gathering freshwater from that project and hurling it at the Tarim basin … Thats NAWAPA shit
yea, creating the artificial river is the part of the proposal that I haven't really checked numerically, and probably would be the hardest part, but it still feels doable within the timescale of 2 decades. Intuitively, it feels like they'd have a few pumping stations across Bangladesh, then one heavy-duty one to pump it up onto Tibet, and from there send it down a dynamited-carved river.
then there’s the fact we’ll have no idea just what the fuck any of this will cause—the dam & greening desert will fuck with rain patterns, the ocean currents, multiple ecosystems
not that much. There wouldn't be any less water in the ocean, so rainfall patterns would be unaffected. Ocean currents would be barely affected, it's a very small sliver of the entire Bay of Bengal, and a very shallow depth. The only changed ecosystem would be that within the reservoir, and some tiny local spots right next to it.
In exchange you get to create 2 Germxny's worth of green land in the desert. It would only add water to the atmosphere there which didn't exist before.
but since everythings fucked anyway who cares lets do it

that "heavy-duty pump" is going to be an enormous fucking project and the power it needs is astronomical. im talking a fusion plant.
and that simple canal is going through rough shit, its not like digging the all-american canal. and then there's the Kunlun to get over too.
Yes, it's a lot. But this is the country that built the biggest rail system on earth in a decade. I feel that it's doable, and that infrastructure experts should analyze the idea
this undertaking would make the rail system look like childsplay. the two largest lift systems ever devised (in terms of volume & vertical distance) serving the longest canal system ever built.
this sort of thing afaik has never been done. diverting water in a mountainrange to a different watershed is one thing, taking water from close to sealevel and pumping it up thousands of meters... even the passage from Tibet to the Tarim basin will be the world's largest.
Did some calcs and the cost of pumping that amount of water (the entire Brahmaputra system) up to the Tibetan plateau (18,000 ft) would be $2.3 trillion/year
Considering there are several other workarounds, like going around Tibet instead of across, or carving a river into the plateau which is only 5000ft elevated or something, this cost could be brought down to $600 billion/year.
The Bengal dam itself would cost $500 billion at most, judging from the North Sea dam estimates.
The cost of the infrastructure (aka artificial river) for transporting the water, based on the costs and water volume capacity of the Suez Canal (but scaled up to the Brahmaputra's size), would be $6 trillion.
So basically China would spend $6.5 trillion on this project, over a span of let's say 6 years to get the entire thing built. And then once built, It would take 6 years at $600B/yr of pumping water (or 12 years at $300B/yr, with India using the other half of the freshwater)
Would China be willing to sacrifice $1 trillion/year for 18 years to acquire a Germany?
this is necessarily back-of-the-envelope on both our parts but 1 trillion a year in energy cost alone appears to be more than the entire united states uses in a year :what-the-hell:
which is why i haven't emphasized money, this stuff is beyond legal fictions you're butting up against engineering and technological limits. i can't even get a ballpark on how many fusion plants you'd need to make this happen because the technology isn't close to that state.
and lets talk 'path of least resistance', going around is probably impossible. criss-crossing that many watersheds without messing them up (having to pipe/tunnel this enormous amount of water)would get absurd & you can't even avoid having to elevate up onto the Iranian plateau, and then up thru the Fergana valley---add to this the fact most of the regions you have to pass on the roundtrip are just as arid & would want that water just as much so why bother going so far?
the idea of burrowing through and avoiding lifting any more than you have to has been assumed in all my estimates. and it's still in the realm of magic engineering.
but speaking of exploiting a sudden surplus in freshwater from a project on the indian side of the himalayas, sending it to arid regions in India is infinitely more possible and less trouble. I'd modify the plan to (the still extremely ambitious target) Thar Desert, or completely fabricating some new intense agricultural operations on the river & lake and nearby. If you're worried for how China should benefit from that, they can get shipped produce from it

now that's what I like to hear.
