Why don't all the smart engineers of the world realize a hyperloop doesn't need a vacuum? Even I can come up with ways for zero air resistance without creating a large, infeasible vacuum.

>>105722463 (OP)
If it doesn't have a vacuum what is the benefit over a normal train?

>>105722487
No air resistance despite no vacuum, can't you read?

>>105722487
I'm no /sci/tard, but I am guessing the other half of the technology will be in the tunnel and how it handles the movement of air inside it while this beautiful thing passes through it.

>>105722585
Now you have a train, that is acting like a ram who is pushing all the air inside of the tube and creates huge amounts of pressure.
>>105722542
Explain your position, you literally didn't explain shit.

>>105722463 (OP)
Hyperloop was just some shit Musk came up with to prevent California from funding normal rail.

>>105722590
Not that pseud, but probably something that moves the entire column of air in the tube with the train. Extremely inefficient and retarded, but honestly I have no other idea.

>>105722590
I haven't patented it yet. It's not a hard problem, though. Take a guess.
>>105722585
no, that's now what I have in mind. Moving air is a very old idea

>>105722606
What if you created a bubble of low pressure using shapeshifting that activate when the train passes. Sorta of a wave function that proceeds the train, Bernoulli effect like or something. Little 3D printing panels/paddles that quickly increase the potential volume as the vehicle moves. Or is that vacuum?

>>105722602
That is fucking brilliant. What would yo call it though?

>>105722648
>but probably something that moves the entire column of air in the tube with the train.
How is that inefficient? Are u imagining big fans making 500 kmph winds?

Literally does not matter if I imagine big fans or not, this is physically retarded.

>>105722726
lol, I will save this for when my idea, which you didn't come close to guessing, gets patented.

>>105722463 (OP)
The entire air resistance thing is a strawman. We don't need vacuum to move fast. Just use more power.

>>105722606
>Explain your position, you literally didn't explain shit.
I won't make you rich. pretty simple though, try guessing here along with the other 'tards

ITT retarded pajeets try to reinvent the pneumatic tube system

>>105722661
The train has area, the tube has volume filled with air. Train moves its area and displaces the volume of air inside the tube. No amount of 3d printing will fix that.

why did they abandon the compressor design?

>>105722661
Yeah, let's just have rapidly moving heavy elements capable of instantly displacing enough air to create a pressure difference big enough to matter for a heavy ass fucking train. Over the entire length of train tracks.

>>105722914
Because with any other complicated and elaborate autism, its not cost effective to build and maintain, compared to a plain ol train.

>>105722937
fuck yeah. with flames and arcs of electricity, maybe even jets of steam.

>>105722487
Ever played air hockey? There's no vacuum. There's just air underneath it. There's no magnets either. Retards saw "a train" and then could only think of magnets or vacuum, when that wasnt the original paper

Do we really need more speed? Is this cheaper than a bullet train?

>>105723121
Cool, how is it better than a train. Do you think friction is the biggest problem trains have their speed capped?

>>105723121
>Ever played air hockey? There's no vacuum. There's just air underneath it.
Doesn't the air hockey puck weight fuck all?

>>105723233
Friction limits the energy necessary to move a train at a certain distance. 0 friction = forever moving with only the initial energy. Friction isnt the only issue. Environmental wear/tear is a HUGE HUGE HUGE issue for trains. They require so much maintenance due to wear/tear from the environmental weather conditions. Rain/snow/debris/sun/wind/earthquakes/etc. You have to forever maintain in the face of rapidly changing environment. Tunnels provide security from 99% of the environmental conditions that affect above ground structures. Then there's the aspect of having to share roads space with other users, humans/cars/trucks/homes/etc that slow down the speed of the train and the regulatory gridlock.

>>105722573
>expecting Mumbai Musk to actually deliver
I bet you think Rohit's credentials are 100% real too.

>>105723336
Your assertion is wrong, friction is what happens when two materials rub each other, breaks are friction. If you have 0 friction you still have other reasons why things slow down, inertia is resistance to movement.
Having 0 resistance would reduce parasitic forces but wouldn't make things go forever.

>>105723381
>inertia is resistance to movement.
Inertia is resistance to change in motion.

This seems incredibly dangerous

>>105723327
According to AI, commercial air hockey table is powered by a small blower that is generated by ~1HP of power (depending on size of the table). For a small 4 person pod (~500kg) that is pushed around, you need a ~150-200HP blower. To push that 10 miles out, you need ~2000 of them. That costs ~$20M total. If the tunnels/motors are more efficient, then only half is needed for $10M.

It doesn't need a vacuum, but without a vacuum, it creates some very interesting issues when you break sound speed inside tunnels.
Like, you know the place where people wait for the train? Yeah, it became the barrel of a weapon that will make people deaf and can even kill without any warning.

