One challenge I see is, how can we create and maintain a vacuum in such a long tube? IMHO even without accidents or deliberate sabotage that would be difficult.
@joeybulford5266 So, there are no competent engineers that can calculate a sufficiently resilient structure? We don't have aircraft, dams, bridges, buildings and nuclear reactors? There is no way to rapidly and uniformly restore ambient air pressure within a few seconds? It's not made from sheet metal.
I think the 'under 500 miles' connections are generally better of with regular high-speed rail. Investments are way lower than a new unproven technologie. If (and that is a big IF) a hyperloop has a business case, in my opinion it must be oceanic crossings. For example, Paris to New York or Tokyo to Los Angeles....
My main problem is if a train breaks down it will block the entire thing i also think engineers will probably have nervous breakdowns trying to keep the thing maintained it just sounds so impractical. Then they is cost both the UK's hs2 and California's high speed rail has cost well over 100 billion USD so this is certainly not going to be cheaper
The biggest problem is that the tube will expand and contract with temperature changes throughout the day. And it’ll result in pressure fluctuations which will absolutely result in people dying. THAT’s the biggest problem.
The video neglects to mention some important things. 1) Maintaining a train sized vacuum tube is beyond current technology. 2) Any breach of the vacuum tube with a train inside would result in an implosion similar to the one suffered by the Titan submersible. Everyone would be dead in moments. 3) To reach the desired speeds, the tube would only be allowed a slight curve, requiring the actual course to be closer to a half parabola, if not completely straight. 4) Passengers could only exit the train after the section of the tunnel depressurized.
1) the vacuum isn't a full vacuum, just a medium vacuum. So even if there was an air leak (or even many air leaks), it wouldn't affect the tunnel. 2) we have strong enough materials like cold-rolled steel that could easily hold up the pressure of the outside atmosphere without imploding. 3) the pod could slightly slow down at curves. It doesn't need to go 760mph for 100% of the journey lol. 4) not a big deal. Just put a pressurization/depressurization chamber at each station.
We broke the sound barrier by getting up into the jet stream which is spun west to east by the earth's 1,000 mph west to east rotation. So instead of depressurizing the hyperloop pressurize it with 800 mph jet/slip stream air flow.
A chief benefit of creating a high elevation environment down low is saving all of the energy required to climb to that elevation and still having the benefit of low air resistance. By using a charge of air to blow the carriage down the pipe , you have to evacuate the system every time you send one down the line. Electric linear motors are more efficient and can be used for regenerative braking.
I’m not worried about getting to where I’m going 30-50 minutes faster than the next fastest option but more importantly is having more space to work while I’m travelling so the time I’m travelling can be used efficiently.
To much land, energy and structurally inefficient, noisy, creates slums, dirty, and dusty. Everybody loves a rail train. That is true enough. Nobody wants to live near one.
I'm going to go out on a limb and guess this would be useful off earth in a zero or near zero environment and this is being done to pretest something for a colony concept. Most of spacex's stuff seems to be being done for this reason.
It will never happen, if it's actually built it will be extremely expensive and will not be widely used, just build normal trains and high speed rail and stop giving money and attention to billionaire's vanity projects
Let's just reserve this for the connection between future Moon (no atmosphere) or Mars (little atmosphere) settlements. Yes folks, there the vacuum is virtually free of costs, nothing complicated about it and may also certainly be used and profitable for short trips.
I thought Elon admitted that he brought up the hyperloop, whose concept is about a century old, to try and kill the rapid transit train being built between SF and LA.
Last point. The lesson we may all need to learn. Wealth is not a sign of intelligence, and we need to stop listening to the second biggest man-child in America.
He must continue this project and fix those engineering and maintaining challenges, because it's the future. If Elon Musk is't gonna do it, some one will one day.
The cost of having a Hyperloop in the UK between London and the North would be way more affordable that the current HS2 project that is close to £160bn. Hyperloop type projects will be necessary to transport large amounts of people in a quick low CO2 way.
A railway (H-L is one, basically) in a massive tube with vacuum systems, maglev, and all that involves will be cheaper than a railway on wheels in the open? Musk dreamed his low cost by assuming H-L wouldn't need to buy the land beneath, and by making the tubes so small that passengers have to lie nearly flat. As for CO2 : HS2 is electric anyway. A lot of HS2's costs are planning and legal - for H-L it would be even higher.
1:35 why does the hypothetical hyperloop tunnel from LA to San Francisco appear as a perfectly straight line? No land based or underground route is ever perfectly straight.
Musk did not propose H-L in tunnels, but raised on pylons; and he did not propose maglev, but an "air hockey table". He got the price cheap because the tube he proposed was small (passengers would nearly have to lie flat) and he assumed H-L would not need to pay for the ground underneath. All utter bullshit of course. BTW, Hyperloop One have gone bust since this video was made.
This is hilarious. On paper everything is simple. All it takes is an earthquake and the vacuum tube becomes an impenetrable tomb with one hundred people in a panic.

not that hard when you are an ingineur.
No. We can’t. It’ll kill people.
Because vacuum pumps are not invented yet?
@@markharmon4963
Because atmospheric pressure will crumple the tubes when you suck all the air out

gladly the test tube has been removed and sold as scrap.

I thought we’ve moved past this hyperloop bs🤔🤔
oh, dont worry. this will get a ton of views.
hyperloop will never work in the real world, but... as a theoretical transportation mode, its fun
@@nioxic77 Why not teleports? Even quicker and just precisely as realistic as hyperloop. (i.e. zero)
Apparently not, my University still have a Hyperloop club

He should have just daid hes building a Stargate......itd have been as realistic

Hyperloop was never intended for "mass transit", moving mass number of people in any given day.
If you want "mass transit transport", go with trains
To much land, energy and structurally inefficient, noisy, creates slums, dirty, and dusty.
Everybody loves a rail train. That is true enough. Nobody wants to live near one.
@@markharmon4963 and too slow & expensive
@@TSERJI Yeah, I was comparing to the possibilities of hyperloop. I hope that was understood.

Yep. It would work great on the moon. Wouldn’t even need the tube. It’d prbly just look like a train.
Now that's just silly. It would never work.
It will never happen, if it's actually built it will be extremely expensive and will not be widely used, just build normal trains and high speed rail and stop giving money and attention to billionaire's vanity projects
True
Except high speed rail won’t happen here either
@@HablaCarnage63it's happening. Miami - Orlando is operational. Vegas - LA in construction.

The high speed,and the cycling of magnetic fields. I am just curious as to the effects on the human body. Wonder if that can be tested. Just curious.
Common people will never trust to travel in this closed claustrophobic moving tombs. This transportation system has ZERO appeal and is set to fail.

China has succeeded the test last month, will make the first route from Shanghai to Hangzhou in 7 minutes.
They are lying. Tech doesn't exist.

Hyperloop is vapor. What you have now is real. You can't compare vapor to reality.

Elon needs to find inspiration in the wings of a butterfly and forget about rocket trains and space ships to Mars.
HSR is good enough maglev train still too expensive Hyperloop isn't realistic
It's not going to happen for a multitude of reasons most of which are technical and not feasible so let just move on shall we
1:35 why does the hypothetical hyperloop tunnel from LA to San Francisco appear as a perfectly straight line? No land based or underground route is ever perfectly straight.
Because it is a geographic lesson showing the scale and region of the problem.
This is the future! Haven't you ever watched sci Fi. It doesn't have to make sense. It's the future 😮😮😮 WOW.
