The video goes far beyond this piece here. What appears to be feasible is an evacuated tube system that does not need to be buried as one would assume, although that will be the case often. The proposed diameter is five feet which effectively allows seated passengers at two abreast. Any reduction in diameter lowers cost because the tube will be fully evacuated of almost all air.
Yet I think that a compression tube wall could be formed from cement to a much greater diameter. The actual sealant layer would be on the outside of the shell and press into the cement.
The difficulty could come with the transport shell itself which may be unable to resist expansion. In the event, work has been done on the five foot configuration and we can assume that turned out to optimum. We certainly can live with it for human and goods transfers.
The big idea is a tube system that connects Eurasia and Africa to North and
South America and operating at around 4000 miles per hour. It is suggested that this system would operate at a fraction of present cost regimes as it pays out. That is not implausible is reminiscent of Arthur C. Clark again.
In fact if the economics do work out, it is plausible to simply run parallel lines on the same right of ways in order to move bulk cargos such as grain and raw metals. This way every cargo and individual is at most several hours away and the costs and risk of air transport is hugely reduced.
China's building a high speed rail economy and could achieve a 1 to 1.2 billion person single city effect by 2040
SEPTEMBER 03, 2010
China has become the country with the fastest development, most complete systematic technologies, strongest assembly capacity, the greatest length of track, highest operational speed and the largest project scale of high-speed railways in the world. High speed rail seems to be providing a 1.0 to 1.5% annual GDP boost to regional economies.
could use low pressure maglev to create a 1 to 1.2 billion person megacity by 2040 and a 1.4 billion person megacity by 2050. A large number of high passenger and freight capacity maglev with 1500-2000 mile per hour speed could connect all of the cities in China by 2050. A UN report discusses the merging of cities into mega-regions and the is the largest megaregion is Hong Kong-Shenhzen-Guangzhou region in China, home to about 120 million people already. Super high speed rail will enable dense cities to physically connect for more productivity and economic growth. If China China proceeds down this path and achieves success there will be high speed rail links to the European high speed rail network, Japans high speed rail network and then connections across to the . Americas
China's high-speed railways are mainly in the three large economic zones, the Yangtze River Delta, the
In the same year, the GDP of the three zones accounted for 44 percent of the GDP of
The economy of Tianjin increased by more than 16 percent both in 2008 and 2009, much higher than the economic growth rate of all of China.
"One-city Effect" pushes the high-speed railway economy
Beijing-Shanghai High-Speed Railway to show 'dumbbell effect'
The track-laying work of the Beijing-Shanghai High-Speed Railway recently started after a track-laying machine quietly laid a 500-meter-long rail at the
The maximum speed of the Beijing-Shanghai High-Speed Railway is 350 kilometers per hour and can shorten the travel time for a distance of 1,318 kilometers between
"We can see on a map that the two ends of the Beijing-Shanghai High-Speed Railway connect
According to initial research and estimations, upon the completion of the Beijing-Shanghai High-Speed Railway, the "dumbbell effect" will lift the GDP growth rates of the regions along the railway by about 19 to 21 percentage points.
China's ability to capture even more economic growth with high speed rail increases the likelihood that China will develop even faster vacuum rail.
This is double the speed of current maglev trains, which enable a larger one city economic growth effect. Even more advanced vacuum maglev would enables speeds up to 12000 miles per hour. The double speed only costs 10-20% more than regular maglev.
According to Shen Zhiyun, academic member of CAS and CAE,
Each dot is about 5000 people and shows that almost all of china's population is in the eastern half of the country.
Going to 1500 mph in the 2030 to 2040 timeframe would enable about 90% of Chinas population to be 1 hour apart by low pressure maglev.
