Fusion! Unlimited power! Superconductors! Yeah, this article is easy to dismiss as spin on fusion tech that is perpetually just ten years away. But two interesting things about this particular design: It uses new commercially available superconductors made of rare-earth barium copper oxide (REBCO) superconducting tapes that are capable of producing high-magnetic field coils. The stronger magnetic fields generated by these coils do a better job of confining superhot plasma, so the reactor can be smaller, cheaper and take less time to build.
