Meanwhile my uni is debating on which meal are we gonna eat next week.
+dan iel cant go wrong with pizza
We chose chimichangas, which is, in some way, a source of limitless and relatively clean energy.
+dan iel mine is bragging because they got recognize as one of the 200 best universities in europe! And my countriy isn't an eastern country.

What of the methane releases? It seems you are setting your constraints as a closed system. How very economist of you.
@@skeetorkiftwon
If that was some sort of joke, it was difficult to tell
If you are serious, take it easy dude
Either way, that was weird
Amazing breakthrough. In my PhD thesis 30 years ago I crudely modeled this turbulence in the form of "filaments" that interfered with the transmission of IR beams used to measure plasma temperature.
Now, if we could do something about morons who troll serious UA-cam videos, that would be a real accomplishment.
+DJ Arnoldo The problem would solve itself if people didn't react to the trolls. When no one replies to them anymore, they will stop and start crying in a corner ;)
+DJ Arnoldo < Hopefully you now work at the Nat Ign Ctr :---)
Perhaps using said morons as reactor fuel.
I love trolls, what's wrong with some nice trolls? They use infrared beams to measure plasma temperature? Wow that reactor would make a hell of a remote control.
I just want to say thank you to everyone working in the field of fusion research. It genuinely is the most important area of knowledge our species can pursue at this time. While there are many other things we need to know and understand, everything we depend on comes down to energy, and a working fusion power plant design would go a long way to ensuring a peaceful, plentiful future for us all.
Very well explained. Straight to the point. Thanks!
Simple yet brilliantly nice, thank you.
Excellent movie
I have only a basic understanding of chemistry but from what I gather from this video is that turbulence within the plasma prevents or disrupts the fusing of the Hydrogen isotopes (hope I said that correctly) and now MIT has figured out, via computers, is that there are two types of turbulence within the plasma. I guess the question still remains, how to control this turbulence. However having a better understanding of the turbulence will get us closer to fusion energy.
Thanks MIT!
I want my Mr.Fusion on my 94' Miata soon please and thank you.
+Massachusetts Institute of Technology (MIT) < This may be dumb, but does 2 hydrogen have anything to do with 2 disturbances? Thanks. :---)
Exquisite movie
awesome
How do you convert mass into energy?
+Taseen Khan When you break it all down they are interchangeable. "Mass" is equal to the resting potential energy in an object and, as quantum mechanics states, if you increase speed you increase mass equal to the change in potential energy. All mass really is, is a lot of energy put into a small space.
+Taseen Khan To add to what Roboterson said, Einstein's relativistic mass-energy equation can be expanded to include momentum-energy equilibrium as well:
E^2 = (p x c)^2 + (mo x c^2)^2
where E is energy, p is momentum, mo is rest mass, and c is the speed of light.
Ignoring momentum changes and cancelling the squaring factor on both sides, you get the simplified equation we most commonly see today:
E^2 = 0 + (mo x c^2)^2
E = m x c^2
The energy-momentum relation is what governs your typical nuclear reactions, such as fission, fusion, and radioactive decay. Particle decay processes, such as neutron decay, utilize both parts of Einstein's equation, but such events only really occur in free-particle systems (free neutrons flying out of fission or fusion, for instance).
The rest mass doesn't change in most nuclear reactions simply because the number of discrete particles does not change in these reactions. HOWEVER! The actual mass DOES change in these reactions, by non-discrete quantities. You can observe this mass-difference phenomena when comparing isotopes of the same element, in which we routinely observe mass changes that do not appear to corroborate with the addition or subtraction of discrete masses as we would expect if we were adding or removing neutrons, which should all have the same mass. Instead, we find that things tend to get heavier the farther away we get from a stable isotope, when adding neutrons, and this is entirely due to the difference in nuclear momentum with addition of neutrons.
That difference in momentum actually makes the nuclei physically heavier when you weigh it. It is freaking weird that something with a different momentum has a different measurable mass, but that's just how the world works. This momentum effect only manifests in objects that move or spin at relativistic speeds, which excludes most every-day objects we encounter, which is why a rock will have practically the same mass whether it's on earth or on mars. But if you throw that rock at 10% the speed of light, it will gain enough relativistic mass to show a difference.
+Taseen Khan
Check out the youtube channel PBS spacetime. They have the best explanation without overly dumbing it down that I have seen.
The mass that is converted into energy in the case of fusion is not actually matter mass, but rather it is the binding energy that is released. To simplify, think of balls stuck together with glue, when the balls fall apart, the glue is released, it is the glue that is the "energy", but the balls still remain balls.
Good
I read somewhere we didn't find yet the material that could support the heat of the plasma. Is that issue already solved?
+Guillaume Combot They are currently using very powerful magnetic constriction to confine the plasma within the reactor so the walls of the reactor wont melt.Some estimate, we will have viable commercial fusion by as soon as 2030.
black star cool! (so, I wonder why they were talking about finding tougher materials to achieve that). It seems the community is waiting to see the results of the Wendelstein 7-x (apparently it started yesterday ! "Experiments with hydrogen plasma will continue until March") exiting time ! I hope I'll be still alive in 2030 to see that! spectrum.ieee.org/energywise/energy/nuclear/wendelstein-7x-really-starts-up
When I saw the thumbnail, I immediately started thinking about string theory lol
Great news! One more step to the thermonuclear fusion. It remains only get more He3, which costing extremely much...
+Arni Dexian Thermonucleair fusion (for commercial purposes) needs deuterium and tritium. Deuterium is easily gathered from water and tritium can be bred from a lithium blanket bombarded by fast neutrons from the fusion reaction. The two base components, deuterium and lithium, are relatively cheap and abundant.
