New York to London in Under an Hour

Unfortunately, no matter how fast the transport,
it will still take you more than an hour to clear 'security`,
and that's after you deal with the traffic getting to the terminal.

"Oh tempora, Oh mores."

that's man invented cellphones

Many of the comments are on passenger travel but those in the business of transport know that real money is in freight and there are many who would pay large sums for freight this quick.

I'd like to see details of the expansion/deflection joints at the mid-Atlantic rift.

Hmmm, and Bostons big dig was projected to cost $4 billion and ended up costing $15 billion. Plus it is a leaking falling apart death trap that is costs over a billion per yr to maintain due to faulty construction. I hope the transatlantic tunnel doesn't use the same union labor.

I wonder if the $12 trillion includes the inflation of raw goods due to the increased demand in materials. If something like this was to kick off, it might be time to change careers!

They really need to build one in small scale first! A floating underwater 3100 mile tube in perfect vacuum? I think a 60 mile tube into space might be a more realistic starting point.

If I did the math right, assuming you could attain 10,000 passenger round trips per day (5000 people per day each way, 10 vehicle trips per day each way (20 round trips), @ 500 person vehicle capacity), for 365 days a year, at $10,000 (ouch!) per person per round trip … it would still take 329 years to pay off the estimated $12 Trillion dollar cost! Not counting inflation or maintenance costs, of course.

What if every man, woman, and child on the planet took the trip at least once? $12T / 6.5B people = $1850/person

What if we just bought every man, woman, and child on the planet a cell phone? 6.5B * $50 = a mere $325B (that's 0.3 Trillion $)

What if we bought a bunch of supersonic airplanes at, say, $100M each? We could buy 1200 new planes each year, for 100 years, for $12T!

Project is DOA. The concorde was a good idea, but not enough riders to pay the cost. I would worry about the extreme pressures on the structure at mid atlantic depths. James

Videoconferencing was supposed to make this sort of thing unneccessary.

Then do it!

Why waste any time Travelling?
