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.
Depends. If your dick is made oft neutrons you can stick it it in the liquid Lead-Lithium mixture and produce Tritium. It would probably even be apreciated by the researchers since your making fuel for the fusion reactor. If its a normal dick I'd not recommend it though since it can be highly toxic. As to where to find it I have to disiapoint you. The reactor is currently still being desinged.
