The viability of Hyperloop One should not be the focus in the context of this article. That's not what this is about at all. It's that Hyperloop One needed Richard Branson on board because Elon Musk is creating his own competitor now. This is an incredibly smart move to ensure the survivability of the business from a publicity perspective. Branson has a history of doing things that people thought impossible or just a…

The viability of hyperloop is nil. It doesn't exist. It is literally physically impossible for it to be viable. I think it's on-topic whenever hyperloop is on-topic.

Okay, great. It's on topic. So what?

Why is hyperloop's viability nil and nonexistent?

Just as a thought experiment, could the promotion of these "hyperloop" projects be a clever political ploy to misdirect/divert attention and prevent a viable high speed rail network from being built? Elon's main business is electric cars and (one of) Branson's is airlines. So a reasonable competitor to both is fast and cheap(er) public transport along a major travel corridor in the USA. This means that by promoting t…

Highly unlikely.

Branson's Virgin Group owns only 20% of Virgin Atlantic (don't let yourself be mislead by the Virgin name appearing all over the place - Virgin tends to start businesses, sell all or part of them when the opportunities are right, but continue to lease the name out to the buyers; the Virgin brand appears on dozens of companies with little to no Virgin Group ownership).

In 2016, Virgin Atlantic's revenue was less than 3bn GBP, with Virgin Group's "share" of that, just 600 million GBP (yes, I know it doesn't make sense to count it that directly; if looking at operating income instead, Virgin Atlantic's operating income in 2016 was ca. 150mn GBP), while Virgin Group's revenue was 20 billion pounds. So Branson's airline interests are relatively minor in the grand scheme of things.

And Virgin Atlantic would not face much competition from high speed rail (the clue is in the name - Virgin Atlantic might in fact very well benefit from a high speed rail network if it meant the ability to offer customers faster/easier access to more of the US with fewer US destinations which would make it easier for them to compete with airlines with more comprehensive route networks).

Virgin Group also wholly owns a UK train operator - if they saw "regular" high speed rail as a good business opportunity in the US, odds are higher they'd invest in it than try to stop it.

Something I wrote a while ago.... w/ back of the napkin calculations....... Why I wouldn’t invest a money into Hyperloop - Stabilizing a single fault line risk pylon is more than $250K. - How many million are needed for vacuum pumps to evacuate 100+ million cubic feet of of pipe to 100 Pa? - Hot air discharge needs to go somewhere. For every 1 bar pressure, you need ~200 to ~400 cubic meters of volume which is larger…

When Musk first said that an LA SF Hyperloop could be built for 1/8th the cost of the equivalent HSR, I chuckled and then waited for the punchline, which still hasn’t arrived. It’s a cool idea and I do want to see more prototypes and feasibility studies, but people need to get off the hype train (no pun intended) and be realistic about the cost.

Everyone has been chuckling about electric cars and private rockets until recently, and that was by experts in the respective fields. Chuckle all you want.

It would have been politically a LOT easier of they'd built a Birmingham-Newcastle leg first

and probably better for the long term economy as well; the last thing Birmingham needs is a reason why London is a good base for doing business in Birmingham.

This is a pet peeve of mine. It hurts not just the other cities in the UK, but London as well. We don't alleviate overcrowding in London by making it easier to move to London. We alleviate overcrowding in London by making more other locations economically stronger.

That should mean strengthening a region around Birmingham, faster links connecting the Leeds - Sheffield - Manchester triangle + tack on Liverpool, and a wide orbital around London improving connections between the towns around London that now are reduced to feeder/sleeper towns. There are towns around London that has decent direct rail tracks, but where the fastest rail route is a 2x-3x longer journey in to a London terminal and back out again. Actually run direct trains, and you suddenly have new viable commuter regions that bypass the centre.

Only after that should we think about making the links between these centres faster.

The problem of course is that many of these will need to be run at substantial losses for years before enough companies etc. will move/get established to change transport patterns, and it's so much easier to justify building more expensive routes where there is existing overcrowding.

Never mind that doing so just attracts more people.

> Elon Musk just waltzed into the high speed rail debate and Dunning-Krugered some crazy scheme I think it's incredibly important to segregate Musk's work, i.e. SpaceX and Tesla, from his proposals, e.g. the Hyperloop, modular infrastructure and other things.

Nah, the Dunning-Kruger thing applies equally well to Tesla and SpaceX. He had no experience in either field before starting those companies. It's just that he has, in spite of all probability, succeeded and so you see them in a different light.

Didn't he actually design the first rocket himself? He's quite smart. I don't think "industry experience" counts for much. By the way you're using "Dunning-Kruger," it's unclear that you actually know what it means...

I think GP could have a point with Dunning-Kruger applying to EM. Here's the main difference IMO: By far most people who experience the Dunning-Kruger effect have no way of self correcting, i.e. they don't recognise when they're wrong or they do when it's too late or they keep on their path nevertheless because of the sunken cost fallacy or vanity. EM on the other hand has proven to be very good at admitting and correcting his mistakes. That filter effect combined with simple uniform-density-spherical-cow type modelling for his initial guesses combined with some of the best computer simulation experts in the world seems to be enough to have catapulted his endeavours to orbit and back - both figuratively and literally.

In the near age of driverless cars I think this might be its biggest demise. If cars are automated people wouldn't need a train. It will be cheaper and less confining to a schedule and to a destination. I think air travel for short to medium flights will fall off. By the time I leave my house and get to someplace that is 8 hours by car it would take 5 hours to check in and check out and you still need to rent a car.

