There have been a few Maglev attempts , Japan's line will fully open in 2045...at a cost of 65 billion.... Why would this be any cheaper? Building anything elevated and that high won't be cheap , then you have NIMBYs who hate all things elevated.. While he says 6 billion , I think it will be anywhere between 45 and 60 billion.

It is not maglev. It is a partially evacuated tube hung over the freeway. I would think some relatively thin wall stuff in a frame to provide strength. trqaction is by linear motors a well known technique. He does have this bit of sucking in the air in front ot the train for flotation and to thin the atmosphere and I presume the capsules are pressurized.

His real claim is that it should cost a factor of ten less than high speed rail and be much faster and cheaper. If anywhere near true he has a winner.

I can see that since it is for 900 miles plus trips he says. There is not the need to serve food and have sleeping quarters which is really costly on rail of any kind. Probably could make a profit where high speed rail can't an be affordable to most.

It isn't mag lev. it doesn't require nearly the same infrastructure. It doesn't require much in in ROW.

That being said, he'll have to build a proof-of-concept at least before I can take this seriously. For now - science fiction.

Nope. Science speculation perhaps . But does CA want to bet 40 or 50 billion it is wrong? I would not.

The HSR proposition in California is preposterous. The joke is, it isn't even high speed rail - it's a bit better fast than the existing rail for short stretches. It's absurdly expensive has way way too many stops, will cost ungodly sums in condemnations.

But that doesn't mean the EM's Hype Loop is anything but well, Hype. History is littered with grandiose transportation systems. I don't know if this is one or not, but right now it's some sketches and some guess work and not a single small scale test to back up the incredibly complex tasks it would have to achieve.

Let's see a scale model work and then I'll be on board for the Hyped-up Loop. Until then, it's a good story.

Better plan,, try this between LA and Las Vegas.

The issue is the infrastructure to make it happen.

Why not fix the messed up water systems, electrical, and current road systems, including many bridges that have not been replaced since the Depression. Those issues need to be addressed before this... Reality check.

Why would the superhype loop work any better between LA and LV?

There's nothing wrong with wanting to do something between LA and SF. I just think this is getting a lot of undue attention. Personally, I' wouldn't be surprised at all if this is a little joke a billionaire is having over us.

Amen!
Whenever I see a proposal like this or even for massive high-speed rail networks all I think is "travel options for the well-off". Recouping costs in a reasonable time frame for these projects requires fares that only business travelers or 1/2/.../5%'ers can afford. Do you really want to use tax $ that could be spent on other, more socially beneficial projects just so we can have some cool technology? I grew up during the early days of the space program - ever since then I've loved reading about and using new technology (biomed, computers, etc etc), but spending who-knows-how-many billions on right of way and infrastructure for what ultimately benefits a very small number of people is narrow minded.

Some criticisms of the California vacuum tube by Alon Levy:

Loopy Ideas Are Fine, If You’re an Entrepreneur | Pedestrian Observations

Some of the more culture related comments:

There is a belief within American media that a successful person can succeed at anything... The people who are already doing the same thing are peons and their opinions are to be discounted, since they are biased and he never is. He doesn’t need to provide references or evidence – even supposedly scientific science fiction falls into this trope, in which the hero gets ideas from his gut, is always right, and never needs to do experiments.
