There are no room temperature superconductors. They are theoretically impossible. All reports of them have never been corroborated. The explanation would take hours, but Keith Johnson solved the problem in 1983 in the Journal of Synthetic Metals volume 5.
There are numerous magnetic anomalies that seem like a Meisner Effect, but they do not share all of the attributes. ________________________________ From: Jed Rothwell <jedrothw...@gmail.com> Sent: Monday, July 17, 2017 1:56 PM To: Vortex Subject: Re: [Vo]:Rossi versus Darden trial settled I wrote: I do not think there is experimental evidence for this, I suppose because it would be difficult to test for. Difficult because, presumably, in the cathode only microscopic domains of nuclear-active spots superconduct. Not the whole cathode. I think that finding a tiny amount of superconducting material in a sample that is 99% not superconducting would be difficult.
