Wendelstein 7-X - from concept to reality

[@SUBboy]

Plasma at 100,000,000° C, and it's just 30cm from magnets at -270°C. I know that isn't something new, but damn that is just brutal.

[@dennisgarber]

Sounds like the way I cook.

[@MarcelKlein88]

What a masterpiece of engineering! I hope the machine runs as expected, I can't wait for your first results!

[@mrmathews4900]

It's looking good so far :) www.nature.com/articles/ncomms13493

[@leocorral]

It was able to contain the plasma for the time they needed but it was just a proof of concept

[@michaelkasili]

Thanks Professor...lol

[@beto4655]

Viewing this takes me back almost 40 years when I left the Wendelstein project, then located at the original IPP north of Munich. For me, very exciting to see that the project is still alive. Congratulations to all my colleagues from those days and to the continuing team.

[@rxch6057]

and... IT FUCKING WORKED!

[@ThePostApocalypticInventor]

Bravo! This is a great explanation of the basic components involved in this marvelous project! I wish I could visit the Torus-Hall in real life ! Too bad that only such a small number of people watched this video until now. I wish you guys good luck with the project !

[@TilmanBaumann]

Since you speak German. Listen to episode 36 of the alternativlos podcast. They go into fascinating details. Especially about the ancillary support systems. Totally worth it.

[@hunty11]

Very nice video, particularly the section from around 3:30 showing how the machine is made up in a clear and logical order. I wish there were videos like this about other machines. Thanks.

[@Cuix]

This is some straight-up impossible sci-fi babble. Incredible and beautiful work.

[@sidviscous5959]

+Jarmahent 200 years later: "Arouk zugzug alunda Lana."

[@MetallF]

+Jarmahent more like 50 years, or less. We are the generation that witnessed the rise and "fall" of so much tech like the floppy and cd, just to name a couple. Let's just hope that the degenerate ideologies of political and religious men doesn't destroy this.

[@dibbidydoo4318]

+MetallF in 50 years it still cost hundreds of thousands of dollars compared to today's billions of dollars.

[@nicol1146]

+MetallF Yeah like we've done with nuclear power. Thanks to technology, now my nuclear powered smartphone never runs out of energy. And my car with the tiny nuclear power plant works great as always.

[@jmitterii2]

+MetallF Or the ignorance of the masses on how such things work. So many don't understand chemistry let alone nuclear chemistry. "Chemicals are bad, and radiation will turn me into a squid."

[@nomad3239]

This thing must have been an absolute nightmare to 3D model and design.

[@carlosdgutierrez6570]

Alex Rutherford just imagine what kind of nightmare must have been built the actual machine

[@johnsteel5347]

Luckily the magnetic coils were designed using a supercomputer

[@danthemancasey]

Where you see a nightmare I see a wet-dream!

[@Sancarn]

This is the best way to explain engineering. I wish museums did this kind of thing with stuff. Like a piece by piece reconstruction of an object and explaining each part in detail, why it's needed etc.

[@murch2]

Against several reasons that sometimes humans make me shame, this cientists make me proud to be one human. Great video and .. Amazing machine.

[@DaveTerrasidio]

Excellent. Also, I love how it looks like something from 'Akira'. :)

[@danfechter2923]

I congratulate everyone involved with this project. I hope it works as hoped! Even if it does not, this kind of experimentation helps advance our understanding of the science, and another forward step is made.

[@TheJaredtheJaredlong]

There's engineering, and then there's German engineering.

[@TTuoTT]

There's also Japanese, Italian and American engineering. Chinese coming soon.

[@TilmanBaumann]

Of course it's a very international project. But thaks for the flattery.

[@yallowrosa]

somewhat twisted indeed, will it work?

[@360AgencyBerlin]

So Powerful! Mind blowing to see that such an advanced technology can look like so organic!

[@jjjddd2937]

so many questions !!! this is truly a feat for engineering, physics, humanity.media outlets said it may be turned on this month. good luck.

[@OlivierSuire]

Very clear and informative. Thank you so much !

[@GrainBrain]

Extremely complicated and extremely necessary thing.

[@johnnythreefour2902]

what a crazy looking machine. Amazing engineering.

[@wihlke]

This animation helped me complete my stellerator! Now when the output ratio has finally surpassed 1.0 so I can power my gaming rig :) Thanks

[@DudeonetoNothin]

Needs more cowbell!

