The Need

Global water scarcity is a critical issue, with many regions lacking access to clean and reliable water sources. Traditional water harvesting methods are often energy-intensive and inefficient. There is a pressing need for innovative, sustainable, and energy-efficient technologies to extract water from the atmosphere, providing a viable solution for water-stressed areas.

The Technology

This elastocaloric water harvester, developed by OSU researchers, leverages the unique properties of nickel-titanium (NiTi) alloys, which undergo temperature changes when mechanically stressed. This elastocaloric effect is harnessed to cool and condense atmospheric moisture, efficiently converting it into liquid water. The system demonstrates superior water harvesting efficiency, requiring less power and offering enhanced thermoregulation compared to conventional methods.

Commercial Applications

• Portable water harvesting devices for disaster relief and military use.
• Agricultural irrigation systems in arid regions.
• Indoor cooling and dehumidification systems.

Benefits/Advantages

• Higher water harvesting efficiency compared to traditional methods.
• Lower energy consumption, reducing operational costs.
• Elastocloric cooling devices are small and less complex, perfect for individual users
