China maintains ‘artificial sun’ at 120 million Celsius for over 100 seconds, setting new world record

China broke the record by keeping the Experimental Advanced Superconducting Tokamak (EAST) by achieving plasma temperature at 120 million Celsius for 101 seconds and 160 million Celsius for 20 seconds, a major step toward the test run of the fusion reactor.

The Tokamak devise is located at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences. It is designed to replicate the nuclear fusion process that occurs naturally in the sun and stars to provide almost infinite clean energy through controlled nuclear fusion, which is often dubbed the “artificial sun.”

The achievement broke a previous record of maintaining the plasma temperature at 100 million C for 100 seconds. According to Li Miao, director of the physics department of the Southern University of Science and Technology in Shenzhen, it is a milestone in reaching the goal of keeping the temperature at a stable level for a long time.

“The breakthrough is significant progress, and the ultimate goal should be keeping the temperature at a stable level for a long time,” Li told the Global Times, adding that the next milestone might be to maintain the stability for a week or more.

Achieving a plasma temperature above 100 million C is one of the key challenges to harness the nuclear fusion. At the end of 2020, South Korea reached 100 million C for 20 seconds. The temperature at the core of the sun is widely believed to be 15 million C, meaning that the plasma at the device’s core will be seven times hotter than that of the sun.

The energy generated from nuclear fusion is the most reliable and clean energy, Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University, told the Global Times on Friday, adding that if the technology can be applied commercially, it will have huge economic benefits.

However, Lin cautioned that as the technology is still in the experimental stage, it still need at least 30 years for the technology to come out of the lab. “It’s more like a future technology that’s critical for China’s green development push.”

The experiment of EAST is part of the International Thermonuclear Experimental Reactor (ITER) facility, a global big science project second only to the International Space Station in size, and is being jointly constructed by China, the EU, India, Japan, South Korea, Russia and the US. Its success is significant to future peaceful utilization of international fusion. China devotes around 9 percent of its research and development.

    Fusion power now only 30 years away. HMMM what was it 30 years ago?

    From the 70’s until now they used to say “40 years to commercial feasibility”. That was said so often it was a standing joke among skeptics. Now “at least 30 years to come out of the lab”. Not exactly serious progress.

    Disappointing. When I saw the headline I was hoping this actually meant meaningful progress (like maybe 10 or 15 years to commercial feasibility).

    Oh well.

    NEVER going to be a practical, scalable electric source. A waste of time & $$$. Always in the future. Just send $$$$. LOL

    “NEVER going to be a practical, scalable electric source. A waste of time & $$$. Always in the future. Just send $$$$. LOL”

    The typical American uninformed opinion. Makati is the embodiment of US decline, that opines: “nothing works”.

    Now the facts:

    https://www.cleanenergywire.org/news/germany-marks-first-ever-quarter-more-50-pct-renewable-electricity

    “Germany marks first ever quarter with more than 50 pct renewable electricity”

    https://www.rechargenews.com/wind/denmark-got-50-of-power-from-wind-and-solar-in-2019/2-1-731183

    “Denmark got 50% of power from wind and solar in 2019”

    Both Denmark and Germany are rich countries. And with “rich” we mean the population, rather than an oligarchic over class.

    The Netherlands will have more than 100% renewable electricity by 2030, thanks to our unique position near the North Sea, with its shallow, windy waters:

    https://deepresource.wordpress.com/2021/03/07/overview-dutch-offshore-wind-effort-until-2030-and-beyond/

    Note this was only in 2020. We’re only getting started in Europe. And when this is all over we’ll have the technologies, patents and industries.

    Where China still wants to grow towards western levels, they are now building conventional power stations they will need to bring down again.

    America, that produces twice as much CO2 per capita as Europe, is missing the boat on all fronts, thanks to folks like makati and DT. They rather build carriers than renewable infrastructure. The US is unnecessarily running straight into Peak Oil 2026.

    Ah well, perhaps a blessing in disguise. Perhaps that a major energy crisis will provide the impetus to finally split up.

    They are making very well progress with fusion, but it is unlikely it will reach commercial scale within the coming decades. Perhaps next century, perhaps not. In principle, it works, as we are essentially living in a fusion universe. Oil, coal, solar, wind, biomass: all fusion derived.

    This century will be renewables though.

    The wind energy revolution began in Denmark, 50 years ago. Only now it is really taking off, with in Europe over 90% of new energy generating capacity coming from renewables.

    Don’t say never.

    Cloggie all of the % of so called renewable energy you tout is in the form of electricity. With the exception of rail transport, none of that % of energy is going into replacing diesel power in over the road trucking and ocean shipping. Not to mention all sorts of other heavy lifting machinery that relies on diesel power. Dream on my friend.

    “With the exception of rail transport, none of that % of energy is going into replacing diesel power in over the road trucking and ocean shipping.”

    Wrong.

    Shipping: most prominent candidate fuel is ammonia (hydrogen-based).

    So tell me DT, what is your vision for transport, now that you intend to snub renewables?

    Donkey + cart?

    I worked at a research institute for nuclear fusion in the 80’ies. Then it “needed 25 years before nuclear fusion could be practically used”. I’m glad to see it now needs another 30 years. I”m pretty sure it will need another 40 years by 2051.

    How would we classify someone investing billions of dollars in something like this?

  12. makati1 on Sat, 29th May 2021 5:19 pm 

    DT, Cloggie is a brainwashed renewables junkie. probably Laying in his mom’s basement, obviously sucking up the renewables Kool-aid propaganda by the barrel. (Pun intended) Probably on drugs. Rational? Nope! Refuses to see reality. Cannot think for himself. But then, that is typical in Western countries on the way down.

    I was educated (50s & 60s) when teachers taught their students to think and look at the whole picture. Now teachers are more concerned with their retirement, long summer holidays and teaching whatever the politicians tell them to. Dumbing down is the new normal in the West.

    Imagine they had used the resources on solar power and storage solutions.. Then we would already have safe relatively maintenance free fusion power

  14. makati1 on Sat, 29th May 2021 8:01 pm 

    peakyeast, you are so correct! Billion$ wa$ted over decade$ by fool$. A Trillion plu$? Never going to be practical.

    “Imagine they had used the resources on solar power and storage solutions. Then we would already have safe relatively maintenance free fusion power”

    “peakyeast, you are so correct! Billion$ wa$ted over decade$ by fool$. A Trillion plu$? Never going to be practical.”

    Makati typically missing the point, Peakyeast is making. Peakyeast supports the transition, Peakyeast thinks he doesn’t.

    Missing the point, pretty well defines makati. Makati an uneducated fool, with the intellectual shallowness of a soup plate, trying to impose his nihilism onto the rest of the world. For him, the fate of the world is one big fireworks, that will conveniently occur at the end of his life. Makati would love to see the world go under. #BeerAndPopcorn!
