Nuclear fusion cancelled?! Is this this the end for ITER?
New science and technology videos every week! We show innovations that make our world better and point the way to our future. The videos are made in Germany, but the topics are from all over the world.
in the 1920s, scientists recognized the energy potential that lies behind nuclear fusion. One gram of fuel in a nuclear fusion reactor is said to produce as much energy as eleven tons of coal. For this reason, every effort is being made to make nuclear fusion possible in Germany in order to generate energy. And after some promising news from the field of nuclear fusion recently there are now rather dramatic headlines predicting the end of the largest nuclear fusion project. Today we'll find ...

A start-up from Austria has designed a helicopter that flies with ‘rolls’ instead of rotors. The designs look like complete science fiction at first, but as you can see here, there is already a real prototype that shows that the technology works. Let's find out how the whole thing works physically, what the advantages are compared to other electric flight concepts and what hurdles there still a...

The dimensions of this aircraft, to me, is its biggest selling point. Sure, it's larger than a normal vehicle - but not insanely so. The lack of wings is a good point though: what happens if power fails? The best answer is a parachute, á là the Cirrus light aircraft.
The term is “angle of incidence” or “angle of attack”, not “angle of inclination”. It is the angle of the chord line relative to the oncoming “wind”, not relative to the horizontal.
Also, “albeit” is not a German word so it is not pronounced “all bite”. It is a word constructed from the phrase “although be it (that)” way back in Middle English. The V2 construction is odd to Modern English, but it is a set construction. So, say “al-be-it” with the emphasis on the “be”.
ITER needs to be re-evaluated. Its primary purpose of exploring how to make an industrial fusion plant has clearly failed and is dead. So what science can ITER do that cannot be done by cheaply and quickly upgrading other facilities?
Nice video. ITER is a doomed project, the so-called flagship of nuclear fusion research is sinking before launching! - the start of ITER experimental campaign is a couple of decades late (and counting....further delays are rather likely) - the actual D-T experiments will start even later, probably not before 2040/2045 - ITER is massively over budget... it should have cost less than 10 billion dollars, it will cost... well, nobody really knows, but 50-100 billions could be an educated guess - a serious technical issue may arise, not unlikely due to the extreme complexity and first of a kind nature of many of the ITER components (for instance a fault in one of the coils may jeopardize the whole project) - even if everything works, it is now clear that ITER will not provide all the results and technical inputs for the next machine that it was supposed to give... In fact, ITER is a very badly conceived project, badly designed and even worse managed. A very large fraction of the budget dedicated to the development of fusion worldwide is going to the construction and operation of a single machine which should have been the only step needed before DEMO. In Europe, contributing 45% of the ITER construction budget, little resources are left for other projects. The other six ITER Parties contribute only with 9% each, so they may reap all the ITER benefts (if there will be any, that is) with little investments. With ITERm , decades and tens of billion dollars will be simply wasted (putting all your eggs in one basket). Now, additional billions are necessary to fix some technical issues. For the good of fusion, it would be better to revise deeply the whole nuclear fusion development strategy (especially in Europe) and ditch ITER (I know, billions have already been spent, but that is not a good reason to waste many more billions.). Smaller machines, more manageable, dedicated to the development of the many technological and scientific aspects which are necessary for the development of Fusion, that will not be tackled by ITER and that are still far from being solved.
Lol seit wann auf Englisch?
ist sein englisch Kanal. Man will ja irgendwann auch mehr Reichweite nehme ich an
I'm curious to see how AI will affect development.
Me too. It has already changed some designs, especially the way you can arrange magnetic fields.
