The tech is actually not fine. The initial idea was that it would be a near vacume and that the sled would use air cushion to levitate. And that simply doesn't actually work.
That is why all of the companies doing it switched to maglev. And we know the issues with maglev.

- panick21_ 3y agoOh you mean the project that has been going on for like 40 years costs 100+ billion $ and isn't operational? Yeah works great. I hear they are gone install on in Hoboken soon.
- _fizz_buzz_ 3y agoNobody doubts maglev works (there is also a maglev in China and Germany also had a test track since the 80s). There are a lot of things that technically work, but are not economical. The math just doesn't add up to build this in any way that is economically reasonable.
