Yep! Successful realization of a practical use nuclear fusion reactor would be--DING!--We are now a type "1" Kardashev civilization. We are producing energy without the need for nonrenewable (fossil fuels) or even renewables (wind and low level efficiency solar). We are harnessing the power that runs a star to produce the bulk or even _all_ of the energy needs on Earth. One reactor could not do this, but you can guess that such a technology would by necessity scale up pretty quick. Having said that about "low level efficiency solar" (LLES), if we manage to achieve a certain level of efficiency, I think it is like 70% (?) conversion, then we have also become a T1K civilization as well. Cuz the sun is a perfectly good practical nuclear fusion reactor if you can get more energy from the sun than the energy needed to _obtain_ that energy. Today we are abouuut at 24% conversion efficiency--which is a huge jump from even 10 year ago--10%. Twenty years ago it was bout 5%. With new improvements and insight into Perovskite technology, I anticipate substantial number improvement beyond anything we have ever seen before, well before the year 2030. Closing in on 70% by then. (Today we are a type "O" Kardashev civilization. We use earth based fossil fuels, wind, geothermal and LLES.)

So before we were whole 30 years away from fusion, but thanks to this super amazing breakthrough with AI we are only 30 years from fusion!

This isn't about running something for the longest, they're not functional reactors. This is about proving the science and the engineering to come to the best result. There's a good chance they could have left it running for more than 5 seconds, but they didn't need to do that prove the result, and doing so would likely damage components not intended for that longevity.

8:01 That 50-in/500-out figure refers specifically to the plasma reaction, not the device as a whole. The magnetic fields, cooling for superconductive magnets, pumps for steam, pumps for plasma injection, monitoring equipment, control computers and all the other incidentals are not accounted for in the 50Mw number. All up ITER is expected to use more than 350Mw of electricity to run, with peaks of up to 620Mw. Additionally engineers have to account for the efficiency of turning that plasma heat energy into electricity. A very efficient turbine in a modern nuclear reactor can achieve 33% efficiency. Using these numbers, a reactor based on ITER would be able to generate 165Mw, significantly less than what it takes to run. If ITER is able to achieve the predicted numbers, it'll be a major breakthrough. But we'd still be at least two research reactors away from a working prototype fusion power plant. If they take the same amount of time to build as ITER itself (and they'll probably take longer), that puts us at least 25 years away.

As for ITER, there are 7 founders : China, the European Union, India, Japan, Russia, South Korea and the United States. When ITER finally does become operational, these 7 countries will share the technology. So, there's really no competition in the nuclear fusion race. Just wanted to say that so that people don't turn this entire thing into a competition. I believe other countries are also involved as well, but I don't know if they will get the technology when this is all done. There's also private companies working on this technology too, but they are small players.

The people who keep joking that it's always 30 years away are getting quieter now that there's a new breakthrough every single month. There are already whispers that when ITER is finally complete and a few tests are done it could be ready to start producing energy within months, if we can successfully implement all the results of all these breakthroughs into the design. As someone who follows this science quite closely it's really been quite remarkable how much has been achieved in just the last year. It's also important to note that the tests so far have been limited (but amazing) by design. The capabilities of the test reactors are limited, they're intended as proof of concept and delivering the results we really wanted to see.

This is the best news story I've been following for the last year. With all the heartache we hear about on a daily basis this is the beginning of a totally different world. Truly hoping to see fusion working within the next 10 years.

I gave a speech in my 1981 High School speech class about Fusion power. All we had to figure out was the plasma containment problem even back then.

Good question! They're using technology called "heat blankets" -- basically it's like we do with anything else that's hot. The tokamak's burning plasma generates heat, and stray the neutrons from the reaction collide with lithium, also generating heat. To capture the heat generated we'd run a cold liquid through the "heat blankets" which aren't really blankets, more like heat absorbing walls. The cold liquid runs through, picks up the heat. That now-hot liquid then keeps water boiling in a pressure vessel, and the steam turns a turbine that generates the electricity.

there's a ton of ways that are being tried. General Fusion's piston compression looks promising as a non-tokamak option too. Commonwealth Fusion out of MIT is a smallish Tokamak that can probably get it done just thanks to the stronger magnetic fields thanks to the latest high temperature superconductors. And then there is HB11 that may have a real shot at making an advanced form of fusion that is almost to other forms of fusion what those fusion reactions are to fission (no neutrons and the charged particles can be directly captured to create electricity so no turbines and whatnot, magnetic confinement is secondary to capture the particles not to generate fusion, can be made very compact for things like ships and spacecraft, maybe even aircraft, and just uses ordinary hydrogen and boron as fuel)

Because AI can learn much more quickly than humans we will only always be 30 weeks away from achieving sustained fusion.

