I would be curious if anyone with knowledge in the space could comment on whether or not LK-99 may get us closer to viable nuclear fusion?

My understanding is that magnetic field containment systems are at least part of the technical hurdles required to make fusion feasible.

So far lab replication efforts are: Two from HUST: https://www.bilibili.com/video/BV14p4y1V7kS/ https://www.bilibili.com/video/BV13k4y1G7i1/ One by USTC https://www.bilibili.com/video/BV1Ex4y1X7ix/ this tiny sample can stand on its pointy side. One by Qufu Normal University https://www.zhihu.com/zvideo/1669820225079070720 One with THU background but claims a personal project https://www.bilibili.com/video/BV14z4y1s7V…

The vast majority of science does not take place on Twitter.

Depends it's wet lab science or dry lab.

but it's a growing trend anyway.

Twitter is just one of those communication platforms.

There is an anthropic line of reasoning over Everettian branch universes where you can actually expect these types of highly unlikely events to happen more often than chance alone would predict if they promote futures with more Born-rule weighted observer-moments.

Excellent insight and perspective.

>2) Commercially viable fusion energy. Will change a lot of things.

How would that be any better than commercially viable fission breeder reactors (which seem far closer to reality than commercially viable fusion energy)?

This is ELI5 stupid Q:

What may be the benefit of running a sequence of "coils" or whatever the Loops may be comprised of such that the N/S to whatever polarity positions are required, could be an LK-99 then a super cooled, then an LK-99 etc...

If it was in a toroidal spiral (everyone things of the trajectories as linear, but toroidals spirals are most efficient)

you could have hybrid tracks - where maybe a linear launch is good, but a toroidal control for spins off routing is ideal (think a 3d roundabout - to launch vessels diff directions...

A good one would be "productive AI." People forget, but a short while ago, AI was treated as something where being actually useful was perpetually 20 years away, and the real-world status of it was exemplified by a chatbot like Eliza.

Yea, Eliza is a far worse chat bot than ChatGPT… More seriously AI has made lots of things better, it’s really the hype cycle that’s disappointing. More FPS in games just isn’t as exciting as self driving cars. But by the time you can buy a level 5 self driving car the technology will be pedestrian.

When COVID hit, my American Airlines flight got canceled and when I went online to ask about getting credit, I got connected to a bot. When I asked to be connected to a real person instead of a bot, the person came online and said: "My name is Eliza. How can I help you today?" At this point, I was very skeptical, but she was indeed a person.

Commercially viable fusion can be achieved with commercially viable source of muons:

I hope they're as weak as possible. The worst possible outcome of a room temp superconductor being discovered is stifling innovation to make money off it

It would be the opposite. Nobody with develop technology to utilize it because there are no protections. No MRI, No Fusion, ect.

Bullshit, science isn't driven by patents or funded by private industry.

This sounds "right" but i have no idea what you mean.
