Because vacuum sealed tunnels are cheaper than welded tracks? Ten times cheaper, even? lol

For underwater tubes, escape hatches would lead to escape capsules. I should probably clarify that these proposed tubes are quite narrow ranging in width from 2' to 5' with 51" being the supposed optimal width from a cost/capacity perspective. For a 2' diameter tube you would be lying down in a capsule.

How is this not prior art? I guess you can get a patent on anything these days.

They don't envision people walking to the escape hatches. They state “In the rare event of stoppage in the tube, the capsules will be directed to the nearest escape hatch.”

Yeah, even if every passenger had emergency scuba gear and could make that trek of up to 1/2 mile to the nearest escape hatch, then what? Emerge from the hatch into the waters of the icy North Atlantic, at a depth of probably 50-100 feet below the surface?

Heh. Ever try walking up to 1/2 a mile while holding your breath?

They claim that their build costs are 1/10 that of high speed rail at about $2 million per mile for a 350 mph system. They go on to state that “Some licensees believe that cost will be so low that advertising could pay for most travel, just like it pays for TV, or free Internet.”

They plan on having escape hatches every mile.
