"OOPS, what if the is a small problem problem while YOU are mid-way under the Atlantic..."
That was my thought. Every idea looks good as long as you don't consider what can go wrong.
It is hard to imagine anything worse than to be stuck thousands of miles away from land, under the ocean, in a vacuum tube.
A full working system up and running within a decade? Right, because the planet has infinite financial resources to fund such an adventure.
"space travel on earth" seems like an appropriate description. All the costs (and more) and all the safety risks of space travel -- just to save a few hours relative to an old-fashioned jet aircraft.
OOPS, what if the is a small problem problem while YOU are mid-way under the Atlantic...
perhaps a minor vacume leak, or a power outage at the vaccum source... or an electrial outage on the levatation system...
hum, maybe you also consider the use of a straight shot frictionless "tube flight" system that claims to get you anywhere in the world in 44 minutes ??

Polytechnic Institute plans a
$70,000 research facility, Project
Tube Flight, to study the feasibility
of high speed, aboveground
tubes for mass transportation.
The U. S. Commerce Department
granted the contract
for the work.
Why not use this within cities for high-speed package delivery...like they used to have in Paris 100 years ago? They used pneumatic pressure to zip letters along. This could be used to replace couriers, and it would be a lot safer delivering packages than trying it out on humans. It might even enable a proper e-commerce system...Imagine getting deliveries from amazon in an instant...actually wait--4000 mph is still too slow to cross the continent in less than one hour...
For people, a tube built through the oceans would be the safest solution...earthquake proof and relatively safe from human interference. It could float a few dozen metres below the surface.
This is obviously completely implausible. London's current Crossrail project is costing £1.5bn for 21km of tunnels. For a 4000 mile trans-Atlantic tunnel, that scales to £460bn ($720bn), and that doesn't even include making the tunnel vacuum sealed and the additional cost of building several kilometres under the sea. Adding the fact that maglev track is $40m/km gives an additional $260bn. This gives a $1tn total budget, which is significantly larger than the entire global air travel industry that it seeks to displace. I call snake oil on this. Also, the ET3 has been around since 2007; why is EETimes only reporting on it now?