These need to be the focus if we really want to eventually stop depending on fossil fuels.

I think the important thing here that everyone seems to be missing, is that we can now make helium. Therefore, party balloons are saved!!!

1980 -- "Fusions is just 20 years away!" 1990 -- "Fusions is just 20 years away!" 2000 -- "Fusions is just 20 years away!" 2010 -- "Fusions is just 20 years away!" 2020 -- "Fusions is just 20 years away!" Are we beginning to sense a pattern here? This is not to say that fusion will NEVER come -- centuries from now, the 20 years may finally run out. But chasing fusion is like climbing to the top of an enormously tall tree to pick an apple while totally ignoring the big and juicy fruit on the lower branches. We live in a world with limited resources. It makes no sense to spend those resources on pipe dreams while ignoring practical solutions to our problems just because they aren't "sexy." For instance, if we had put a tenth of the resources spent on fusion research into designing off-the-shelf fission reactors (especially thorium reactors), we would have already solved our electricity problem for the next few thousand years. But then, "researchers" and "research companies" would not have been able to milk the taxpayers for billions with absolutely no practical results.

Tritium is from water for hydrogen. But fusion needs deuterium with hydrogen is needed for stable plasma. So a tokamak has to have fields to create deuterium. The only one with this system is ITER.

What an extraordinary presentation to talk about fusion energy without mentioning tritium. Given that the primary fusion candidate is the DT reaction, about 100 times easier than a DD reaction, to claim that the fuel comes from seawater is plain nonsense. There is virtually no tritium in seawater, and instead it needs to be produced in heavy water fission reactors. Only very small quantities are available, probably not enough to start a fusion reactor.

I've been following Fusion for a couple years now. "Q" is the variable used to denominate "Positive energy output". It is theorized that Q+50 is the 'break-even' point where the heat from a Tokamak can sustain itself, and all the ancillary systems, and produce net positive output. The delays in bring Q+ Fusion commercially are purely based on scientific funding. The science is sound, and with more capital, breakthroughs in superconductivity and AI such as mentioned in this video could have come sooner. There is a shift in the wind, and this is evidenced by the new influx of Series B and other massive amounts of research money being pumped into private companies such as Commonwealth Fusion and First Light. US$1.2Bn to Commonwealth alone. Recent breakthroughs with superconductive, high-power magnets have already obsoletizied(made up word) those built for ITER. EAST in China has already used this new technology to maintain a 16-minute reaction. There is a massive ramp-up of private funding by people and companies who are apt to throwing money into black holes. Who knows when Q+$ will happen, but I predict that it will be before 2030 for sure, and it may even be 2025-7.

Fusion opens many doors that simply aren't attainable because the energy costs are too high. Also, spacecraft with fusion propulsion are theoretically significantly faster and more powerful making the commercial space industry far more viable. The possibilities are near endless

When you realize the magnitude of complexity it is to build a fusion reactor there won’t be many built. Most will cost more than the GDP of a small country let alone a the city it would power. A proof of concept reactor is minuscule compared to a commercial power plant.

I totally agree with you - I could have been more clear. I’m a huge fan of fission as a power source!

People often only associate fission to nuclear bombs but, Hydrogen bombs or fusion bombs are the epitome of nuclear bombs. They literally use a fission bomb to jump start a fusion reaction, or a chain reaction of them, which in turn leads to a much more energetic explosion. Which just goes to showcase the energy capabilities of fusion power. Personally i'd change all fossil fuel energy plants into modern nuclear (fission) plants, which are considered to be almost infallibly safe and all available scientific demonstrates them to be considerably less toxic than even conventional forms of renewables, in order to have a cleaner transition from fossils into fusion (hopefully). The prospesct of having clean abundant and cheap energy in 20 - 40 years is enticing but we never know what hurdles lie ahead and well ... Look at the world right now, a mistep in geopolitics could send fusion reasearch down the list of priorities. We already have safe reliable and clean fission technology right now, why not use it?

I hope I live long enough to be able to look back and pinpoint precisely which "we are only 30 years away from fusion" claim was actually correct.

Y'knowwww, Trace, if we could tap into _your_ energy...

BTW, that scenario you describe @6:20... totally dystopian. Does that really happen?

Can they capture the helium byproduct, and store it? It’s finite as of now.

Fusion is as significant to the human race as fire.

They probably wont get it until they figure out how to get rid of the "hole" in the donut. Focus more on the field confinement and get rid of having a structural column in the way. Magnetic fields should be able to span the center gap on their own, the trick is more on structural engineering to "pry" the halves apart so it doesn't collapse from the fields with that interfering piece out of the way. Radius and separation goes to zero in what should be the hottest part and the efficiency would go significantly up.
