Yeah I’ll get excited after it gets peer reviewed
It’s already been published. But it’s superconducting at 10 K. This is a new high temperature record, but pretty far from room temperature.
Yeah the headline makes you think it's even within "normal" temperatures, and then you see that it's like 10°C ~~below~~ above Absolute Zero.
Nitpicky but it's above absolute zero
Even if it was somehow 10° below absolute zero, it would still be 10° above absolute zero
I thought negative Kelvin were sometimes used to describe very very high temperatures but I could be wrong.
Thanks for the downvotes y'all, enjoy being wrong:
" Negative absolute temperatures (or negative Kelvin temperatures) are hotter than all positive temperatures - even hotter than infinite temperature."
Yeah what happened to that one out of South Korea?
superconducting below 10K or -263C. a record but by no means room temperature.
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.
