Did A Korean Research Team Just Find The
"Holy Grail" Of Water Desalinization

Could the holy grail of turning salt water to drinkable water finally be
A new report from Interesting
Engineering seems to suggest that could be the case -
detailing a new nanofiber membrane, developed by Yunchul Woo and his
team at the Korea Institute of Civil Engineering and Building Technology, that
appears to be "stable in the long term" for desalinization. And it
can be done "in minutes", the report says.
Membranes had been used in the past, but there is often a
challenge in keeping them dry for long periods of time. When they become wet,
their filtration characteristics become ineffective and large amounts of salt
can pass through.
Woo's team has created a membrane "made of nanofibres that
have been fabricated into a three-dimensional hierarchical structure" by
using a technology called "electrospinning". This new membrane is
said to be highly water repellant.
Water from one side is heated and allows water vapor to pass
through the membrane, which is then condensed on the other side. The process is
called membrane distillation.
"Since the salt particles are not converted to the gaseous
state, they are left out on one side of the membrane, giving highly purified
water on the other side," the report says.
It also notes that the researchers used silica aerogel in
their membrane fabrication process.
Upon testing the technology for 30 days continuously, they found
the membrane filtered out 99.9% of salt without wetting problems.
Desalinization is the obvious answer to the global issue of over
785 million people lacking clean drinking water. Up until now, scientists have
been unable to figure out a quick, cost-efficient and effective way to turn
salt water into drinkable water.
Fresh water only accounts for 2.5% of the total water available
on Earth, the report notes.
World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 · A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling. “You barely feel that the patient is 3,000 kilometers away,” he said.
Visualizing The Power Of The World's Supercomputers BY TYLER DURDEN FRIDAY, JAN 21, 2022 - 04:15 AM A supercomputer is a machine that is built to handle billions, if not trillions of calculations at once. Each supercomputer is actually made up of many individual computers (known as nodes) that work together in parallel. A common metric for measuring the performance of these machines is flops , or floating point operations per second . In this visualization, Visual Capitalist's Marcus Lu uses November 2021 data from TOP500 to visualize the computing power of the world’s top five supercomputers. For added context, a number of modern consumer devices were included in the comparison. Ranking by Teraflops Because supercomputers can achieve over one quadrillion flops, and consumer devices are much less powerful, we’ve used teraflops as our comparison metric. 1 teraflop = 1,000,000,000,000 (1 trillion) flops. Supercomputer Fugaku was completed in March 202
Beijing Orders Alibaba To Dump Media Assets That Rival China's Propaganda Machine BY TYLER DURDEN MONDAY, MAR 15, 2021 - 07:30 PM Beijing is reviving its crackdown on the country's biggest tech firms, reminding the world that the CCP is still focused on neutralizing any and all threats to its control of the Chinese economy and its people. Even after amending China's official ideology to include entrepreneurs among the protected classes represented by the CCP (in addition to workers, farmers and soldiers), Beijing, with President Xi at its center, has apparently decided that Chinese tech firms won't follow the American model after all. Instead, their growth and competitive capabilities will be curtailed for the sake of stability at home. After Tencent was censured and strict new requirements were officailly imposed on Alibaba-owned Ant Group that will prevent the company from growing , the Wall Street Journal reports that next up on Beijing's to-do lis
