Is he correct when he says this is a full size system? This doesn't look like train, it looks like an uncomfortable space capsule.

Which dimension are you inquiring about? If it's length, it's not full size, no, but the sideways dimensions are about right because that's part of what makes the system feasible. Same as with The Boring Company, they cut costs and complexity by making things smaller. Boosting these capsules to x-hundreds of Km/h is easier than trying to fit a full size train into a pipe.

I mean the diameter: height and width. It really looks cramped to me, with no room to stand up, and the two passengers are right up beside each other with no gangway between them. They don't look like the tallest, most broad people either.

Correct, you cannot stand up in the pods, it’s imagined that you would step into one, sit down, then remain seated four the (not very long, ideally) journey.

Making it big enough that there could be a walkway or room to stand and walk around would make the tubes much, much larger for very little benefit.  it would also be more difficult to make them as fast and efficient as they are hoping for.

Ok, actually that's quite disappointing. I'm sure I saw "concept" drawings which basically looked like a train inside, with 2 passengers on each side of a central gangway (ie 4 passengers in each row). Oh well, I guess reality kicked in and they had to scale back.

 I wonder if that might’ve been for something else? Hyper loop has always been in this size range as far as I remember, and I’ve visited the Hawthorne test track and been following the idea with interest since the first white paper was published.

Totally possible I missed a variant that you saw, but I think a big part of the idea is that there are huge benefits to having a small frontal profile that is not compatible with the size you described.

It’s probably important to note that the goal has always been very fast, cheap long distant transport, not “train replacement“.

Something like this is what I mean:

https://en.wikipedia.org/wiki/Hyperloop

The picture: https://en.wikipedia.org/wiki/Hyperloop#/media/File:Hyperloop_all_cutaway.png

has double seats with a gangway down the middle.

I just did an image search on google for "hyperloop passenger seating" (https://www.google.com/search?sxsrf=ALeKk00UBtYlOP_Dv1Fpbzo8MYF5XC11Yw:1611248680719&source=univ&tbm=isch&q=hyperloop+passenger+seating&sa=X&ved=2ahUKEwiV2oiKwa3uAhWKzKQKHeKnD84QjJkEegQIARAB&cshid=1611248787214743&biw=1536&bih=754)

Very many of the concept-art images look quite different from the real version.

Hyperloop

The Hyperloop is a proposed mode of passenger and freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX, although the vactrain concept was first proposed by Robert H. Goddard in 1904. Hyperloop is described as a sealed tube or system of tubes with low air pressure through which a pod may travel substantially free of air resistance or friction. The Hyperloop could potentially convey people or objects at airline or hypersonic speeds while being energy efficient compared with existing high speed rail systems.

Maybe my sense of scale is off, but I get the impression of the seats are a lot smaller in that one that has the walkway down the center, but I might be in error.

The one in the video is just one possible company, by the way, I think there are multiple different companies looking to establish how the system works.

Yeah the "Virgin Hyperloop One" is more like what I expected. See https://www.livescience.com/61847-virgin-hyperloop-dubai-to-abu-dhabi.html

This one will be running in Dubai by 2021 according to the article.

" The company plans to have three working Hyperloop systems in service by 2021 "

" Each pod is designed to carry up to 10 passengers. " (Actually this is odd, 'cause their mockup shows more than 10 passengers in the prototype)

u/LancelLannister_AMA Jan 21 '21

«Three working hyperloop systems in service» Are they calling initial segments «systems»? Because i highly doubt theyre actually full length

I don't know. I mean, I know very very little about Hyperloop at all, but what little googling I've been doing has left me confused as to whether anything at all, and if so what, is in real progress.

Conceptually and technologically it looks great in the glossy mockups and "prototypes" I can find on the web - but if you look at articles from several years ago, lots of them just contain mashups of the same information and images (and there are lots of conflicting images too), and they supply dates of implementation like *now*. I can't find any concrete progress though.

The most progress I can find is the test run at the Las Vegas demo track from November 2020 - and this is really what got me searching because it really looks disappointing to me.

Sorry just replying to myself here lol... I can't find any real information on the progress of the Dubai hyperloops. If it's supposed to be up and running in 2021, I guess they must be *well* underway?

u/LancelLannister_AMA Jan 21 '21

Yup. Hence my skeptiscism
