EDIT: WE ARE DONE FOR THE DAY! THANKS FOR THE QUESTIONS, AND WE'LL BE BACK ON REDDIT SOMEDAY SOON.

We work at Hyperloop One, the L.A. startup bringing the Hyperloop to reality.

Hyperloop is the first new major mode of transportation in 100 years. It’s designed to be safe, energy efficient, and reliable. It will take you directly to your destination at speeds of up to 700 mph, above land or underground. Here’s a video on how it works.

We just completed two successful rounds of full-systems testing at our DevLoop site in Nevada, breaking some speed records and unveiling our XP-1 pod. We’re sure you have tons of questions about our progress, so we’re making a Reddit re-appearance.

Here’s our proof.

What is in place to prevent the Hyperloop from turning into a vacuum cannon and killing passengers in the event of a tube puncture?

hyperloopone36 karma

Our tubes are constructed out of thick, strong steel and are very difficult to puncture or buckle. We’re designing and constructing the tube and pods explicitly to handle down to 100 Pa of pressure or more (equivalent to air pressure at 200,000 feet above sea level), changes in air pressure, and to safely tolerate small leaks, holes, and even breaches without suffering from a vacuum collapse.

If there was a leak or breach in our tube in an operational system air would leak into the tube. The affected vehicles would slow down due to the additional air pressure, or require a power boost to get them to the next station. The pods will be built to withstand even sudden air pressure changes safely. We will also have the ability to section off parts of the route and re-pressurize sections in the case of a significant emergency. Every pod will have emergency exits if needed, but mostly pods will glide safely to the next portal (station) or egress point in the event of an emergency. Additionally, we are building sensors throughout the system to notify of any leaks or breaches and we would be able to identify and perform maintenance to resolve any leaks quickly.

how do magnets work?

hyperloopone38 karma

Well.

-IU

suaveitguy30 karma

How much energy per passenger/mile does the hyperloop use? How do you measure to get worthwhile comparisons to cars or other modes of transit?

hyperloopone11 karma

Compared to high speed rail and maglev trains which require power all along the entire track, Hyperloop One only requires energy to a portion of the track. Specific energy use will depend up on system requirements and terrain - SJ

thegunisgood38 karma

This ignores the energy cost of pumping the air out to a near vacuum.

hyperloopone22 karma

If you meant maintaining the pressure in the tube, Propulsion power is atleast an order more than maintaining the pressure in the tube - SJ

Catanians22 karma

How would it handle movement of the tectonic plates?

hyperloopone25 karma

Seismic hazards will be handled quite similarly to how their handled in many other transportation infrastructure systems. Detailed geotechnical and seismic studies will help us identify risks in areas prone to strong ground shaking. These risks often include soil liquefaction, surface fault rupture and/or slope instability. Once these risks are adequately characterized we can tailor the design of the structure accordingly. For example, elevated structures that will be subject to earthquakes may be outfitted with structural damping devices to help dissipate the energy or isolation devices to allow the structure to move independently during shaking.

MediaMoguls21 karma

How small could a hyperloop scale down? Are there any interesting applications / uses cases for a sub-human-size version?

hyperloopone63 karma

we are always interested in better ways to get good tacos faster. -HD

cyrux00417 karma

  • In the current prototype you have in Nevada, what is the maximum speed you hope to achieve in your forthcoming tests (190 mph is you current max) ?

  • How hard is to maintain near vacuum air pressure across the length of the tube in a real working full length production environment ?

  • Are there longer prototypes you plan to build after Nevada, or is it straight to production system in Dubai ?

hyperloopone16 karma

Our prototype in Nevada is only a short section that we use to test the culmination of the technology we have developed. We can achieve higher speeds than what was shared in July; you have only witnessed the beginning.

It is not difficult to maintain our operating pressure. Our goal at DevLoop was to achieve 100 Pa (considered course/rough vacuum), but we have been able to get <10 Pascals! For production, there are many ways to tackle the challenges of maintaining leaks, and we are looking at all of them!

We definitely have plans to create more prototypes, rigs, and experiments! DevLoop was just the start…

-Divakar

RoyMustangela13 karma

what safety systems are in place for emergencies? How would passengers evacuate from an underground vacuum tube if the system loses power or an earthquake damages the tube?

hyperloopone15 karma

Our primary evacuation approach will be similar to aviation, getting the passengers to the nearest station or safe point as quickly as possible in emergency scenarios; similar concepts are also used by long tunnels such as Channel Tunnel, where trains try to drive through to the end of the tunnel in emergency situations. System power is a critical system and will have built-in redundancies. The tubes will be built to withstand earthquakes similar to other civil structure in the area and we will also be incorporating emergency warning system to ensure safety. I hope that answers your questions! -safety team

AwesomeSaucer912 karma

Hi, thanks so much for doing this AMA!

