It's an idea straight out of Star Wars: suck the humidity from dry desert air, and turn it into drinking water.
(Star Wars: Episode IV—A New Hope: "What I really need is a droid who understands the binary language of moisture vaporators.Vaporators? Sir, my first job was programming binary load lifters—very similar to your vaporators in most respects.")
Very similar to the vaporators in Star Wars's moisture farms, scientists have now used a box of gunmetal gray powder to pry moisture from the dry Arizona air by night...and deliver drinking water the next day.
The powder consists of tiny structures called metal organic frameworks, which contain even tinier pores to grab water.
"Initially, the water goes in and the first water molecules to go in and adhere to their internal surface, and make the pores more polar and so more water comes in."
Omar Yaghi, a chemist at U.C. Berkeley.

The powder-filled box is built inside yet another box. At night the larger box is left open, to let in the cool slightly humid air. But when it's closed in the morning, it helps trap heat—and evaporated water—inside. The water then condenses inside the larger box and trickles down to be collected—no cooler or power source needed.
The finding by Yaghi and colleagues is in the journal Science Advances.
It would take many truckloads of powder to sustain a community—every pound of the zirconium-based metal organic framework used here only squeezes three ounces of water from the air per day. But Yaghi is testing a much cheaper, more efficient aluminum-based powder. Which might just bring us a little closer to Tatooine. Technologically.

这是直接源于《星球大战》的一个想法：从干燥的沙漠空气中吸收湿气，然后将其转化成饮用水gl03,efX.5t7UC&y&。
（《星球大战4：新希望》）：“我真正需要的是懂水分冷凝机的二进制语言的机器人YT_02S^-Q#。冷凝机？先生，我的第一份工作是为二进制负载升降机编程，这在很多方面和您的冷凝机非常相似Vz%;I&|X2TX74%~F。”
与《星球大战》中湿地农场的冷凝机极为类似，现在科学家用一盒铁灰色粉末，在夜间从亚里桑那州干燥的空气中吸收湿气，然后在第二天形成饮用水fsR+3J45i(,(RLK8w。
这种粉末由被称为金属有机框架的微小结构组成，该结构包含更小的孔来吸收水分QiEtjd8ph]7WHl6。
