- How do we imagine the transportation of the future?
Delft Hyperloop (delfthyperloop.nl/en/team) is a student team from Delft University of Technology, located in the Netherlands. With 39 engineers, they are competing in the 2019 SpaceX Hyperloop Pod Competition, a competition for student teams around the world to come up with a concept vehicle that can travel as fast as possible in a vacuum tube that is one kilometer long. Why? The transportation industry is in need of a new, innovate form of transportation: the Hyperloop. Delft Hyperloop is a student team from TU Delft, located in the Netherlands.

Which data did they use to get the energy consumption per passenger-kilometer of the Hyperloop? This parameter is highly variable and decreases as the tube length icreases. This is because the biggest energy consumption of the Hyperloop it's its acceleration up to terminal speed and this energy is better utilized as routes get longer. Also, increasing the number of passengers per pod helps to reduce the parameter. So, long routes (500 km, for instance) and with 30 passengers/pod this parameter goes below that of high-speed trains.
So just how many cubic meters of air do you need to evacuate from a tube that is say... 750 km long? And then you need to maintain that vaccuum...
Five years after the first announcement nothing off the new concepts of Hyperloop have been demonstrated.
No vacuum tunnel, no hyperspeed, no idea how to build a vacuum tunnel of more than a few hundred meters.
Hyperloop is still a hundred year old dream.
I really wonder how it can really address the issue of transportation of people in large quantities.
I can't wait to hear about the first person getting stuck in one.
At least it won’t be as bad as with planes 😅
@@VictorECaplon What do you mean? Most accidents with airplanes don't result in death...
The hyperloop sounds kinda unrealistic. I bet this is how cars and planes sounded at first. However I would be scared of the fact that a crash could happen at 800mph, it would be hard for me to fine such transportation safe.
I am disappointed. They skipped the real problems. How to make and sustain the vacuum, actual safety mechanism, thermal impact of the tube shape etc.
Disappointed? That's hypeloop for you: Broken promises.
This is not even close to being a challenge. This will never function as originally described and I will be mildy surprised if anything resembling the original plans is even built.
So... how do you keep the tube from collapsing if you put a dent in it?
There is no reason it would collapse on itself by denting it. Have a look at oil&gas lines.
@@herrjonna2007 Oil and gas lines are filled with oil and gas, not a vacuum and they don't have a train going through them. And they still manage to break.
@@schwarzerritter5724 indeed they do break, mostly because of salt water corrosion, but the pressure they experience is greater than the pressure-difference of 1atm to 30-200.
@@herrjonna2007 If you take a wire, is it easier to bend or tear? You know, grab it on both ends and pull until it rips or just bend it until is is not completely straight.
That is the difference between atmospheres higher and lower 1. Lower than 1 is bending a wire, higher than 1 is tearing the wire.
@@herrjonna2007 pipelines have high pressure inside in contrast to the hyper loop idea. Although a cylinder is the perfect shape for an inner vacuum, it is highly unstable when the shape has defects. A dent would lead to a catastrophic chain event where the entire system would collapse in itself.
This is one of the many reasons the hyper loop will never be build.
Man, that would be so cool!! You ladies are awesome 😊
Not near homes! It's amazing the tricky advertising that sales ideas and steals people's land. They want to build in a very heavily populated area filled with homes and schools.
The same can be said for interstate highways. Infrastructure, especially if it is not built underground, requires land. Some of that land may need to be acquired from others in return for compensation of fair market value of the property. When connecting cities with transportation infrastructure it is impossible not to build in heavily populated areas, however such projects can benefit society as a whole. This is certainly the case for hyperloop as it would allow people to easily commute to work while shaving off CO2 emissions without having to pack in expensive overcrowding cities.
Your proximity to highways can also negatively effect your health as well due to potentially cancer causing particles emitted from the burning of fossil fuels and can cause lung problems for those who live near the highways, including children. Not to mention that highways take up so much room along with lane expansions that takes land from the sorrounding neighborhoods.
