In its 2020 experiment, KSTAR improved the performance of Internal Transport Barrier Mode (ITB), one of the next generation plasma modes of operation developed last year, and was successful in maintaining the plasma state for a long time, overcoming the existing limitations of very high temperature plasma operation.
The ultimate goal of KSTAR is to achieve a continuous 300 second operation with an iration temperature above 100 million degrees by 2025.

Re: The race for nuclear fusion
The Korea Superconducting Tokamak Advanced Research (KSTAR), a superconducting fusion device also known as the Korean artificial sun, set the new world record by successfully keeping the plasma at high temperature for 20 seconds with an irrational temperature of over of 100 million degrees (Celsius). https://phys.org/news/2020-12-korean-ar ... -long.html

Wow, I'd almost have half a soft one!

Re: The race for nuclear fusion
It is not yet won. We know we'll be successful, but not when. It is known that the stabilization of the plasma is the great difficulty of the process. I have seen a lot of publications on the subject. Progress looks very slow and laborious.
There are alternatives to Iter, especially in the USA, but which do not seem to me to be more advanced.

Re: The race for nuclear fusion
TAE Technologies, the world's largest privately-held fusion company, has announced it will have a commercially viable nuclear fusion power plant by 2030, putting it years, if not decades, ahead of other companies in the world. fusion technology.
The California-based company has raised $ 880 million in funding for its hydrogen-boron reactor. This reactor is not a traditional tokamak or stellarator; instead, it uses a confined particle acceleration mechanism that produces and confines plasma.
All fusion technology has plasma, which mimics the extreme reactions that power all stars - that's what we emulate when we do fusion energy experiments. “Plasma is a weeping substance; the challenge of containing it is akin to holding Jell-O together with rubber bands, ”says TAE on its website. https://www.popularmechanics.com/scienc ... e-by-2030/

Re: The race for nuclear fusion
And, does it work, I mean, does it produce electricity? Is there any scientific proof or must we swallow?

Re: The race for nuclear fusion
Instead of producing steam to run a turbine, they intend to produce electricity directly ...Helion secures $ 2,2 billion to commercialize fusion energy
The tour de table was led by Sam Altman, CEO of OpenAI and former president of Y Combinator. Existing investors, including Facebook co-founder Dustin Moskovitz, Peter Thiel's Mithril Capital and renowned sustainable technology investor Capricorn Investment Group also participated in the round. The funding includes commitments of an additional $ 1,7 billion related to Helion's achievement of key performance milestones. Altman, leader of the round, has been involved in the company as an investor and chairman since 2015.
Fusion energy has been a burning dream for clean energy enthusiasts ever since the first controlled thermonuclear fusion reaction was carried out about 60 years ago. The technology promises all the benefits of current generation nuclear fission generators, at a fraction of the risk, with much less radioactivity in operation and with very little radioactive waste. There was a catch: Until now, it has been difficult to get the fusion process to generate more energy than it consumed to keep the reaction under control.
Helion, as a company, has focused less on fusion as a science experiment and more on a bigger question: Can their technology produce electricity on a commercial and industrial scale? https://techcrunch.com/2021/11/05/helion-series-e

Re: The race for nuclear fusion
It's “cold fusion” so, wouldn't there be a certain “Rossi” in it?

Re: The race for nuclear fusion
They are not very talkative (understandably) about the operation of their machines. compact fusion reactor de Lookheed martin.
Converting plasma directly into electricity is a very interesting way, it should probably involve something quite close to magneto hydro dynamic.
