According to the "Daily Mail" website reported on March 23, Beijing time, scientists at the Massachusetts Institute of Technology (MIT) have developed a new technology that can generate moisture from the dry desert air, thus saving those living in bad conditions. Life in the desert climate. According to a recent report by MIT researchers published in Nature Communications, this technology can convert moisture in the air into water. As a result, 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 stated that the latest research can help people survive in the driest climate on earth. The technology was first mentioned in a paper in the journal Science last year. However, in the scientific community, both people are optimistic about the technology and some 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 issues raised at one time were clearly demonstrated this time. We verified the validity of those points of view."
The new product was tested in Tampa, Arizona, and the test results demonstrated that it has the potential to help people resist desiccation in the desert. The study wrote: "This system was created using a special type of material called the metal-organic framework (MOF), which extracts drinking water from the driest desert air with a relative humidity of only 10%. The current method of extracting moisture from the air is more demanding - the mist collection method requires 100% humidity, and the dew condensation collection system based on cooling requires a humidity of 50%, while also requiring a large amount 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 researchers to "observe the technology in a representative dry area and show that we can even obtain moisture below sub-zero. "In addition, the maintenance cost of this system is also lower than similar products. Researcher Sameer Rao said: "It has no moving parts and can operate in a completely passive manner in low humidity but sunny places."
“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 want to create a system that can generate a few liters of water. We want to see the water pour out," she said. The study writes, "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 equipment to supply water to individual households." Scientists during the testing process No impurities were detected in the water produced.
