Since the capacity of a Hyperloop system is close to zero (less than 1000 passengers per hour, much less than a lane of highway and two orders of magnitude less than an ordinary railroad), it doesn't really matter where you put it.
Did you mean should we compare it to airports? LAX will land 54 aircraft in the 60 minutes starting now, and I assure you that amounts to rather more than 1000 pax/hour.
LAX is 3,500 acres and only provides 1/2 the land area need for a flight. Worse you can't build anything tall near by and need all that land close to cities, making high speed trains a surprisingly good trade-off.
Of course, it's just a different form of public transportation. It needs to be competitive on a cost per passenger per hour basis in order to be viable.
The 2013 Hyperloop paper claims a capacity of 840 pax/hour under some pretty optimistic assumptions. I'm willing to grant them all these assumptions because this number is tiny and pathetic. A highway has a nominal capacity of 1800 vehicles per hour at a 2-second following distance, which works out to a capacity of at least 1800 people/hour and at most, in a dedicated bus lane, something more like 20000 per hour. Railroad capacity is much higher. Even bad railroads like UK National Rail have demonstrated over 200k pax/hour into a single station.
Some good points, but I also think that the train system is overhyped here (comparing a single hyperloop v1.0 with a single terminal with a whole train station isn't as useful as it could be.) [Aside: Also, knowing the knots Palo Alto and other cites tie themselves in to deal with the high speed lane up to San Francisco, I'm not sure that HSR there will ever be successful, no matter how much $$$ and time is spent. Drives me nuts]
I also don't know how to compare highway costs - dunno what it would cost to increase one lane between SF and LA, plus adding a lane doesn't increase capacity linearly AFAIK.
The problem with CAHSR is that they decided to go whole hog on brand new high speed rail pretty early, and that they specified the top speed and expected travel times as a matter of law.
Realistically speaking, it's a lot more cost-effective to bring the slowest sections up to good enough speeds for medium-high speed rail. Each 10MPH increase in max speeds lead to diminishing returns.
To get a better comparison, how many people fly from SF to LA every hour? That's the use case.
1 flight per hour sounds about right as a ball park estimate. A hyper loop beats that in capacity, and would likely be FASTER (due to not having to go through airport security).
A cursory look at Google Flights shows a lot more than hourly flights from SFO-LAX. That's also not including flights to other area airports like Oakland, San Jose, Ontario, John Wayne, Burbank, etc.
Looks like the eventual plan is to link the airport to a tourist spot and the city is just the first stop on the way through. Might also be cheaper/easier to do in a less populated area.
That's how most Chinese infrastructure projects start. I saw Ningbo in 1992. I look at it today and, yeah, can you say different?
I thought Three Gorges would be impossible, even for the Chinese. A few key innovations later and there it is. (Subtle innovations which, in my defense, a reasonable engineer would never have seen coming.)
If there's one thing they're good at over there, it's building infrastructure. I'll give them that.
The last time I was in ningbo was 2004. Is it really that different today?
Building a dam isn’t that hard? Definitely not impossible if you are willing to displace a few million citizens. But tunneling under granite for 30+ km? Yes, possible, but it won’t be cheap. I don’t think the Chinese would do that, it will definitely be a vacuum enclosed viaduct to match what they did with HSR.
Three Gorges is a mile and a half long almost. (maybe a tad longer.) Almost what? 6 or 7 hundreed feet tall. Ship locks and ship lifts too! For what? 10 thousand tons or so would be my guess? Not to mention entirely new ports to accommodate new heavy shipping inland. New walls and other flood control measures. And all of it designed to concert in such a manner that they never exceed the design specs of the dam.
Displacing citizens is the LEAST of the problems that project faced.
Building ANY dam is definitely not to be characterized as "not that hard". Building Three Gorges falls on the "near impossible even with backing of wealthy nation state" end of the scale.
I’ve been through the dam before, I know how large it is. The locks (multiple ohes) alone take a whole night to go through. And at the end of the day, the human cost was the greatest hurdle for the project that still isn’t completely worked out.
But I don’t see how it was extra amazing vs. the grand coullee or hoover dams built almost a century ago.
"...But I don’t see how it was extra amazing vs. the grand coullee or hoover dams built almost a century ago...."
Count the number of locks and lifts integrated with them.
