Nope. Typical a troller, provocator, or propagandist, far from a think thank analyst.

China's large-scale cryogenic refrigeration technology, which is fundamental for important industrial sectors such as aerospace and hydrogen energy, has made a major breakthrough, with the ability to cool down -271C with hundred-watt level power.

China's major scientific research project for developing the large-scale cryogenic refrigeration system in liquid helium to superfluid helium temperature range has passed experts' appraisal, Xinhua reported on Saturday. This project is supported by the Ministry of Finance and undertaken by the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (TIPC-CAS).

China can now develop large-scale cryogenic refrigeration equipment with a liquid helium temperature of 4.2K (-269 C) kilowatt level and superfluid helium temperature of 2K (-271C) hundred-watt level, a milestone which has broken technology monopoly by the developed countries, and made China's large-scale cryogenic refrigeration technology reach the global advanced level, according to TPIC-CAS's official website.

Large-scale cryogenic refrigeration equipment from liquid helium to superfluid helium temperature range is an indispensable core foundation for strategic fields, such as aerospace and hydrogen energy.

China's large-scale cryogenic refrigeration equipment has relied on imports for many years, TPIC-CAS's official website reported, noting that foreign countries have prohibited the key core component and refrigeration equipment used in special fields from exporting to China.

The hundred-watt large refrigerating machines have been successfully put into operation in several industries, such as accelerators and nuclear fusion, according to Xinhua, adding that the research project in developing a large-scale cryogenic refrigeration system has also driven the rapid development of relevant industries, including cryogenic heat exchangers and cryogenic valves. The low-temperature industry cluster with complete functions and clear division of labor has been initially formed now.

China's first underwater data center unveiled in Zhuhai
2021-01-13 09:59:40 Ecns.cn Editor : Luo Pan

(ECNS) -- China's first undersea data center (UDC) was unveiled in Zhuhai, Guangdong Province on Sunday.

The UDC project involves installing Internet facilities like servers in airtight pressure vessels with excellent cooling performance under the ocean surface.

These facilities are powered by subsea composite cables and then transmit data to the Internet.

UDC has the advantage of energy and resources saving by cooling off Internet facilities with a huge amount of circulating seawater.

The biggest bottleneck to data center development is energy consumption. It consumes too much power and cannot be halted for a second. Seawater can be used to reduce energy consumption by about 30 percent, said Xu Tan, vice president of Highlander.

A big data center, with an annual economic volume exceeding 300 billion yuan, is vital to new infrastructure, Xu added.

Currently, most big data centers are built on land, occupying a large amount of space and consuming excessive power and cooling water.

Therefore, it is scientifically most effective to further utilize marine space and deploy China's coastal data centers in offshore waters, Xu said.

UDC is primarily powered by urban industrial power, supplemented by renewable energies like offshore wind, solar and tidal energy, and features low cost, short latency, high reliability and safety.

It is calculated that servers contained within the data center could prove up to eight times more reliable than their dry-land counterparts.

China starts building world's first commercial undersea data center

China has commenced work on the world's first undersea commercial data center, with completion expected in five years, the state assets regulator in Hainan Province announced on its website on Monday.
