The Hyperloop: BUSTED
cdev:
When a country joins the WTO it has to buy into the WTO ideology of "progressive liberalisation" which means that eventually everything must be privatized.
So, unless they had public services before their date of accession, and haven't changed them at all or charged money for them at all, or explicitly carve them out, they have to suffer a death of a thousand cuts.
What people need makes no difference it seems. Its like an inside job to steal the whole planet where they all help one another rip off the public everywhere.

The only place where I've seen the type of outrageous security you suggest is in the US really, and the security for aeroplanes is still a joke at the end of the day.

It's almost all just theater to make it look like we're "doing something" to keep people safe. The system is full of gaping holes and it's trivially easy to sneak contraband through. On one occasion I flew from a small podunk airport, the sort where you walk through an old fashioned metal detector then wander out onto the tarmac and climb into a plane, into a major international airport. It occurred to me when I arrived that I was standing within the "highly secure" terminal area having completely bypassed all of the security and body scanners, simply by flying a short distance from an airport lacking all those facilities. It's a joke.

Another first simple step is to stop and think why no one has done this old idea before:
Has there been some radical breakthrough in maglev technology? No.
Has there been some radical breakthrough in ridiculously large scale vacuum tunnel technology suitable for human carriage over hundreds of km? No.
Has there been some other radical breakthrough in the transport market space? No.
Has there been some other breakthrough in cost reduction in anything to do with this? No.

You can turn this reasoning around quite easely: if there is no demand for a radical breakthrough then it won't happen. Chicken & egg until someone throws serious money at the problem and makes the breakthrough happen. Creating something new often requires solving technical issues nobody has solved before.

People bitch and moan about dumping money in to force technology to evolve but it worked with LED lightbulbs. When they first appeared on the market they were very expensive, $50+ per bulb. Efficiency mandates and subsidies got the ball rolling and now they are in widespread production, readily available and dirt cheap. Without the mandates many people would have been content to keep using incandescent bulbs, oblivious to or not even comprehending the fact that the total cost of ownership including electricity is far more expensive for the "cheap" incandescent bulbs and the LED tech may not have caught on at all in an entirely free market. People are highly resistant to change and sometimes a visionary has to come in and give something a nudge.

And sometimes, just sometimes, an idea will always just remain fundamentally impractical.
IIRC there is someone on this forum who is part of one of the top HL design teams who have published very details technical papers on it, and even they admit that the vacuum based HL idea is poorly thought through and basically may not happen.
And make no mistake, you can't separate the vacuum idea from Hyperloop, because without it it's no longer the Hyperloop idea.
A vacuum based passenger carrying intercity HL will never happen, I'll bet you a bitcoin on it.