[@free_spirit1]

Anyone who is knowledgeable enough, please let me know: Which component supports the vacuum? The inner jacket (red at 5:40) or the cryostat (brownish red, 7:16)? How were the panels of the internal jacket made (red at 5:40)? Is each individual panel stamped and then welded? Are both the cryostat and the inner chamber kept at a vacuum or is it only the inner chamber? Also, what determines the minimum size of the stellarator? Does it have to be this large or can it also be made smaller?

[@abudabi2222]

This is what makes life a whole lot better everyday. that's what i know.

[@mikegLXIVMM]

Fusion power has been "Just around the corner" for many years. I hope this works.

[@michaelneil3449]

Who do I need to talk with to buy 1 of these Wendelstein 7-X

[@ddorman365]

Exactly!!

[@bananlaksen]

wtf is up with the background music? How do you even find shit like that?

[@afelipe2001]

extremely detailed and explained clearly and in a simple manner. awesome video.

[@sharinganproz]

so how do they capture the electricity?

[@plasmaphysik]

+クリス Wendelstein 7-X is a research device, it will not produce energy. A future fusion power plant: www.ipp.mpg.de/14743/kraftwerk

[@AdamNair]

+Max-Planck-Institut für Plasmaphysik ITER's test power plant uses a Tokamak right? Would the next step in this Wendelstein 7-X research be the creation of a Stellarator based power plant?

[@TJGalloway1]

+クリス Neither fusion or fission reactors 'capture electricity.' They're used to heat up water into steam which drives turbines to generate electricity.

[@hjembrentkent6181]

+Max-Planck-Institut für Plasmaphysik How would you capture the energy? Thermocouples?

[@OyVeey]

+Max-Planck-Institut für Plasmaphysik That means it'll take a lot of energy to test its confinement ability then, if it's not feeding energy back into the process?

[@bubbletanking]

The narrator and the video itself keep giving me a Prokhor Zakharov vibe from Alpha Centauri. Or otherwise, simply a vibe of the datalinks therein. It's great.

[@AndrewLomenzo]

creepy music in the video makes this thing look like a doomsday machine.

[@slashiesmokesweed]

I know, right? The video is fantastic, but the background music is freaking me out.

[@jaikee9477]

+Andrew Lomenzo J.S.Bach, one of the top 3 greatest composers of all time, is "creepy music" to you? Wow.

[@AndrewLomenzo]

Jan Aike I didn't realize Bach composed his music on MIDI synths.. my mistake..

[@jerryeberts]

Only his later music.

[@WiseManOncePosted]

And to think, for all of the staggering technology, time and understanding of thermodynamics/particle physics required to construct such a revolutionary object, it still pales in comparison to the human brain in terms of complexity.

[@orionti6215]

and the same complex brain is so simpleton in many cases :D

[@hectorsantos4662]

the most complicated donut on the history of mankind

[@TTuoTT]

We call it a Tokamak. And the Upgrade to the basic system of a "donut shaped magnetic field" designed for holding a plasma stream is called Stelerator

[@TheRealPlato]

Thanks for the explanation, good luck containing hot plasma!

[@megatwingo]

The first test to generate plasma was successful now. It seems to work.

[@GDplusEng]

interesting video, but what you don't explain is how you "harvest" the heat for energy production?

[@plasmaphysik]

+GDplusEng Wendelstein will not produce energy. A future power plant: www.ipp.mpg.de/14743/kraftwerk

[@jjfake9042]

+Max-Planck-Institut für Plasmaphysik ITER is just a bigger tokamak.

[@Biltospill]

you are concerned about the easiest process in this very complicated process??. They will find that this design will not be able to contain and leakage will be an issue which will cause random cooling. I believe the answer lies in studying the sun and learning how the sun keeps its shape, only then will you be able to contain plasma.. this donut shape will prove to be too complicated and using a rotating field and the shape of a ball or globe will prove to be the ultimate solution.

[@SUBboy]

Goddamn that coil system is one of the prettiest inventions I've seen in a while!

[@theultimatereductionist7592]

Forget the International Space Station or CERN. THIS is the most complicated expensive & amazing machine built by humans!

