New WATER HARVESTER delivers fresh water from air

New WATER HARVESTER delivers fresh water from air 88

Researchers from the University of California, Berkley managed to successfully extract clean, drinkable water at very low humidity and at a low cost using their newly built next-generation water harvester.

Omar Yaghi, the James and Neeltje Tretter chair in chemistry at UC Berkeley and inventor of the technology said: “There is nothing like this.

“It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert.

“This laboratory-to-desert journey allowed us to really turn water harvesting from an interesting phenomenon into a science.”

In October 2017, scientists created a prototype water harvester, which they propped into the backyard of a tract home as the device sucked water out of the air using just sunlight as energy.

Their initial discovery led them to create an even larger water extractor machine, brining them closer to their goal of providing life-long clean and drinkable water to people living in water-scarce areas.

Mr Yaghi, a faculty scientist at Lawrence Berkeley National Laboratory, and his team are set to report the results of the water-collecting harvester’s first field test in the June 8 edition of the scientific journal, Science Advances.

The trial was conducted in Scottsdale, where the relative humidity drops as low as 8 percent a day.

Scientists have discovered a ground-breaking way to extract pure water from air

Despite low humidity levels, the harvester demonstrated its ability to extract water from even the most scarce places, after scientists added more of the machine’s water absorber – a highly porous material comprising of a metal-organic framework, or MOF.

Researchers estimate that the harvester’s current MOF (MOF-801), made out of the expensive metal zirconium, will be able to extract about 200 millilitres of water per kilogram of MOF.

Mr Yaghi also created a new MOF made out of aluminium, called MOF-303, that is almost 150 times cheaper and captures twice as much water compared to MOF-801.

This will enable scientists to produce a new generation of harvesters capable of producing more than 3 cups of water per day from one kilogram of MOF.

Mr Yaghi said: “There has been tremendous interest in commercialising this, and there are several startups already engaged in developing a commercial water-harvesting device.

“The aluminium MOF is making this practical for water production, because it is cheap.”

He added: “The key development here is that it operates at low humidity, because that is what it is in arid regions of the world.

“In these conditions, the harvester collects water even at sub-zero dew points.”

Mr Yaghi is awaiting his next field test, where he is set to test the alumnium-based MOF (MOF-303) in the Death Valley in late summer, where temperatures reach up to 43 degree Celsius in the day, with humidity levels as low as 25 percent.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 98

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 99

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 100

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
