Smart spongy device captures water from thin air
- Engineers from Australia and China created a porous material that uses sunlight to extract moisture from the atmosphere, as detailed in a February 2025 publication.
- The device uses refined balsa wood cubes treated with lithium chloride and iron oxide nanoparticles to absorb moisture at low humidity and release water when heated by the sun.
- Testing showed the device captures 2.5 milliliters per gram overnight and releases most water during daytime, maintaining efficiency from 30% to 90% humidity and temperatures from 5°C to-20°C.
- Dr. Junfeng Hou reported that the device was able to collect 94% of its potential water output each day, underscoring its promise for providing clean water in remote, dry, or disaster-affected locations.
- The device’s simple, low-cost materials and scalable production suggest it could provide sustainable drinking water solutions in emergencies and water-scarce regions.

Smart sponge device based on balsa wood captures water from thin air
A sponge-like device produced by engineers in Australia and China can capture water from thin air. The researchers say it could be used in arid regions of the world to collect water. A device, described in a paper published in the Journal of Cleaner Production, works in areas of low humidity where other technologies such as fog harvesting or radiative cooling struggle. With nine sponge cubes, each weighing 0.8 grams, 15 millilitres of water can …
