So Japan has had maglev since the 90s. Explain?
Comment on Hyperloop One to Shut Down After Failing to Reinvent Transit
314xel@lemmy.world 10 months ago😂 That’s what Muskrat wanted you to believe. Engineers and people with more than 2 neuron cells have debunked the Hyperloop idea for years. Here’s one of them from 7 years ago.

Their Maglevs are not Hyperloops…
Mojojojo1993@lemmy.world 10 months ago
I’m aware. That wasn’t the question
Lanusensei87@lemmy.world 10 months ago
It is the answer to your question tho. Maglev is feasible, Hyperloop, not so much.
WhatAmLemmy@lemmy.world 10 months ago
They gave you the only answer your stupid question deserves.
Mojojojo1993@lemmy.world 10 months ago
Obviously
Maggoty@lemmy.world 10 months ago
Maglev=! Vacuum. Elon promised an existing technology inside a vacuum.
Mojojojo1993@lemmy.world 10 months ago
I know
nelly_man@lemmy.world 10 months ago
The vacuum is the hard part, not the maglev. You would need to enclose the entire track inside if a vacuum, and that world be ridiculously expensive and practically impossible with current technology. It’s already very expensive to build a tunnel for a train, which is why they are avoided if possible. But this would need to be all tunnel that is air tight, so even more expensive than regular train tunnels.
To put it into perspective, the current largest manmade vacuum chamber is at a NASA research facility in Ohio. It’s a cylinder with a diameter of 100 feet and a height of 122 feet. If this were laid on its side, about 1.5 New York subway cars could fit inside. The largest vacuum ever made can barely fit the vehicle inside, let alone allow it to travel between two different places where the extra speeds would be warranted.

That kinda puts it in perspective. What about particular vaccum? Or just where the tracks meet the train. That’s the only bit with drag ?
OneCardboardBox@lemmy.sdf.org 10 months ago
The drag is air against the whole body of the train, so you need vacuum everywhere.
Assuming that you could build such a big vacuum there would be safety concerns. What if there’s an accident in the tube? Does everyone in the train depressurize and die? Assuming people can survive and get out of the train car, now they’re in a tube that’s 100 miles long. How can you build emergency exits in a system designed to be as airtight as possible?

And even before that the Swiss seriously studied the possiblity and gave up.
Mojojojo1993@lemmy.world 10 months ago
Swiss are known for nazi gold and secret banks. Not really building infrastructure for the masses
Sekoia@lemmy.blahaj.zone 10 months ago
Uh. Buddy. They absolutely are known for building a shitload of trains. There’s the Gottard, which is the longest tunnel through a mountain, and I think also the steepest railtracks in the world?
You’ve never heard of swiss trains always being on time?
Mojojojo1993@lemmy.world 10 months ago
Japanese trains being on time. Never heard of swiss.
Haven’t heard if their engineering prestige.
When I think swiss I think corruption and chocolate. Maybe watch makers too. Apologies
Serinus@lemmy.world 10 months ago
Don’t forget they’re also known for cocaine!
Gregorech@lemmy.world 10 months ago
Will the newly proposed tunnel under the Angeles National Forest break that record or because it’s under not through it’s in a different category?
lovesickoyster@lemmy.world 10 months ago
telling me you’ve never been to switzerland without telling me you’ve never been to switzerland.
bitwaba@lemmy.world 10 months ago
Lol wat?
Their train infrastructure is fucking amazing.
Mago@lemmy.world 10 months ago
Leave your state.

Don’t live in America. Leave your country
