Hyperloop One to Shut Down After Failing to Reinvent Transit::The company is selling assets, laying off remaining employees.
😂 That’s what Muskrat wanted you to believe. Engineers and people with more than 2 brain cells have debunked the Hyperloop idea for years. Here’s one of them from 7 years ago.
And even before that the Swiss seriously studied the possiblity and gave up.
Swiss are known for nazi gold and secret banks. Not really building infrastructure for the masses
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?
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
Well if you’ve never heard of it, then you must be right. Or it could be that maybe you have no clue what you’re talking about. No that couldn’t be it.
It blows my mind that you’ve never heard of Swiss engineering, but I guess the whole world is wrong since you’re clueless to it. Case closed.
He didn’t even think of the cheese! I don’t think he misses many mensa meetings
He’s never even heard of those idiots.
He relented. No need to go so hard. Try to have some empathy, even if his approach was wrong.
That wasn’t me going hard. I was simply meeting their dismissiveness with sarcastic dismissiveness as a way to show them their faulty logic.
Knowing when to shut up and when to listen are valuable skills that a lot of people don’t have.
Kool story bra. Tell me more of your intelligence
Knowing when you are a cunt is difficult too.
Don’t forget they’re also known for cocaine!
Lol I didn’t get the reference before
(There was a post about Switzerland considering legalizing cocaine cus they have so much and it’s so pure & common, apparently)
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?
telling me you’ve never been to switzerland without telling me you’ve never been to switzerland.
Lol wat?
Their train infrastructure is fucking amazing.
Leave your state.
Don’t live in America. Leave your country
So Japan has had maglev since the 90s. Explain?
Their Maglevs are not Hyperloops…
I’m aware. That wasn’t the question
It is the answer to your question tho. Maglev is feasible, Hyperloop, not so much.
And even maglev is barely done because it’s so expensive to build. Hyperloop is wrapping that same maglev train into a tube that should maintain a vacuum for kms on end, and pretty much every failure mode would end up being genuinely catastrophic.
Plus you would have to armor the whole thing and spend a bunch on security because one guy with a .50 rifle or some explosives could destroy a whole section and close the whole thing by punching one hole in it.
Haha, yeah. Remember the chaos when militia guys started shooting at transformers in substations? Every hick with a gun would be shooting at it just to shut it down.
They gave you the only answer your stupid question deserves.
Oh name calling. How very thoughtful of you.
Clearly very smert
Obviously
Maglev=! Vacuum. Elon promised an existing technology inside a vacuum.
I know
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 ?

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?
Of course. What a thiccy
