Ok so this video convinced me hyperloops are a bad idea because vacuum is difficult to maintain

well then what’s a good idea that can go faster than airplanes? What am I supposed to be excited about instead? I love trains and the hyper loop sounded like a really fast train, which is cool.

Maglev, they hold the current rail speed record with 603 km/h: https://en.m.wikipedia.org/wiki/Railway_speed_record

By comparison the cruising speed of a current airliner is ~900 km/h

Maglev is expensive both to build (because you need magnetized rails) and to operate (uses more energy overall than a shinkansen).

There is a reason why Japan built a prototype decades ago but never built a commercial line.