How do you predict hyperloop will affect urban planning and design? Will cities become more car-focused, bike/people-focused, or something else entirely?

hyperloopone12 karma

Urban planning will become regional planning as Hyperloop shrinks travel time substantially. Dense and diversified development around Hyperloop station areas. - DZ

AwesomeSaucer93 karma

Do you foresee more New Urbanist-esque design because of this?

hyperloopone8 karma

Absolutely. Hyperloop will change the concept of urban.

AwesomeSaucer93 karma

If hyperloop can reduce the dependency that cities have on roads/cars, I'm 100% for it. Best of luck!

hyperloopone7 karma

Because hyperloop is ultra-fast, on-demand, and energy efficient, hyperloop will attract car travelers, reducing congestion on highway. -DZ

Newcomer15611 karma

Do you think you can make tube pods that can hold cars? Like being able to drive my car onto then off the pod at the destination?

falconberger11 karma

How can you compete on price with 320 km/h trains? Hyperloop One seems similar to Maglevs (which are already too expensive), except it has much lower bandwidth, requires straighter lines due to the higher speed, has more serious thermal expansion issues, worse connectivity to existing transportation networks and of course there are safety issues, adding to the costs.

The advantages are speed (people willing to pay more) and maybe operating costs.

I just can't imagine the economy working out, although I hope I'm wrong. How confident are you it makes economic sense, is it more of "we've made a proper analysis, and there's a decent chance there will be market for it" or "this is a research project, we don't have exact plans for dealing with thermal expansion and safety, but let's hope it works out".

hyperloopone6 karma

All great points. Thanks for reading our analyses which were jointly conducted by consulting companies and our genius engineers. HL cost is 2/3 of high speeds rail and speed is 3x faster. Regarding the advantages of speed, HL speed will substantially improve accessibility, expand the market size, and generate huge economic benefits.

hyperloopone2 karma

Thanks for your interest! Hyperloop One system is much more energy efficient than systems such as Maglev. This results in cost reduction. Our system is going to be direct to destination which means connecting to existing modes of transportation. - SJ

falconberger2 karma

Thanks for reply, what do you mean by direct to destination?

hyperloopone8 karma

direct to destination means hyperloop one system connecting with local modes of transportation to reach to your final destination. Check this out..- SJ

SpacecadetShep10 karma

What are some of the greatest engineering challenges that your team faces?

suaveitguy9 karma

What do you think of putting the tube underground? How is it better or worse than above ground?

hyperloopone16 karma

We are definitely anticipating the need to put the tube underground. In congested urban environments there is often not another option. Tunnels have the advantage of allowing us to select more direct routes and they usually perform better in earthquakes than above-ground structures. On the negative side, they are generally more expensive and slower to construct. The choice depends on the route and the urban landscape! -BK

Check out this blog post on tunneling from our website: https://hyperloop-one.com/blog/were-living-golden-age-tunneling

joernhb8 karma

How will people be able to get on/off hyperloop without having to pressurize the whole tube? In other words: What will the stops look like?

hyperloopone6 karma

We have some pretty inventive ways to easily let people on and off without having the depressurize the whole tube. Hint: it's similar to an airlock you'd see in space.

B

Mowg9028 karma

Will all hyperloops be above ground? Or will you explore below ground options? Thinking it would be easier to go under cities then through?

hyperloopone13 karma

It is preferable to stay above ground, except when necessary in very dense urban areas. Below ground options are definitely possible; however, above ground systems are generally cheaper, faster to build, and easier to control construction, etc.

I.B.

ZiphFuture7 karma

Q1: As of now all the Hyperloop systems out there seem to be opting for a passive electrodynamic levitation system (EDS) From what I have seen at the SpaceX competition, literature and your first phase testing videos EDS seems to inherently have a lot of magnetic drag. An alternative would be to use an Electromagnetic levitation system (EMS) which Siemens used to build their transrapid maglev train (they also tried EDS at first but changed later in the development process).

While EDS might seem like a good choice at first because of its simplicity in the long term it looks like isn't the solution to go for (because of higher drag). As Siemens already proved, safety and reliability are not reasons for not choosing EMS, while it's performance is higher and it is a more integrated solution with the linear motor and also providing for power.

Have you considered using EMS and if so why did you choose to go for EDS?

Q2: Another question I have is about switching. It seems very hard to create a switching mechanism with your current suspension that would work at high frequencies of pods moving past. As it will probably require mechanical parts that need to move. Switching also seemed to be a problem at the SpaceX competition.

Can you elaborate on your plans for switches?

