Wow didn't know Norway's education was so shitty. Hyperloop is not going to be a perfect vacuum because that would require a lot of energy to maintain, but it's going to remove most of the air to lower the air resistance to levels equal to what is 200,000 feet above earth. The rest of the video relies on the assumption that it's going to be a perfect vacuum, it's not.

t. Engineer with physics background

musk is a very effective scam artist

>>136243338
He actually addresses this specific point you made in the video. The pressure at 200 000 feet is so close to vacuum that you might aswell consider it a perfect vacuum. If you were an actual engineer you would know that.

>>136242519

Thundercuck is not a physicist but a chemist. He makes dozens of false claims regarding Hyperloop. He fails at very basic level, for example he doesn't understand that in case of depressurization event the maximum speed the air can travel in the tube is speed of sound and because the speed of sound in vacuum is zero it creates a pressure gradiant instead of a homogenous wall of air traveling at speed of sound at 1 atm. He also uses a video of 12 gauge sheet steel container imploding because of vacuum to prove his point about how dangerous hyperloop is which is a dishonest since he knows very well that Hyperloop or any other kind of vacuum tube is not made out of thin sheet metal.

He also seems to have some kind of personal vendetta against Elon Musk as proven by his ridiculously snarky video about the Falcon 9 refueling accident.

Personally I don't think Hyperloop is feasible because of cost considerations but as an engineer I lost all respect for thundercuck when he started to publish these click baity and pseudo scientific videos. In retrospect when watching his older feminist videos it's clear he uses exactly the same kind of strawman argumentation he accuses others of. He seems like a narcistic fuck who loves his own voice too much.

> On July 29, Hyperloop One conducted its second full-scale hyperloop test, flinging a pod the size of a small bus down a vacuum-sealed tube at 192 miles per hour. As far as Hyperloop One’s CEO Rob Lloyd is concerned, this is it: a functional hyperloop. Now, he only has one question: “Who wants to go first?”

> Lloyd spoke to Inverse on Wednesday morning, the same day the company officially announced the successful test. Lloyd recognized the technology still has a long way to go before it’s capable of carrying human passengers or enabling hyper-fast city-to-city transit like Elon Musk’s vague plan to connect New York City and Washington, D.C., but the latest test makes Hyperloop One’s claim to the only functioning full-size system pretty unimpeachable. Now, he says, it’s time to start selling it.

> Another thing Lloyd’s really not worried about is speed. The July 29 test propelled Hyperloop One’s pod at 192 miles per hour, 2.7 times faster than the 69 mph first test. Musk’s initial white paper for the hyperloop in 2014 envisioned the system reaching speeds of up to 700 miles per hour. While that hasn’t been physically tested — not even close — Lloyd says it’s just a matter of scale.

> Instead, Lloyd says the company is focused on getting an airlock system in place. Human tests for the system are still at least a couple of years away. He says the company will have to work with federal regulators to make sure the system is tested safely and legally.

Because the people who claim it is not possible according to the Laws of Physics have never actually taken a degree in physics. It's like people who talk like they are an authority on quantum physics because they watched a decades old video, that is factually incorrect, about the double slit experiment.

Currently work in physics at big ten university. Also an adviser for our hyperloop student engineering team. There is nothing impossible about the physics or its construction. It's only for fast travel between densly populated areas like La and San Fran. DC and New York, etc. Between 150 mi and 500 miles, below that cars are better, above it planes are, economically speaking. The steel tubes that hold the near vacuum are 1 inch thick, 100 ft segments. Industrial vacuum pumps are placed every 2 miles or so. I mean, come on, it's not a scam and relavtively simply in principal. a linear induction motor pulls a pod with a halbach array of magnets underneath it which repel its mirror image induced in the aluminum track below, guided by an I beam and magnetic emergency brakes attactched to a hydraulic piston.

First off, I'm 100% sure that's a complete fucking lie due to what you're posting.
Second, why are you pretending that pressurized travel is somehow a death sentence if you supposedly work in an industry where it's the norm?

lel. he just assumes that the tube would not have any form of support system. like hatches or vacuum pumps, cooling systems etc. etc.

For the loop supporters what benefits are offered over a 'conventional' SCMaglev technology?

All I can figure out is that the resistance is lowered but the cost massively increased over already expensive rails and you now have a massive vacuum chamber all over the country side waiting to implode.

Physicist checking in. Haven't watched the video because Youtube autists are dumb as fuck in 99% of the cases but the pressure at 200k ft/~60km is 0.1-0.15% of atmospheric pressure. Assuming the simplified version of 100.000Pa at sea level, that means you have 100-150Pa, or in vacuum technology where mbar is usually used as the standard (for non imperial ubermenschen), 1-1.5 mbar.

Now, anyone claiming that this is "near perfect vacuum" is a complete imbecile who doesn't know what he is talking about. To create a pressure of 1 mbar is fucking easy with readily available pumps who are not even that expensive. Nor is it any kind of "special" vacuum, it's simply standard as fuck. Regular applied pumps in vacuum technology go down to 10^-2 till 10^-4 mbar, which is already a factor of 100-10000 better than needed for the hyperloop. The next stage, usually done with turbomolecularpumps, reaches 10^-6 till 10^-8, sometimes even 10^-9. So we are no a factor of ~ 1 million to 10 million better than actually needed, with a pump that can run continuous at the cost of roughly 5k a piece. Going even further, for instance to reach the pressure you have inside the LHC, which is one I would call close to "perfect vacuum", you usually use cryogenic pumps, either liquid helium or simply cryopumps (basically a refrigerator running an extremely well designed sterling cycle with high pressure helium gas (15-20 bar) as the working gas). With that, you go into the 10^-9 till 10-12 mbar, depending on how will your recipient is sealed.

