Why are maglev trains still rare? (lemmy.ml)

They were invented decades ago.

They have fewer moving parts than wheelbois.

They require less maintenance.

There's obviously some bottleneck in expanding maglev technology, but what is it?

We don't have yet room temperature Supra conductors, it's also why there was so much buzz about LK 99 this summer

Technically.... We actually do, but not simultaneously room temperature AND room pressure. There's one known material known to be superconducting at absolutely insane levels of pressure. That's not sustainable for any reasonable usecase of superconductors.

What happened with that by the way? I'm assuming since I haven't seen huge headlines since, it's not been replicated or it's been proven to be a hoax

Not replicated, they found some anomalies in the samples skewing the results

Thanks for the summary and the links!

It was basically proven not to be a super conductor
