The Elon Musk hyped Hyperloop One has gone out of business. Who could have predicted it?

When Musk hyped Hyperloop One? Musk published Hyperloop design idea, and later has build a test tube at SpaceX premises that was used for student competitions. That's about it. Hyperloop One has nothing to do with Musk and I couldn't find a single example of him endorsing it.

I said exactly that in the video.
I mention Elon for the keyword SEO

After the failure of Virgin Orbit, the company seems to be on a downer.

Vacuuming passengers is not such a new idea...

Interesting.   What say we put a fan at either end of the tunnel, one sucking and one blowing, AND, add solar panels onto the roof of the tunnel that will power the fans.

That has got to be worth $100 million in government funding surely?

[nonlinearschool]

 :popcorn:Yeah scam city, however, if just freight shots 100m 200m long. using whatever..say, mag-lev, and a sealed tunnel to prevent theft.There would be huge profits. The real difficulty around the world is finding a place to lay any length of rail today.  Too much land owned, too much NIMBY, too much incredible costs for eminent domain.

The US cannot even get high speed trains...not even over 100MPH simple because of the above reasons.  California might happen by, what?< 2050? 2150? LOL. New York to Washington DC, almost 100mph, standard trains. Pittsburgh to Phily is is? initially claimed to do Chicago to Phily... never happened.

In Africa? in a dictatorship?  Yes, China. It's simply building any railway of length.

Imagine a puff firing freight from SF-Bat Area to LA. with mag-lev support...whatever, remove drivers, engineer. move at as little 100mph. reduce cost from 18 wheeler diesel trucks or diesel electric trains.  Hugs profit. and here's the best part HD steel tubes, to prevent hi jacking!! LOL

Lived in S Colo. Know Pueblo..considered the US capital of steel making. Property cheap and empty.  Owned some land there once. held for twenty years. zero increase until early 2000's when plans to build a couple of super dams to feed all of SE Colorado. Sold, Native American's  blocked any dam making, and real estate dropped to 1980 value.

Anyone think we can get a simple HS train built? in USA, in Europe outside of France? UK continent, or Ireland? Korea?  Japan is building another line.  Maybe an Aussie single shot from eastern seaboard to Perth...Sadly, that would really screw any who remain in between.

In Germany we have a 24 meter long test track.

Europe’s first certified full-scale Hyperloop test track is now ready for test operations, marking a significant milestone in sustainable and ultra-fast transportation. The 24-metre-long track was developed by the Technical University of Munich (TUM) Hyperloop research group. The first successful test run with a passenger pod in vacuum conditions took place on the 10th of July 2023.

Circulating the cash in the economy is somewhat useful. It's when the music stops the problems start.

[djsb]

There is an argument that there is value in the development work carried out in trying to solve this particular problem. Work involving students in universities get the chance to work on systems design and the hardware and software involved. The journey may be better than the destination.

[RoGeorge]

Yes, but the same benefits of gaining experience + serendipitous discoveries will also happen during a journey to a fruitful destination.

Then too bad, you don't get to find out updates like that.
Where else am I supposed to put it? On the forum? Where? Youtube Community Tab where everyone would complain they get notified of every post?
X/Twitter is the social media platform of choice, everything else sucks. If you want to follow me, I post there multiple times daily. If not that's fine, but don't complain that you miss stuff.
I also post my videos natively on there as well, so you don't have to leave the platform to watch my content, comment, and follow my every update and thought.

See my Part 2 TUM Hyperloop video for an example of this. Over 80 university people working on this project after a grant from the Bavarian state government.
But make no mistake, the grant wasn't so that engineering students could get to work on a "real word" design, they had more people employed in the strategy and marketing department than on the project and safety teams.

Also, I found this document on an anlysis of the commercial prospects.

Nevomo is a company from Poland, which “introduces hyperloop in steps”: first by retrofitting a maglev rail on top of existing traditional railway, then surrounding that with tubes, then making it the “true hyperloop”. Obviously you can’t charge anybody with fraud, if they only took money for the first two parts. I’m quite sure they will not fail in putting tubes around tracks.

Meanwhile Poland already has 290 km/h trains, both trains and rails certified for 250 km/h, deployed and getting you in 2.5 hours across half of the country. Apparently somebody has to tell these traditional rail engineers, that air drag is a huge problem.

It's like planes, you eventually reach a design optimum in terms of speed, complexity, safety, cost etc.
It's why Hyperloop will never be a thing, and Starship point to point will never be a thing.

250km/h is not that fast actually. Slower than Shinkansen and much slower than Maglev in China. Hyperloop as of "Hyperloop Alpha" paper from Elon targeted 1220 kph. You say half of Poland in 2.5 hours, but it's a relatively small distance.

Sounds absolutely ridiculous.