Count the number of deep water ports built to concert with them.
Then you'll START to get an idea of how non-trivial Three Gorges was. It's not just a dam, though a dam even the size of Hoover or Grand Coulee would be non-trivial in themselves for us to do today. (A dam the size of Three Gorges? Not even close to being easy.) Throw in concerting projects, and to call it "not that difficult" is, frankly, laughable.
I think something similar to the original Hyperloop proposal can work, but I'm not going to actually believe it until I see at least one real world implementation.
No dude. It's super real. This partnership makes sense because the next step is a Hyper loop between China and Los Angeles. Very good ideas. Real science. You just move the 99% over INTO the 1%. Now we are all the 1%, or the 199%. I haven't done the maths.
Completely serious question given the downvotes: Is this discouraged or banned on HN?
Whenever I hit a paywall from an HN link, I immediately go to the comments to see if somebody has linked to the full article. Thought I'd help folks out since nobody had done that for this article yet, but if I'm out of line I won't do it again.
Very cool to see this technology progress. Will be interesting to track. China certainly has shown that it both can invest in and build public infrastructure at an amazing scale and pace.
It's a little concerning that this isn't really a sale - it's a joint venture. From the article:
"HyperloopTT will form a joint venture with the Tongren authorities, according to the Guizhou provincial government, though the company’s announcement didn’t say whether it would be expected to transfer technology."
Has to be taken with a bit of caution as we've seen how this worked out in high speed rail:
"China's early high-speed trains were imported or built under technology transfer agreements with foreign train-makers including Alstom, Siemens, Bombardier and Kawasaki Heavy Industries. Since the initial technological support, Chinese engineers have re-designed internal train components and built indigenous trains manufactured by the state-owned CRRC Corporation." [https://en.wikipedia.org/wiki/High-speed_rail_in_China]
You'll find that China now is battling for dominance in the global high speed rail market and the formerly leading European providers (Seimens, Altrom) and in trouble and may have to merge just to survive.
China probably sees it as being in their long-term interest to prop up American hyperloop companies so that Americans don't come to their senses and build trains. The longer we're distracted by hyperloops, on-demand taxi services, and self-driving cars the deeper our technological hole becomes.
You have to be kidding, right? How much do you think it would cost, per mile, to build roads capable of moving 100k people per hour? That's a 100-lane freeway. California High Speed Rail is being built because of all the alternatives studied it was, by a large margin, the cheapest. Freeways and airports are much more costly for the same capacity.
Well, to be fair, the estimated average annual daily traffic for the most traveled LA freeways isn't anywhere near 100K per hour, either. It's around ~400K vehicles per day, and assuming 1.5 average riders per vehicle, that's 600K people. So if 200K riders per day is the most optimistic published ridership projection for CAHSR, it's not at all a bad number. (Acela's daily ridership appears to be closer to 30K, though, so I would be really surprised if the CA system is that high.)
This is where citing studies would be helpful instead of arguing on instinct. But also remember: with cars you push a lot of the costs to riders (vehicle capex, maintenance, fuel) and there is interoperability with "last mile" infrastructure (city roads). With trains you build the entire infrastructure for the long haul, and then still end up relying on other modes of transport at the end. Imagine if in building a new freeway you also needed to buy all the cars on top of it...
In the Bay area, there's no space to expand the highways, but you can increase capacity on the rail lines. Caltrain can double capacity through electrification and level platform loading. Which one do you propose spending money on?
Given how many people ride BART, Caltrain, and VTA light rail in my area -- and how proximity to a transit station has become a major selling point for residential development, both old and new -- at least around here it seems to be working out just fine, thanks!
While I presume you're taking a dig at the high speed rail project, it's worth remembering that that's not the whole of what "train service" means. It's also worth remembering that as of yet we don't really have a baseline for how the cost of longer-run train service compares to hyperloop service; as fun as it is to blame HSR's travails solely on being a government project, the reality is that there are very, very few private projects that are conducted on such a massive scale that we can point to and say "look, that was so much more efficient." Last but not least, there are good arguments against using "cost per passenger mile" as the be-all-end-all metric for transit, which you can find pretty easily if you're so inclined.
> We can't build any public infrastructure in the US anymore.
