why the fuck aren't we putting a couple billion into ARC instead of wasting 30 years and 50 billion on ITER? Positive Q is extremely doable with ARC.
And no, "muh nτE" is not an argument

speaking of ITER, why do the french of all people get to have it on their turf?
Because french depend on nuclear power most.
Fuck fusion, it's a pointless distraction when thorium exists right now, is completely viable, and has all the advantages of fusion.
the future of energy lies in more than one power generation method. Thorium might be one of those, but fusion would be nice to have as well, no?
can ARC desalinate as well? one of the biggest bonuses of nuclear fission/fusion is desalinization. 2/3rds of the planet will run out of potable water by 2050. wars will be fought over water within our lifetimes. finding an efficient way to desalinate water is very important
Because the necessary advances in material science were made after ITER started; Also because having a prove-of-concept for more than one design is the non-brainlet move to do; Also because ITER has actually been proven feasible, instead of being a vague article on some shitty online platform.
I do feel as though fusion funding has been misleading as hell. How long have they known that all they needed was a superconductor that can generate high Tesla magnetic fields?
go ask the PSFC I guess
They're just very good with nuclear stuff. In the end of the 20th century, politicians decided to go full nuclear instead of flirting with the oil Jews (may have to do with their former colonies in other Arabic countries.)
Now they're one of the country in Yurop where the electricity produces the less CO2 per W while having with very low solar/wind. They're also the third country worldwide in number of nuclear/thermonuclear warheads, far behind USA/Russia. Obviously, all this goes with university, professors, labs, etc since it's been over a generation now.
Pic related, TGV is a corded nuclear train.
excellent talk on fusion (and a plug for ARC) youtube.com
Hey guys here is our pathway...lol
>wait for commercial company to make really great superconductors
>buy them and build a reactor using other off the shelf commercial parts
>laugh at the government for giving us billions for nothing
it's always been known how important magnetic field intensity is, especially in a toroidal configuration where instabilities and losses are accentuated. theoretically, available power is proportional to magnetic field intensity to the fourth power. so doubling it increases power by a factor of 16.
even still, the ultimate goal with devices like these is dominant alpha particle self-heating--that is, the helium produced not only releases more energy that was put it in, but it transfers enough kinetic energy to cause much more fusion. it's not 100% clear that this can happen, but we do know we need larger machines and or stronger magnets.
>stronger magnets.
Then why the hell didn't they spend 60 years getting funding for things that wouldn't work without powerful magnets?
France has a really good nuclear waste program. Contrary to the memes of fusion being a super clean technology, it still produces a fair amount of radioactive materials that need proper disposal.
Americans and jews wouldn't want that because most of world's thorium is in india and middle east, and mutts can't let others get ahead, which is why they have everyone sign treaties and agreements to not use thorium because reasons
Resources being located in foreign nations didn't stop America from 'securing' it in the past.
Cause we're good at complex engineering
There's plenty of uranium and thorium in the United States territory. No need for your bigoted conspiracy theories.
'Scaling factors'
Basically they see equations that look amazing on paper, and then think building the next machine will get them way closer. In reality, the properties of the plasma end up not scaling how those equations described. So they DID build machines with better magnets and were just disappointed.
How do we achieve a Q of infinity
>he thinks that a standard toroidal magnetic field will work
stellarator is way better and can sustain longer reactions by using a twisted field shape so it's equally spread
tell me, what’s the highest Q a stellarator has achieved? Tokamaks are currently the best bet, simply because it’s been tried and works, and there is a clear path to positive Q with the tokamak design (see: ARC)
Sure, other designs could be better long term, but that’s not important right now
The future will be a flexible smart grid with 80% renewables and 20% gas turbines fueled by CO2-neutral gas syntehsized with excess power from renewables in some power-to-gas process.
The age of nuclear power is ending.
Btw, why are nuclear plants' chimneys so big ?
they make a lot of heat
They're cooling towers. There is a massive amount of energy produced in the form of heat, and all of it can't be transformed into electricity.
Also they could make smaller cooling towers that work differently, not sure why they opted for the large ones.
