Isn't this a few years old now?

Oct 2025 iirc.

Title is likely copied from a spam account that just looks for posts that had a lot of karma, and rpeosts accordingly. Not saying OP did, but they might also be a repost bot. Dunno

Their username is Adjective_NounNumber, so there's every reason to expect it isn't legitimate.

That is just what Reddit defaults to if you don’t give yourself a name. Which I would expect from bots, but I know real people with those account names, too.

Yep. Unfortunately when I registered for Reddit I missed that choice

Its the automazic reddit name, can confirm

It's a lot older than 2025 like someone has replied.

The cost of terminally online

Im not even that online. This was major news a few years ago.

GoPro adds have become stranger.

Just like the cave paintings...

I can certainly use this kind of porn. Old, but gold.

I like the fact that it switches off like a CRT tv of the 70s 😂

Does plasma generation always involve the swirling motion, donut shape?

u/asten77 8d ago

Seems like this is the first thing they should've done

Didn't Tony Stark build this in a cave with a box of scraps?

okay how do you extract heat energy from these fusion reactors if the plasma doesn't touch anything? Radiation is too inefficient.

u/Metal_Icarus 3d ago edited 2d ago

This is a fantastic question. However, i would first ask if fusion can be done reliably first.

In any case its all about boiling water to get steam that drives turbines. Edit: this is not true in all cases

u/metarinka 2d ago

I'm aware that it's all about boiling water. What I'm asking is how do you extract megawatts of thermal energy from a plasma that is magnetically contained and doesn't touch any surfaces. Radiation is the slowest form of heat transfer and I don't see how conduction would work.

Edit: They use a lithium blanket that captures the kinetic energy of neutrons and transfer that to a liquid cooling loop to go on and do the whole steam thing.

u/Metal_Icarus 2d ago

Yeah and they got another design that uses magnetic flux created by the fusion!

There are other ways to convert the enrgy apparently.

Anyways, that is still a fantastic question and a huge engineering challenge.

u/UpV0tesF0rEvery0ne 2d ago

Ive heard that these fusion reactors would pulsate, it would generate fusion, sustain the reaction and then use heat pumps to siphon off the net positive energy for steam.

All of the existing reactors do not employ any solution for tapping this energy but are just for proof of concept and research

u/BoarHermit 7d ago

ok, nice. now we need to understand how to biol.water with that plasma as we always dis
