Nobody thought Elon Musk could land a rocket on a barge...until he did. 

It remains to be seen, but if he can create a hyperloop which does for terrainian transport as his Falcon 9 rocket has for space, we might be reading a whole lot more about vacuum tubes in future editions of Trains!

Maglev has also been tested, demonstrated, and put into regular service. However, it hasn't caught on due to cost and flexibility issues that I suspect the Hyperloop will share.

I tried to sell my two cents worth, but no one would give me a plug nickel for it.

I don't have a leg to stand on.

Elon Musk comes across to me as someone who honestly believes that technological advances will somehow solve many social problems.  The ability to land the first stage of a launch vehicle on a barge is a nice trick but is it really worth the expense and what does it accomplish that hadn't already been done with the Space Shuttle?

Musk has yet to demonstrate that he can mass produce electric cars at a level that can eliminate an 18 to 24 month wait after you place your order.  I'm not sure that the hyperloop can be operated and maintained with the precision it appears to require.

The effects of sudden decompression in a vacume on the human body is not pretty. Think Explosive Decompression!!!

From USA Today.  Musk looking to be able to tunnel "at a snail's pace" between NYC and Wash., DC.

Elon Musk aims to revamp tunnel digging
Strikes deal with Wis. firm to build underground rail
Nathan Bomey
@NathanBomey USA TODAY
Billionaire CEO Elon Musk is known for his California rocket and electric-car businesses, but he looked to the Midwest to show he is serious about building an ultra-high-speed underground rail system from New York to Washington, D.C.
In pursuit of a massive tunnel boring machine to innovate yet again, Musk struck a deal with Super Excavators in Menomonee Falls, Wis. He is drawing upon the 67year-old contracting company’s expertise with a goal of developing ways to dig tunnels faster — an accomplishment that could dramatically reduce the cost of bringing his latest dream to life.
Musk, CEO of both automaker Tesla and rocket maker SpaceX, has quietly assembled a team of advisers to aid his latest start-up, which he appropriately named The Boring Co.
He tabbed Super Excavators as temporary consultants to help get the machine up and running.
The previously unearthed ties between The Boring Co. and Super Excavators reveal fresh insight into how Musk has become serious about tunnel technology. In July, he teased that he had received “verbal” government approval to build a “ hyperloop” rail system to zip passengers in magnetically levitated underground rail cars running through tubes from New York to Washington, D.C., in 29 minutes — a 226-mile trip that normally takes nearly three hours by the fastest train.
“It’s always good to have an innovator looking at a process,” said Peter Schraufnagel, president of Super Excavators. “ We’re excited to see what comes out of this.”
When Musk confidant, SpaceX engineer and tunnels project leader Steve Davis approached Super Excavators several months ago, the Wisconsin company had a ready-made solution.
The Canadian-made boring machine is several hundred feet long and 14 feet in diameter. The giant machine has bored holes for sewers in San Francisco and a flood-control project in Indianapolis.
Schraufnagel declined to say how much Musk paid, but buying a used tunnel boring machine can cost several million dollars.
Musk’s goal is to create a machine that can tunnel through the earth as fast as a snail, 10 times faster than current technology.

The barrier is not having sufficient factory infrastructure, not technology.  Perhaps he'll buy some underused assembly plants from the BIG 3?  That would be somewhat analogous to Amazon's buying Whole Foods to get into the grocery business quickly.

Space Shuttle really wasn't all it was cracked up to be. The goal of Falcon 9 is to relaunch within days, not quarters. The launch costs of the Falcon9 versus a Space Shuttle are completely different leagues. 

Musk is also just ramping up production at Tesla, give it time.

Two things:

No one in the industry thought SpaceX wouldn't be able to do it. Every player in the business had subscale prototypes and the concept dates to the 60s. There's nothing particularly groundbreaking about it. The only difference is that SpaceX is willing to take the mass penalty on the first stage and it isn't clear if there's any real savings in refurbishing a first stage. 

Secondly, if Hyperloop does what Falcon 9 does...cost roughly the same but have no major advantage over a competitive machine, but everyone fawns over the guy running the place?

Hyperloop is going nowhere, in my opinion.   Technology is not at the point where that makes sense with either the electromagnetic model or with the vacuum model.   The ticket costs to support such a system long term would be astronomical and the capacity limitation on how many people could be moved between point A and point B in a given timeframe would be limited as well driving up ticket prices further over time.

Many of us are still waiting for Tesla to be self-sustaining.    At some point the government aid as well as the junk bond sales will dry up.........then what?
