Musk: China’s progress in advanced infrastructure is 100 times faster than the US
Tesla CEO Elon Musk late Tuesday praised the high efficiency of a railway project in China, saying: "China's progress in advanced infrastructure is more than 100 times faster than the US."
The tech tycoon, whose company SpaceX successfully launched the world's most powerful operational rocket into space earlier this month, made the comment while retweeting a post of the British online newspaper Independent on Twitter, which contains a short video depicting how some 1,500 Chinese workers managed to upgrade a railway station by installing a new railway junction in less than nine hours.

The construction, which took place in Longyan City of southeast China's Fujian Province, began on January 19 at 6:30 p.m. local time and finished by 3:00 a.m. the following day. It was meant to connect a newly-built line with three existing railway lines. Seven trains and 23 excavators were used in the project.
Musk's tweet has been widely shared and gained over 1,300 comments so far, many of which echoing his view. @EcoCrypto1 replied: "Absolutely amazing the teamwork that is put into this!", and @brandonholma said: "I work for a light rail system in San Diego and we've been building 1 new station for over 6 months."
In following tweets, Musk went on pointing out the problems of inefficiency and high costs in some of the US infrastructure projects, such as the elongation of the New York subway, saying the root cause, in his opinion, lies in "an exponential growth of bureaucracy" and "a self-serving private sector consultant industry" earning profits on project cost.

"The system of incentives is messed up," he added.
It is not the first time for people around the world to be amazed by the "China speed."
In 2015, a Chinese development company built a 57-story tower in 19 days in Changsha, Hunan Province. In June 2017, some 200 diggers demolished a major overpass in Nanchang, Jiangxi Province in just eight hours.
Both stories were widely reported by global media, with people around the world in awe of the speed as well as how well organized these jobs had been.

Via Martian from Pakdef. Slowly they are chipping away at western chip technology monopoly.
China has reached a milestone. Xi'an UnilC Semi is selling its own designs of DDR4 DRAM chips and modules.
"DDR4 SDRAM is the abbreviation for 'double data rate fourth generation synchronous dynamic random-access memory,' the latest variant of memory in computing. DDR4 is able to achieve higher speed and efficiency thanks to increased transfer rates and decreased voltage."
In simple English: DDR4 is the fastest computer memory available.
"DDR4 memory technology is up to twice as fast and delivers 50% more bandwidth and 40% more energy efficiency than DDR3 technology when it was introduced."
----------
"Xi’an UniIC Semiconductors, a memory producer based in China, has started to sell DDR4 DRAM chips and modules that were developed and made in-house. This is the first time when a China-based company develops its own DDR4 memory chips.
...
Xi’an UniIC’s DDR4 lineup includes 4 GB and 8 GB SO-DIMMs, 4 GB and 8 GB UDIMMs as well as a 4 GB UDIMM with ECC, all rated for data transfer rate of 2133 MT/s with CL15 15-15 timings at 1.2 V (according to Xi’an UniIC’s DDR4 product decoder). All the DIMMs are based on Xi’an UniIC’s own DDR4 memory chips featuring 4 Gb capacity. The modules and the chips are not meant to offer breakthrough performance levels and are probably aimed at various inexpensive PCs, most of which will be sold in China."
I hope this will bring time ram prices and affect SSD prices as well. Computer components have rise so much

This is a good idea. In the mean time housing prices are have sky rocketed so much in Silicon Valley that many Google, Facebook, and Apple workers couldn't afford to live there any longer.

Chinese submersible goes deep in Indian Ocean
China has been sending its cutting-edge AUVs to survey geology and look for resources
By ASIA TIMES STAFF MARCH 6, 2018 6:10 PM (UTC+8)
The Chinese unmanned submersible Qianlong-2 has been descending to new depths in the Indian Ocean, wrapping up five dives during its journey on the second section of the country’s 49th ocean expedition. The AUV is capable of diving to 4,500 meters below the surface.
Qianlong, meaning “diving dragon” in Mandarin, is capable of operating without monitoring from its mother vessel while carrying multiple-acquisition sensor modules including seabed cameras and magnetic surveyors to map terrain in three dimensions as well as geomagnetic features of the seabed, according Xinhua.
Measuring 3.5 meters in length, 1.3 meters in height and 70 centimeters in width, the Qianlong-2 cruised 325 kilometers during its 141 hours underwater in the second section of the expedition, which ended on Monday.

