Story summary

MIT engineers are testing a hydrogel panel device that extracts drinking water from air in Death Valley without power.
The device generates approximately two-thirds of a cup of water daily, targeting global water scarcity for over 2 billion people.
Hydrogels absorb humidity efficiently, attracting interest due to their low cost and energy efficiency.
Experts note challenges in atmospheric water harvesting, including high costs and low yields compared to traditional sources.
Companies like H2OLL and AirJoule are creating systems to produce larger water volumes in arid areas.