[@TerryB751]

What about safety concerns in the event of failure in parts of the system? Time has taught lessons regarding catastrophes in fission reactors throughout the world.

[@plasmaphysik]

see www.ipp.mpg.de/14767/sicherheit

[@felixnagl5962]

'Thus the technical realisation of a large optimised stellarator is far more complex than one would have expected given the apparent simplicity of the original idea.' Sure, because everyone thought this is simple.

[@Orangino4u]

A beautiful project !! Keep up the good work !!

[@bl4ck1c32k8]

Amazing engineering work!

[@not_the_pasta]

Right now this thing is huge, but there will be time, when we will bring one like this along on our road trip like we do with our laptops and cellphones now.

[@bennysh]

I think this machine can be smaller now with the new kind of superconductors. amazing engineering nonetheless.. thanks for the clear view of how this thing is built.

[@TabulaRasa001]

Fusion reactors regardless of design will always be more efficient the larger the design. Not as relevant for a research reactor but certainly for a production power station.

[@matthuckabey007]

Outstanding.

[@YouNeedToHearThis]

Great video, but my goodness is that background music annoying. Almost impossible to listen to with headphones on.

[@FirstNameLastName-okayyoutube]

This is great work =) Not to full of buzz words nor over focus on technical aspects. I would love to see some historical modeling on how the puncture points were worked out. So many videos out there say "quantum mechanics" in both an attempt to impress as well as divert attention =( Obviously here we are dealing with energy levels mixed with I guess it may be called steric strain, but a common language description like this video would go a long way in demonstrating confidence in future experimentation!

[@Guds777]

But if or when fusion reactor is possible, won't it just work similar like a transformer, primary and secondary coils, plasma in primary and output power in secondary. And some hybrid metal/graphite/nanographene core in between

[@stephenangus7296]

The Plans and documentations would be amazing. The sensors would be of great interest to the large spacecraft industry yet future.

[@highwaltage]

im just an idiot. but why are all reactors donut shaped? if we are to mimic he sun. should we not have a central focal point for the plasma in a sphere? counter rotating fields using coils like in a rodin wind?

[@Fummy007]

Anyone know the music at the start? I think its Bach but can't find it anywhere.

[@randallpcrittenden]

Bach's Well Tempered Clavier Prelude and Fugue No. 1 in C major BWV 846

[@finnheinemann3682]

Could you reveal a 3d model of this for my physics referate please?

[@filipebarbieri6367]

Hello there. I am currently graduate in Business but I plan to go for science and energy...Which graduation course should I take in order to be part of the fusion energy development, as well as other energy sources? I am 23 years old from Brazil, thanks in advance.

[@rcguy96]

+Filipe Barbieri UC Berkeley has a great Nuclear Engineering program that you could check out.

[@TJGalloway1]

Hi Fillipe! You should either get involved in physics or electrical engineering.

[@filipebarbieri6367]

thank you guys! I am looking something like that!

[@essellar]

+Filipe Barbieri The big problems to solve at the moment are mostly in the area of computational fluid dynamics. That's reflected here in the shape of the torus, but it also applies to the design of turbines -- it doesn't matter whether those are gas/steam turbines for conventional thermal generators (no matter what the heat source may be), water turbines for tidal generators, or wind turbines. It's a four-pronged problem -- physical, mathematical, computational and engineering (you have to be able to build the things you design, and they have to last) -- so there are at least four avenues of approach, all with cross-disciplinary interactions. And don't forget that there's still a lot of room for advancement in delivery and storage systems: batteries are horrible, and we waste a huge amount of what we produce heating up wires.

[@ddorman365]

Thank you Colleagues, well done, I'm sure you will be greatly surprised with the experiment outcomes, good luck, your friend and colleague, peace and love, Doug:).PS Beautiful job Max Plank Ins., Aveterzang!!

[@GNU_Linux_for_good]

Wow! What an amazing video.

[@Duraltia]

Soo... How do you ACTUALLY get energy OUT of this? Would one just run a set of heat exchangers near the plasma and from then on it acts like an ordinary steam engine on steroids?

[@Antares_451]

Imagine what other project they have been working on ;)

[@interstellar799]

Great animation and explanation

[@littleben619]

whats it do once it it is running?

[@richardhead8264]

Practical application?

[@coladict]

I think I'm missing the part where this thing makes electricity... Would have been nice to include that in the video.