Its mission was to detect basalt and marine organisms, polymetallic sulfide deposits and other deep-sea mineral resources in the investigation area of about 300 square kilometers in the southwest Indian Ocean.
“The Qianlong-2 is so automated that its mother vessel can sail somewhere else for other missions and come back later and collect the submersible from water,” said lead engineer Tao Chunhui.
The Qianlong-2 had its maiden dive in October 2014, also in the Indian Ocean.
Meanwhile, the China Oceanic Administration said all the surveys were carried out in high seas in the Indian Ocean, stressing the scientific significance of the young ocean and its unique maritime geomorphic profile and abundance of resources.

In January, China and Pakistan conducted a joint multi-disciplinary investigation of the Makran Trench in the northern Indian Ocean.
Yet New Delhi has been keeping a wary eye on the increased presence of Chinese vessels, submarines and submersibles, either military or for scientific research, in the vast sea that is a strategic buffer and a new front of geopolitical rivalry.
The fact that Chinese ships plying Indian Ocean routes so far from their home ports and bases in displays of blue-water capabilities is a source of consternation for India, as its own naval and research ships can barely limp into far-flung international waters by comparison.
New Delhi has lodged a number of complaints with Beijing about the latter’s perceived breaches of its marine territory and interests.
The first sea trial of the Qianlong-3, an upgraded variant, is scheduled for April.

Chinese EV Battery Giant Zeroes In on Its First Europe Plant

From
The Chinese supplier of electric-vehicle batteries that’s planning a local factory with enough capacity to surpass the output of Tesla Inc. has set its sights further: Europe.
- CATL about to pick site in EU to take on LG Chem, Samsung SDI
- Germany, Poland, Hungary said to be countries being considered
is close to picking one of three sites in the European Union for its first overseas plant, Chairman Zeng Yuqun said in an interview. The company is exploring Germany, Hungary and Poland for the plant, according to a person familiar with the plan who asked not to be identified as the information isn’t public.
“We see a big opportunity in Europe,” Zeng said on the sidelines of the National Committee of the Chinese People’s Political Consultative Conference in Beijing. “Korean companies, using a low-price strategy to compete with us, haven’t made much technological progress in the past two years, while we have managed to grow fast and surpass them.”
The expansion in Europe comes on top of a plan to build a factory in the company’s home base of Ningde, Fujian, that would quintuple its production capability and make it the world’s largest EV battery cell maker. A pending $2 billion initial public offering would help finance the construction of the plant in China. The European facility would supply major carmakers in the region, including BMW AG, Zeng said on Monday.
CATL, as the company is known, is one of the manufacturers spawned by China’s aggressive push for cleaner air and fewer oil imports. The company, which already sells the most batteries to the biggest electric-vehicle makers in China, is looking for a location in Europe with the lowest cost and the demand for electric vehicles on the continent would dictate the capacity, Zeng said.
Volkswagen AG has already agreed to use CATL batteries in models it makes in China. That could lead to more overseas contracts for the cell maker and a shot at a chunk of the 50 billion euros ($62 billion) VW plans to spend to power its EVs over the next decade or so. Nissan Motor Co. has also chosen CATL for a new EV model it plans to introduce in China soon, people familiar with the matter said, asking not to be named. Representatives at Nissan and CATL declined to comment.
The company will open a sales office in Japan in May, Liang Chengdu, dean of CATL Research Institute, said last week in Tokyo. Japanese carmakers including Toyota Motor Corp., Nissan Motor Co. and Honda Motor Co. have all said they are considering CATL batteries for their local EVs in China. CATL also opened a sales office in the U.S. last year.
