And it's been almost 100 years since the first patent (1934) on maglev trains, as built in 2002 in Shangai. That's why lay people wonder about not seeing scientific progress since the 70s or 80s - it seems like decades since giant steps were made. But incremental progress adds up, too. One day we'll merge all those low-temperature superconductor or graphene experiments into something bigger. And there's been a bunch of nice proofs coming from random places annually. https://en.wikipedia.org/wiki/Maglev#First_maglev_patent https://en.wikipedia.org/wiki/Maglev#First_maglev_patent
