> China has unveiled an extremely powerful "hypergravity machine" that can generate forces almost two thousand times stronger than Earth's regular gravity.
>
> The futuristic-looking machine, called CHIEF1900, was constructed at China's Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) at Zheijang University in Eastern China, and allows researchers to study how extreme forces affect various materials, plants, cells, or other structures, as the [3]South China Morning Post reports ... [Once up and running, it will allow researchers to recreate "catastrophic events such as dam failures and earthquakes inside a laboratory, according to the university."] For instance, it can analyze the structural stability of an almost 1,000-feet-tall dam by spinning a ten-foot model at 100 Gs, meaning 100 times the Earth's regular gravity. It could also be used to study the resonance frequencies of high-speed rail tracks, or how pollutants seep into soil over thousands of years.
>
> The machine officially dethroned its predecessor, CHIEF1300, which became the world's most powerful centrifuge a mere four months ago... It can generate 1,900 g-tonnes of force, or 1,900 times the Earth's gravity. To put that into perspective, a washing machine only reaches about two g-tonnes.

Flip the vector the other way and with some gravity-based stabilisers, maybe we could use it to hyper-launch objects/shuttles into space without the need to burn rocket fuel.

Sad to say it, but it could also be a new kind of artillery.

This thing has a very obvious dual use, for studying all those "hypersonic", that is, high acceleration military projectiles.

This is only megagravity, it is no where near ultragravity, let alone hypergravity.

A typical benchtop lab centrifuge (Score:2)
can easily break 10,000 g. NASA has at least one building-size centrifuge capable of spinning a human that runs at g of 20? 30? Not sure on that one.
This centrifuge looks like an interesting middle-ground size that probably has useful research purposes. But it’s not any sort of “centrifuge gap” to worry about. Kudos to the chinese for setting up interesting lab capabilities.
Forgive me, but why exactly? (Score:1)
You can squish something real good in a hydraulic press. You can put it in a diamond cell. You can do all sorts of things to it without spinning it up that would actually exceed internal forces generated by gravity loading alone.
Why the big spinny thing?

What is a g-tonne?

2,000 g's is definitely a ton of gravity.

Apparently, a capacity measure of these things.
> Among them, two main units have the maximum capacity of 1900 gt, the maximum centrifugal acceleration of 1500 g and the maximum load of 32 t.
So, this one can do max 1500 g for 1.26 ton, or 32t at 60g. It also says the largest outside of China are 1200 g*t.

What's the maximum gravity for something the size of a Saiyan? I know a guy who might be interested.
Re: (Score:2)
What is Saiyan? You simply divide 1900 tons by its mass (in tons) if it is less than or equal to 32 tons and there you are.

I heard he’s only interested if it can be fitted with a hyperbolic time chamber.

Assuming articles are correct it looks like it’s at a diameter of 49 feet or 15m. This is important because the loading is radial, not virtually parallel like under earths gravity at our scales. In order to be useful as a gravity simulator for high accuracy, you need the force of gravity to point the same way across your whole structure and when the radius of rotation starts to be less than roughly 10x the model width across rotation then the change in angle of gravity across the model starts to ne

Maybe, there's a piece in the Interesting Engineering website where they claim they'll be studying small models, roughly a ton in size. So, if it is a cube made from concrete, about 70 cm per side?
Re: g-tonne (Score:2)
Just a guess, but I assume it means it can support one tonne at 1G or 1 gramme at 1000G.

The correct terms are tonne-force (tf), Megagram-force (Mgf) or Megapond (Mp) [1]https://en.wikipedia.org/wiki/... [wikipedia.org]
