This seems pretty similar to Musk looking at everyone throwing away rockets and deciding to do something about it, however if you look at Seattle's big dig the cost of the machine was only 80 million out of 4.2 billion. He's going to have to find significant price reductions beyond just reusing a boring machine.

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…

Maybe one day we could connect the individual pods, and even gasp route these "coupled cars" on rails above ground. I wonder if anyone has tried that yet?

That would be amazing! I wonder if car manufacturers wouldn't oppose it through some sneaky moves though...

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…

I don't expect the Gardiner will ever be buried but I really wish the vote to tear it down and widen Lakeshore had won. I've read that the backfill land that makes up that whole area south of Front street would make it a lot more expensive than normal tunneling.

I use to live at 18 Harbor about 3 stories up from it and while the drone just became white noise the motorcycles at night were awful. Though that spot also had the horns from ACC spoiling the hockey games on TV(you knew a goal was coming) and the noise from concerts was often loud enough to clearly hear the singers words. Before that I lived at 33 Bay st in the same complex and you didn't hear a thing but I was 30 stories higher.

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…

What? You could put trains on those tracks.

I think it's neat. I like London, but it'd be sweet to have my car while I was there.

Oh jeez I wish someone could just invent some kind of underground mass transportation system able to efficiently transport lots of people from place to place in built up metropolitan areas. That'd be awesome. We could call it a 'Metro' or something.

Earlier quoted context omitted.

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…

If you start the tunnel down far enough, you could be below anything that could be hit. Would that make it less expensive?

You make it sound like all that's down there is uniform layers of perfectly intact rock just waiting to be bored.

No, it's a hellacious mess of rocks of different types, of muck of all kinds, of brittle, water-filled pockets of who knows what, and every inch you dig you find out there's another problem up ahead.

In the case of Seattle they planned, they surveyed, they did test drilling, and they plotted a course that should have avoided everything, yet they still managed to slam into a steel pole that shouldn't have been there. It set their project back months, the machine was trashed and had to be dug up and fixed.

Plus, these tunnels are only part of the package. You need those surface access lifts, and those may well be the most logistically complicated of the whole system. To make this accessible you'll need hundreds of them, potentially thousands, and each one is a mega-project unto itself if you've sunk the tunnel down deep enough to avoid all those hazards you're now digging straight through.

The deeper you go, the more those lift stations cost. The shallower you go the more you'll come into conflict with infrastructure. There's no easy win here.