Tldr: Creating a vacuum of around 1mbar for the hyperloop if fucking laughable and can be done with "from the shelf" pumps... you just need lots of them for a long tunnel. The particle tube of the LHC is 10^-13 mbar, which is 10 billion times better than what is needed for the hyperloop. It's tube of small diameter with 27km in length. Now shut the fuck up brainlets.

>>136249735
>Three times the speed and modular, off site construction lets them be built faster, easier and cheaper.

How does the hyperloop build a maglev rail inside of a vacuum chamber for less cost than a maglev outside of one?
The speed is also just a bit more than twice the SCMaglev, 1220km/h vs 603km/h. And the SCMaglev isn't capped at 603km/h that's just it's current record speed.

The aerodynamics aren't really huge problem in a nation that's not going to need as many tunnels as in Japan. Tunnels in Japan are generally the limit on speed due to air compression inside the tunnels.

I'm just not sold on how this is better.

Reread my post however many times it takes for you to understand it.
It's the same reason building cruise ships is cheaper when modules are built in separate shipyards and then welded together.

Modular design is a HUGE boon to constructing literally anything.

>>136250155
My objection isn't that it's not a 'perfect' vacuum it is that their is any meaningful difference in terms of structural integrity of the tube material between 1kPa absolute and 0.001kPa absolute. Those are both huge vacuum with a nearly identical material requirement and nearly identical raise due to failure.

>>136251057
I know they're not.
The only modular part of maglev is the concrete slabs it's built on.

>>136250885

Yeah structural integrity is no problem at all. We apply "X ray windows" at accelerators/particle traps so that x rays/gamma rays can travel outside of the accelerator through such a window onto an external particle detector. These windows are usually 5-10 µm thick aluminum foils an survive the pressure difference from 1000mbar/100kPa down to any vacuum humans are able to create.

To create huge tube out of this you would have to change it a bit, but structural integrity is literally a non issue for the hyperloop.

>>136251192
That's strange with half inch thick steel cylinders with domed ends failing at 50kPa.

Maybe we should be building vacuum vessels out of 10 µm thick aluminum foil. That or you are being intentionally misleading with aspects like the window size or if it does actually have the pressure difference supported by the foil.

>>136251910

Of course the windows are small, tiny, compared to the tube. The diameter of a window is usually just 2-3 cm. But much much larger vacuum facilites are used literally everywhere, we have already around 30 in our institute alone with the largest vacuum chamber of these being a cylinder of 1.5 meters in diameter. I still can't see how this is supposed to be a "groundbreaking" issue, more like "well we have to find a way and will have it fixed in a reasonable amount of time", just like with any experiment every created.

If I would design the hyperloop I would put the people in lying down like in a bed to reduce the diamenter. 2 Meters diameter already seems a bit excessive to me.

>>136250155
>you just need lots of them for a long tunnel

This is going to be one of the main problems with making it into a full blown transportation service. A small scale proof of concept under controlled conditions is a fuck of a long way from an economically viable system running and being maintained on a daily basis.

>>136252517
Do you get the issue a 3.3m in diameter vacuum chamber that's also 1000km long is a bit different of a beast than your 1.5m by what 5m chamber?
The issue isn't that it can't be built. Or that it can't have the vacuum applied to it. It is that the energy of that vacuum is too dangerous and that over that length you will get a defect in time.

We have reasonable good idea of how hard it is to make pipes given the number of pipelines around the world and how often they fail or spring leaks. The difference is that when the hyperloop springs a leak it implodes violently and destroyed every pipe section in a cascade failure.

As for the size, you need the magnetic levitation machinery which has a size requirement on it as well.

It's another "anon doesn't understand some science / engineering and refuses to listen to several qualified posters" thread.

>>136253735

Lot's buzzwords in your post but absolutely no substance.

You should literally go back to high school physics class.

>>136242519
You shouldn't believe thundercuck in everything he says. The hyperloop IS possible if you use smaller tunnels and less of a vacuum.

>>136242611
He is referencing a hollywood movie for scientific arguements for fucks sake.

>>136253735
>when the hyperloop springs a leak it implodes violently and destroyed every pipe section in a cascade failure
>believing thundercuck
A section is likely to implode, but not the entire length as once air enters the vacuum chamber, the equalization in pressure would be faster than cascading implosion. Unless implosion doesn't actually require any energy, then yeah, maybe the tube will implode while the pressure difference between the inside and outside are equal.
The difference between people like thundercuck and actual engineers though is the fact that engineers don't dismiss an idea based on the potential for a problem, they find ways to solve them.
There are numerous solutions, like using the forwards momentum to drive a compressor fan that levitates the train by diverting air onto the track; this would mean you could kill two birds with one stone, reduce the required vacuum, lower the power required for each LSM and increase the safety in the event of a loss in pressure.
Also keep in mind that the same system that powers the trains could also be used to slow them during an emergency, LSM's double up as breaking systems, and roller coasters have been using them for decades to slow trains that weigh around 10-20 tons.

1) That's not how pressure works in a large vessel. There wouldn't be a "wave" like someone detonated TNT. Pressure equalizes and dissipates through a vessel. The only significant risk for depressurization would be right next to the puncture itself.
For examples look at this video some guy posted earlier
https://www.youtube.com/watch?v=AEtbFm_CjE0
tl;dw a huge pressure differential is basically unnoticeable even from inches away. It's only when you get int he way of the flow that you get fucked.

2) The pressure differential would only affect you if you're within the the vessel where the breach actually happens (the tube itself) which passengers would not be. The cars in hyperloop will be pressurized. All a breech int eh tube would do is equalize the pressure inside the car with the pressure of the tube. Passengers wouldn't even notice a difference other than the ride getting rougher due to turbulence.
