Researchers from the University of Texas in Austin understood how to transform everyday jets into a technology that draws clean water directly from the atmosphere.

The team used different organic materials to develop “Molecular functionalized biomass hydrogels“This extracts from drinking air from air using light heat, producing almost four gallons per day per kilogram of material, three times more than typical water harvesting technologies.

“This opens up a whole new way of thinking about the sustainable water collection, marking a big step towards practical water harvest systems for households and the small community scale,” said Professor Guihua Yu, who managed the research team.

Research is relevant today, since nearly 4.4 billion people have restricted access to drinking water, according to Recent studies. It’s almost 50% of the whole human population.

Extract from the air out of the air is not really newBut what distinguishes this approach is its use of natural materials that would otherwise end in discharges, which makes it safer and more respectful of the environment. The researchers successfully converted cellulose (found in plants), starch (foods such as corn and potatoes) and chitosan (shells) in high performance water harvesters.

“In the end, access to drinking water should be simple, sustainable and scalable,” said Weixin Guan, another researcher involved in the study. “This material gives us a way to draw from the most abundant resources of nature and make water from the air – anytime.”

Technology works through a two -step process. First, researchers attach thermoress groups to make materials sensitive to temperature changes. Then they add special molecules called “Zwitterionic groups” to increase the absorption capacity of biomass water.

The result is a hydrogel that works a bit like silica gel packets found in a normal dehumidifier, but with considerably better performance and a safer composition, using natural materials instead of synthetic.

During the field tests, the system turned out to be successful – a single kilogram of material produced up to 14.19 liters of water per day. The team says that similar technologies generally generate between 1 and 5 liters per kilogram every day.

Unlike conventional water harvesting systems which often rest on an eager energy refrigeration to condense atmospheric humidity, these hydrogels only need light heating to 60 ° C (140 ° F) to release their captured water – a temperature achievable with simple solar heating or waste heat by other processes.

This minimum energy requirement makes technology particularly promising for off -network communities and emergency situations where electricity could be unavailable.

Professor Yu’s team has been developing water -generating technologies for years, including systems adapted to extremely dry conditions and injectable water filtration systems. They are now working on production production and the design of practical devices for marketing, including portable water crops, autonomous irrigation systems and emergency drinking water devices.
