MIT Professor Explains Nuclear Fusion in 5 Levels of Difficulty | WIRED
Nuclear fusion underpins some of the most basic processes in our universe and holds the promise of virtually limitless, clean, carbon-free energy. Dr. Anne White, Professor of Nuclear Science and Engineering at The Massachusetts Institute of Technology, has been challenged to explain the nature of nuclear fusion to 5 different people; a child, a teen,…

You’re putting a black hole in a jar. A star is nothing but a black hole that has created elements on its surface turning it into a light bulb. The surface starts with neutrons and the beta minus decay reaction does the rest. The end is a solid object like our moon.
Fusion has no natural catalyst. When quarks get separated, like when lightning creates gamma rays or particle colliders create unbelievable energy, it is the density of space that is able to overcome the strong force and keep the quarks apart indefinitely as a black hole or in milliseconds at a particle collider. It is the field of space that is the true energy of the universe. It’s absolute zero, bends light, and gives different forms of electromagnetic radiation different speed limits. The true strong force is between quarks and the particles of space which is a static, extremely pressurized, absolute zero field of sterile electron neutrinos. Without the field, nothing would exist.

Hey 👋
No one can give me an answer for this because it’s niche but,
Is a dual stage fusion possible
1}Helium=Hydrogen + Hydrogen
2}Helium=Hydrogen + Hydrogen
3}Helium+Helium= Beryllium
Is the energy released when doing 3} exponentially greater than just doing 1}
(I know it’s not this simple they don’t make helium when doing fusion)
My simplest question is would doing 3} (doubling the process of hydrogen fusion) be worth it?
Matt
July 19, 2023 at 5:13 pm
I think basically the amount of energy which you would need to perform Helium fusion is so insanely huge that it’s just not really possible on Earth, or at least will take so much energy to create the conditions we will never be able to reach breakeven where we get more energy out than we put in

Wait so basically fusion produces huge or enormous amounts of energy enough to make electricity production wayyy better and more efficient, eventually cheaper, and to get that you’ll need the plasma state and you’ll have to be able to keep those energetic particles under control, so what in summary is the exact issue they’re facing . Is it about getting the particles under control or finding ways to get more energy plasma state or?? I didn’t quite get that.
Taylor Salva
July 20, 2023 at 8:16 am
I think it’s the confinement of the plasma, as in holding it in the device. As it stands they haven’t been able to hold the crazy hot plasma for more than a fraction of a second
Orazio Vescovi
July 20, 2023 at 6:08 pm
they have been able to hold it for quite long, up to 10 minutes (!) I believe, but we still lack the instrumentation able to withstand the heat produced: most of the existing thomawaks are lab instruments and not made to actually harvest the heat as they would in a real powerplant. They actually have to manually shut the reaction down not to melt the instruments.
Beyond that, the issue is harvesting the energy – it requires tremendous amount of energy to kickstart the reaction. there is a relatively small margin of net energy that we can harvest, but the net balance is currently negative

She is a bad teacher but here is level 1
Fusion is joining atoms . Like Goku and vegeta joins to make Gogeta and sometimes Vegito
Level 2 Joining atoms is not easy ,You need to create extreme conditions. More the atomic number the more energy is req to do fusion. So we choose Hydrogen .
Level 3 We need the isotopes of hydrogen,We accelerate them and make them hit each other. Same charges repel so nucleauses of two iso dont want to join as same charges repel. As electrons also repel.
Level 4 Electron problem is solved using plasma where heat is so much that electron flow freely .
But nucleus still dont want to join ,there we req high pressure.
Level 5 – Fusion produces many new atoms ,Also the Iron which is most stable and thats when fusion dies. Fusion needs very high energy to rels energy. So its not stable .
Level 6 No one gonaa understand mathematics

MIT Professor Explains Nuclear Fusion in 5 Levels of Difficulty | WIRED
My name is Anne White. I’m a professor of nuclear science and engineering
at MIT. And I’ve been challenged today to explain nuclear fusion in five
levels of increasing difficulty.
Fusion is so exciting because it is extraordinarily beautiful physics,
which underpins some of the most basic processes in our universe. Nuclear
processes has a tremendously valuable application for humankind, a
virtually limitless, clean, safe, carbon-free form of energy.
Johan Lindeberg
July 26, 2023 at 6:19 am
24:12
Conclusion:
– Fusion energy research is an extraordinarily exciting field that is pushing the frontiers of
what we can do experimentally as well as what we can do computationally. Fusion might
be closer than we think and tremendous advances are being made every day.

“All the pieces of the puzzle are here” sounds good, but is it true? For example tritium breeding is a massive problem requiring tonnes of lithium isotopically enriched to increase the Lithium 6 percentage – and there is no viable process to do this easily. If it can be done, the costs will be astronomical.

Not a very good explanation for a 9 year old. Didn’t have a baseline of what the child knew and had to circle around multiple times. How about you start with the concept of an atom instead of talking about a star in a jar? Stick with teaching university students.

Ok… Well I didn’t expect to understand and have knowledge of every level I knew I had a good grasp but I didn’t think my understanding was quite as strong as it is. It really helped me put my understanding of the field in perspective, I still have some things to learn about but not as much as I expected.

Usually in this series, the undergrad is a science major, but I am deeply skeptical the undergrad in this video took freshman physics.

I don’t mean the following statement as an insult; it’s just a curious observation: I’m amazed at how knowledgeable and smart she seems while also sounding (to me) as if she wasn’t.
It’s the combination of the dialect with certain inflections (e.g. making a statement sound like a question by raising the pitch at the end of the phrase), filler words (so, actually) and lack of narrative structure in explanatory sentences (ice cream comes in many flavors, so there’s strawberry, what we call this is a freezer so that means there’s only cold food in there).
She certainly knows her stuff and she starts sounding intelligent when she talks faster and doesn’t break things down. I found that curious. It was as if she didn’t know how to scale down and was struggling too hard to be understood by laymen to a point where she ironically became hard to understand while the undergrad was very clear and logical, which felt like a sharp juxtaposition to me.
Fascinating topic, good video, like the content, like the people.

0:57: 🌟 Nuclear fusion is a clean and limitless form of energy that involves bringing particles together to release energy.
4:03: 🔬 Plasma is the fourth state of matter, and it can be controlled using magnetic fields.
7:17: ⚛ The tokamak is a device used to confine and control a super hot plasma in order to harness fusion energy.
10:51: 🔥 Fusion requires high temperatures and densities to make particles collide and fuse, producing energy that can be converted into electricity.
15:01: 🔬 Fusion energy sources, which are predominantly fully ionized plasmas, have a lot of mystery around them due to the complexity of turbulence and magnetic fields.
18:06: 🌪 Turbulence in plasma physics is a complex and visually beautiful phenomenon that affects the performance of fusion reactors.
22:09: ⚛ Fusion energy research is accelerating with the involvement of private companies and advancements in other fields, bringing us closer to achieving fusion electricity on the grids.

Nuclear fission and fusion are redundant. Why? Limited Fuel Supply: Fission relies on finite resources such as uranium and plutonium, which are not renewable. There are concerns about the availability of these fuels in the long run. Especially for the cities.
