Reimagining Matter’: Nobel Laureate Invents Machine That Harvests Water From Dry Air

A groundbreaking new water-harvesting technology developed by Nobel Prize-winning chemist Omar Yaghi has the potential to transform access to clean water in the world’s driest and most disaster-affected regions. The device — capable of extracting moisture from even extremely arid air — could provide a sustainable source of fresh water without reliance on centralized infrastructure, offering hope amid worsening global water scarcity. �

A New Frontier in Water Technology
Yaghi, a professor of chemistry at the University of California, Berkeley and recipient of the 2025 Nobel Prize in Chemistry, unveiled the invention this month, describing it as a “science capable of reimagining matter.” The system uses advanced materials designed at the molecular level to capture atmospheric moisture and convert it into potable water, even in conditions where traditional technologies struggle.
Unlike conventional atmospheric water systems — which often require high humidity or significant electrical input — Yaghi’s technology operates using ultra-low-grade thermal energy. The units can be powered by ambient heat or residual thermal sources, eliminating the need for a constant electricity supply and allowing deployment in regions without established power grids.
Designed to resemble a 20-foot shipping container, the systems can produce up to 1,000 litres of clean water per day, according to company estimates. That volume could sustain a small community or serve as a lifeline in emergency scenarios where infrastructure has been disrupted by natural disasters or climate extremes.
From Desert Roots to Global Impact
Yaghi’s personal history underscores the invention’s significance. Growing up in a refugee community in Jordan, he experienced firsthand the hardships of life without reliable access to water or electricity — a memory he recounted at his Nobel banquet speech. That early struggle, he said, helped shape his determination to solve one of the most pressing challenges of the 21st century: water scarcity.
“In many places where I grew up, water was a precious and unpredictable resource,” Yaghi said. “This invention aims to make clean water more accessible and to reduce dependency on fragile supply networks that are vulnerable to drought and disaster.”

Real-World Applications and Humanitarian Promise
Experts emphasize that the technology’s potential extends beyond technical novelty. In areas devastated by hurricanes, droughts, or economic instability, water supply often becomes one of the earliest and most severe crises. In the Caribbean, where Hurricane Beryl and other storms have repeatedly damaged infrastructure, officials say the water harvester could offer a lifeline.
Davon Baker, a government official and environmentalist from Carriacou and Petite Martinique, described the system as a promising tool for resilience and recovery. “We’re still dealing with the legacy of hurricanes — storms that knocked out centralized systems and left communities reliant on imported water,” he said. “A decentralized solution that produces water from air itself could help us adapt to a future of more intense weather events.”
The invention also arrives amid alarming global statistics. A recent United Nations report described the world as entering an era of “global water bankruptcy,” with roughly 75% of the global population living in water-insecure conditions. Around 2.2 billion people still lack access to safely managed drinking water, and billions more experience severe scarcity for periods each year, the report said.
Sustainability and Climate Adaptation
Unlike some existing solutions such as desalination — which can harm marine ecosystems through concentrated brine discharge — Yaghi’s approach is engineered to be environmentally friendly. By leveraging ambient thermal energy and avoiding intensive electrical loads, the system aims to reduce carbon emissions and minimize ecological impacts.
“This technology does not require mega-infrastructure or heavy energy investment,” said a sustainable technology expert. “That sets it apart from traditional freshwater sources and makes it especially suited for vulnerable regions facing compound climate risks.”
However, many scientists caution that scaling the technology will require sustained investment, careful field testing, and adaptation to diverse climates. Large-scale deployment in extremely dry environments — where water vapor is sparse — presents engineering challenges that researchers will continue to evaluate.
Looking Ahead
With prototype units already in development, Yaghi and his team are working with partners to conduct pilot programs in regions most in need. The goal is to demonstrate operational viability and to refine how the systems can be integrated into community water strategies.
As climate change intensifies droughts and strains water resources around the world, innovations like Yaghi’s atmospheric water harvester provide a promising glimpse of how science might help mitigate one of the planet’s most urgent challenges. Whether in disaster zones, arid regions, or underserved rural areas, capturing water straight out of the air may soon become a critical tool in building climate-resilient communities.
