Superconductor Breakthrough Findings Replicated, Twice, in Preliminary Testing - Tom's Hardware
(www.tomshardware.com)
This is a most excellent place for technology news and articles.
The benefits of a room temp super conductor mean that it would be produced at scale for price points well above standard. It's that big a deal in performance improvement.
The paper's method is fairly messy, low yield, and brand new... But it's also not that complex of metallurgy afaik. I would not be surprised to see iterations on method that scale well.
Regardless: if it's true then it proves it's possible... Which wasn't guaranteed until now.