I know it feels that way, but it's not strictly true. Here in Seattle in the last decade we've built a new floating bridge, multiple miles of underground light rail track, and nearly two miles of deep bore road tunnel.
I think there is a real problem that our new infrastructure is way too expensive and takes way too long to build, but we've demonstrated that we can definitely build new stuff.
Seattle's light rail is mediocre. I wish they had gone full in with a heavy rail and subway system instead.
They could've used that to link up Seattle, Tacoma, Redmond, Kent, Bainbridge Island, Vashon Island, and the entire Seattle area.
And to keep costs of building the infrastructure down, then they should consider outsourcing it, and hiring Chinese labor. (Apparently, the Chinese are very good at building railroads.) That way, you keep development costs down, and afterwards, the local citizens can enjoy first-world infrastructure, at low rates.
But, when infrastructure projects become billion dollar estimates, then that just kills any opportunity of it ever being developed. Simply, because it now becomes a major high-paying jobs program.
We are building a new, cool mass-transit system here, there's going to be a small-bore tunnel with electric skates between downtown Chicago and the airport.
That is just a regular type tunnel built by the Boring Company and using electric vehicles in it. Not an evacuated tunnel with very fast vehicles. Spending extra for Hyperloop speeds really only make sense for longer distances. Not sure why this Chinese project is so short unless it is just a bigger type demo for the company and China hopes to acquire the technology like it has for so many other advanced systems invented in the west.
The tunnel is cool and great. I hope we can get these tunnels all over the place. I was just saying "Were building it here" is factually wrong about the Chicago tunnel being a Hyperloop tunnel.
"Cool" and "new" usually ends up meaning "expensive" and "proprietary" later on, especially if it's not standards conforming and tries to reinvent the wheel.
BART's technology was created by aerospace engineers who wanted to reinvent the railroad and make it "better".
What this resulted in was
- a wider track gauge than any other used in the US
- bespoke rolling stock with different braking, control, coupling systems
- untested ATO that had several early failures
The first two have had lasting impacts; servicing BART equipment is very difficult because no one else has ever made traincars like that, and it makes it difficult to extend BART over existing rail tracks. The expensive of all this "cool" factor is at least a factor of two over standard rail projects, which is why eBART was built as a normal diesel rail line instead of as a BART extension.
Other examples of "cool" transit technologies that ended up aging poorly because of their rarity are monorails and maglevs. With economies of scale it's hard to beat trains, and trains already go to 220+ MPH; there are very few markets where you would need to go significantly faster via land, and where doing so would be a big advantage over air travel, as Hyperloop is proposing.
Tongren county? That is like out in the middle of nowhere (well, near fenghuang in hunan) and is only known as a tourist destination for seeing Miao (Hmong) villagers. Strange.
Backpackers should visit this place, it’s like yangshuo/Lijiang before they became saturated.
This move was very puzzling to me, in light of Trump's trade tactics. Especially, of his accusations that China "steals" American technology.
So, given this, why would any new American company, choose to enter into a 51/49 partnership with China? Where China has the majority share, and where the American company must share with their Chinese partner, all the system processes, techniques, and new technology of their product.
This is just adding fuel to the fire, and the resentment that Americans have of the Chinese people.
Here, the American company is willingly entering into such a business agreement. The Chinese side is not holding a gun to the American company's head.
For the Chinese side, they are investing a lot of money into this research project, to fund this hare-brained idea. So, there is a lot of risk on their part, that nothing will emerge from this.
The alternative, is that the American company can just choose not to do it. Don't accept the money. Go it alone. Don't enter the Chinese market. The rest of the world is a huge playground as it is.
Political theater isn't the same as business opportunity analysis. Also keep in mind that the US presidency has a limit of two terms. If Trump enters into the calculations, he doesn't enter into them permanently. Transportation systems, especially rail, are long term investments.
While I was traveling in Beijing I remember hearing stories that the Chinese hired Japanese contractors to build the rail. Had them build one track of the rail and sent them home. Then they copied their design and built the rest of the railway.

The monorail at Disneyland works great and so does the one in Seattle.
They don't need to be surrounded by a vacuum tube, which is the impractical and expensive part.

China has 16,000 miles of high-speed rail. We have essentially zero. It makes more sense to build this in China.
They already have high-speed and low-speed maglev trains.
Not unless you nix the tube and just build a reliable high speed rail system.
