That’s set to transform our world. Meet the inventors and tech entrepreneurs who are building a new generation of extraordinary machines. IV KIER I mean no one has invented or developed this kind of technology before. Machines that promise to transform our lives IV MARS This is probably the closest you'll get to Beam me up, Scotty. Machines that will help fix our world IV BONNA I wake up everyday and look at my son and think about what it is I want his world to be like and that makes it all worth it. Step inside the workshops and test facilities of the world’s most innovative companies. ANDERS There’s a lot of people who will tell you – you are not the right guy. It turns out that every big change has to come from somebody, right? and witness these machines of tomorrow, come to life today. In the heart of Europe, engineers from the Technical University of Munich, or TUM, are making history. FELIX Ok then, you do that GABRIELE Get the ladder This is really an exciting moment. Inside this 24 metre long, 200 ton concrete tube is an invention that in time could prove to be as important as the birth of the railway or the aeroplane. FELIX There's nothing quite like this anywhere else in the world. GABRIELE So Domenik are you there? DOMINIK Turn on the main lights DOMINIK OK main lights working. Now you can turn on the pod. IV GABRIELE Some people think it's similar to a train, some other think it's similar to a plane, but actually it takes the advantages of both and combines them in a new system. If anyone can build tomorrow’s transport… UPSYNC Three, two, one…drive!…It’s Gabrielle, Felix and Domenik. UPSYNC They were in the winning team in one of the world’s most high-tech competitions held at Elon Musk’s Space X headquarters in California… …who, like the others, believes hyperloop can change the world. IV GABRIELE In order to realise Hyperloop. We don't need new physics to be discovered, so we have all the technologies that we need. But at the same time, the challenge is taking all these technologies and putting them together in an ideal way so that Hyperloop is the system we are dreaming it to be. It was Musk who first coined the phrase ‘hyperloop’ – promising a whole new form of transport that would whisk people from city to city…… or country to country…… as fast as the speed of sound. MUSK I have a name for it – its called hyperloop INTERVIEWER Hyperloop MUSK Hyperloop, yeah MUSK It goes about the average speed of twice what an aircraft would do so you go from downtown LA to downtown San Francisco in under 30 minutes IV MARS When you look at science fiction and, uh, the last stage, of course, is actually teleporting. ] This is probably the closest you'll get to, uh. Beam me up, Scotty. Yeah. This has the potential to revolutionise, not just the way we travel… But the way we live. IV ANDREA Hyperloop will have a major impact in people's life. The ability to to live in a place and work in another place that is 100km, 200km away from your home. But to achieve those dreams – in a way that helps to combat climate change – engineers face some of the biggest engineering challenges of the century. IV GABRIELE What we need is new solutions that are only provided by science and technologies to really improve the standards of living. But at the same time solving the climate crisis. 1he place to start is by solving a problem that has held back engineers for centuries: IV GABRIELE One of the challenges of designing a system that allows a pod like this one to go to speed up to 900km/h, is that we cannot use wheels, because if we would have a contact to the rail like a train would have today, we would have a lot of friction. So we need a different system to allow us to go these high speeds. Eliminating friction means eliminating all contact between the vehicle and the track. No easy task. FELIX Alright ready to Levitate in three.. two.. one And that’s exactly what Felix’s team are trying to do – by harnessing an almost magical force of nature which could finally free future transport from the wheel. FELIX So what we can see nicely here is that the air gap is changing in a regular interval. We are now varying between 8mm and 16mm. Their solution – is magnetic levitation. FELIX We have the levitation magnet, which is this black part, and we have the steel reaction rail, which is this part here. When an electric current travels around the magnet it creates a force that pulls it up towards the steel rail. When the magnet gets too close to the rail the current automatically switches off, making the magnet fall back down. But, by turning the current on and off 500 times a second the pod is suspended in mid-air! FELIX So our control system needs to maintain a constant air gap by always balancing the gravitational forces with attraction forces. Felix and the team are calculating the perfect Too narrow… and the magnet will stick to the rail. Too wide and it could become unstable. And they’ve determined it must be 10 millimetres. It works perfectly in the lab. But will this finely-tuned concept work on a 4 tonne pod in the kind of freezing cold conditions that hyperloop might one day have to operate? Sub-zero temperatures cause metal components to contract so the system could fail. FELIX Ok thank you very much, everything seems