Q3: There is quite a lot of regulation on trains and the distance between them. What makes you think you can have vehicles at higher speeds with smaller time intervals between them? This will be required to acquire the necessary passenger flows if the vehicles are much smaller then trains.

hyperloopone11 karma

Those are fantastic questions! We would love to answer these in detail after you sign our NDA (right before your interview most likely).

What I can tell you is that we are well aware of the practical limitations of both EDS and EMS maglev. The levitation systems team at Hyperloop One has extensive experience with design and implementation of both passive and actively controlled magnetic bearings for automation and transportation. The production levitation solution will reflect this experience.

We have a solution for switching. Stay tuned.

-IU

wind_of_pain7 karma

from where you sit right now, how reasonable is it to expect it'll ever run on fully renewable energy? solar panels or something else?

hyperloopone6 karma

Hyperloop systems are all-electric, which means we can use energy from multiple sources including 100% renewable. Check out this proposed Germany route https://hyperloop-one.com/blog/worlds-fastest-highway-could-get-even-faster - DZ

AsksAStupidQuestion4 karma

Would this hyperloop technology potentially work in space? Like to move from one space station to another?

hyperloopone11 karma

One of the great challenges of Hyperloop is the infastructure to hold the pressure differential. When you are already in space, that infastructure is no longer a challenge.

-JF

CassandraVindicated3 karma

Do you realize that method of transportation has existed at the idea level for over 100 years? I remember reading about it in the 80s.

Also, what's your plan for earthquakes? I'm sure you have something but I've not read any details.

hyperloopone3 karma

There are a lot of advances in technology that make Hyperloop a viable solution now, while it may not have been feasible in the past. For example: Digital control technology, computer assisted engineering programs, advanced materials, more efficient transducers , and the use of smart phones for passengers to directly call 'on demand' transportation. -HD

sunea3 karma

do you think the hyperloop is a realistic way of transport?

hyperloopone1 karma

Absolutely! It is safe, energy efficient and faast! -SJ

Rippleman5553 karma

1) I would like to see a transparent tube. Will we see this in the future and what material would you use to construct it? Plastic?

2) If you put the hyperloop tube at an low degree angel pointing towards the sky could you launch a pod into space given enough energy?

3) Wouldn't you have saved a lot of money if you built the test track in a place where people could use it after you have finish testing? Since the test track is in the deserts now you are force to disassemble it after you are done.

4) What type of airlock are you envisioning? Are you going to simply seal of the tube let say 10 meters in and suck out the air in that section and open the seal or do have any other ideas?

hyperloopone4 karma

1) Transparent would be awesome...but more expensive compared to structural materials

2) Anything with enough energy and angle could make it to space

3) We'll be using this as an active test bed for years to come so passengers will need to wait for our first product route to grab their first ride

4) Lots of airlock types exist...that's about all I'll say.

Hydrotrex3 karma

What happens to us when we experience these enormous speeds and the breaking?

hyperloopone3 karma

We design the system to operate within the bounds of passenger comfort, drawing in part from aviation standards. Comfort means not feeling force, and inertial forces are felt by changes in velocity (acceleration) not through velocity directly. What this means for the system is we need a longer "launch" or acceleration phase to get up to our cruise speed given a lower acceleration limit.

-IU

Hydrotrex2 karma

This sounds great! Thanks for answering How do you put the "not feeling force" in effect though? Or is this implemented in the longer acceleration phase? How long do you guys think it will take until the hyperloop is a normal public transportation vehicle?

hyperloopone2 karma

We limit our propulsion acceleration to acceptable limits (limiting the force on the passenger), which then requires us to increase the time for which we need to accelerate. We are working hard to bring the hyperloop as quickly as possible! -IU

zerow3 karma

How quickly could the system get to max velocity if you were to completely ignore the passenger component (freight only transport)?

hyperloopone3 karma

Ridiculously quick.

We went from 0mph to 192mph and back to 0mph in less than 500m, and that's not even at full current!

-I.B.

hyperloopone8 karma

hyperloopone3 karma

We are also developing the alignment geometry to minimize the g-limits and jerks experienced by the passenger (in every direction).

-I.B.

Jaideco2 karma

What density of pods in a given stretch of hyperloop do you think would be achievable?

hyperloopone3 karma

As many as we can safely operate. One of the main value propositions of the Hyperloop is increased utilization of linear infrastructure as compared to traditional rail or high speed rail. We plan to minimize pod to pod spacing through a variety of techniques not available to rail, allowing us to hit our throughput requirements while using smaller pod sizes. The smaller pod sizes are required to minimize loading/unloading times and allow point to point service.

wretcheddawn2 karma

How do you respond to the criticisms presented in the videos by Thunderf00t, such as this one where he claims it's fundamentally impossible to build: https://www.youtube.com/watch?v=RNFesa01llk

What mistakes is he making?

hyperloopone2 karma

Fundamentally impossible to build? Exhibit A: https://www.youtube.com/watch?v=uLh1alyhc1E

Thunderf00t seems more intent on collecting YouTube views than engaging in real discourse about the true engineering challenges of the Hyperloop. While I would love to pick his arguments apart in detail, the shear number of basic scaling errors in his videos dwarfs the time I have left.

