Can you explain why -160c is a measure of success when the claim was room temperature? A super conductor functioning at -160c would make MRIs simpler, but it's not world changing.
because it's a very unexpected result, it shouldn't be levitating at room temperature and the random drop in resistance at certain temperatures doesn't make sense
Does anyone know what S.R. Hadden has been up to lately? A new high-temperature superconductor seems like the perfect cover story for a fraud scheme around room temperature superconductors.
I don't think -160C would change much since it would still need cryogenic cooling. Liquid nitrogen is the most common and cheapest cryogenic. YBCO is liquid nitrogen cooled and has the advantage that can make in large quantities and has high field strengths.
But if it was slightly warmer, over -153C, then it could use non-cryogenic refrigerants.
