News on China's scientific and technological development.

Something tells me the same will happen with lithography and semi conductors.

Some milestones -

Atomic bomb
Hydrogen bomb
DF-5 ICBM
JL-1 SLBM
CNC machinery
Sunway TaihuLight supercomputer
Beidou Satellite System
DF-17 hypervelocity glider
Tiangong Space Station
Tianwen-1 Mars Mission
Maglev

I'm sure I missed a few; currently work in progress -

Lithography, EDA & semiconductors,
Quantum computing & communications
Electromagnetic gun
.......among other things

And today, debut in Qingdao at the CRRC test track, capable of 600 klicks an hour, so Beijing to Shanghai will just be 2.5 hrs.

Man the CRRC design looks amazing. I'm glad it didn't turn out like Japan's, with the ugly gigantic nose

I'm waiting for the 600kph test run.

While much of the Washington and US media are in a mode of self-serving and self-defeating when it comes to China, there are people who are clear-minded and cool-headed. Read the interesting post below.

Technological advance in China is rapid, broad in scope and, one might suppose (apparently) incorrectly, of interest to Americans. It is also easily discovered. Subscriptions are not all that expensive to Asia Times, NikkeiAsia, the South China Morning Post, and Aviation Week. The web is awash in tech sites covering everything from operating systems for smartphones to quantum computing. Reading of Chinese efforts, one gets a sense of motion, agility, vitality remarkable in a nation that in 1976, when Mao died, was the poorest nation on earth. America maintains a lead in many things, but seems to be almost asleep and resting on scientific virtuosity that is now lacking.

I hope the snippets below will give a sense of this. In many of the fields involved, such as quantum computing and fusion research, I am not remotely competent to judge their merit, but when they appear in internationally respected journals of physics, they are clearly taken seriously by those who are competent.

I'd expect US sanctions just for China having this disguised as human rights abuses. At least the Chinese are learning to make things look awesome.

This maglev seems to use different tech from japan´s maglev. Unlike Japan´s maglev, which uses EDS suspension, this train appears to use EMS suspension, which is the same tech used by transrapid, that china bought from germany. Both systems have advantages and disadvantages.



Beyond the question of if it can achieve the desired speed, the biggest issue is, will this train ever be comercially viable.

Why is there a question of IF? Is this speed (600km/h) some sort of beyond reach by anyone? Or just China in your mind? For reference, Shanghai maglev has reached 501kmph in 2003 using transrapid tech many decades old.

Would you ask the same question "will Japan's SCMAGLEV ever be commercially viable"? Actually, any such question regarding a public funded and operated service is false proposition. It is equal to ask "will compulsory education, medical care and pension be commercially viable?" In China and to some extent sino-sphere countries like Japan, these kind of service is never aimed to be money making, it is paid by the people through the tax. It is money from the left hand to the right hand, you don't expect making profit from yourself, do you?

Just so you know, 600 km/h is the designed operational speed which is lower than the top speed that it can achieve on a perfect testing track. I am expecting a top speed of well above 700 km/h.

This comparison is true only to a certain extent.

The japanese maglev has a maximum speed of 603 km/h (world record), and an operational speed of 500 km/h.



I havent seen any source that provides above 700 km/h maximum speed for the chinese maglev. Seems to me that 600 km/h is its maximum speed.
