This alone cannot be a correct statement, because the 3. Law of Thermodynamics states that you cannot reach 0 degrees Kelvin. So I think we already got some working superconductivity at room temperature by that definition.
The author clearly has not the knowledge to write over this so I stopped reading there. Also it cannot be a typo, since he even explains the corresponding degree in Celsius

- James_K 2y agoI would say it's more obviously wrong because I've seen examples of ceramic superconductors cooled by only liquid nitrogen. A quick google confirms that cuperate-perovskite ceramic superconductors have a critical temperature above 90K.