If we are serious about the health and safety of our children and the preservation of land and private property, then we should remove expansive highways that cut straight through our cities and fund more green public transportation initiatives.
That is a healthy cautionary concern. Hyperloop is nearly evacuated and the pods are touchless. Therefore the sound will be much less than any transport. And its footprint and interference with existing roadways is minimal as it can go over or tunnel under them.
Those pods can barely hold as many people as a bus, maybe for connecting small cities together, or to bigger cities it would be good, but most HSR trains like the N700 shinkansen can hold over 1000 people comfortably per train. And once the SC Maglev with its 375mph speeds become viable, Hyperloop will be in alot of trouble.
That's the point. It looks like something that is already dead even though is not born yet. Waste of time.
Maybe they can use the technology for vacuum tubes - resistance of the tube dand how to evacuate the air efficiently - in the future, and then implement them to the electromagnetic trains that already exist.
You can keep sending pods every few minutes one after the other the tube can hold multiple pods at a safe distance easily.
It seems to me that Hyperloop would converge with SC Maglev if it continues to evolve.
@@rch5055 it makes sense. Unlike Musk's statements - one of his internship could make it -, it'll take very long to get there. When the vaccuum tube is totally ready, certainly it'll converge to other train kinds.
You are brilliant!!! Thank you for what you do
The hyper loop is amazing
So very ready bro see this thing up and running!
I ve heard about this tech. for years and it s not making much progress just alot of big talk, talk and more talk.
Yeah, except this talk started 6 years ago. The car was patented in 1885, one of the first available cars came in 1908 and even then the car was not as extensive as it is today. The human took millions of years to get where we are today. Progress takes time.
@@Azagro You gonna be hearing more of this kind of big talk for another decade. Hyperloop in Mubai, Cali, India e.c.t. just talk.
Azagro Yeah that’s true. Recent technology such as the smartphone have grown quickly. However most tech takes decades to advance such as the internet, planes etc. Hyperloop uses maglev technology from what I’ve heard and it seems that the Asians seem most comfortable with maglev technology currently.
@Azagro Not a good point. Development speed has increased with time as well. However all the technology for the Hyperloop already exists. There are just limits to that technology which prevent this particular system from being built. They haven't proved a single one of the original features proposed. No vacume tube depressurised to the specification. No tests done with a maglev of any kind. Not even a decently long tube (5km or so) built to assess thermal expansion. NONE of this, in more than 6 years. But they are still all over the work under different names asking for money.👌
So.. in future we have fast Space-X Falcon Rocket Jump to travel around the world.. and then we have Space-X Hyperloop for fast travel around city? country? ...
That's Amazing!!
Goodluck keeping the tubes safe form Terrorist Attacks.
Thunderfoot........................
Let's see who gets the last laugh.
@@UpHigherMusicOfficial we already know the answer 😂😂😂
@@samuelaubrey2612 we'll see. I may revisit this comment in a few years
@@UpHigherMusicOfficial hyper loop is a joke buddy, keep dreaming 🤣🤣🤣😂
@@samuelaubrey2612 oh we'll see. A company will manage to make the Hyperloop technology work, whether it be Hyperloop One, HTT, or the knock off in China.
i am speed
Thunderfoot was right on this one. This will never happen. It’s too expensive, too dangerous, too impractical. There are too many issues that havnt been solved. This is about as good an idea as the monorail.
I like Elon, but he didn’t come up with the idea, and there’s a reason he didn’t invest any of his own money in it, said a lot.
dit idee is minstens 40jaar oud....lees maar een paar scifi boeken
Hyperscam!
Right you are, good sir. And very succinctly put, I might add.
Still pushing this fantasy project. It is the Theranos of transportation. It is a zombie project.
More hyperloop nonsense
Tourism is a huge contributor to carbon emissions. You shouldn't be thinking of alternative ways to travel. You should be thinking of not travelling at all, except in cases of emergency or essential work travel.
Kellen Sarien This is electronic though. It can use renewable energy.
