A team of researchers from Ohio State University has presented a device that allows for optimizing access to drinking water in places with severe shortages. This water harvester uses elastocaloric cooling technology based on nickel and titanium, and is able to extract more water from the air, in less time, and with only half the energy required.

The Ohio device offers an affordable, adaptable solution for communities facing water shortages. “ This technology could solve health and safety issues simply by making clean water more accessible, ” said John LaRocco, lead author of the study. “Its portable, compact design allows it to operate even in low-humidity environments, a radical change compared to current desiccant wheel systems.”
The new prototype is unique for its use of 3D printed materials and its ability to reduce the size and complexity of the equipment, making it easier to transport and operate. John Simonis, co-author of the study, explained that the system is adaptable and could meet the needs of a home or a community. “ Our design takes a modular approach that allows it to be optimized in size and adapted to the environment ,” said Simonis.
The United Nations estimates that only 0.5% of the water on Earth is drinkable. This device offers a new way to address the water crisis in regions affected by climate change or natural disasters, providing a resource that is both valuable and accessible.
