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

[-] exu@feditown.com 83 points 11 months 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 86 points 11 months ago

Whole purposes of hyperloop was to derail any constructive debate on existing rail network. Pun intended. I’d say hyperloop was quite successful.

[-] Mojojojo1993@lemmy.world 4 points 11 months 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 29 points 11 months ago

We do one thing. Must do other thing. Smart.

[-] CommanderCloon@lemmy.ml 21 points 11 months ago* (last edited 11 months ago)

Why not just make a tunnel and forget the vacuum? It's just a subway system, but it's efficient

Edit: France & England might have dug a tunnel but Paris and London just have a subway. And train to move around the country.

Edit2: fixed wording

[-] Thorry84@feddit.nl 19 points 11 months ago

No it's literally a subway system. Putting trains in tunnels isn't something new or revolutionary, that's literally what subways are. And we've been doing it for over a hundred years.

People seem to be locked in on examples in the US of bad subways to mean subways inherently suck. But there are plenty of examples of perfectly working subways, which are highly efficient, comfortable and get you from A to B fast.

There are even places with subways that currently suck, but used to be very good. But car culture has meant rich people use their car and sit in gridlock, while the poor use the subway. This lead to a class difference and the richer class in power gutting funding for public transport. That is what makes it suck, not the principal of the thing.

Everything Elon says is new or revolutionary, usually isn't. The hyperloop (or vacuum train) concept isn't new either, I remember reading a book in the 80s where they had vacuum trains. And there are examples of the idea going back a hundred years or more. The hyperloop idea is so dumb, it can be debunked in a couple of minutes with some back of the envelope calculations. The power requirements alone would be huge. But hey slap some solar panels on that bad boy and it regenerates it's own power right, cause that's how anything works.

😂 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.

[-] ours@lemmy.world 20 points 11 months ago

And even before that the Swiss seriously studied the possiblity and gave up.

[-] Mojojojo1993@lemmy.world 3 points 11 months ago

Swiss are known for nazi gold and secret banks. Not really building infrastructure for the masses

[-] Sekoia 46 points 11 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 6 points 11 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

[-] ericisshort@lemmy.world 41 points 11 months ago

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.

[-] the_post_of_tom_joad@sh.itjust.works 7 points 11 months ago

He didn't even think of the cheese! I don't think he misses many mensa meetings

[-] SinningStromgald@lemmy.world 7 points 11 months ago

He's never even heard of those idiots.

[-] Serinus@lemmy.world 5 points 11 months ago

He relented. No need to go so hard. Try to have some empathy, even if his approach was wrong.

[-] ericisshort@lemmy.world 2 points 11 months ago

That wasn’t me going hard. I was simply meeting their dismissiveness with sarcastic dismissiveness as a way to show them their faulty logic.

[-] Nudding@lemmy.world 11 points 11 months ago

Knowing when to shut up and when to listen are valuable skills that a lot of people don't have.

telling me you've never been to switzerland without telling me you've never been to switzerland.

[-] bitwaba@lemmy.world 23 points 11 months ago

Lol wat?

Their train infrastructure is fucking amazing.

So Japan has had maglev since the 90s. Explain?

[-] Lanusensei87@lemmy.world 44 points 11 months ago

Their Maglevs are not Hyperloops...

[-] Mojojojo1993@lemmy.world 3 points 11 months ago

I'm aware. That wasn't the question

[-] Lanusensei87@lemmy.world 50 points 11 months ago

It is the answer to your question tho. Maglev is feasible, Hyperloop, not so much.

[-] jonne@infosec.pub 16 points 11 months ago

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.

Maglev=! Vacuum. Elon promised an existing technology inside a vacuum.

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.

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 4 points 11 months ago

But! It's just like an air hockey table! I swear it's not difficult! :P

[-] chitak166@lemmy.world 2 points 11 months ago* (last edited 11 months ago)

It sounds pretty complicated, Elon!

[-] banneryear1868@lemmy.world 2 points 11 months ago

Most engineering channels on YouTube. Guess thunderf00t has made progress recovering his public image.

[-] chitak166@lemmy.world 2 points 11 months ago

He's always been an OG.

[-] meeeeetch@lemmy.world 19 points 11 months 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.

[-] ThunderWhiskers@lemmy.world 11 points 11 months ago

I think you were being sarcastic with that last line and nobody caught it. Sorry mate.

[-] Huschke@lemmy.world 10 points 11 months ago

Read the rest of their posts. It doesn't seem like they're being sarcastic.

[-] TheBat@lemmy.world 8 points 11 months ago

Do you also believe the Moon is made from cheese?

Don't bother asking here, people on Lemmy blindly hate anything that has anything to do with Musk

[-] Kbobabob@lemmy.world 24 points 11 months ago

There's a whole lot to not like though. Are you saying people aren't justified?

[-] nova_ad_vitum@lemmy.ca 2 points 11 months ago

I don't see why maglev trains in a vacuum are so difficult

Then make it.