Meanwhile the Dutch are still chugging along...
IMHO you shouldn't see hyperloop as an alternative for trains as these are typically for short distances but for an alternative of airplanes. A crapload of stuff is being transported by airplanes which are relatively infrequent, prone to weather conditions and not very fuel efficient. Now ofcourse the question is whether transporting goods through what basically is a pipeline, is cheaper compared to an airplane but then again, oil and gas pipelines spanning thousends of kilometers do exist and are commercially viable.

Part 2: TUM Hyperloop

Two dudes were in the pod but three dudes came out of the tube. Where was the third dude hiding in the tube at 10 mBar pressure? 

[HighVoltage]

10 mbar is a pretty good vacuum for such a large tube!

Everyone that has worked with vacuum knows, what a tremendous amount of pumps is needed to empty only 1 m^3 to 10 mbar.
It would have taken a very long time to bring this 24m long tube down to 10 mbar vacuum.
Or they have vacuum pumps that I am not aware of.

[RoGeorge]

My first question would be how do they cool the train without air?

[Barny]

The most important question:
Why that big point of airodynamic in vakuum?

The goverment of bavaria is dreaming of theire own space program.
(Bavaria One)
And of course "flying Taxis"

Twitter/X is demonstrably better in almost every regard since Musk took over.

[Barny]

I don't know if you have another Twitter then I have over here.
But Twitter is flooded with spam bots & nazis over here.

I am curious what's happening with the EU-lawsuite about false information ends.
And that Elon refuses to remove hate speach and the like will be much drama in near future too.

[wraper]

Call a Nazi anyone you don't like. People like you made this word absolutely meaningless. As of bots, even before Elon Twitter was full of bots, and this problem is not Twitter exclusive.

I am curious what's happening with the EU-lawsuite about false information ends.

Fact check: Opening investigation is not a lawsuit. You just posted false information. Thus shall be banned, I guess. It's a slippery slope towards ministry of truth and dictatorship. Also I've seen a good argument this EU bullshit being in violation of UN Human Rights article 19. https://www.un.org/en/about-us/universal-declaration-of-human-rights#:~:text=Article%2019,media%20and%20regardless%20of%20frontiers.

Article 19
Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.

And that Elon refuses to remove hate speach and the like will be much drama in near future too.

Hate speech = everything that goes against your beliefs.

So, you are the one calling names here, and you think he's the asshole?
You jump to insults for what?  Because of a different opinion than yours?

Your behavior is absurd.  You have been brainwashed.  Mind conditioned to become violent.  And you don't seem to be aware of that, not even a bit.

Twitter now has:
- Monestisation for creators
- Subscriptions feature
- Community Notes (arguably the greatest feature in the history of social media)
- No political banning and influence/outright control and hence way greater free speech
- No more child porn (can't verify that myself obviously, but that's the claim, musk fixed it in a day)
- Communities feature
- No more Blue Tick apartheid system
- Two factor authentication
- Way more transparency in how it works

And the list goes.
There was more innovation in 6 months of Musk taking over than in the entire lifetime of the old Twitter.
And I'm an "arsehole" for thinkng these things made an improvement?

[AVGresponding]

Watching this interview of Musk, I'm not clear how anyone can not realise the guy is a fuckwit, and that X/twitter, whatever you want to call it, is about to go under because Musk likes to posture and insult people.

[wraper]

IMHO it's what should have been said a long time ago but nobody had a pair to do so. Advertisers ganging up in concerted way to regulate speech is plain wrong. Their job is to advertise their products and stay out of the platform policies and especially politics, not the other way around.  Not the first time it happened either, remember Youtube adpocalypse that made it bend over and change for the worse?
Here is a 7 year old Reddit comment that summed it up pretty well:

My issue with this whole thing is that Ads in the online space are not targeted to content as much as users. With TV, you can only point at a large group based on past information to target advertising. So the show and the Ad content end up living close together as the network sells content.
On youtube though, the Advertising is, in theory, targeted to the user, based on all the rest of the info that Google already has, so really if everything is working, you should be shown ads that are more relevant to you as a user, not the video as a content type.
If you look at it that way, it seems that companies that are complaining are really whining that their ads are being shown to appropriate customers who ALSO are watching questionable content.

[EEVblog]

Watching this interview of Musk, I'm not clear how anyone can not realise the guy is a fuckwit, and that X/twitter, whatever you want to call it, is about to go under because Musk likes to posture and insult people.

I already won a $100 bet from Chris Gammell who bet that Twitter would go under or collapse.
I'll make that bet again.

In the end Twitter et al are about making money from advertisements. If people think there is something like free speech or uncolored information sharing going on, they are deeply mistaken. Personally I don't care about twitter (and similar) at all. It is just like watching raw sewage flowing into the ocean. I rather get my information from more balanced sources like a good newspaper.

You are right. Its all about advertising. This is why we need to take note of adverts, and refuse to buy anything from an advertiser acting politically. Only buy from people who focus solely on the goods and services you want. That's how you will get the good stuff.

