The EAST (Experimental Advanced Superconducting Tokamak) nuclear fusion reactor maintained a temperature of 158 million degrees Fahrenheit (70 million degrees Celsius) for 1,056 seconds, according to the Xinhua News Agency. The achievement brings scientists a small yet significant step closer to the creation of a source of near-unlimited clean energy.

The Chinese experimental nuclear fusion reactor smashed the previous record, set by France's Tore Supra tokamak in 2003, where plasma in a coiling loop remained at similar temperatures for 390 seconds. EAST had previously set another record in May 2021 by running for 101 seconds at an unprecedented 216 million F (120 million C). The core of the actual sun, by contrast, reaches temperatures of around 27 million F (15 million C).

Scientists have been trying to harness the power of nuclear fusion — the process by which stars burn — for more than 70 years. By fusing hydrogen atoms to make helium under extremely high pressures and temperatures, so-called main-sequence stars are able to convert matter into light and heat, generating enormous amounts of energy without producing greenhouse gases or long-lasting radioactive waste.

But replicating the conditions found inside the hearts of stars is no simple task. The most common design for fusion reactors, the tokamak, works by superheating plasma (one of the four states of matter, consisting of positive ions and negatively-charged free electrons) before trapping it inside a donut-shaped reactor chamber with powerful magnetic fields.

Keeping the turbulent and superheated coils of plasma in place long enough for nuclear fusion to happen, however, has been a painstaking process. Soviet scientist Natan Yavlinsky designed the first tokamak in 1958, but no one has ever managed to create an experimental reactor that is able to put out more energy than it takes in.

One of the main stumbling blocks has been how to handle a plasma that's hot enough to fuse. Fusion reactors require very high temperatures — many times hotter than the sun — because they have to operate at much lower pressures than where fusion naturally takes place inside the cores of stars. Cooking plasma to temperatures hotter than the sun is the relatively easy part, but finding a way to corral it so that it doesn’t burn through the reactor walls (either with lasers or magnetic fields) without also ruining the fusion process is technically tricky.

Anyone else getting spider-man 2 vibes

The JET in France got up to 150 million C for 5 seconds. I think we’re really gonna see fusion energy and power in our lifetime

[shimondhotekar]

Now make a planet where life is possible

Some haters will say China copied the tech from US 😅😅😅😅

China’s gravity is pulling me.. and I am falling on China

Deuterium is a hydrogen isotope, so the correct phrasing would just be hydrogen gasses

[Good_Luck_]

This is why we have so called heatwaves nowadays u see folks !

This takes the meaning “let there be light” to a whole other level.

As quick as they assembled that im sure it will be just a sturdy as the hospitals they built during the pandemic.

[myshinobi]

Ahh yes, the obligatory national artificial sun. The ultimate fashion accessory.

Can we send this to mars so that Elon musk can conduct terraforming?

[fishtoothLOLZ]

Blud is now making an real reactor core🔥🔥🔥🗣️🗣️🗣️

[wadeehrlich]

They said that they are able to run their artificial sun at 70 million degrees!? Compare to the real sun which its internal core is 15 million. Anybody here wanna challenge this!?

I thought this was a Lego build for a second