to be working! To keep an eye on the machinery, the team rig additional live-feed cameras that can be viewed in the control room. FELIX So today we're going to do something very exciting. We're going to, for the first time ever, place a camera, uh, underneath the service module to be able to monitor the levitation lift off process. And we've never done it before. FELIX So underneath I go! The magnets lie beneath the vehicle. So Felix needs to place his camera as close as possible to the action. The camera and sensors will record and measure the air gap. FELIX So at this spot here, we see the distance between the pod structure and the steel reaction rail. This distance will decrease once we turn on the levitation magnet. Ok the camera is placed nicely. Now the live feed is available at the container. Domi. Ready to levitate FELIX Yo! The cameras rigged… … but will the pod’s magnets function in such cold temperatures? GABRIELE We are getting ready to perform the test. So I just checked the camera review. Everything looks really good. As soon as FELIX is in here, we can start with the test. DOMENIK We’re a bit under pressure now but that’s where diamonds are made! FELIX All right, guys. Camera is set up. Ready to go. Let’s try levitation lift off now. DOMENIK Let’s go, Three, two, one… At first, the pod vibrates… and the gap is too big. Then the shaking stops… …and the air gap reduces from 17mm to the desired 10mm… DOMENIK So yeah you can see there's very low vibration and it's, it's super smooth even at the low temperatures. FELIX Uh, really a very smooth, almost straight curve meaning the air gap doesn't change much. That's the land now. Amazing landing as well. Well Done. Good job. The team have raised the 4-ton pod 10mm It’s enough to eliminate friction and open up the door to a whole new era of contactless travel so that one day hyperloop can glide effortlessly from city to city, whatever the conditions. Domenik So we've just successfully tested the levitation lift off in sub-zero temperatures for the first time. And yes, we've got, uh, quite a smooth lift-off and a smooth landing. In Eastern Europe, another team of hi-tech entrepreneurs also believe hyperloop can make the world a better place. BEB The climate and the planet is not going into the right direction. And I think we see it more and more every year with all this extreme weather situations. There is no other way than to solve global problems with really innovation, which has to be based on, on really creative engineering.Nevomo’s engineers also competed at Musk’s Hyperloop competitions as university students. KACPER Innovation is something that, uh, you can't acquire. This is something that you must have inside. Of course, innovation is one part, but then the hard work is actually to make your inventions happen. What Kasper and his team need to do to make hyperloop happen – is to find a new way of powering it. IV GENERALIST Until now almost all forms of land transport, what they have relied on is the contact of the wheels and then pushing off a fixed surface and that propels the vehicle forward so be that a car or a train, now that contact with that fixed surface is also what makes breaking possible. With no wheels, the team face three huge challenges: To accelerate and then brake and do it all in an energy-saving way. So the team set out to adapt an existing technology called a linear motor. It’s been used before in automated factories but never applied to a form of mass transportation. KACPER It's best imagined, uh, with an analogy of a surfer on top of the wave. So in this analogy, the vehicle is the surfer and uh, the electromagnet, uh, in the truck is creating the magnetic field that's beneath the surfer. As we want to accelerate Uh the surfer, we need to put the magnetic wave behind it so we can then push it and it accelerates. If we want to slow down our moving surfer, we need to put the wave in front of it. So then when we slow down the movement of the magnetic wave, we also slow down the movement of the surfer. If we want to maintain a constant speed we need to make sure that our surfer is directly on top on of the peak of the magnetic wave. It’s an elegant concept. But will it work in practice? KACPER So our big goal was to create a working scale model of our transportation system with the linear motor design.After running hundreds of computer simulations… …finally the big day arrives to run their working model of a linear-motor propelled hyperloop vehicle. BEN That event …. was really critical because it was for the first time ever when we were able to combine the linear motor propulsion, which is like core technology for our systems. The team must prove that the technology works, to their investors. BEN Really nervous, you know, whether it's going to work, whether or whether it's going to fly. Quite a stress. BEN We had to accelerate the vehicle to about 40, 40 something kilometres an hour on only 50 metre long test track. So that acceleration was very, very dynamic. BEN …And the braking was even more dynamic. As the pod applies the brakes, the electric motor can recuperate the energy and recharges its batteries - making the whole process more efficient… … and therefore greener. BEN There was a big applause. KACPER We've put so much