Since this is a thread about Elon Musk, transportation infrastructure, public transportation, and urban design, and because HN has a sort of affinity for the Robert Moses story (The Power Broker was one of 'aaronsw's favorite books), this seems like a particularly on-point Twitter thread to read after the video:

You might not agree with all/any of it but I think it's hard to say this isn't thought-provoking.

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.

This is not boring at all. Finally someone found a way to monetize tunnels.

Someone is pointing to problems that seem obvious, I can see a lot too, but they've solved monetization.

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…

>But there's no engineering reason why a hole in the ground can't happen.

Well, unless you count damage to whatever happens to be in the way of the tunnel and buildings on top of tunnel. This might be more of a problem in Europe than in the U.S. 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…

We'll have to look seriously at living underground on mars. It won't protect us from solar rays on the surface. One of the cheaper ways to protect yourself is to put a layer of rock inbetween you and the sun.

The costs of tunneling are like FAR more expensive than most think. Breaking, excavating, and supporting rock is slow, time and cost heavy, and precarious work. While this is an interesting concept, unless there are serious advances in rock boring techniques (personal opinion: there are none coming) this will never approach fruition. I would suggest anyone interested in further research look into the "Big Dig" of Bos…

AFAIK, in many major cities, a major part of the cost of tunnelling is the fact we simply don't know where hundred-year old utilities are.

And, hell, the fact that many cities aren't built on rock (e.g., London, Berlin, Moscow), so even if you can bore through solid rock you're probably not actually that well off: can you also bore through clay and gravel?

This is to subways like hyperloop is to high-speed rail. A stupid overelaboration of an existing, proven idea.

Hyperloop is a 'stupid overelaboration of an existing, proven idea'? I was not aware we had so many proven 600mph high speed rails.

That's the entire point of The Boring Company. It's way more expensive than anyone expects. That's the problem they are trying to solve. The entire goal is "serious advances in rock boring techniques". That may be a lofty goal, but at least the message I got is that it is the one they want to reach.

It seems to me that there may be room for disruption. Currently every TBM (tunnel boring machine) is completely bespoke and is used for exactly one project and is then dismantled/recycled. They cost hundreds of millions of dollars each. I imagine there are relatively few manufacturers out there building TBMs.

Actually in some ways it bears a resemblance to the spaceflight industry (expensive, custom-made, few players). Coincidence?

Seattle's Bigger Dig is also worth studying: https://en.wikipedia.org/wiki/Alaskan_Way_Viaduct_replacemen... Sending rockets to another solar system would be cheaper than the tunnels depicted in this video. I'm not even kidding. Where is all that material going to go? There's so many tunnels there you could build a small mountain with it. Maybe he can team up with some sea-steading outfit and build a small continent…

Loose dirt off of the coast of SF? That doesn't work so well in an earthquake. Lookup "liquefaction".

Toronto really needs this. We have a raised express way that's right in front of our harbourfront and it makes the whole area noisy and ugly, blocking what should be a great view towards (great) Lake Ontario. Most importantly it takes up a ton of very valuable real estate. A huge amount of condo development has been done right next to it and having lived in one the noise is a real problem. Living on the south-end of…

Toronto is one of the most dysfunctional cities in NA. They can't even add a new subway line or additional stops. They have no problem closing down every major high way in the City for a marathon every weekend during the summer or the Molson Indy causing massive traffic issues. The City Council is inept so good luck hoping they could ever have the insight to agree to something like this. , so I really doubt they will…

Toronto has enough space that LRT makes way more sense financially than subways but Ford ruined LRT in the minds of almost everyone.

Even GO could cut down a lot of traffic if they'd just add more parking lots on the edge of the city and make it all day two way. When I use to live north of the city there were 3 trains into Toronto in the morning on the Stouffville line and 3 trains back at the end of the day and if your schedule didn't fit them exactly then you had to drive to Finch and hope for a parking spot or drive in.