ErHiMate2 karma

How are you expecting to remove all the air from an extremely large tube, and it still be worth taking? doesn't it take like 8 hours or something to remove the air from like a 100m tube?

hyperloopone3 karma

How are you expecting to remove all the air from an extremely large tube, and it still be worth taking? doesn't it take like 8 hours or something to remove the air from like a 100m tube?

Thats top secret… but it doesn’t take long! Production routes will rarely be vented; once the system is at a vacuum, we use a series of pumps to maintain the required operating pressures. The only section of tubes that will be cycled on a regular basis are the airlocks. We can achieve rapid de-pressurization rates in small airlock volumes many ways… stay tuned to find out how! -DS

souvick932 karma

  1. What kind of things will be around the station in terms of land use, urban design, architecture, activity?
  2. How much is station area is required?
  3. How much fare per kilometre?
  4. How many percentage people will shift from train, plane, and bus to Hyperloop?
  5. What will be the minimum curvature of the tunnel?
  6. What will be the daily migration rate between two cities?

hyperloopone5 karma

Great questions! Many of these will depend on the route in question. Luckily our brilliant Transportation Economist, Dapeng, is running analysis on our most promising corridors to determine demand -- which in turn impacts station size, fare, and impact on other modes. As far as land use, we're excited about the ways in which a Hyperloop station can positively affect the local community, through improved accessibility and increased property values -- not to mention sheer radness*, judging by the portal design concepts our partners Bjarke Ingels Group have proposed. -- SL

*Widely accepted technical term.

souvick932 karma

I was expecting more detailed answer.

hyperloopone8 karma

Asking "what is a Hyperloop fare?" is a little like asking "what is a plane fare?" Where are you going? How far? How many people travel that route and for what purpose? The same is true for diverted demand. We have the capacity to calculate these numbers for specific origin-destination pairs, but because it's route-dependent, we can't offer a more specific answer to your question.

hyperloopone3 karma

We have developed alignment geometry where we can transition into curves from a tangent in distances less than or comparable to that of high speed rail. We have also developed the alignment geometry accompanied by banking angles to accommodate curve radii comparable to or tighter than existing high speed rail. All of our alignment geometry is constrained by passenger comfort limits. Therefore, passengers will not experience uncomfortable lateral or vertical g-forces and jerks through any curve.

-I.B.

J005HU62 karma

Would this technology overtake planes as the main mode of long distance transportation?

hyperloopone7 karma

When a huge festival happens in one city, there is music, food and good times are had by all. The number of hotels needed is directly proportional to the number of festival attendees. Hyperloop will help festival-goers to party in one city and sleep in another which will increase total hotel room availability for said festival dates. We're investigating on-demand methods to adjust pod density to areas of interest to maximize passenger throughput. MM

suaveitguy2 karma

How would rescue work in the event of being stuck in the tube?
What if the worst happened and there were collisions?

hyperloopone2 karma

We are activeliy taking a very proactive approach to avoiding collisions in the tube by putting in a lot of redundancy. The pod will have collision avoidance built into the software and hardware on the pod. It is programmed to automatically safe itself and come to a safe stop in the event of an impending collision. Secondly, our command layer - think Skynet - will be constantly watching and dynamically rescheduling pods to ensure that safety envelopes are not violated. Finally, we have put a great amount of care into the initial scheduling of pods. This will help us pro-actively schedule in a manor that should avoid collisions all together.

Congratulations on your progress!

  • How will you maintain a near vacuum in a tube that is several miles long?
  • I see no fan on the front of your pod. Is this not needed to overcome the Kantrowitz limit?
  • How will you maintain a near vacuum in the tube while people board or leave the pods? Some kind of air lock system?

Thanks,

Lasz

hyperloopone6 karma

Great questions! There are several ways to maintain leaks in a tube; one of them is to space out pumps across a route that can maintain our operating pressure. We don’t need a ton of pumps to maintain leaks, and we don’t need them very close either.

We don’t need a fan to overcome the Kantrowitz limit. We specify the required operating pressure and the cross sectional area of the tube to make sure we don’t hit this limit.

Each portal will have an airlock that is sectioned off from the rest of the tube with large gate valves. We can quickly cycle the pressure in an airlock to accommodate the loading and departure process.
