…“Once you have super-conducting technology available in space, you can then create very strong magnetic fields and you can use them for various use cases,” he said. “You can accelerate things in space very fast or change the trajectory of a satellite completely without fuel.”…
“When we go to space, we get hurt by radiation, and these superconducting magnets can create umbrellas of magnetic fields around the spacecraft to protect the interior,” said Arshavsky. “So we can shield people in space from that radiation.”…
They’re not claiming the launch won’t use fuel, just manoeuvring in space, which still solves the problem of getting fuel for manoeuvring while in space. Fuelless launches are a separate issue that other people are working on.
