The science of underwater tunneling

I think I managed to annoy an officer from every major branch of Boston transit on this one!

"Why It's So Hard To Dig Tunnels Underwater" ngl im going to guess that the answer is "The Water" lets see how my guess plays out.

This was an excellent video. It's incredibly interesting how techniques then really don't differ overly much to what's done today, just on a far larger scale.

Note: and still today it’s not perfect. Today, when there is heavy rain Aquarium station still leaks.

1/2 of Boston is landfill. It’s kind weird walking around my city knowing that and drive through the tunnels rather siting in traffic in the tunnels knowing how much water is above you is still scary

The graphics, the on-location footage, the production quality is unreal, easily surpassing the sort of stuff major documentary companies are putting out these days. Keep up the good work c:

I remember when the Big Dig finally was completed and Ben and Jerry's made an ice cream flavour honouring it. It was an absolute nightmare of a project. So many shortcuts were taken and so many delays and other issues. Incorrect epoxy used even lead to the death of a motorist after it opened. It was horrendous. Engineering marvel, for sure, but definitely a masterclass of how to mismanage a project. Also, just saw your pinned comment, I was going to ask how the heck you managed to set up a tripod and talk at a camera when the transit staff descended on me immediately after taking a single photo citing the potential that I was a terrorist.

Atomic Frontier just lost all my respect as a factual content creator! EVERYBODY knows emeralds can NOT be found in river biomes.

As someone who spent a large part of their childhood making piles of sand and digging tunnels through them, I appreciate this a lot.

Mate these videos are incredible! I had a look at a few others that you've done and I particularly liked the sea monster and martian cave ones. There's a pretty conspicuous mismatch between the quality of the videos you've been making and their view counts – but going by the recent uptick in your sub history, it looks like that's starting to sort itself out :) Best of luck with your future videos!

This reminded me of the subway tunnel that has been built across the Bosphorus in Istanbul (by a Japanese company I think). It sits on the ocean floor. Perhaps that would be an interesting follow up to this.

AF: "I'm on the Charles River in the City of Boston," Massachusetts Residents: "Oh I'm sorry for you"

The added problem with the Mid-Atlantic rift is that it represents the continents moving away from one another. So the distance between the continents is slowly increasing meaning the tunnel would need to grow, or be destroyed.

His presentation is like those educational programs PBS used to have long ago, like from the 80's and 70's, but were broadcasted as reruns early in the morning. Before school I used to watch them but as the years went on, they were no longer shown and removed.

Dude- Your videos are SO damn good. I'm talking about the production quality of the video, as well as the subject. SO. DAMN. GOOD.

Imagine missing an exit and now you're driving down a tunnel over to Europe.

"Looks like we're all just about done" The guy in the middle with a half-finished box

Another really interesting video! Tho, I highly doubt hyperloops will ever work properly, considering the list of their current and potential future problems is so long.

So far none of the promises of the various vacuum train companies have materialized. I don't believe that vacuum trains will be viable anytime soon, even more so if you're going to build one under water.

Absolutely epic video! Was super cool to help you film in the train, awesome work!
