Question:
We were doing a science project on superconductivity and we were wondering what is the highest possible temperature superconductivity has worked at.



Replies:
Only 6 years ago, the highest known superconductivity temperature was very cold - around 30 degrees above absolute zero (That is Kelvin degrees, and is also around -400 degrees Fahrenheit). Recently discovered materials have brought that temperature up to about 125 degrees above absolute zero, or around -230 degrees Fahrenheit. That is a big improvement, but obviously is still quite cold. It is warm enough, though, that liquid nitrogen can be used to maintain the superconducting state, and liquid nitrogen is pretty cheap, so these materials are definitely a great discovery.
