Researchers from MIT and Berkeley have created a device to pull water from the air. Metal organic framework, or MOF, extracts water from the air. The metal in this MOF is zirconium and adipic acid. It can collect 2.8 liters of water over 12 hours at 20-30% humidity, which is very useful as it is difficult to extract water at such a low humidity. This sort of device will be very useful because 10% of the fresh water on Earth is contained in the atmosphere.

Key Takeaways:

• ten percent of the earths fresh water is in the air. Harvesting it will increase fresh water available.
• This is an inexpensive alternative to the traditional home dehumidifier.
• Metals combined with organic molecules have been proven to be able to capture moisture from the atmosphere.

“While the current MOF can absorb about 20 per cent of its weight in water, Yaghi believes other MOFs could potentially double that capacity to 40 per cent.”