No due respect needed, I don't care whether or not anyone choses to follow me on Twitter or not, entirely your choice for whatever reason you choose. I'm just pointing out it's the only place that I do updates like that. Some Youtubers like Louis Rossmann and Fran do updates on the Community tab of Youtube, but I got too many complaints that they got alerted in the same way as for a video, and that sucked for them.

I get that Dave’s response was a bit harsh and could be read as “either do as I want or get lost”, if no further details were provided. But, when you answered, these were already present. So, trying to approach this constructively, what is the goal of your post and where is the problem, exactly?

I can imagine four cases. Correct me, if I missed something.

Case I: you’re already in Alphabet’s inventory. If yes, what’s the problem of being in X’s? Just waive your rights once more.

Case II: you avoid being in Alphabet’s inventory by, speaking euphemistically, using alternative access routes. Then… do the same for X?

Case III: nobody’s perfect and you happened to already be in Alphabet’s inventory, but wish to still limit the problem in general. The solution seems the same as in case II.

Case IV: your worry is the mere concept of the communication method promoted by X and you wish to avoid this. Right, that makes sense. But how would Dave post that kind of information, so it was noticed and wouldn’t require him to go and manually type things on every platform EEVblog is present at? Be reasonable, he is a human too. And don’t point to the hypothetical use of a program, that disperses messages to multiple platforms, unless you can point to one that can be trusted, works on all gear Dave uses, and can be setup easily by a person with no relevant skills.

I suppose the only thing I could complain about here, is that Dave could skip the “if you follow me on Twitter you'd know.”

It’s also worth noting, that there is an official blog entry, which also contains a direct download link. And Dave is posting to platforms other than YouTube. None of these were affected, if I understand correctly.

The problem is the same one that plauges every Youtuber/creator, everyone wants something different, EVERYONE.
Not only in type and style of content, but also in this case, updates.
Some want updates and my every throught on Youtube Communities, some hate it and just want me to STFU and make videos, some don't care.
Repeat the above sentence for every other platform I'm on: website, forum, Twitter, Facebook, Odysee, Rumble etc

The best any creator can do is do what they enjoy doing, and how they enjoy doing it, and people can either follow along, or not.

Hey, allow me to explain -

-I occasionally enjoy your videos, and I appreciate the forum and the body of knowledge it holds, by the contribution of the members.
I'm drawn to it often.

But the thought of interaction on popular social media in general repulses me. I'm not much of a follower, so I don't see the draw of Twitter/X (I'm also not of Facebook, and I've never even heard of Odysee or Rumble).

You had (helpfully) mentioned where else we could find your font of enthusiasm for science & electronics, and I (maybe mistakenly?) thought it was a safe place to voice my opinion, and maybe a few others might share that opinion.
-now I know better.

I didn't mean by my reaction that I have any expectations from you whatsoever!
I really DO understand that you get more eyeballs & therefore revenue if you post to more platforms - and I genuinely support your decision to do that.
And I can appreciate you posting where else we can all find you- honestly.

-my post was never meant as an argument, and I apologize if it came across that way.

[EEVblog]

I didn't mean by my reaction that I have any expectations from you whatsoever!
I really DO understand that you get more eyeballs & therefore revenue if you post to more platforms - and I genuinely support your decision to do that.

I earn practially nothing from Twitter. If anything I lose money by spreading my content around different platforms.
I use it because I have been using it for 14years and I like it, and because I want to support the only free speech platform left.

[EEVblog]

I suppose the only thing I could complain about here, is that Dave could skip the “if you follow me on Twitter you'd know.”

What's wrong with pointing out that I have mentioned something on Twitter before? Perhaps it will encourage a few people to follow me thier who didn't know I had a twitter account?
Or is it "the tone"?

It’s also worth noting, that there is an official blog entry, which also contains a direct download link. And Dave is posting to platforms other than YouTube. None of these were affected, if I understand correctly.

Correct. I have been posting all my videos on my blog webiste since day one. And every video is also directly hosted on my own website in 720p format.

Like I asked before, tell me where you want me to post my updates. "Not at all" is an acceptable answer, but don't complain when I do post somewhere where other people want me to post.

[golden_labels]

Yes, the tone. Whatever your intention might have been, it could be read as putting blame on the recipient.

Hi,
I just want to report something :

Hyperloop TT, after tricking and draining French subventions, is now going to Italy to do the same.

This article is in French but I'm sure you can use a translation tool or find info in other languages : https://www.bfmtv.com/economie/entreprises/transports/apres-son-fiasco-hyperloop-quitte-definitivement-toulouse-et-rebondit-en-italie_AV-202402270547.html

One quote translated : "[HTT] is currently dismantling the infrastructure planned for testing this “train of the future” to move it to Italy."
The correct word would have been dismembered... (it has been literally cut in pieces with oxyacetylene).

Here is the new (fairly recent) promotion video  :
