What if water will be made from desert air?

Scientists from many countries are engaged in the discovery of methods of making water from the air. Omar Yogi of California University, Berkeley, USA has also devised the technique of making water from the air. He has prepared a powder resembling a sponge of metals, which absorbs water from its empty knuckles and collects it. With this one kilo powder, three liters of water can be stored by soaking in air in 12 hours. There is also some moisture in the most arid region of the land i.e. desert air. If water is removed by squeezing this moisture, it will be easier to live in the desert. Researchers had been trying to find a practical way to do this over the years.

Now Bharatvanshi Sameer Rao has developed a device at the Massachusetts Institute of Technology that can make pure drinking water even from the air of dry-to-dry deserts. It has been ground tested in Arizona's driest region. The scientists who prepare it believe that if the system starts working smoothly, it will prove to be very helpful even in extremely dry areas. This study has recently appeared in a journal called 'Nature Communication'.

There are many areas in the world, where people are getting two-four due to water scarcity. Many scientists and leaders have also predicted that the next world war will be fought due to water. But if a simple technique of making cheap water from the air is developed, then it is possible that the third world war should not be fought due to water. This new air-watering device has been designed with a 'Metallic Organic System' such as a metal-organic framework at the base.

MOFs are compounds containing metal ions. Water can also be made from this device with only 10 percent humidity of dry air, while the existing methods of extracting water from air such as fog and dew drops also require 100 and 50 percent moisture in the air respectively. Not only this, due to the refrigeration-based method of extracting water from this technique, a lot of energy is required, while the new equipment can be powered by the energy from the sun.

This device is not movable, it is a stationary device that easily absorbs solar energy. However, a large amount of sunlight is required to keep it operating. Currently, the device has a capacity of 250 liters of water throughout the day, but changing the metal in the device can make three times more water. With the energy collected from the sun, this machine can only move for one day and one night. Other small energy sources like biomass can also be used in this to keep it working continuously.

Israel's 'Waterzone' company has also invented air-to-water equipment. Through this device the temperature of the air with high humidity is reduced. As a result, the water molecules in the air start falling down. Company CEO A Kohani says that this device works to reduce air humidity. The water molecules that fall down are collected in a tank. After this, this water is flowed in a sieve machine, by this process, the remaining microorganisms and chemical contaminants related to this water are also removed. From this device 250 to 800 liters of pure drinking water is made in a day. The defense forces living in the inaccessible and dry areas of Israel make water from this device. Apart from this, Waterzone also supplies water in seven other countries. The cost of making one liter of water from this device is only one and a half rupees.

Pune-based company Tap in Air has done all these unique things. It has developed a technology that will make it easier for Indian kitchens to make water from the air. The company also showcased equipment for making air-to-water.

Company manager Anand Date claimed that we have developed a very indigenous technique of making water from the air. Through this, a man or woman can construct pure drinking water in their kitchen as per their need. The cost of this machine will be around 55 thousand rupees. With this, 30 liters of water can be made per day by consuming only one unit of electricity. However, US-made air-to-water utensils and they cost more, other they also eat more electricity. This device, priced at 15 lakhs, can manufacture only 48 liters of water by spending six units of electricity.

Scientists have been working on experiments to make water from the air for a long time. In 1839, a British scientist named William Robert Grove succeeded in breaking water into hydrogen and oxygen by an experiment related to the dissection of water. With this success he also hypothesized that if the same process of electrocution is done in the opposite way, then the addition of hydrogen and oxygen can generate electricity along with water.

With a view to realizing his imagination, he also experimented in this direction. They took two platinum leaves and attached them to a sealed bottle, which was loaded with hydrogen. Connected the second leaf to the same sealed bottle in which oxygen was kept. By placing both bottles in dilute sulfuric acid, an electric current actually flowed between the two electrides and resulted in the formation of water in the gas bottles.

Since the invention was recognized and famous, many scientists have been engaged in experiments to make water from air through simple and inexpensive technology. Now, in the twenty-first century, his dreams seem to be flourishing. In fact, scientists have found in studies that about 75 percent of the mass of all the elements present in the universe is just hydrogen. About 90 percent of the total atoms of all elements are just hydrogen atoms. Hydrogen is abundantly available in all stars, galaxies and other gaseous planets. All stars are formed from gaseous clouds made of molecular hydrogen.

After these facts are revealed, there is a possibility of life on Venus, the brightest planet in the solar system. From 1962 to 1978, the satellites released into space for studying Venus have shown that the surface temperature of the planet is above 450 degrees Celsius. In such a situation, development of life is impossible. But the area between its atmosphere, i.e between 40 to 60 kilometers in height, can contain microorganisms. Also, spots of sulfuric acid and light absorbing particles have also been found on Venus clouds.

Light-absorbing bacteria are also found on earth. These microbes can also be like algae. Actually, in this acidic environment, micro-organisms produce carbon dioxide and produce sulfuric acid. In the same way, sulfuric acid with carbon dioxide in Venus' clouds and acidic atmosphere are present in an invisible state in the form of water drops.

Clearly, now the way the efforts to make water in the world are accelerating, scientists are trying to make water from the large amount of sulfuric acid present on Venus, while exploring the possibility of settling on the planet Venus. . However, the gases and acids floating in the atmosphere from the earth to the space have intensified the campaign to create water.