work into this design. The results of the tests for the demonstrator were something that actually allow us to continue. Hyperloop is now levitated and powered up But to create a technology that will allow us to travel faster, more efficiently and emission-free in the future there are yet more obstacles for engineers to overcome. IV GENERALIST Now we’ve all stuck our hands out of a fast moving vehicle, so we know what that feels like. You can feel the push against your hand and the faster the vehicles gets – the bigger the forces are that push against it. IV GENERALIST Cars waste as much as 60% of their power simply moving air out of the way. And when we’re talking about speeds of up to 700 kilometres per hour which is the speed that hyperloop hopes to get to, then you’re using a much bigger percentage of your power just moving the air out of the way. So it is inefficient. For decades, it’s been the dream of engineers around the world to design vehicles that can eliminate air resistance.Now hyperloop engineers are on the case….…on America’s west coast - the place where dreams have always been made! California-based start-up Hyperloop Transport Technologies are determined to bring theirs to life. Their business model is to partner with high-tech engineers all over the world to innovate and make hyperloop a reality. IV SHELBY We usually say that the beautiful thing about Hyperloop is that we started with a blank sheet of paper and we created something not based on how things used to be done, but how we would like things to be done. Our office space in Los Angeles is, in an aeroplane hangar where part of the Spruce Goose was built and so imagine sitting around the table long ago talking about putting a tin can in the air and people saying, oh my gosh, that'll never happen. That's crazy! So I really feel like I get to be a part of history. ANDREA Imagine a million of particles continuously pushing against this vehicle and basically reducing the speed unless you continue pushing faster and faster with your propulsion system. Even if you make it a bullet, there is a limit you can reach in terms of maximising their dynamic shape. So to solve the problem of air resistance – these hyperloop engineers are looking to another place for inspiration. ANDREA If you go into outer space, you don't have this problem of DRAG. There we are in on in a very low pressure environment, depending on where you are in moving outside of the atmosphere of the Earth. You will reduce, little by little, the pressure. So the higher you go up in the sky, the less air resistance you get. UPSYNC NASA VOICE In space there is no air resistance at all. UPSYNC NASA VOICE You’re going to hit the ground at the same time. UPSYNC NASA VOICE How about that! This is called a vacuum – where air particles don’t exist. Hyperloop TT’s engineers can apply similar vacuum conditions by constructing giant sealed TUBES then sucking out most of the air. It’s an audacious move to bring the near-vacuum conditions of outer space down to Earth! Removing all of the air would be almost impossible – since even a microscopic leak would be game over. But engineers can remove most of it - using steel to contain the low-pressure environment. IV ANDREA Steel is a technology that it's very effective when it comes to keeping the low pressure environment. So you have a low leakage rate, meaning that you have not that many molecules from the external environment going back inside. The giant steel vacuum tubes are manufactured in segments, each 4 metres wide and 20 metres long… …and transported by truck to the test site. Finally, each piece is assembled in one long vacuum-sealed chamber, 320 metres long. IV ANDREA So we sucked the air out of the tube using a technology that is already existent in the market and is being applied in other industries and those are called vacuum pumps. These powerful pumps can remove as much as 99% of the air. This reduces the drag considerably… but at hyperloop speeds, there’s still too much air resistance. Fortunately, the team have another idea. ANDREA SYNC inside our tube, we still have some molecule of air that creates some drag resistance. So one of the strategies that we have in order to reduce the drag even more and makes the system more efficient, is to change the density of the fluid inside the tube. Hyperloop TT’s engineers are now calculating what would happen if they EXCHANGE the remaining air still inside the vacuum tubes with another gas? ANDREA SYNC You will see what happens. Moving objects slow down more in dense fluids … Helium is 7 times less dense than air… So, swapping air for helium allows pods to fly through hyperloop tubes much faster. ANDREA SYNC So this actually makes sense as it relates to the equation of the drag, which is directly proportional to the density of the liquid. And in Hyperloop TT we went even further. And we did the computer simulation to really validate this innovation, this invention. And we demonstrated how the drag force is highly reduced thanks to the reduced density of the substance inside the tube. Calculations show that a pod travelling through helium would encounter up to 85% less drag than a pod in air… …allowing hyperloop to be even faster… and more efficient. IV SHELBY It's not a train in a tube - it’s the promise of so much more. The impact on our lives could be huge. IV MARS It completely changes your perception of distance. So you could even live in another country while still being able to visit your family within an hour. Because you simply go to a Hyperloop station, you take the next vehicle going into your direction. It leaves every few minutes, so everything becomes so accessible. But if this fast, green form of transport is to move millions of people and rival short haul flights it needs to expand into a full, branching NETWORK. And this is where the next problem lies. IV GENERALIST When Elon Musk first conceived of Hyperloop – he was basically thinking of going in a single direction, going from point to point. At that time, no one had really thought about how the lines would intersect, connect or branch out and for that to happen, you have to tackle the idea of changing direction. In the remote lowlands of northern Europe one enterprising team of engineers take THE SWITCHING LANES CHALLENGE so seriously they have even added a giant BRANCH SPLIT into their test facility. TIM So we're right here in the middle of the light switch, where you can clearly see that it points to the left and to the right. And something like this on this scale. It's the only place where it's being built. TIM So I'm very driven by creating, uh, an impact and if you provide that energy sustainably to zero CO2 emissions. Uh, it really benefits humanity as a whole. Current magnetically levitating train systems –wrap their magnets around the electrified tracks. But this makes changing direction problematic. TIM They have their suspension system at the bottom of the vehicle. It needs to wrap around a beam to attract themselves upwards. And in that configuration, it's very difficult to perform relay switch. Maglev gets around this issue by shifting entire sections of track. But this won’t work for hyperloop TIM Just imagine moving whole tubes with Hyperloop and the low pressure environment. That's that's almost undoable. Instead, Tim and his team move the levitation system from the base of the vehicle to the top. Where, crucially, it simply hangs off the rail. TIM Turn on the levitation. TIM So there were four magnets on the top of the vehicle. As you can see, there are copper windings around the steel core. And by controlling the current through the copper windings, you can control the magnetic field. In theory, ‘hanging’ the pod now frees it to move in any direction as it’s no longer wrapped around a track. This leaves only one final innovation to get the pods to switch lanes. MARINUS For lane switching, here we have one of our guidance magnets, that is a very powerful uh, electromagnets that we are mounting on both. Sides of our vehicle. Four in total. And uh when we turn those magnets on, it provides a force in a sideways direction, so with that if we have them turned on one side, it will pull the vehicle, for example to the left. And that's how we lane switch. The branching test track is still not yet ready to take a pod.But Hardt have a shorter tube that can still validate the technology. There’s enough space inside for the pod to start moving left or right. TIM Live demos are always nerve-wrecking because the system has to work. It’s an ambitious test. Their radical new system is designed to simultaneously levitate a pod, and propel it forwards, while inside a vacuum tube… …and then, to make the world’s first hyperloop lane switch. ENGINEER UPSYNC Alright let’s go… Levitation in three… two… one.. and lift off! Slowly approaching out switch. Taking the switch in three… two… one.. and switch has been successfully taken. TIM It was really great and it was also sort of the key moments of this test facility to, uh, make this lane switch with our vehicle and also therefore demonstrate the first workings of a lane switch without any moving components. TUMS Back in Munich… …Gabriele and the team have not only got their levitation system up and running perfectly but their vacuum tube is now fully operational too. GABRIELE We are getting there step by step. We are solving all the issues that I think, uh, need to be solved in order for Hyperloop to become reality and actually pushing the technology to a state where it can actually be used commercially, to transport passengers. But for hyperloop to actually transport people, one factor is more important than any other: Safety. And history has taught us, it is rarely straightforward. IV GENERALIST We’ve all heard of the nightmare stories where technology was designed to work, but didn’t. You’ve got Hindenburg… you’ve got Tacoma Narrows bridge… even the first driverless cars! History is absolutely riddled with technology that didn’t quite go to plan. One of the biggest safety concerns for hyperloop are its low-pressure vacuum tubes. Most tests up till now have been unmanned. But if we’re ever going to put people into a tube where breathable air has been removed… … then engineers will need to prove it’s safe for humans. IV GENERALIST A worse case scenario is there being a breach in the pod itself. Think of a door blowing off a space craft and that would lead to a rapid depressurization of the cabin and at that point, the physics would take over and the air and everything