massachusetts Institute of Technology have developed a solar-powered hydrogel system that pulls drinking water straight from the air, relying on sunlight as the driving force behind a process that could eventually change how water is produced in dry and water-stressed regions.
At its core, the system is built around a sponge-like hydrogel made from lithium chloride and polyacrylamide. It quietly absorbs moisture from the atmosphere when conditions are cooler, then releases it once exposed to sunlight, where solar heating triggers the trapped vapor to turn into water that can be collected and used.
The idea is not entirely new, but durability has always been the sticking point. Earlier versions of the material began breaking down after repeated use, limiting the system to roughly 30 solar heating cycles before performance dropped.
