According to the “Daily Mail” website reported on March 23, Beijing time, MIT scientists have developed a new technology that can generate moisture from the dry desert air, thus saving those who live in harsh desert climates. According to a recent report by MIT researchers published in Nature Communications, this technology can convert moisture in the air into water. Therefore, the technology will be widely used throughout the world because The air in every part of the earth contains at least some moisture.
The MIT research team said that the latest research can help people survive in the driest climate on earth. This technology was first mentioned in a paper in the journal Science last year, but people in the scientific community have both It is full of optimism and some people are skeptical.
Professor Evelyn Wang was one of the authors of the original paper and also participated in the latest research. She said: 'This technology has received a great deal of attention and criticism. In the latest paper, All the questions raised at one time have been clearly shown this time. We have verified the validity of those views.'
The new product was tested in Tampa, Arizona. The test results demonstrated that it has the potential to help people resist desiccation in the desert. The study wrote: 'This system uses a metal-organic framework (MOF). ) The special types of materials produced can extract drinking water from the driest desert air with a relative humidity of only 10%. The current method of extracting water from the air is more demanding - the method of mist collection requires a humidity of 100%. Dew-collection systems based on cooling require a humidity of 50% and require a lot of energy for cooling.
Professor Evelyn Wang said that the device was placed on the roof of the Arizona State University building during the test, allowing the researchers to observe the technology in a representative dry area and to show that we can even obtain moisture below sub-zero. In addition, the system's maintenance costs are lower than similar products. Researcher Sameer Rao said: 'It has no moving parts and can be completely passive in low humidity but sunny places. Run. '
'We have now proved that this is indeed feasible,' Professor Evelyn Wang also pointed out, the next step is to improve the efficiency of this technology. 'We hope to create a system that can generate a few liters of water. We want to see When there is water poured out,' she said. The study wrote that 'These small initial test systems can only produce a few millilitres of water to prove that the concept is effective under realistic conditions, but the idea is to make enough for individual Home water supply equipment. ' Scientists did not detect impurities in the water produced during the test.
