China's "artificial sun" set a new world record after superheating a loop of plasma to temperatures five times hotter than the sun for more than 17 mins

1. What the holy fuck is that?

3. Chinese "artificial sun" sets new world record

HEFEI, Dec. 31 (Xinhua) -- The experimental advanced superconducting tokamak (EAST), or the Chinese "artificial sun," has achieved a continuous high-temperature plasma operation for 1,056 seconds in the latest experiment on Thursday, the longest time of operation of its kind in the world.

The breakthrough was announced on Friday by Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP), who is in charge of the experiment conducted in Hefei, capital of east China's Anhui Province.

"We achieved a plasma temperature of 120 million degrees Celsius for 101 seconds in an experiment in the first half of 2021. This time, steady-state plasma operation was sustained for 1,056 seconds at a temperature close to 70 million degrees Celsius, laying a solid scientific and experimental foundation toward the running of a fusion reactor," said Gong.

The ultimate goal of EAST, located at ASIPP in Hefei, is to create nuclear fusion like the Sun, using deuterium abound in the sea to provide a steady stream of clean energy.

4. I get that thanks for the c&p. nt

2. I can't wait until they accidentally ignite the atmosphere! Oh, wait...

Yes, I can!

5. i don't understand what the video is. it looks like a rocket launch?

7. Nuclear fusion using superheated plasma as thermal conduit.

It’s the future of energy, unlimited energy, Sun energy on Earth.

Main technical problem as I understand it in the only amateur terms I can is containing the plasma in a bottle that won’t melt.

8. i know what fusion is. what is the video?

[Alexander Of Assyria]

9. Not contained plasma?

On edit…now have no idea what that is and now don’t care lol

10. So did it break out of the reactor?

From what I read ( and understood), the plasma has to stay in the loop to maintain temperature, but if it touches the side of the container it could break through.

6. It's a SpaceX launch

11. Just because they CAN do it doesn't mean they SHOULD be doing it

[MineralMan]

12. And that video has nothing to do with that.

13. That video is deceptive.

That’s a rocket launch, not a giant ball of plasma (well, insofar that it is a rocket exhaust flame, which is plasma-like). A tokamak is a very much contained magnetic field compression device. That they are able to achieve fusion for that long is A HUGE advancement, and what the world needs to provide power in the future.
