Don't know what's so unique about the Boring Company's technique, but if what you are saying is true, they should be used for Gateway and the Cross Harbor Freight Tunnel too. Faster and cheaper - what are we waiting for?

P.S.Their website claims their newest machine is10 times faster then existing machines. That's amazing.

That's what I've been trying to ascertain too, the company's videos aren't clear on the difference between their boring machines and a standard TBM. I think part of the difference is that these tubes are built for a small vehicle, considerably smaller in diameter per passenger/hour than a standard subway or train, so maybe they're easier to bore & excavate quickly.

Hyperloop is just maglev in a vacuum tube... It's just taking an astronomically expensive existing technology and putting it in even more expensive tubes.

Is there any barrier to it? Just economics...

Musk talks about the boring company and doesn't sound too confident.

Jeez. If he didn't treat his workers worse than dirt i'd almost feel sorry for his self-destruction.

You're right, the economics don't make much sense.

I would say there are also physical barriers. None of the Hyperloop companies have (to my knowledge) explained how they would deal with the expansion problems presented by a long, exposed steel tube. They also haven't really considered the safety implications of a vacuum breach, which could prove fatal and cause serious damage to the entire system.

Either way I see this going nowhere fast, yet the media keep hyping Elon Musk's ridiculous (and in many cases unoriginal) ideas.

Someday we will discover a test tube under New York dug by the Boring Company, 500’ underneath the Beach pneumatic subway.
