You start with foreign components and build local capacity and experience as time goes by. In 10 to 20 years, all the foreign components will be replaced by local ones
10,000 dollars does not sound like a lot given the magnitude of this project.

Yes. Same model as used with high speed rail.
This is cool. Chinese researchers made a device that can generate electricity on the rise and drop of ambient relative humidity. Multiple such devices can be connected together to scale up in power generation. In experiments, a 6x6 "integrated array" of such devices lit up LEDs for hours "under one power generation cycle".
Chinese-made floating airship reaches world record altitude of 9,032 meters
Updated 15:28, 15-May-2022
A floating airship developed in China, named Jimu No.1, reached a new world record altitude of 9,032 meters on Sunday.
The airship ascended with a speed of 30 meters per second from a base camp at an altitude of 4,300 meters on Mount Qomolangma, the world's highest peak, located on the China-Nepal border, at 1:26 a.m. Beijing Time.
At 4:40 a.m., the airship hit 9,032 meters, above the mountain's peak of 8848.86 meters, setting a new word record.
Weighing 2.625 tonnes, the floating airship has a volume of 9,060 cubic meters and the vehicle attached to the bottome of the airship weighs 90 tonnes.

The observation apparatus on the airship is mainly used to record atmosphere composition data and the water vapor transmission process in space. The measurement data includes black carbon, dust, carbon dioxide and methane, which are key elements in studying environmental changes on the Qinghai-Tibet Plateau.
A 64-member team conducted the research. It is one of the 16 scientific research teams from China's "Earth Summit Mission 2022" scientific expedition.
The researchers are from three affiliates of the Chinese Academy of Sciences, including the Institute of Tibetan Plateau Research, the Aerospace Information Research Institute and the Changchun Institute of Optics, Fine Mechanics and Physics.
in my experience, I would say this group of folks are the higher quality of the tankers. So I treat them as a source of info, but still apply my own judgments. I also learn from this particular bunch (not csis in general) for their methodology/approach to this type of analytics.
