Life gets difficult for this model because the heat induced due to current 'turbulence' and maybe skin effect gets 'stuck' inside the chamber. Fun engineering problems.
Even more Sci-Fi (I think; I couldn’t find definitive figures as to the size Teraloop aims for): https://www.ecn.nl/news/item/floating-train-at-2000-kmh-set-.... I don’t know whether that idea died on the drawing table since 2015, but I guess it could have.