Autonomous vehicles do not obviate grade-separated transit options. Even if we imagine a road network populated only by highly efficient and inter-connected autonomous vehicles, the increased capacity allowed in such a situation will only create more demand, which will scale up traffic problems. Now, other than traffic, I agree. When deciding whether to drive somewhere or take the train, my second factor is whether o…

The real benefit, in my opinion, from autonomous vehicles is that they remove a major barrier for a lot of people to not owning one. By taking drivers out of the equation, you can cut cost or increase vehicle availability or both to the extent that being able to get vehicles urgently, or cheaper, depending on need, can give most people in densely populated areas an experience close to as good as owning a car. Better if multiple people need to go different places.

And while you're right that this will probably drive up demand, it achieves something else too: Availability of extensive route information. Now imagine a shared system for such cars to negotiate routing, and such cars can know which routes will be less congested, and can know which cares it is most effective to re-route because of where they're going.

E.g. there's a chokehold near me for Southbound traffic that it's tremendously beneficial to bypass if you're heading South-East, because you can take back-roads with lower speed limits but that are shorter, and that will end up being much faster when the chokehold is congested. Which it "always" is between certain hours. But if you're going South West, it's better to suffer through it.

With vehicles able to negotiate route information, vehicles going South East could be automatically re-routed when there's congestion, resulting in average speed improving for everyone.

In fact, you could even imagine a system where cars autonomously negotiate a fee for other cars to let it get in front (so you could e.g. pay a 30% premium for urgent trips and have the car company spend, say 25% to buy its way in front of others on congested routes).

This may not entirely solve the problem, but it can make congestion more about total throughput than maximizing throughput on a small number of routes.

End-to-end route information also opens the door for services to mediate multi-step routes with e.g. cars feeding public transport much more efficiently (e.g. in my case I live almost exactly halfway between two major rail stations, with two more small ones not much further away. I almost always opt for the largest of the four because it's at a central junction that gives me the best option for almost every destination so I rarely need to think about it, and it also means I know exactly how long it takes me to get there.

But if I can tell an app where I want to go, and get told to either go to the bus stop or wait for a car, get taken to whichever station is the best option and told which track/train to take, and get picked up by a car on the other end, there might be substantial time savings and often a better shot at a seat. The only thing stopping me from "shopping around" like that today is that it's extremely inconvenient.

Again combine that with pervasive end-to-end route information, and you can make it even better by ensuring not too many people get routed onto each train if two options are relatively equal and one is less loaded.

Okay, we'll bookmark this for the future. Amtrak estimated a HSR/"bullet train" from D.C. to Boston would cost ~$151 billion. Since LA to SF will only be two stops, and we can assume Amtrak estimated at least 4 (Philly and NYC) let's bring the number down closer to $100 billion to make it even. Do we think the Hyperloop costs are more or less than that? 1/8 of a theoretical $100b is $12.5b -- is $12.5billion for Hype…

You're starting with the wrong number. The $151B number is Amtrak's estimated cost for it's "shoot for the stars" plan. It…

Meanwhile Switzerland, one of the top most expensive countries in the world, has tunnelled at the base below the alps (one of the most difficult terrains to tunnel due to vertical sediment layers) for ~20B. Workers died on that project too, but that risk is simply being managed rather than grinding everything to a halt.

I'd argue it's absolutely possible to improve the cost on American public transit infrastructure by one to two orders of magnitude if you can simply get a way around government capture.

Assuming your are correct and Branson knows it because he hired good engineering advisers. Why would Branson get involved ? - It is a cool project he wants to be part of and he is willing to pay to see. (I would probably do that) - The benefit is not to reach the goal but all the technology that will be invented trying to reach the goal.

Branson's business model is selling the right to use the Virgin brand to other companies. The article doesn't say he made an investment. It is rather more likely that they paid him.

Is that actually the case? My impression is that the vast majority of companies bearing the Virgin brand was either started by Virgin Group, bought by them, or has seen a significant investment. Many have since been divested again, and continued to license the brand, but I've not heard about any cases where they just licensed the brand without other financial involvement. Maybe I've just not paid attention?

Go here and scroll down to "Select historical production vehicles" - https://en.wikipedia.org/wiki/History_of_the_electric_vehicl...

I grew up in the 70s and saw production electric vehicles that are not on this list. People have been chuckling for a long time and for good reason. It's not that electric vehicles won't eventually be successful -- they must. It's that the time from, "Hey, an electric vehicle would be a good idea" to "Hey, we've figured out all the engineering challenges to make this viable" is longer than the lifetime of most of the companies that entered the fray.

Look at the list of vehicles from before 1990. That's the "getting to the market first" list. All gone. Then look at the list from 1990 to 2010. How many of those will be major players in the electric vehicle market? My point is that I'm relatively old for someone on HN and there have been production electric vehicles since well before I was born. They only started to be viable in the last few years -- and even then, we probably need a few more breakthroughs in battery technology before the market settles out.

Long distance, super fast trains in tunnels? https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen I saw the tunnel the other day. I was surprised that practically the whole damn length of the maglev tracks will be in a tunnel, but it makes total sense. That's been under construction for 10 years. They are optimistically expecting to make a profit in 2026 when "costs stabilise".

Will long distance, high speed trains in low pressure tunnels be successful? I have no doubt. Will Hyperloop One be successful? Umm... frozen balls of ice remaining intact in a very hot place probably have a better chance, but I won't say they will definitely fail. If they can secure something like a trillion dollars and invest it wisely over the next 30-40 years, then their chances will improve significantly.