else that’s inside the cabin would rush outside because of that pressure difference. So what can Domenik and the team do to make vacuum travel 100% safe? DOMENIK So the capsule is made of aluminium. It has to withstand the pressure difference between inside and the vacuum outside. And the biggest weak point is the door, because we have a large cut-out and we have to make sure it still holds the pressure difference. A lot of design went into this door frame to stiffen it out and the door fitting inside of it, uh, so making sure it can hold the pressure difference, but also seals it tight so no air can get out. Okay, so we'll have a little run through of the pod. So please close the pod door. RADIO Door closing. DOMENIK So now you can see the seal touching tightly being pressed at the doorframe. And that's what seals the airtight. Okay, so we close the portal. Now we're ready to leave. You'll feel a slight acceleration. More like in a train. So barely recognisable - but for a long time and that's how we get to, uh, large speeds then. PA ANNOUNCEMENT: Warning! Pod Depressurizing Warning! Pod Depressurizing….whizzing across the landscape… or even through it… But what would happen if there was a sudden breach inside the passenger pod? DOMENIK So in the very unlikely event of ceilings breaking. We have sensors in the pod detecting that way faster than a human can. Once the sensor inside the pod have detected the breach - the next stage of the safety system requires depressurizing the vacuum tube and letting in fresh air. DOMENIK Next to the Hyperloop tube. So we have our Hyperloop tube here. We also have pipes connected to the vacuum inside the tube and in case of an emergency those two butterfly valves will open and let all the air rush in to fill the tube in just some seconds. They have a very low probability of failure. And if we combine them so we have two of them, it's basically impossible for the system to fail. VOICE Releasing DOMENIK Looking good. To prove once and for all that their system is fit for human travel… …TUM perform an extraordinary test. It’s Europe’s first ever passenger ride under real vacuum conditions. FELIX The biggest milestone of this project was definitely our first passenger run. So where we actually put passengers in the pod in a vacuum condition. The whole objective of this prototype, was to be the first ones, um, to test in vacuum conditions in a full-scale Hyperloop pod. GENERALIST What they achieved was monumental – if you think of it like the first manned space flights, they knew that someone had to go in there and show the world it’s possible. FELIX As you can imagine, the build up to this test, we not only developed the whole prototype, uh and gotten ready for it, but we spent weeks and weeks on procedures and safety cases. The team test the butterfly valves Domenik checks the manual override system that can be activated to fill the chamber with air as a fallback, in case the prototypes don’t work. FELIX We made ourselves ready, and then we made it happen. With 99% of the air sucked out of the tube by the vacuum pump……the pod not only levitates but successfully runs a short distance through the 24 metre tube.And the TUM team SAFELY complete Europe’s first ever passenger ride in TRUE vacuum conditions. FELIX It felt definitely like a big relief that everything worked in the end and the team was just ecstatic. HYPERLOOP TT Passenger Experience Back in California, engineers know that for passengers to choose hyperloop over less green forms of travel… …such as planes……they will need to find it attractive and comfortable. Having no windows makes this a huge challenge. IV GENERALIST Can you imagine if we had planes, trains or even cars without any windows in? What a claustrophobic feeling it would be, that could give some people travel sickness or even lead to panic attacks and just even on the most basic human level, one of the joys of travelling is looking out of that window and seeing that change in scenery. To solve the problem of having no windows…the team are working with some of the world’s top designers to create a forward-thinking interior… using a powerful new piece of TECH kit. ANDREA Using virtual reality to experience it. It sort of was quite an organic choice. because we could find yourself in the eyes of the passenger. So do you have a 360 degrees of understanding your space, basically. The team begin by creating imaginary window frames filled in with images of passing landscapes. But left like this, these screens have a fundamental flaw that stops them looking realistic. When you look through a real vehicle window, your view changes as you move your head. So Andrea’s team have set out to find a way to make their virtual windows more convincing. ANDREA SYNC Basically what we need here is the illusion of real windows by simulating what is there called the parallax effect. To do to this – the team have designed what they call “augmented” windows. ANDREA SYNC Augmented windows is basically a combination of a monitor with a head tracking system, meaning like basically a camera that points at the head of the passenger and is able to track the movement of the head. And then the third part is like an image that is being created to simulate the movement between what it should