You should think about how much raw product China ships out of that region around the world to produce meds.

This will devastate world markets if TGD fails.

Anyone who thinks 100+ million innocent people dying is no big deal isnt worth replying to. The people of China are no more to blame for their countries politics than any of us.

I posted this to the poliboard as well, but here's the video of what would happen if the dam breaks.

If real, that seems unsafe.

I take it you are blaming the people of Luxembourg for this?

I mean I am on that bandwagon

Its completely bullshite but I am on it

Not "real" simply an aberration.

If you do some measurement and simple math the sections I have circled would be offset by roughly 50'. The dam would have failed LONG before that level of deformation and that picture is from 2018.

Would be helpful to see a photo of the deflection:..other than a really crappy satellite image.

How? The CCP would be like muh...they have 1.4 BILLION mouths to feed, it wouldn’t even be a speed bump to their overall populace.
The optimum human population of Earth – enough to guarantee the minimal physical ingredients of a decent life to everyone – was 1.5 to 2 billion people rather than the 7 billion who are alive today or the 9 billion expected in 2050(Google)
The Rhinos, tigers, elephants...pretty much every living thing on this planet that’s edible is rooting against the dam.

Did I teleport back to 1980? We going to have food shortages? What a joke

We likely would not be able to visualize the deformation. Steel reinforced concrete structures are amazingly rigid. It would begin to become worrisome when the deformation is measured in centimeters. When crest or thrust block displacement starts getting to 50mm the engineers would start to sweat, this is why the poor sat images are so rediculous to point to as the condition of the dam. There are all sorts of potential failure modes. I have no idea what type of grout/water seals are in the dam and if they are keyed or not, whether they used rubble concrete and how the steel was tied in etc and etc. To have a good idea what is going on you really would need an FEA and a lot more correct information about how the dam was constructed.

The bottom line is by the time there are pictures that would make the average person say "that's gonna fail" it would likely have already failed or failure would be imminent. The West will likely not know anything until it actually fails if it does. Keep in mind it is holding back ~500 feet of reservoir depth and the water retention is enough to reduce the rotation of the earth by a demonstrable amount.

He might be taking about conservation of angular momentum. Water retention would theoretically increase the moment of inertia of the planet and therefore slow down the rotational velocity compared to if the water was released.

The thought that we can make something that would altar the angular momentum of the earth is laughable. When scaled to the same size, the earth is smoother than a cue ball.
