What exactly is a tokamak? 🤔
It's a machine designed to harness fusion, the process that powers the stars. At its core: a doughnut-shaped vacuum chamber where hydrogen becomes plasma at 150 million °C, ten times hotter than the Sun's core, confined by massive magnetic coils.
ITER, in France, will be the largest ever built.

#^Nestabilita plazmatu by mohla tokamakům pomoci potlačit turbulenci
Vědci v zařízení DIII-D v Kalifornii získali první experimentální důkazy, že některé nestability plazmatu nemusí fúzi jen škodit. Vlny známé jako Alfvénovy vlastní módy mohou vyvolávat proudy a proudění, které vytvářejí smykový tok potlačující turbulenci. Díky tomu se v jádru plazmatu lépe udrží teplo a vznikají příznivější podmínky pro slučování jader vodíku. Měření odhalilo zhruba pětiprocentní změnu faktoru bezpečnosti během 20 milisekund, což odpovídá předpokládanému samoregulačnímu mechanismu. Praktické využití tohoto jevu je ještě vzdálené, ale výsledek může pomoci zlepšit konstrukci a řízení budoucích fúzních reaktorů.

This morning I am thinking about all of the scientific terminology related to fusion reactors I added to my personal dictionaries lately and about properly spelling "enshittification" with two t's rather than one.
Because I'm a bit of a cybersecurity wonk I often use task specific browses and accounts, some of them from fully walled off disposable one time use virtual machines, and I get to see the very weird assumptions the fiends at the monopolies make based on limited information provided to their ubiquitous surveillance systems.
While I do not need a vast array of personal spectroscopic lab equipment starting at the low, low, discount act-now price of $25,000 and going up from there, I do have a YouTube/Google account that runs to ads hawking that sort of equipment and very nice high resolution digital microscopes, which granted might be very useful kitchen accessories given that the food supply is no longer inspected or safe, but are quite out of my financial reach no matter how cool it would be to examine my salads before they send me to the ER. The people at the Googlag seem to believe I may have access to an institutional equipment budget due to the materials science reading I do and the physics videos I watch.
From time to time I reinforce their erroneous assumptions by doing price comparisons for gas spectrum analyzers and laboratory safety equipment that might be handy around the house.

⚛️ What is ITER actually trying to achieve?
It is not a power plant. It is a research machine, designed to demonstrate that fusion energy is feasible at scale: 500 megawatts of fusion power from 50 megawatts of input, a tenfold energy return, sustained and controlled for the first time ever.👉 https://buff.ly/3C6xMoZ

⚛️ What does it actually take to make fusion energy work?
Temperatures above 150 million degrees Celsius. Sufficient plasma density. Long enough confinement time. All simultaneously. ITER uses a tokamak and powerful magnetic fields to achieve exactly that.
A fusion reaction releases nearly four million times more energy than burning fossil fuels.

💁🏻♀️ TIL: 🧵🌐 The hairy ball #theorem says you can’t comb a #sphere smooth without a cowlick somewhere.
The same rule explains why #Earth always has a #cyclone spinning, why #fusion reactors use #doughnut shapes, and why omnidirectional antennas can’t exist. #Wind patterns over the #Arctic and #Antarctic circles illustrate the proof.

Llegan a Cadarache las últimas piezas del solenoide central de ITER, el corazón que encenderá y sostendrá el plasma a 150 millones °C. https://aidoo.news/noticia/W40ZRM

@DerLogiker Mehr Energie als man aufgewendet hat im physikalischen Sinn bezogen auf das Plasma, nicht im Ingenieursinn bezogen auf die gesamte Anlage, vermute ich.

In a quiet corner of southern France, an international mega-project is forging ahead with its mission to demonstrate industrial-scale nuclear fusion. We got to take a look.

Der #Tokamak bekommt einen zweiten "Auspuff" verpasst! Mit einem zusätzlichen X-Punkt im Magnetfeld lässt sich die Fusionshitze nun endlich bändigen. Sozusagen Plasmatuning für bessere Abgaswerte - nur dass das Abgas hier 100 Millionen Grad heiß ist. https://winfuture.de/news,151310.html?utm_source=Mastodon&utm_medium=ManualStatus&utm_campaign=SocialMedia

It may not be in my lifetime, but with the progress they’re making I’m sure they’ll figure this out.