be outside of a real window, where of course, sees its fake is recreated digitally, and the movement of the face of the passengers. With the problem of parallax solved virtual reality opens up a whole new world of possibilities. ANDREA SYNC Imagine that all of a sudden you choose a capsule where you can have a specific experience, where the capsule goes to a jungle or like in space or Mars, or in the past, in the future. And what you do, basically, you recreate inside those windows the scenery, the panorama that you will see in, in that environment. And there’s one final touch for the most claustrophobic passengers of all! ANDREA SYNC And another very interesting technology that we implemented is the skyline. So now we are representing, meaning at night. So you see, like the sky, we build the stars. But basically the strategy of this skylight is to create a very comfortable and, organic and natural environment for people to feel really, safe in, in, in an environment that is, it's, it's very natural.n less than a decade since Elon Musk first coined the phrase, these pioneering teams have brought the concept to life at lightning speed. SHELBY I think some of the naysayers thought it was crazy and science fiction. But many of the seemingly impossible challenges have been overcome. And hyperloop is closer than ever. In Poland, Nevomo are converting existing railway tracks with hyperloop levitation and propulsion systems. They see it as a stepping stone to the full hyperloop solution… Even without the tubes, they will become faster and more efficient than ever before. BEN The impacts of you know being able to travel at double the speed of existing high speed lines is going to be huge, if we can slice the travel times. And the the main advantages is that we don't have to consume any new land and we don’t have to use so many resources again. In Italy, work will soon begin on the first 10 kilometres of Europe’s first ever hyperloop route between Venice and Padua. Hyperloop TT are part of the winning consortium. ANDREA It's very exciting because it will be the first opportunity to show in the world that that, a hyperloop system actually works in basically an environment that is, is like commercial environment.If successful, the route could be extended up to 50 kilometres to join the two Italian cities, reducing travel time from a train journey of around an hour down to a few minutes. So the goal is to have these first ten kilometres up and running by 2028. And the route could also be used for transporting freight – making it even more commercially viable. And we'll have to make sure that that specific segment well integrates with the local environment and the other infrastructure that it's already existing. And finally in the Netherlands…… an ambitious infrastructure project intended to propel hyperloop into a whole new era. It’s called the SASCHA It's a 420 metre test facility of 2.5m in diameter 1,000,000kg of steel. Hardt are the driving force behind the centre… where they can test their prototypes. But their vision is for something greater: The facility is for hyperloop companies to share. Collaboration on a mammoth scale. GENERALIST Collaboration like this should absolutely be celebrated. A lot of the companies working on this began as competitors and now they’re all working together to create this genuine hyperloop community and if they are to stand any chance in creating the next form of public transport, this is exactly what’s needed. SASCHA We also feel big responsibility that what we are developing will be built for hundreds of years to come. So we want to make sure we do it right. But we also know that we cannot do this on our own. MARS To make the world a better place. We need to work together. Here, the teams aim to show governments and investors that the technology is practical and cost effective… and can be rolled out at scale across continents. SASCHA So these tubes are indeed the tubes of the hyperloop that could be built around Europe. They could also be built underground or above ground, like we have over here. So I think to build a baseline network, it would be around 10,000 kilometres, because then you can really connect to every city within Europe and across approximately three hours. MARS For a lot of people, when we show what we've already built, uh, their reaction is, oh, well, I thought it was just a concept, just an idea. TIM I really think that hyperloop will change the world. And as we look back to, um, the time now, that's where it all started. And people were looking at it critically. Will it happen? Will it not happen? But just as aeroplanes, the same happens. And I really think that in, uh, a couple of decades people look back to it in a similar way. GABRIELLE And so what we've done is build technologies and also build prototypes, capable of transporting passengers. And this is really the goal going forward, pushing the technology, um, for passenger transport. SHELBY It exists and it's real and it's happening. It's not a matter of if, it is a matter of when. And we are years away, not decades. And I'm really excited to see what will happen in the next coming years. We’ll be able to say we'll be able to point to it and say, I told you, this tin can really can go through a tube.
