该养殖者可以从稀薄的空气中拉出水

《美国化学学会杂志》的一篇新论文解释了能够将薄空变成水的设备。该设备称为水收割机，来自加利福尼亚大学伯克利分校的一组研究人员。

收割机可以从每天2.2磅吸水材料每天从低湿度空气中收集超过5杯水。这些称为金属有机框架，是多孔的。这意味着您将能够生产足够的水来生活一天。根据世界卫生组织，您实际上会有盈余。

尤金·卡普斯汀（Eugene Kapustin），博士学位student at UC Berkeley, said in a YouTube video that was released by the university, ‘What it does is collect water from the atmosphere to very dry conditions and then releases it so we can harvest it as liquid water.’ The highlight of the process is the metal organic framework that is basically a pile of powder that is full of organic molecules and metals. The mixture is left out, overnight, thus allowing it to collect water molecules that are present in the atmosphere. These water molecules are able to attach themselves to the metal organic framework. Kapustin said, ‘You can imagine it’s like a sponge.’

将混合物放在水密箱中，并在提取水时使用热灯加热。水滴最终会紧贴侧面，并最终被收集为纯H2O。由于世界各地的水缺乏，科学家正在研究这个话题。该团队接近创建一个微波大小的收割机，您可以用来拉出空气的水。在加利福尼亚的莫哈韦沙漠进行了为期三天的现场测试中，收成的收成为24.7循环，并依靠太阳能电池板和电池供电。该设备能够创建近三杯纯H2O。

Omar Yaghi, the principal researcher, said in a prepared statement, ‘It is well known that in order to condense water from air at a low humidity—less than 40 percent relative humidity—you need to cool down the air to below freezing, to zero degrees Celsius, which is impractical. With our harvester, we are doing this at very low humidity without such cooling; there is no other material that can do that,” says Yaghi, who is also a UC Berkeley professor of chemistry. “This is not like a dehumidifier, which operates at high relative humidity. Some people say that 0.7 liters are not a lot of water. But it is a lot of water if you don’t have water.’