Loved being a part in this! Amazing explanation and video 🚀
Hi all, Sorry if I may sound harsh but I have to clearify some things here: First of all for the German audience: there had been a recent video from Norio which represents the current situation more correctly which was actually done in collaboration with the Max Planck Institute for plasma physics (hence fact-checked by scientists). ITER is by no means „useless“ or „not worth following“ anymore. Disclaimer: I will not be talking about the whole start-up thing here (besides CFS who is following with SPARC/ARC the tokamak line). Whether the stellerator or tokamak concept will be the first power plant concept does not matter for ITER: Goal of ITER is - besides proving that it does work and enabling research & sharing knowledge - is to test the breeding blankets necessary for all D+T designs (tokamak, stellerator, laser/inertial-fusion). Without a design for these blankets there will be no power plant - fullstop. And there is no chance any running power plant is faster than ITER at the point of testing these :D So the goal still is valid and important! Please do not get me wrong here Jakob - I usually like your videos :D (I don‘t want to be misunderstood at this point as simply being rude or anything) but it would increase the level of factfulness if you‘d actually speak to the well established institution (like the MPI as press releases sadly are not representing everything correctly … sadly :/) They are very responsive in fact if you refer to their „Öffentlichkeitsarbeit“ :D
First of all, thanks for the comment. Actually, in the video I don't say that it's not worth following Iter, I just explain that there is a discussion about it - not my own opinion, but a discussion in the scientific community. As I say at the end of the video, I don't have a definitive opinion. No matter what, research is still needed in this area, as you said. Actually, I have talked about fusion energy several times with people working on ITER and especially with one of the researchers from Jülich who is working on plasma-material interaction and surface processes in fusion devices. ITER has already produced great results for fusion energy that can be used in subsequent projects. I think this is a fact that is less mentioned (maybe also in my video). And of course they told me that they want to continue with their project. But they also said that ITER is very complicated because of all the different players, as I mentioned in the video. So again, not my opinion, but the idea of this video is to show that there is a discussion going on and of course, as always, you have to bear in mind that each side has its own interests and depending on who you ask you will get different answers.
Can you arrange them by their average distance?
Good idea, I try to create it next week
Plotting their distance distribution would probably help understand the results
You should have asked which planet is most of the time our closest planet? From the distances of the orbits, Venus is the closest, or all books have to be rewritten.
Can you guess by the accent where this guy is coming from 😁😁😁
Hey guys, first of all thanks for all the comments. I understand that the music is too loud and we will change that in the future. First of all, sorry about the technical problem. It seems that we didn't hear it through the speakers of our editing computer. But in the next episode it will be fixed 👌 Also I spent last week in New York and did some interviews. So the first exclusive video at the German Science Guy will drop soon 🔥It will be about nuclear energy and how people from outside Germany think about Germany stopping nuclear energy. What are the aspects that you would like to be included in the video?
Something about the economic perspective. N. energy only works, because of governmental funding. Is it a good idea, to rely on something so expensive? And where does the Uran come from? There were no Import sanctions on Uran from Russia, just saying. That's what I call dependance
Very interesting topic! Looking forward to the new video! I would like to know how other countries managing the nuclear waste. If they actually have efficient and ethical ways to deal with it? Or maybe there is simply no awareness of the issue?..
…sein englisch is völlig ok und wird bestimmt noch besser…zumal es sich auch noch um fachlichen Stoff handelt…Musik kann einen tick leiser. Weiter so🙌🏼🙌🏼🙌🏼
please don't call Europe a country. most americans already have trouble enough with their world view to get this poured ontop of it
Bitte mach die Musik leiser, die Geschwindigkeit etwas langsamer und vor allem: den Akzent weniger stark.
Musik kriege ich hin, Geschwindigkeit muss ich schauen und das mit dem Akzent wird schwer :D
@@GermanScienceGuy-z8e Ein Englischlehrer in Neuseeland hat mir beigebracht beim th meine Zunge unter meine Schneidezähne zu legen. Dadurch wird das "se" auch tatsächlich zum "the". Probiere es mal aus, zuerst fühlt sich das sehr clunky an und man brauch ein bisschen bis die Muscle Memory einsetzt. Aber wenn es erstmal klappt gleicht es schon deutlich den deutschen Akzent aus. thirty-three thirty-three thirty-three,... ;)
@@GermanScienceGuy-z8e Die dentalen Frikative üben und im Hinterkopf behalten, dass Englsich gefühlt nie so ausgesprochen wird, wie es geschrieben steht und dann wird das schon.
ich fande den hintergrundmusik auch etwas zu laut
Okay, ist angekommen, das ändern wir in Zukunft
Blöd nur das Amerikaner das metrische System nicht verstehen xD ich empfehle bei allen Einheiten den Wert auch im imperialen System anzugeben bzw. einzublenden, ebenso mit Währungen USD ist international besser verstanden ;)
Versucht ihr mit der lauten Musik die schlechte Aussprache zu verschleiern? Leute wie kann man so viel Arbeit in ein Video stecken und dann bei so einer Kleinigkeit 16 Stunden später immernoch nix verändert haben? Das Problem merkt man doch schon 4 Sekunden nach Anfang des Videos, hört das keiner Probe?
Wünsche dennoch viel Erfolg. Ob man eine Synchronstimme braucht weiß ich nicht und ist schwer zu bewerten.
Ich kann kein englisch. Aber sieht cool aus 👍 (Doch verstehe englisch, schon gut). Aber das "Los gehts" find dich super ALGORITHMUUUS
Cool :)
Great. Viel Erfolg :)
Unterstüzung aus der Heimat is wichtig!
Subscribed 👍
Thank you!
Your German accent is fine, considering it could also be bavarian or sächsisch 😂
:D
Wenn ich als Deutscher Deinen deutschen Akzent extrem ulkig finde, dann ... ist es anscheinend genau richtig.
I'm just here for support, great video!
"This is because no material could withstand such high temperatures." - I have to disagree. While the particles have a very high temperature, since there are so few of them, the actual energy in form of heat is relatively small. It would be like a very fast bullet hitting a very dense material. The kinetic energy would get absorbed completely by the sheer difference in mass without having any noticable effect. That is one of the reasons why nuclear fusion is very safe.
high temperatures are indeed an issue. There are parts of ITER which see a thermal load of 10-20 MW/sqm and that's a lot, as any thermomechanical engineer may confirm. Additionally, materials will be subjected to highly energetic neutron fluxes (well, if evenually they manage to get a reasonable amount of nuclear fusion reactions....). Those neutrons will damage components which will need either frequent replacements (not really compatible with a commercial plant, and producing radioactive waste) or new materials will need to be developed (some research is on-going but, since all the money is dumped in IITER, there is little left ).
stabile deutsche aussprache. behalte dir das bei ❤
Hey, tolles Video, aber wie auch schon andere gesagt haben, die Musik ist ein wenig zu laut. Zudem könntest du noch ein wenig langsamer reden. Am Anfang war das auffällig, später war das dann besser! Auch die Menge an Informationen pro Sekunde, war am Anfang ein wenig zu viel für mich. So könnte es anstrengend sein zuzuhören. Ansonsten finde ich's super, weiter so!
They are called pencils
Für den Algorithmus
The music should be mor silent, it somehow hurts in the ear, especially if you need a loud noise to understand everything. If you are not a nativ English speaker. But still very good Video.
Let's make some internationals Sciencelovers.🫡
Good video, but the music is too loud in relation to the speech.
Thats eighr, you hardly understand him speak - He also speaks a bit unclear
For algo😂
algorithmus 👍🏽
music too loud and maybe yet too technical for a non native speaker. weniger genuschel und n bissl kohärenter sollte das ganze auch sein. no offense. kinderschuhe. und jetzt ab dafür ;-)
ALGORITHMUS
Nice that you added subtitles :D
Important tip: Add subtitles like on Insta or Tik Tok. This makes a big difference to how much you understand of the video, especially if you're not so well educated in English or watch shorts without sound (which many people actually do). You can really hear that you're German.
I forget the exact math, but they've done one, two, three, and more bladed rotors on those horizontal axis wind turbines, and three blades apparently hits the sweet spot for mass, size, and cost vs power generated per acre of land. The real interesting thing is how they've nearly built it on a vertical axis, and their "single blade" doesn't have a variable geometry.
I wouldn't want one
Yep. These buildings are just trophies while there are homeless people in the street
Toni Kroos is that you😅
Technik des Mittelalters !
Englisch??
Sachen gibts 😊
💚 Thank you for your efforts. I really appreciate it. You are great!
Diese Kommentarsektion ist nun Eigentum der BRD!
da ich glaube, dass auf diesem Kanal ein Kommentar noch etwas mehr wahrgenommen wird, hier ein Wunsch für ein Videothema. Es wird viel über neue Innovationen und Forschung berichtet und ich finde es könnte etwas mehr zur aktuellen Entwicklung gesagt werden. Konkret würde ich die Elektifizierung des LKW-Verkehrs vorschlagen. Ich bin auf den Kanal eines Truckers (Elektrotrucker) gestoßen, der elektrische LKWs fährt und das ganze sogar schon jetzt als deutlich vorteilhafter, als Diesel-LKWs empfindet. Das zeigt mir, dass wir in dem Thema schon deutlich weiter sind, als gedacht und dass es möglich ist, die Wende zu schaffen, wenn Firmen, die tatsächlich die Vorteile gegeneinander abwiegen die Entscheidungen treffen, und nicht irgendwelche Gewohnheitstiere, die ihrem Motorengeräusch nachtrauern.
Der Name vom Channel ist irgendwie billig und wird deinen Videos nicht gerecht. Trotzdem viel Erfolg und weiter so!
