flag MIT invents a device that collects drinking water from air using sunlight, but its output is limited.

flag MIT engineers have created a water harvesting device using hydrogel that can extract drinking water from air in arid regions like Death Valley. flag The device absorbs water vapor, condenses it, and collects it without needing power, relying solely on sunlight. flag While it can produce around two-thirds of a cup of water per day, critics argue it is costly and produces insufficient water, making it best suited for niche applications where tap water is unreliable.
