But if you had tied your career to it, you would have a job in the same area for centuries.

I was involved in the building of the UW-Madison HSX Stellerator which predated the W-7 (and the W-7 used a lot of the information on how the HSX actually functioned as a basis for their design). Stellarators have huge advantages over a tokamaxs. I was told by the physicist that if a tokamax ever reaches steady state that it will melt as it's theoretically impossible to cool that shape faster than it would generate heat. As such it's not suitable for more than pulse power generation. A stellarator in theory can be cooled faster than it generates heat from fusion - and are thus suitable for steady power production in the future. I read an article in the last few weeks that there is also a fusion startup company in Wisconsin which is based on stellarators and has key people from the UW-Madison HSX stellarator program involved - including names I recognize from working with them on the construction of the HSX stellarator. I wish both stellarator startup companies the best...

@alexanderkohler6439

28 күн бұрын

"As such it's not suitable for more than pulse power generation." The reason for that is a different one though. Tokamaks do run in pulsed mode only by design. It is due to how the magnetic confinement of the plasma is achieved. Its main component is an induced current within the plasma (this current is, by the way, also responsible for heating the plasma). In order to induce this current, you need a primary external magnetic field which has to steadily increase. However, you cannot increase this primary external field indefinitely. After reaching a maximum, induction will stop as well, the confinement and the fusion of the plasma will break down and thus conclude a full cycle. After that you have to start over again with a new cycle.

One problem is the scaling laws -- which (I think) signifies that these gizmos are anticipated to work better at larger sizes, which also means giant projects with giant budgets. This has arguably led to a bit of comedy -- the current NiF (laser shot at a tiny target) National Ignition Facility is the successor to a series of increasingly bigger and bigger machines. This time it will really work! And NiF works better at fusion than Shiva and other earlier smaller laser machines, but still not remotely close to becoming a net energy source. SABINE: how about some videos about the scaling laws? Why is bigger not just bigger but expected to be disproportionately better?

@@MrToradragon Nice assertion, there. I love it when people just assert how things aren't going to work without doing even an order of magnitude calculation. Here is mine that it will: Put a 100 meter tower in your back yard. Have 10, 2 meter high, 1 meter in diameter lead cylinders that get lifted by a motor when there is some power from something: wind, solar, my rage for people who think just being negative makes them smart, and making me jump on an excercise bike, etc. Let's calculate the stored energy from this. Start with the volume: let's see, 10 of these things*pi*r^2*L, So we get roughly 16 m^3 of lead. Lead's density is about 11 g/cm^3 so we can do an easy conversion to 1e4 kg/m^3 for lead's density. Now then, we can just say that we have roughly g=9.91 m/s^2, lets round to 10 m/s^2. So how much force do we have hanging up there if we are only 100 meters off the ground? Roughly 1.6 e6 N or 1.6 MNewtons. We now can just calculate how much gravitational potential energy is stored there to be run with a pulley pulling a turbine to generate some 3 phase or whatever. With 100 meters to travel, it looks like 160 MJ. Let's compare that to one of my favorite power banks, that I love, that has roughly 1000 W-hrs of electrical energy in it. I hate W-hrs, it is a really ridiculous unit, when we have Joules, but anyway, lets convert it. It is almost like the power company doesn't want you to be able to quickly, clearly, compare energy scales or something. 3.6 MJ in one of these power banks. Hrmm, looks like we would need around 50 of these things wired up to match the energy in the gravity tower. We should start producing and storing electricity locally so we don't rely so much on distribution networks that can get knocked out by solar flares. Furthermore, dams have major environmental impacts on waterway wildlife and wetlands. We should try to find ways to live in harmony with the rest of nature, you know, using our imagination, creativity, knowledge, etc. Instead of just asserting nonsense that we learned from someone who ultimately tied back to having some sort of profit motive to trick people into not looking beyond what they tell them. Good luck to us all, @MrToradragon. Enjoy your shame. You have certainly earned it. Also check my order of magnitude math. I have been known to make mistakes from time to time. It would be a good exercise for you. If you find that I am several orders of magnitude off in my comparison, I will give you a bright shiny gold star ;) Oh and if you think that the tower is a hazard, make more of them that are shorter than 300 ft high. Also, we have pretty good tensile strength alloys these days on suspension bridges, etc, we could even make carbon fiber stuff. We can encapsulate the lead to make sure it isn't a hazard, and put stabilization locks on the weights with padding around them if there is a hurricane or whatever. Use your imagination.

4:43 Non-Isoformic Non-Symmetrical Field-Application Dynamic-Stream-Stellerator. ( I dub thee "NINS-FADS" stellerator) One way to decrease particle bouncing is to use non symmetrical positioned fields, possibly in combination with field attenuation and periodicity. That would mean that there's no fixed positions for the particles to entrap in, but also the variation in field strength and the duration of the fields dissallow such entrapments. Oscillating the fields at a high frequency makes the time during interaction change for each particle, and thus the outcome of the interaction and with that the vector. The fields also being variable in strength, slightly, does the same, but in a different way yet again from the oscillation. Compounding these two ways in which deliberate non symmetrical interaction is achieved lowers the entrapment to a chance of nearing zero. With the lowered entrapment the chance of damage to the machine is also lowered. Personally, I don't think fusion will ever become a true power gain, since the production of the fuel also costs money as well as the maintainance (replacement component parts), but still this may help.

I like very much that you emphasize it's more complicated- but that is good. It's right because the Universe is not simple- it's complicated.

Do a whole “episode” on lithium, someday, please. It seems a highly useful element for energy production: boosting atomic weapons, mixing with fusion plasma and increasing density, use as working fluid in batteries, a salt, a medicine. What the heck!

