Yep! This is one reason why I argue we should do lowish power density fusion, in space, using the vacuum of space. There’s a nice set of existence proofs, and the gentle magnetic fields do a much better job of confining energyhttps://twitter.com/michael_nielsen/status/1223291031338115072 …

What is the advantage of that over just big solar fields in space, and does it make the transport problem any less onerous than space based solar power?

Solar + ion drives are still reeeaaaallly slow just because of low thrust. Since aneutronic fusion has charged particles as an output, in principle this limitation can be avoided. But I don't have hard constraints on *why* current day ion drives are so low thrust
