A US-China collaboration has developed a solar-powered Desalination Tool that can produce 4-6 liters of clean water per hour. The prototype, about the size of a briefcase, utilizes thermohaline circulation, similar to the ocean's currents, to evaporate seawater and collect potable water vapor. The designers believe that a scaled-up version could sustain a coastal household year-round. With only 3% of the Earth's water being fresh, this technology has the potential to address water scarcity issues in coastal communities. The components of the desalination tool are designed for a 10-year lifespan.
