U.S. Govt and researchers seemingly discover new type of superconductivity in an exotic, crystal-like material — controllable variation breaks temperature records
Loads of things superconduct below 10K - aluminium for one. This is for a different type of superconductor that can be turned on and off with a magnetic field.
Not quite in the usable temp for engineering yet but definitely on the right path. And a wee bit less sketchy than the last one. That combine with the progress is fusion reactors. We have a bright future in energy ahead of us (but pretty grim everywhere else)
Very cool, I didn't know a toggleable superconductor was even possible. With all this research into superconductivity it's only a matter of time before a room-temperature superconductor is found.
