In what might be the most interesting news of the week, the University of Texas at Austin, researchers have developed a sunshine that absorbs moisture from the air and turns it into pure water.

The technology is based on what scientists describe as "super sponges", hydrogels and hybrid polymeric hybrid materials designed to to hold large amounts of water. These hydrogels can also release water when heated. "We have developed a completely passive system where everything you need to do is to leave the hydrogel outside and it will collect water," said Fei Zhao, researcher and co-author of the study
. After about ninety minutes, under natural sunlight, water is released.
The new technology is based on the breakthrough of 201
"The new material is intended for collecting moisture from the air and obtaining clean water under sunlight, avoiding intense energy consumption." – said project manager Guihua Yu assistant professor of materials science and engineering at the Cockrell School of Engineering .Austin
Although the collection of water from moisture is not a new concept, most of the technologies that use this process are very energy intensive. The beauty of this new system is that it requires only solar energy.
In addition, the new device is com but is sufficiently effective to produce daily water production up to 50 liters per kilogram of hydrogel in accordance with the test prototype.This is enough to satisfy everyday household needs
Thus, the device could see many uses in the poorer regions or developing countries, where access to water is strictly limited, but this is not all.
The system can be used to improve current water harvesting methods, which makes them more efficient and less energy-efficient.
Yu and his team have already filed a patent, and research is published in the recent issue of the magazine Advanced Materials.