Reminds me of cloud patterns. Like a time-lapse of Jupiter’s atmosphere.
well this is something
How much closer...?
Yeah yeah fusion energy is in our reach -1960s
55 years later, fusion energy is in our reach (v_v)
Tony stark did it in a cave! With a box of scraps
lmao XD
Well i am sorry. I am not Tony stark
i really wanted to make fun of it but marvel fans are so stupid they wont understand it
I am still hopeful that cold fusion is possible, even if it does not happen in our lifetime.
+Physics Videos by Eugene Khutoryansky
If it does... Wowee...
+Physics Videos by Eugene Khutoryansky Ignorance is bliss, no way. Wish for world peace, better odds.
+Physics Videos by Eugene Khutoryansky cold fusion doesnt even make sense lol, you don't get energy from slow moving atoms
Sorry to say that but this is a myth. Protons are repelling each other due to electrostatic forces. You need a lot of energy to overcome this barrier and make them join.
It's been 5 years guys
well, predict and then counter the turbulence ;D, like with weather
Almost here
I'm sorry I had some internet problems
The heat loss is probably due to parallel synchronized heat flow
Wait!! You can have turbulence at the scale of electrons?!
use the turbulence to your advantage
Finally, I can get back to the future.
It still consumes more energy than it produces. The reason for this is that the sun is much larger and has much more atoms, so quantum fluctuations actually become statistically significant, which makes fusion possible at lower temperatures. We don't have this possibility in comparatively small reactors on Earth.
+Taric Alani we STILL don't have...etc, never say never
+IImagnumalucardII I agree with you 100%. What we learn here is valuable information we can use to progress in science, engineering and technology.
Which came 1st ? The reactor or the Bomb.
Fusion is important, but not as an energy source.
It is important currently because solving fusion plasma confinement might help us solve some of the bigger problems in Physics, such as Turbulence.
It is important in the long run because if we do get it to work it will be an exceptionally good source of neutrons, which can be used to do all sorts of crazy stuff like stabilizing legacy nuclear waste, generating highly-pure nuclear fuel, and generating select radioisotopes or radioisomers with absolute ease. Granted, some fission systems could also do all of those things, but fusion would do it far more easily and in a highly-controllable fashion.
However as an energy source, fusion is nothing exceptional and perhaps worse than fission. Even if perfected, fusion will only produce 4-7 times the energy of fission per mass of fuel, while remaining much bulkier at about 1/3rd the energy density of fission. The neutronic capabilities of fusion will make it far more valuable as a partner to fission systems and as a producer of radioisomers for secondary nuclear energy systems such as nuclear batteries. It makes absolutely no sense to disregard those potential applications of fusion, especially when it doesn't stand a chance against the much more versatile and economical approach of using fusion to facilitate fission and radioisomer production.
Is France not building a fusion reactor and planning to start it in 2020? It is called ITER. If this is new technology breakthrough without which we cannot have controlled fusion, then how could ITER have been even started?
+Karolis Črn ITER is an experimental reactor, built with tons of diagnostic elements and is NOT a commercial fusion reactor (it will however output up to 500MW of power). The goal of ITER is to demonstrate that fusion energy on a near-commercial scale is possible and to adress some issues. These issues are scientific (turbulence, self-sustaining burning plasma) as well as constructional (tritium breeding, divertor technology, ...).
The discoveries made in the past 5 years concerning magnetic confinment fusion only support ITER and can greatly help to make the project a succes. They were not necessary to start up the project, but can surely contribute to attack the problems we have nowadays with fusion with full potential.
The ITER-site can help you with further questions or concerns, they are very generous with information concerning the technology and engineering behind this project.
As normal for the world's most high-tech machine, the schedule has suffered some delays. First plasma is now predicted for 2023 and first D-T reactions for 2027.
During the ITER-experiments, information from all over the world (Wendelstein 7X, K-STAR, JET, CCSF, MIT, ... and many other fusion reactors) is gathered to prepare for the next step to fusion energy: DEMO. A demonstrational reactor without all the diagnostic equipment to prove the feasibility (scientific, engineering AND economic) of fusion power. Depending on te results this will be either a tokamak or stellarator design.
+Wladyslaw Szpilman Thank you very much. This was not the first time when I hear a new breakthrough in the fusion energy field and when I am confused about the whole picture of the technology and our current progress.
Fusion is just a tactic to make weak gems stronger!
+SamSpellsGaming I don't get the whole message, can you explain? lol
+Denny Vlogs I'm assuming it's some video game reference.
The good news about fusion based power generation is that it is "just" an engineering problem, actually it has been just an engineering problem for a long time, after all we know for a fact that it works, just ask the sun. Look at how long we knew the science behind the internal combustion engine to how long it took someone to produce one that worked. The single biggest issue with fusion is funding. Governments are just now sort of taking it seriously, but still not nearly as seriously as they should, fusion will transform the world like nothing before it, even the printed word or the internet it really is that big. I would love to see every dime of NASA money diverted to fusion research for 10 years and every other dime we can divert to it. Finally, the Fusion guys need to spend some money on PR, all we see are these little blips once in a while and nothing that will stick with the average person, we need a moon landing spin put on this thing. They need to figure out how to get the public interested in an virtually endless support of comparatively cheap, safe, energy, even the Global Warming movement is all but ignoring it when ironically is would be the single biggest things to reduce GH gasses, bigger than everything else combined, solar, wind, tidal, geo-thermal...
What would you do if you had unlimited energy?

