It’s a newly proposed fusion reactor prototype. It’s a stellerator type reactor. Together with the Tokamak type reactor these two are the currently most promising types to achieve fusion and generate more energy than they take to operate. While the tokamakak type looks more symmetrical to the human eye the stellerator types have adopted very weird looking shapes where the symmetries are more hidden. The pictures are from this paper by mostly people from the institute who created the to date biggest stellerator type fusion generator Wendelstein 7-x. Their proposed prototype ‘Stelaris’ is a lot bigger than the 7-x.
Bonus (with little context):
And heres a shematic view oft how it would look like from outside. Just like a donut.
If you need me, I’ll be in my homogenized breeding blanket.
Some days you just need neutrons to smash you hard enough to produce tritium.
I’m sure it’s somebody’s fetish.
Make sure you wear protection of you don’t plan to have tritiums too young
Don’t forget to say no homo.