[@D0d0Dada]

+coladict thats the secret part about it :D

[@Hortifox_the_gardener]

This thing isn't targeted to "make" electricity. It will rather consume electrical energy from the grid to be operated. This is about learning how to control such a reaction, how to sustain it and how to properly use it for energy production (I hate this incorrect term by the way). A real power plant would have to be larger and would also require ways to extract the heat (and probably various kinds of radiation for greater yield) from the reaction but it wouldn't need all this complex monitoring and scientific equipment. But this lies far ahead.

[@calvinsylveste8474]

What would ReBCO tapes bring to the stellarator table?

[@Ni999]

Dukky Drake Same thing they're going to bring to tokamaks. Much higher efficiency, less bulk and lower cost. kzbin.info/www/bejne/gZzTonRurqxsipY

[@PyrrhoVonHyperborea]

what would happen, when the magnetic "cage" would stop working from one moment to the next, while the plasma is on max temperature?

[@dirkdriessen1133]

it cools down rapidly

[@tremendous9703]

congratulation on the successful test. for how long do you expect the fusion to operate continuously ? what objectives do you need to research with the w7x and why does it take 50 years for a economically useful power reactor? what is the difference between the w7x and the LHD in japan, i mean why is the w7x so hyped in media ? arent all types of tokamak reactors, like ITER, now obsolete ? 'gluckwunsch' and i hope you guys can free us from oil-drama as fast as possible !

[@StreamPunks]

Is it on yet?

[@rafaelsuarez8250]

[@eloirossellivilardell9603]

Is someone trying to light a gas stove in the background?

[@MahmudulMithun]

ok google! how to use and where to use and why to use this Wendelstein 7-X ?

[@theultimatereductionist7592]

Boss: "You gotta heat it up inside to 150 Million K" Engineers: "You gotta be kidding me. Well, ok. But it's gonna get pretty darned hot on the outside." Boss: "And you gotta keep the coils on the outside near absolute zero." Engineers: "WHAT ... THE ... FUU##&&#*** ??!!"

[@suhasbharadwaj5457]

great going guys !!!

[@jerichom11x]

So how is it possible to hold plasma at such a high temperature without the machine itself vaporizing?

[@edge929]

+jerichom11x Did you miss the part about magnetic coils? The plasma will be suspended in the vacuum by magnetic fields and the coils themselves will be super-cooled to -270C.

[@Hortifox_the_gardener]

That is why these ridiculously complex magnets are there. The whole deal about this reactor concept is the sophisticated geometry of the magnets that keep the plasma in place. The design is so complex that it took somewhat advanced modern (microprocessor CMOS based design I mean) super computers to calculate.

[@tewlyx]

is this built under ground

[@tewlyx]

***** So is this machine safe when it malfunction -*-

[@Monkeyb00y]

Does anyone else find the "music" a distraction?

[@tomismerc6580]

eine unglaubliche maschine, hoffentlich wird sie funktionieren...

[@vonsteuben6475]

+Tomi Šmerc Sie funktioniert! ;)

[@tomismerc6580]

hab ich gesehen, aber muss länger funktionieren, 20 oder 30 minuten würde mehr energie rauswerfen als verbrauchen ob ich richtig bin? :)

[@vonsteuben6475]

Bedenke das Wendelstein 7X ist ein Versuchsreaktor. Da geht es nicht um das Thema mehr Energie produzieren als rein stecken. Sie hesten die Neuartige Technik und das Händeln des Plasmas. Bedenke das regelmäßig Treibstoff hinzugefügt werden muss und jede Temperatur Schwankung kann die stabilität des Plasmas einschränken und es kommt zum zusammenfall.

[@tomismerc6580]

ja richtig, das weiss ich, hab viel davon gelesen, sind alle auf der Welt nur Versuchsreaktoren aber Mann muss auch darauf denken, jemand muss die Grenze brechen und hoffentlich erschaft es Wandelstein einmal in der Zukunft. Die Japaner sind auch nahr, die hatten Plasma fur 100 Sekunden behalten aber mit nur halbes Temperatur.Der Kampf ist hart :)

[@vonsteuben6475]

dann warte auf den französischen Reaktor. Die wollen die effizienz testen. Jeder testet einen bestimmten bereich...