Like the sun.
Can't you ignore the turbulence and simply pump in more hydrogen?
📙
One step closer? Behind and in the wrong direction ;)
The sun actually fusions hidrogen atoms into helium atoms.
And maybe in another 40 years we might see a power plant........But I doubt it..... This a secure field to retirement program for physicist and researchers... Why mess up a good thing by solving the problem...........They should have solved this thing back in the 70's, or at most the 80's...............

Thermal seems so primitive. I hunch there is a wave/quantum mechanism that's incomparably better. Precisely orchestrated reaction, rather than messy thermal.
It's been three years, how's your research coming along?
Teslas torzions fields needs.

Co-existence? Maybe if you throw a branch of good'ol cannabis in the reactor, the "turbulence" will subside. I have HIGH hopes for hydrogen woot.
'murrica.
Thought um....They were closer to making fusing with people possible 😂😐
Same lol.
Well that's fantastic. So have we succeeded at a macro scale in making propellers that don't generate turbulence?
Asking for every water pump and outboard motor in existence.
This is important? What about my ex? I can't get over her. I am a peacock damn it, you gotta let me fly!
this is great maybe if people stop smoking our earth could be a pefect world-😎🌎
Um...doesn’t it take *four* hydrogen nuclei to form one helium atom, not two, as stated in this video?
+MarsFKA It takes two deuterium atoms to make helium. Deuterium is an isotope of hydrogen as it only has one proton and one neutron.
1+1=2. Tricky I know.
Hydrogen bombs produce a yield, but not a controllable one.
tokamaks wont get them there.
why cant i comment
Disliked for uploading an interlaced version.
Then you mean lockheed martin lie?
+batmanbegins72
This problem has to do with toroidal reactors. Lockhead is working on a different method.
+nustada what about the iter in france? is it not torodial ? where can i find more information?
batmanbegins72
What about it, that has nothing to do with your original comment.
If you want more information, learn some physics and get hired by LHM.

+Charlie Shin the problems with the earth (the changes to the worlds natural greenhouse/ice-age cycle) is not solely caused by peoples tobacco use, there are a lot more things affecting this. i.e. coal and gas power stations, industry, livestock(especially cattle), deforestation, rice pads and many many more
Sweggler but some are caused by humans
Charlie Shin i know that, especially the fuckwits who say, have massive plastic fueld bonfires, the factories in asia pumping out massive amounts of bad shit, humans have a lot to answer for. but my point is that we are not the sole cause of global warming and the earth's deterioration
Sweggler Oh well, at least scientist are finding a way to fix what others have destroyed
yep, and thats what im thankful for
