When I heard about this previously I wondered if it's a way of developing tunnel boring technology and expertise that would ultimately be useful on Mars. Underground tunnels and spaces are likely to be useful for a Mars colony and Musk is trying to figure out a way to get someone to fund it here first.

This is very, very wasteful compared to actual mass transit. A subway network is much more effective at delivering people. If he's looking for mega-good, Musk would do significantly better to drop a full subway network. edit: tunnelling is a broadly solved problem. It's difficult, expensive, slow, etc. But there's no engineering reason why a hole in the ground can't happen. Musk might be able to drive some significan…

The video shows some sort of shuttle using the track. Those could be small busses or even public transport.

In effect, this is a subway system. It's an underground rail system. The major difference is that you have a mixture of public and private passenger vehicles and smaller vehicles.

I think he's gone one step too far on this project. Concrete is something that's necessarily expensive to produce, there's inescapable costs in the production cycle, so while he could probably make it 80% cheaper, he can't make it 99.9% cheaper.

I agree that video goes WAY too far. The tunnels in that video are absurd. I give way better odds of him actually sending people to Mars than building that absurd tunnel system. But he might succeed at something somewhere in between the tunnel he is boring in his parking lot and the video. Context: I lived in Boston during much of the Big Dig. Large tunnel projects scare the heck out of me as a tax payer.

If he wants to get into the tunnelling business and start bidding on these "big dig" projects in various cities, I think he'll find some success. His engineering aptitude, his ability to think around problems, that's gotten him to where he is today.

If he retreats from this and builds some kind of pneumatic tube system to transport goods, people, or whatever, he still might have a chance of a win. Those systems have been proposed, and in some cases actually built, and in many cases they've been great ideas.

If he stubbornly insists on pursuing this batshit insane system of tubes he will fail, and he'll fail hard. There is not enough concrete in the world to make that many tunnels.

Well, which is it? Solved, or difficult/expensive/slow?

Anyone know what it's costing Tokyo Mwtro to keep digging tunnels at very large depths? They have great coverage yet they're still digging new lines.

The issue with Tokyo is that the density supports metro expansions.

Per distance costs should be theoretically comparable? (Regulation costs and labor coming to mind as drivers of cost differences)

Not only the drilling, but the shoring up and walling of the tunnel. Also, people tend to be opposed to "move fast and break things" if they're likely to get buried under them.

Until you remove the "they" by fully automating the system.

People also tend to object to "move fast and break things" when they, and their very expensive buildings, are on top of said things and get broken as a result.

I have to give Elon Musk credit - the average person would be hard-pressed to come up with even a single laughably impractical mode of transportation, but he's got two.

Hyperloop looks insanely good in comparison. Like ideally it's just an upgrade on trains. This is some bizarre daydream.

On the other hand, investments in better boring technology produces a lot of valuable real world construction industry IP for pretty conventionally dull projects that happen to involve underground travel (as well as potentially being useful for his Mars and megacity dreams). Millions of people travel on underground railways and drive through hillsides every day. Whereas most innovations necessary to develop relatively-less-unsafe means of propel people at high speed through long distance above-ground vacuum tubes are kind of predicated on the assumption that people might actually travel in a way similar to his concept sketch.

Ignoring the marketing video, it's easy to see why he's potentially going to spend more engineer time and money on the boring technology and schemes for building big swooping curvy tunnels through prime metropolitan real estate whilst being happy to "open-source" the idea of firing people through metal vacuum tubes for others to work on.

Telecommuting is a lot cheaper and easier. Also, what is the point of those rails? Seems like self-driving cars would be much easier and require a lot less. I think the robotic conveyer belt style design like seen in movies like iRobot would be cheaper and more convenient. Plus, having it so people don't walk to their cars means you don't have to worry about theft in parking garages as much either.

>Also, what is the point of those rails? Seems like self-driving cars would be much easier and require a lot less.

That was my first reaction as well. I think it might have to do with there being no way of expelling the exhaust gas. As long as even just 1% of the cars using the tunnel are fossil fuel powered their exhaust will poison the whole system (carbon monoxide can fuck you up at even just 50 PPM).

They could limit the tunnels to just self-driving electric cars though.

I feel like everything Elon Musk undertakes with his companies is just one huge Mars Beta Test. - SpaceX: Obvious, got to get to space somehow - Tesla: Build cars/machines to run on something that is guaranteed to exist on Mars (the sun) vs. Oil - Gigafactory: How to build batteries 101 - Solar roof: While Earths environment may not be as harsh as Mars you still learn something, and improve solar panel production in…

Nope that's the main one. You obviously haven't lived in LA :)

I am not sure the poor state of existing infrastructure precludes someone from building their own new infrastructure. Public transportation outside of the US is often run by private companies, and they make plenty of money. Even in the US, passenger rail is typically run by the government or government-like bodies, while freight rail is just private companies. I don't think there's an intrinsic reason for that, it's…

> The fact that your local politician doesn't want to allocate public funds to shoring up a collapsing bridge doesn't mean that Elon Musk can't spend his own money to build his own bridge (tunnel in this case), right? If you're advocating for a private transportation network, then I'm theoretically OK with that as long as it's not subsidized directly or indirectly by the taxpayer. No special tax loopholes or favourab…

The problem with such tunnels is that they're natural monopolies, not least because underground space in reasonable depth is finite. It's not a service you'll get competition on.
