😂 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.
Comment on Hyperloop One to Shut Down After Failing to Reinvent Transit

Boo. All I want is fast as fuck transport. I don’t see why maglev trains in a vacuum are so difficult

And even before that the Swiss seriously studied the possiblity and gave up.
Mojojojo1993@lemmy.world 1 year ago
Swiss are known for nazi gold and secret banks. Not really building infrastructure for the masses
Sekoia@lemmy.blahaj.zone 1 year 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?

telling me you’ve never been to switzerland without telling me you’ve never been to switzerland.
bitwaba@lemmy.world 1 year ago
Lol wat?
Their train infrastructure is fucking amazing.
Mojojojo1993@lemmy.world 1 year ago
So Japan has had maglev since the 90s. Explain?
Lanusensei87@lemmy.world 1 year ago
Their Maglevs are not Hyperloops…
Mojojojo1993@lemmy.world 1 year ago
I’m aware. That wasn’t the question
Mojojojo1993@lemmy.world 1 year ago
Obviously
Maggoty@lemmy.world 1 year ago
Maglev=! Vacuum. Elon promised an existing technology inside a vacuum.
Mojojojo1993@lemmy.world 1 year ago
I know
nelly_man@lemmy.world 1 year 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.
Mojojojo1993@lemmy.world 1 year ago
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 ?

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.
r00ty@kbin.life 1 year ago
But! It's just like an air hockey table! I swear it's not difficult! :P
chitak166@lemmy.world 1 year ago
It sounds pretty complicated Elon!
banneryear1868@lemmy.world 1 year ago
Most engineering channels on YouTube. Guess thunderf00t has made progress recovering his public image.
chitak166@lemmy.world 1 year ago
He’s always been an OG.

Honytawk@lemmy.zip 1 year ago
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.
Mojojojo1993@lemmy.world 1 year ago
Except it would be 10 x faster. Bit fair enough
Thorry84@feddit.nl 1 year ago
Engage your brain please
Mojojojo1993@lemmy.world 1 year ago
Seems rude.
Mojojojo1993@lemmy.world 1 year ago
Take a flying leap please
metallic_substance@lemmy.world 1 year ago
[deleted]Mojojojo1993@lemmy.world 1 year ago
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.
kameecoding@lemmy.world 1 year ago
How about a 10 minute video about it?
Tnaeriv@sopuli.xyz 1 year ago
Such as having to withstand over 100 tons of air pressure per square meter
meeeeetch@lemmy.world 1 year ago
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.
rottingleaf@lemmy.zip 1 year ago
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.

I think you were being sarcastic with that last line and nobody caught it. Sorry mate.
Huschke@lemmy.world 1 year ago
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.

Don’t bother asking here, people on Lemmy blindly hate anything that has anything to do with Musk
Kbobabob@lemmy.world 1 year ago
There’s a whole lot to not like though. Are you saying people aren’t justified?
nova_ad_vitum@lemmy.ca 1 year ago
I don’t see why maglev trains in a vacuum are so difficult
Then make it.
Mojojojo1993@lemmy.world 1 year ago
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
exu@feditown.com 1 year ago
Maintaining a vacuum over long distances is really fucking hard.
You’d be better served utilising existing rail infrastructure and improving that to make high speed trains possible.
LEDZeppelin@lemmy.world 1 year ago
Whole purposes of hyperloop was to derail any constructive debate on existing rail network. Pun intended. I’d say hyperloop was quite successful.
fosforus@sopuli.xyz 1 year ago
The role of government needs to be entirely about removing obstacles on private entities that try to create new (or old if that works better) methods of transportation. If they let this fucking guy, or any other fucking guy talk them into anything, they’re doing their job wrong. Even if Elon Musk is a persuasive person, this is almost entirely a failure of government.
Mojojojo1993@lemmy.world 1 year ago
Small vaccum then. They managed to build a tunnel between France and England. Put people on the moon. Can do a lot
echo64@lemmy.world 1 year ago
We do one thing. Must do other thing. Smart.