>>105723121
You know air hokey pucks will still slow down as they move along right? Not even from bouncing off the walls.

>>105722602
Wait a minute...

Air resistance is not even that problematic for HST.

>>105724465
Yes, thats because the blower handles small table size area. Its not an issue for any large scale program where you can simply install 1000 blowers. See >>105723533. Also, slowing down is fine, you need the vehicle to slowdown as it reaches destination. So with gradual reduction in blower power nearing the destination, it can slow down the pods/puck.

>Do we really need more speed?
No and yes.
Fundamentally you want speed.
But the RL problem is that the bullet trains are not being built in the first place, nor HSR of 120-180kmh conventional.
>Is this cheaper than a bullet train?
Nobody knows until a full scale model is built. Even then costs are deceptive, because you get hull maintenance with no real train maintenance, vs tracks and trains sets.

For now, Air Resistance is a part of the fuel and operation costs.

>>105724446
If treated as a engineering question the issues become a series of test to find:
1. What is the pressure needed for tunnels when not operating? This is cost vs maintenance vs durability
2. Pressure for operation, including the depressurization time, and how long before you pressurize them
3. Some kind of safety mechanism in case a operator fucks up and enters MORE atmosphere while still under high speed
4. How long do the entry/exits become, since you need to go from pressurized 1 atmosphere to whatever you find in question 2

And all of that has to be done, while asking if there is a point when conventional 180km/h HSR can still share tracks with freight goods, which means more infrastructure per penny.

>>105722982
>compared to a plain ol train

I certainly don't need your permission, and it is obvious that I have chosen already.

the real answer is magnets but people just don't know how they work yet

>>105725885
They need to rectify flat earth have a north and south pole first.

why does it need to have an aerodynamic shape if it's supposed to run in a vacuum, isn't that just a waste of usable volume to hold more people/machinery?

why not make it a perfect cylinder that fits the tube that creates its own vacuum by pushing the air as it moves with one way valves on both ends, so you don't need other specialized equipment to pull a vacuum over such a large volume.
i don't know how that tube would move without friction tho

>>105726094

>>105726296
>>105725102
lol

>>105726094
Because it won't be a perfect vacuum.
And any air left has to squeeze over the train since it's in a fucking tube.

The whole concept is retarded of course, even Musk himself abandoned it.

Im no engineer but ive long fantasized the supercavitation equivalent

>just generate your vacuum infront of it as you go

>>105723576
>English, motherfucker, do you speak it?
Yes. That's why I understand that "change in motion" is more specific than "movement".

>>105727186
>is more specific than "movement".
O'rlly? I would love to see you try and explain the difference. I doubt you will though. Not worth your time, right? ;^)

>>105726599
>plural noun: uses
No, it is just ignorance of the English language. Darpa invented AI, though, so I am sure they have found plenty of uses for it. ;3

>>105727229
Movement can be used to describe just the continuous motion of an object, so when you say "resistance to movement" that be taken as continuous resistance over time.
Change in motion refers to a instance, so "resistance to a change in motion" refers to resistance at discrete point of time.

>>105722463 (OP)
Vacuum isn't that hard to make, just pump the air out. The tech could've existed years ago but people chose to use planes instead.

>>105726672
Cavitation happens because the pressure behind the vehicle drops below the vapor pressure of the water causing a phase change. You can't really effect a phase change in the same way in air.

>>105722542
bruv you need to move a lot of air with it, that takes massive amounts of power, unintuitively

>>105727258
'uses' was used as a verb, not a noun. Try not to embarrass yourself like this in the future

>>105727288
You are conflating Inertia with the moment of Inertia. Inertia is the resistance of movement ( if it is moving it will continue to move, or if it is not moving relative then it will remain at rest relative) Everything is in constant motion, though, so for it to be specific you would need to called it specifically the ``moment of Inertia'' for it to be accurate as you just attempted to describe it.

>>105727357
>( if it is moving it will continue to move, or if it is not moving relative then it will remain at rest relative)
Yes. A change in motion.

>>105727304
You just need to be moving fast enough to create a plasma in the air

>>105727340

This is the exact problem whenever someone mentions "muh public tranways" for America. Can trains as the main or sole form of public transport be good? Perhaps better than what we use now? Of course but only if you have a high trust society. It works great for places like Japan because Japan is filled with Japanese people. Here in the US no one even wants to interact with their neighbor let alone get on a train filled with schizos.

>For now, Air Resistance is a part of the fuel and operation costs.
Cost wise and ignoring the environmental regulation pressure a current high speed train could run at 1000 km/h at sea level and still be cheaper than an airliner because electricity in general is cheap and way cheaper to operate than a gas turbine.
The problem is the terrain, tunnels are absurdly expensive and along side "railway" leveling they're the main cause of the high cost. Regardless land price.
