This tech is far better for the environment than the air travel it would displace.
I never have understood people's fears about getting on an airplane... this though I'd be scared to death of. You have any unfortunate shift in the tectonic plates (which happens daily and unpredictably) and you could be dead in an instant.
I gather that the intent is to tether the tunnel. I've seen how cables are run in tectonic-active areas: they are provided a certain elasticity and I imagine it would be similar. Earthquakes don't move much more than a few meters at a time (for a very very large event). How would this be any different than the Chunnel? My own comment on this article: "getting to, from and through airports is very time consuming" I do…

Plus any operation at this scale will require all the security if not more of a normal one. It is just too big not to be a target for someone.

Here's how the Japanese high speed trains deal with earthquakes: They have emergency break systems (I think its small ceramic globuli or something of the sort) and a really good forewarning system. 2011-3-11 all Shinkansen were at a halt when the big one hit and noone was harmes on them. I don't see why you couldn't do the same here.
I live in NJ, about 4 miles away from my office in Manhattan and I have a 45 commute. Can anyone figure out how to solve that problem? It's a lot of fun to kill the afternoon talking about something that's never gonna happen. In the meantime, millions of people are wasting days a year crawling to and from work.
> Can anyone figure out how to solve that problem? 4 miles? Why don't you walk or cycle? I live in NH and walk to work every day. 4 miles would make a good jog/walk too if you are looking for more exercise time (depending on what you take to work with you).

Monthly bike pass is surely cheaper or comparable to whatever he is paying for parking. I solved his problem.
You are responding to me, the person whose problem you think you solved. I take a bus that costs $98/month. The ferry is over $300 for a monthly pass. If I want to take the ferry tomorrow, with my bike, for example, it'll be about $20 for a daily round trip. My best option would be to taking a folding bike so I can take a train. That would work on nice days. However, what I'm really asking for is to solve the problem…

Cycling is a solution for the millions of people who have commutes of 4 miles without rivers in between. It's a solution for most people in most other situations.

A vacuum only weighs 1.28 grams less per litre than air. Since there are 1000 litres in a cubic meter, a 3x3x3 meter cube (approximation of a cross section of a unit of the tube) would contain 27000 litres whose air would weigh 76 lbs. In other words you're talking about sinking 3 meters of tube that would weigh 76 fewer pounds than if there were air. This is probably a small effect compared to the weight of the stro…
It's not about vacuum being weightless. It's about vacuum being an active stress factor for the entire construction. It will _want_ to collapse. It's not sitting there doing nothing.

Of the $80M/mile - $70M is to buy the land and pay off objectors, $9M is security and fencing for the work site and $1M is to build the actual track. The nice thing about a transatlantic tunnel is that crustecaeans can be bought off cheaply
