Which is unrealistic and expensive

and then you have to pump it all out after

a lot of designers are advocating for compartment seals in the case of train emergencies, but again, that's a real complication as well

Even if it was built

It's going to be far more expensive to ride than a subway

if it's built, it's going to need a whole new approach to safety

Which we don't have

we do

we'll see I guess

I guess

but hermetic seals in a tube? yes, we can do that

The real issue is that it would cost too much

To ride as well as build

I know it's crazy, but people thought the ATP or TGV were nuts when they were conceived in the EU

bullet train isn't so silly when you traverse half of japan in under 2 hours lol

A bullet train costs nowhere as much as the Hyperlop will

think you'd find the carriages would work out cheaper

the infrastructure would be the expensive aspect

**Emoished#9518** was cleansed from the server.

I still agree it's an expensive project, but it's entirely feasible

No material on Earth is strong enough to make a hyperloop tube, several million cubic feet of vacuum is impossible under earths atmosphere

but they're already making them? 🤔

Not to mention the fact that one crack will cause the entire Network to implode

we're not talking carbon nanotube level here

and they can still achieve impressive speeds without going full bore crazy

well within tolerances of even HY 80 steel or titanium forging in high speed sections

you want to build a space elevator? Sure,. Bakeon is right atm

you want to build a hyperloop? nah, not so right

cracks are an issue, admitted

easier to deal with though

especially with a fibrous outer layer pressurised within the outer shell

the biggest issues with these systems are energy/maintenance, that's my point I guess 😦

carbon nanotubes?

:smith:

https://en.wikipedia.org/wiki/Carbon_nanotube

like the ones in printer cartridges

bear in mind we've been able to ascertain these work

but we've not been really able to utilise it yet

the principles are sound though

tiny tubes

pretty much
