😂 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.
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?
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.
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.
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.
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?
Not mentioning that making tunnels for rail in rocky areas is already hard. And modern railways are not something simple or easy. That’s without space tech from futurism-themed magazines for teenage boys.
A normal (not high-speed, not something like TGV) railway line getting you from A city to B city 20% slower than a car, departing 5-6 times a day evenly distributed, is already an enormous dramatic change.
So basically every project worth doing. Obviously it would be expensive it’s train travel. Any kinda project costs a fuck tonne. Not specific to Hyperloop.
That’s fair enough. I suppose any kind of improvement on maglev would be useful. Just bumping trains to 300 would have some ability to compete with air travel
Yeah that would be very expensive and difficult. However kinda similar to if a plane fails.
All others seem fair enough. Technology moving past is kinda silly. That’s like saying don’t make trains as new tech might come and then it’s a waste.
If only I could. My life’s goal is that. To build what nobody else will. Unfortunately I must acquire great wealth in order to do that. Proving particular difficult. Still have some years left.
Boo. All I want is fast as fuck transport. I don’t see why maglev trains in a vacuum are so difficult
😂 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?
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?
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.

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.
Knowing when you are a cunt is difficult too.
Kool story bra. Tell me more of your intelligence
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…
Obviously
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.

They gave you the only answer your stupid question deserves.
Oh name calling. How very thoughtful of you.
Clearly very smert
Maglev=! Vacuum. Elon promised an existing technology inside a vacuum.
I know

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 ?

Of course. What a thiccy

Because maintaining a train length vacuum is really difficult and doesn’t really provide that big of a benefit.
Atmospheric rail has been attempted with varying degrees of success (but never to a ‘replaces traditional rail’ degree) for 200 years.
Not mentioning that making tunnels for rail in rocky areas is already hard. And modern railways are not something simple or easy. That’s without space tech from futurism-themed magazines for teenage boys.

Such as ?
Keeping a vacuum in a big area is extremely inefficient and energy costly, because it is impossible not to have leaks.
A tube for 6-8 people doesn’t come close to the capacity of a train.
During an emergency, the people in those tubes are stuck with no way to get out, unlike a train.
Hyperloop is basically a fancy looking but worse train in about every aspect.
Except it would be 10 x faster. Bit fair enough
Engage your brain please
Seems rude.
Take a flying leap please
How about a 35 minute video about it?
https://youtu.be/RNFesa01llk?si=haCoCDo5oc1Or8JT
Such as having to withstand over 100 tons of air pressure per square meter

Thunderf00t has many videos on the subject. I recommend checking them out. He’s been calling out musk’s bullshit for years, and is right every time.
But! It’s just like an air hockey table! I swear it’s not difficult! :P
It sounds pretty complicated, Elon!
Most engineering channels on YouTube. Guess thunderf00t has made progress recovering his public image.
He’s always been an OG.
Hyperloop ate half a billion $ and the only “transport” they managed to actually build is THIS

I think you were being sarcastic with that last line and nobody caught it. Sorry mate.
Read the rest of their posts. It doesn’t seem like they’re being sarcastic.
Do you also believe the Moon is made from cheese?
I want to believe.
Then make it.
If only I could. My life’s goal is that. To build what nobody else will. Unfortunately I must acquire great wealth in order to do that. Proving particular difficult. Still have some years left.
Then I can implement my manifesto
Don’t bother asking here, people on Lemmy blindly hate anything that has anything to do with Musk
There’s a whole lot to not like though. Are you saying people aren’t justified?