Thank you!

The fact that this channel has 1 M subs kinds of reassures me 🙌

I doubt if electricity from fusion will be cheap. The fuel may be cheap but the installation is very complicated thus expensive. The sun shines for free, but that doesn't make solar energy automatically cheap. Same for fusion.

As an Argentinian I really like your german accent. It reminds me of granpa. All jokes aside, I wish we invested way more into fusion. We have had continuous achievements in the last decades and could be a game changer in the climate change fight if we accelerate the progress. It will take decades but would give us an upper hand down the road

Sabina has figured out why I can't get enough of her videos! (It's when she says "Einstein" -- yes, that guy).

Thanks for the post. Maybe you could explain why stellarators need that mobius-inspired shape to achieve better stability than tokamaks and how the various fusion projects around the world are doing?

I am a great fan of your channel. Would love to hear a video on the problem of waste heat if we get "endless cheap energy".

I would LOVE to write a particle article.

Dunno if it's me, but her delivery seems more energetic, upbeat, engaging, whatever, lately. Very fun to listen and watch.

I've heard someone say once that the Stellarator design should have worked, and has briefly worked in "stutters" in the past but that its initial conception was too unstable in operation. I don't know how true that is but I think it's interesting that the concept is being revisited with improved components and a revised design.

4:56 Maybe the real fusion was the friends we made along the way...

Proxima Fusion, cool name

4500 years....you kill me!! LOL

"aproximately in the year 4500" You kill me with such jokes

It would be really cool if you could make a video going over why a stellerator's complicated fusion path is more efficient than a tokomak. One would think that adding all those twists and turns would make things less efficient, not more. I'm curious about the physics going on here.

I saw a few videos of you speaking German the whole video lol I can understand because my great grandmother didn't speak English. Sorry I am seeing this late. I hope they Have success at this new facilities being built.

You have the most English sounding German accent ever but it's awesome hehehe, thank you for your amazing content!

Stellarators are such awesomely exciting machines!

With a German accent like that, you should be able to pass the O level German exam I did in England.

I worked for a company that built a linear accelerator based on this fundamental principal. It was a prototype created for DoD call SLIA - Spiral Line Inductive Accelerator. This was in the early 90's...

~~because of my german accent~~ By far neither the only nor the most important incentive to chase after your clips - but a not so side-ish side-effect of that accent is the pleasure of hearing German names pronounced in 'Die einzig wahre Weise'™ aka ' the most minutely true way'.

"...by the time it'll finish construction, approximately in the year 4500" 🤣😂😁 I'm 76 and have been hearing about the promise of fusion since I was a child, so the "just around the corner" promise has long since gone stale. But recent positive news out of Korea, the UK, and the US has given me new hope of seeing commercial fusion in my lifetime. I certainly hope that the QUISST (QUasiISodynamicSTellerator) is a huge success!

"the year 4500" had me laughing for a whole minute. Years ago I made the joke that a half completed ITER would become the center art sculpture to a shopping mall in the future. I got a lot of hate for that.

4:15 Boozers at work! Work hard party harder. I wish this startup luck!

This company is good. I think you should cover ‘Type One Energy’ as well. Great startup!

8 minutes is amazing! I hope they have a way to get energy out of it though.

Fusion power is the world's most expensive pipe dream. Plasma = superheated Superconductor = supercooled Having these two right next to each other ALWAYS requires more energy than the fusion reaction provides and that will NEVER change, no matter how many optimistic press releases they put out.

Writing pessimistic claims in all caps doesn't make you right. Loud claims were also made that people will never fly in aircraft heavier than air, and similar sh*t. Read some history books my friend. And if you try to claim something about engineering then I'm afraid you'll also need to learn maths, and suffer through proving some actual theorems, and experience all kinds of surprising and counterintuitive results on the way.

This is wonderful news! I have been very excited about the potential of the Wendelstein stellarator project, and a startup looking to refine it even further is exactly the sort of thing that we need right now. And, as you say, all too often the great leaps in scientific progress occur not because someone has one utterly brilliant new perspective, but hecause of seemingly "small" and "unrelated" developments in some other field. If machine learning gets us a functional stellarator, I'll be quite a bit less critical of that whole branch of computer science, that's for sure!

1:07 Danke, Fräulein! 😅

Always thought trying to confine the plasma in a doughnut was daft! I am totally with this concept. Rather let the plasma do its thing and build around it!

Thanks Sabine, I was wondering if the elegant stellarator design was being developed.

Love that accent! (and that intelligence)

It’s all about energy gain. Assuming a system / technology is developed that achieves sustained fusion, the next step is to extract sufficient energy to enable a worthwhile gain. Current fusion systems require relatively large electrical supply to operate. So a total system energy gain must exceed unity by a significant margin to be of practical use.

Stellerators always sounded like the coolest idea. Using seawater as fuel? Sign me up!

Hey Sabine, thankyou for the video. Covering all this alternative energy research is fantastic. I’m wondering if you could do a video on how your audience can influence the trajectory of climate outcomes. We all know we have a “carbon footprint”, and the more people learn, the more we realise that reducing our individual impact isn’t enough, and distracts us from the politics of co2 emissions, but I don’t think anyone knows what to do with that information. I feel that most likely everyone wanting to learn more about these technologies probably has a burning desire, however small or large, to make some meaningful change with this climate crisis, but we don’t know where to place our efforts. Should we become climate influencers for better public awareness? Should we write to or phone our representatives in office? Should we have our unions strike? Protest in the streets? Organise local climate discussion meetups? Do we demand more of our politicians once we vote for the good ones? I know you’re mostly focused on the research side, but it feels as though communicating to individuals is only effective and valuable in the long run if we know what to do with that information.
