A Hyperloop is a proposed high-speed mass transportation system for both passenger and freight transport. The term was invented to describe the modern open-source project. Hyperloop is described as a sealed tube or system of tubes with low air pressure through which a pod may travel substantially free of air resistance or friction. The Hyperloop could potentially move people or objects at airline speeds while being energy efficient compared with existing high-speed rail systems. This, if implemented, may reduce travel times compared to train and airplane travel over distances of under approximately 1,500 kilometres (930 miles).
It has three major components: a tube, pod, and terminal. The tube is a large sealed, low-pressure system that can be constructed above or below ground. A coach runs inside this controlled environment and is often referred to as a pod. The pod employs magnetic or aerodynamic levitation (using air-bearing skis) along with electromagnetic or aerodynamic propulsion to glide along a fixed guideway. The terminals arrivals and departures.
The Hyperloop concept has its roots in a concept invented by George Medhurst in 1799 and subsequently developed under the names pneumatic railway, atmospheric railway or vactrain. Elon Musk mentioned the Hyperloop in 2012, bringing it back to public attention. His initial concept incorporated reduced-pressure tubes in which pressurized capsules ride on air bearings driven by linear induction motors and axial compressors. The Hyperloop Alpha concept was first published in August 2013, proposing and examining a route running from the Los Angeles region to the San Francisco Bay Area, roughly following the Interstate 5 corridor. The Hyperloop Genesis paper conceived of a hyperloop system that would propel passengers along the 350-mile (560 km) route at a speed of 760 mph (1,200 km/h), allowing for a travel time of 35 minutes, which is considerably faster than current rail or air travel times. Preliminary cost estimates for this LA–SF suggested route were included in the white paper—US$6 billion for a passenger-only version, and US$7.5 billion for a somewhat larger-diameter version transporting passengers and vehicles. However, transportation analysts expressed doubts that the system could be constructed on that budget, including some predictions that the Hyperloop would be several billion dollars over budget once construction, development, and operation costs are taken into consideration.
The Hyperloop concept has been explicitly "open-sourced" by Musk and SpaceX, and others have been encouraged to take the ideas and further develop them. To that end, a few companies have been formed, and several interdisciplinary student-led teams are working to advance the technology. SpaceX built an approximately 1-kilometer-long (0.62 mi) subscale track for its pod design competition at its headquarters in Hawthorne, California. TUM Hyperloop set the world record of 463 km/h (288 mph) in July 2019 during the Hyperloop pod competition at SpaceX. Virgin Hyperloop conducted the first human trial in November 2020 at its test site in Las Vegas.
Musk first mentioned that he was thinking about a concept for a "fifth mode of transport", calling it the Hyperloop, in July 2012 at a PandoDaily event in Santa Monica, California. This hypothetical high-speed mode of transportation would have the following characteristics: immunity to weather, collision free, twice the speed of a plane, low power consumption, and energy storage for 24-hour operations. The name Hyperloop was chosen because it would go in a loop. Musk envisions the more advanced versions will be able to go at hypersonic speed. In May 2013, Musk likened the Hyperloop to a "cross between a Concorde and a railgun and an air hockey table".
From late 2012 until August 2013, a group of engineers from both Tesla and SpaceX worked on the conceptual modeling of Hyperloop. An early system design was published in the Tesla and SpaceX blogs which describes one potential design, function, pathway, and cost of a hyperloop system. According to the alpha design, pods would accelerate to cruising speed gradually using a linear electric motor and glide above their track on air bearings through tubes above ground on columns or below ground in tunnels to avoid the dangers of grade crossings. An ideal hyperloop system will be more energy-efficient, quiet, and autonomous than existing modes of mass transit. Musk has also invited feedback to "see if the people can find ways to improve it". The Hyperloop Alpha was released as an open source design. The word mark "HYPERLOOP", applicable to "high-speed transportation of goods in tubes" was issued to SpaceX on 4 April 2017.
In June 2015, SpaceX announced that it would build a 1-mile-long (1.6 km) test track to be located next to SpaceX's Hawthorne facility. The track would be used to test pod designs supplied by third parties in the competition.
By November 2015, with several commercial companies and dozens of student teams pursuing the development of Hyperloop technologies, the Wall Street Journal asserted that "The Hyperloop Movement", as some of its unaffiliated members refer to themselves, is officially bigger than the man who started it."
The MIT Hyperloop team developed the first Hyperloop pod prototype, which they unveiled at the MIT Museum on 13 May 2016. Their design uses electrodynamic suspension for levitating and eddy current braking.
On 29 January 2017, approximately one year after phase one of the Hyperloop pod competition, the MIT Hyperloop pod demonstrated the first ever low-pressure Hyperloop run in the world. Within this first competition the Delft University team from the Netherlands achieved the highest overall competition score, winning the prize for "best overall design". The award for the "fastest pod" was won by the team WARR Hyperloop from the Technical University of Munich (TUM), Germany. The team from the Massachusetts Institute of Technology (MIT) placed third overall in the competition, judged by SpaceX engineers.
The second Hyperloop pod competition took place from 25–27 August 2017. The only judging criterion was top speed, provided it was followed by successful deceleration. WARR Hyperloop from the Technical University of Munich won the competition by reaching a top speed of 324 km/h (201 mph) and therefore breaking the previous record of 310 km/h (190 mph) for Hyperloop prototypes set by Hyperloop One on their own test track.
A third Hyperloop pod competition took place in July 2018. The defending champions, the WARR Hyperloop team from the Technical University of Munich, beat their own record with a top speed of 457 km/h (284 mph) during their run.
The fourth competition in August 2019 saw the team from the Technical University of Munich, now known as TUM Hyperloop (by NEXT Prototypes e.V.), again winning the competition and beating their own record with a top speed of 463 km/h (288 mph).
The first passenger test of Hyperloop technology was successfully conducted by Virgin Hyperloop with two employees of the company in November 2020.
Theory and operation
Developments in high-speed rail have historically been impeded by the difficulties in managing friction and air resistance, both of which become substantial when vehicles approach high speeds. The vactrain concept theoretically eliminates these obstacles by employing magnetically levitating trains in evacuated (airless) or partly evacuated tubes, allowing for speeds of thousands of kilometers per hour. However, the high cost of maglev and the difficulty of maintaining a vacuum over large distances has prevented this type of system from ever being built. The Hyperloop resembles a vactrain system but operates at approximately one millibar (100 Pa) of pressure.
Initial design concept
The Hyperloop concept operates by sending specially designed "capsules" or "pods" through a steel tube maintained at a partial vacuum. In Musk's original concept, each capsule floats on a 0.02–0.05 in (0.5–1.3 mm) layer of air provided under pressure to air-caster "skis", similar to how pucks are levitated above an air hockey table, while still allowing higher speeds than wheels can sustain. Hyperloop One's technology uses passive maglev for the same purpose. Linear induction motors located along the tube would accelerate and decelerate the capsule to the appropriate speed for each section of the tube route. With rolling resistance eliminated and air resistance greatly reduced, the capsules can glide for the bulk of the journey. In Musk's original Hyperloop concept, an electrically driven inlet fan and axial compressor would be placed at the nose of the capsule to "actively transfer high-pressure air from the front to the rear of the vessel", resolving the problem of air pressure building in front of the vehicle, slowing it down. A fraction of the air is shunted to the skis for additional pressure, augmenting that gain passively from lift due to their shape. Hyperloop One's system does away with the compressor.
In the alpha-level concept, passenger-only pods are to be 7 ft 4 in (2.23 m) in diameter and are projected to reach a top speed of 760 mph (1,220 km/h) to maintain aerodynamic efficiency. (Section 4.4) The design proposes passengers experience a maximum inertial acceleration of 0.5 g, about 2 or 3 times that of a commercial airliner on takeoff and landing.
A number of routes have been proposed for Hyperloop systems that meet the approximate distance conditions for which a Hyperloop is hypothesized to provide improved transport times (distances of under approximately 1,500 kilometres (930 miles)). Route proposals range from speculation described in company releases to business cases to signed agreements.
- United States
- The route suggested in the 2013 alpha-level design document was from the Greater Los Angeles Area to the San Francisco Bay Area. That conceptual system would begin around Sylmar, just south of the Tejon Pass, follow Interstate 5 to the north, and arrive near Hayward on the east side of San Francisco Bay. Several proposed branches were also shown in the design document, including Sacramento, Anaheim, San Diego, and Las Vegas.
- No work has been done on the route proposed in Musk's alpha-design; one cited reason is that it would terminate on the fringes of the two major metropolitan areas (Los Angeles and San Francisco), resulting in significant cost savings in construction, but requiring that passengers traveling to and from Downtown Los Angeles and San Francisco, and any other community beyond Sylmar and Hayward, to transfer to another transportation mode in order to reach their final destination. This would significantly lengthen the total travel time to those destinations.
- A similar problem already affects present-day air travel, where on short routes (like LAX-SFO) the flight time is only a rather small part of door to door travel time. Critics have argued that this would significantly reduce the proposed cost and/or time savings of Hyperloop as compared to the California High-Speed Rail project that will serve downtown stations in both San Francisco and Los Angeles. Passengers travelling from financial center to financial center are estimated to save about two hours by taking the Hyperloop instead of driving the whole distance.
- Others questioned the cost projections for the suggested California route. Some transportation engineers argued in 2013 that they found the alpha-level design cost estimates unrealistically low given the scale of construction and reliance on unproven technology. The technological and economic feasibility of the idea is unproven and a subject of significant debate.
- Virgin Hyperloop One is actively pursuing a hyperloop route in Texas that would run along the I-35 corridor from the Dallas-Fort Worth Metroplex southward through Austin and San Antonio before terminating at Laredo.
- In November 2017, Arrivo announced a plan for a maglev automobile transport system from Aurora, Colorado to Denver International Airport, the first leg of a system from downtown Denver. Its contract describes completion of the first leg in 2021. In February 2018, Hyperloop Transportation Technologies announced a similar plan for a loop connecting Chicago and Cleveland and a loop connecting Washington and New York City.
- In 2018 the Missouri Hyperloop Coalition was formed between Virgin Hyperloop One, the University of Missouri, and engineering firm Black & Veatch to study a proposed route connecting St. Louis, Columbia, and Kansas City.
- On 19 December 2018, Elon Musk unveiled a 2-mile (3 km) tunnel below Los Angeles. In the presentation, a Tesla Model X drove in a tunnel on the predefined track (rather than in a low-pressure tube). According to Musk the costs for the system are US$10 million. Musk said: "The Loop is a stepping stone toward Hyperloop. The Loop is for transport within a city. Hyperloop is for transport between cities, and that would go much faster than 150 mph."
- The Northeast Ohio Areawide Coordinating Agency, or NOACA, has partnered with Hyperloop Transportation Technologies to conduct a $1.3 million feasibility study for developing a Hyperloop corridor route from Chicago to Cleveland and Pittsburgh for America's first multistate hyperloop system in the Great Lakes Megaregion. Hundreds of thousands of dollars already have been committed to the project. NOACA's Board of Directors has awarded a $550,029 contract to Transportation Economics & Management Systems, Inc. (TEMS) for the Great Lakes Hyperloop Feasibility Study to evaluate the feasibility of an ultra-high-speed Hyperloop passenger and freight transport system initially linking Cleveland and Chicago.
- Hyperloop Transportation Technologies are in process to sign a Letter of Intent with the Indian Government for a proposed route between Chennai and Bengaluru. If things go as planned, the distance of 345 km could be covered in 30 minutes. HTT also signed an agreement with Andhra Pradesh government to build India's first Hyperloop project connecting Amaravathi to Vijayawada in a 6-minute ride.
- On 22 February 2018, Hyperloop One has entered into a MOU (Memorandum of Understanding) with the Government of Maharashtra to build a hyperloop transportation system between Mumbai and Pune that would cut the travel time from the current 180 minutes to just 20 minutes.
- Indore-based Dinclix GroundWorks' DGWHyperloop advocates a Hyperloop corridor between Mumbai and Delhi, via Indore, Kota, and Jaipur.
- Many of the active Hyperloop routes being planned currently are outside of the U.S. Hyperloop One published the world's first detailed business case for a 300-mile (500 km) route between Helsinki and Stockholm, which would tunnel under the Baltic Sea to connect the two capitals in under 30 minutes. Hyperloop One is also well underway on a feasibility study with DP World to move containers from its Port of Jebel Ali in Dubai. Hyperloop One on 8 November 2016, announced a new feasibility study with Dubai's Roads and Transport Authority for passenger and freight routes connecting Dubai with the greater United Arab Emirates. Hyperloop One is also working on passenger routes in Moscow and a cargo Hyperloop to connect Hunchun in north-eastern China to the Port of Zarubino, near Vladivostok and the North Korean border on Russia's Far East. In May 2016, Hyperloop One kicked off their Global Challenge with a call for comprehensive proposals of hyperloop networks around the world. In September 2017, Hyperloop One selected 10 routes from 35 of the strongest proposals: Toronto–Montreal, Cheyenne–Denver–Pueblo, Miami–Orlando, Dallas–Laredo–Houston, Chicago–Columbus–Pittsburgh, Mexico City–Guadalajara, Edinburgh–London, Glasgow–Liverpool, Bengaluru–Chennai, and Mumbai–Chennai.
- Others have put forward European routes, including a route beginning at Amsterdam or Schiphol to Frankfurt proposed by Hardt Hyperloop. A Warsaw University of Technology team is evaluating potential routes from Cracow to Gdańsk across Poland proposed by Hyper Poland.
- TransPod is exploring the possibility of Hyperloop routes which would connect Toronto and Montreal, Toronto to Windsor, and Calgary to Edmonton. Toronto and Montreal, the largest cities in Canada, are currently connected by Ontario Highway 401, the busiest highway in North America. In March 2019, Transport Canada commissioned the study of the Hyperloop, so it can be “better informed on the technical, operational, economic, safety, and regulatory aspects of the Hyperloop and understand its construction requirements and commercial feasibility.”
- Hyperloop Transportation Technologies (HTT) reportedly signed an agreement with the government of Slovakia in March 2016 to perform impact studies, with potential links between Bratislava, Vienna, and Budapest, but there have been no developments on that since. In January 2017, HTT signed an agreement to explore the route Bratislava—Brno—Prague in Central Europe.
- In 2017, SINTEF, the largest independent research organization in Scandinavia, announced they are considering building a test lab for Hyperloop in Norway.
- An agreement was signed in June 2017 to co-develop a hyperloop line between Seoul and Busan in South Korea.
Open-source design evolution
In September 2013, Ansys Corporation ran computational fluid dynamics simulations to model the aerodynamics of the capsule and shear stress forces that the capsule would be subjected to. The simulation showed that the capsule design would need to be significantly reshaped to avoid creating supersonic airflow, and that the gap between the tube wall and capsule would need to be larger. Ansys employee Sandeep Sovani said the simulation showed that Hyperloop has challenges but that he is convinced it is feasible.
In October 2013, the development team of the OpenMDAO software framework released an unfinished, conceptual open-source model of parts of the Hyperloop's propulsion system. The team asserted that the model demonstrated the concept's feasibility, although the tube would need to be 13 feet (4 m) in diameter, significantly larger than originally projected. However, the team's model is not a true working model of the propulsion system, as it did not account for a wide range of technical factors required to physically construct a Hyperloop based on Musk's concept, and in particular had no significant estimations of component weight.
In November 2013, MathWorks analyzed the proposal's suggested route and concluded that the route was mainly feasible. The analysis focused on the acceleration experienced by passengers and the necessary deviations from public roads in order to keep the accelerations reasonable; it did highlight that maintaining a trajectory along I-580 east of San Francisco at the planned speeds was not possible without significant deviation into heavily populated areas.
In January 2015, a paper based on the NASA OpenMDAO open-source model reiterated the need for a larger diameter tube and a reduced cruise speed closer to Mach 0.85. It recommended removing on-board heat exchangers based on thermal models of the interactions between the compressor cycle, tube, and ambient environment. The compression cycle would only contribute 5% of the heat added to the tube, with 95% of the heat attributed to radiation and convection into the tube. The weight and volume penalty of on-board heat exchangers would not be worth the minor benefit, and regardless the steady-state temperature in the tube would only reach 30–40 °F (17–22 °C) above ambient temperature.
Researchers associated with MIT's department of Aeronautics and Astronautics published research in June 2017 that verified the challenge of aerodynamic design near the Kantrowitz limit that had been theorized in the original SpaceX Alpha-design concept released in 2013.
In February 2020, Hardt Hyperloop, Hyper Poland, TransPod and Zeleros formed a consortium to drive standardisation efforts, as part of a joint technical committee (JTC20) set up by European standards bodies CEN and CENELEC to develop common standards aimed at ensuring the safety and interoperability of infrastructure, rolling stock, signalling and other systems.
According to Musk, Hyperloop would be useful on Mars as no tubes would be needed because Mars' atmosphere is about 1% the density of the Earth's at sea level. For the Hyperloop concept to work on Earth, low-pressure tubes are required to reduce air resistance. However, if they were to be built on Mars, the lower air resistance would allow a Hyperloop to be created with no tube, only a track. This type of transportation infrastructure is commonly referred to as a train.
Virgin Hyperloop (formerly Hyperloop One, Virgin Hyperloop One, and before that, Hyperloop Technologies) was incorporated in 2014 and has built a team of 280+,[when?] including engineers, technicians, welders, and machinists. It has raised more than US$160 million in capital from investors including DP World, Sherpa Capital, Formation 8, 137 Ventures, Caspian Venture Capital, Fast Digital, GE Ventures, and SNCF.
Hyperloop One was founded by Shervin Pishevar and Brogan BamBrogan. BamBrogan left the company in July 2016, along with three of the other founding members of Arrivo. Hyperloop One then selected co-founder Josh Giegel, a former SpaceX engineer, to be CTO; Giegel now serves as CEO.
Hyperloop One has a 75,000-square foot Innovation Campus in downtown LA and a 100,000-square foot machine and tooling shop in North Las Vegas. By 2017, it had completed a 500m Development Loop (DevLoop) in North Las Vegas, Nevada.
On 11 May 2016, Hyperloop One conducted the first live trial of Hyperloop technology, demonstrating that its custom linear electric motor could propel a sled from 0 to 110 miles an hour in just over one second. The acceleration exerted approximately 2.5 g on the sled. The sled was stopped at the end of the test by hitting a pile of sand at the end of the track, because the test was not intended to test braking components.
In July 2016, Hyperloop One released a preliminary study that suggested a Hyperloop connection between Helsinki and Stockholm would be feasible, reducing the travel time between the cities to half an hour. The construction costs were estimated by Hyperloop One to be around €19 billion (US$21 billion at 2016 exchange rates).
In August 2016, Hyperloop One announced a deal with the world's third largest ports operator, DP World, to develop a cargo offloader system at DP World's flagship port of Jebel Ali in Dubai. Hyperloop One also broke ground on DevLoop, its full-scale Hyperloop test track.
In November 2016, Hyperloop One disclosed that it has established a high-level working group relationship with the governments of Finland and the Netherlands to study the viability of building Hyperloop proof of operations centers in those countries. Hyperloop One also has a feasibility study underway with Dubai's Roads and Transport Authority for passenger systems in the UAE. Other feasibility studies are underway in Russia, Los Angeles, and the Netherlands.
On 12 May 2017, Hyperloop One performed its first full-scale Hyperloop test, becoming the first company in the world to test a full-scale Hyperloop. The system-wide test integrated Hyperloop components including vacuum, propulsion, levitation, sled, control systems, tube, and structures.
On 12 July 2017, the company revealed images of its first-generation pod prototype, which will be used at the DevLoop test site in Nevada to test aerodynamics.
On 12 October 2017, the company received a "significant investment" from the Virgin Group founder Richard Branson, leading to a rebrand of the name.
In March 2019, Missouri governor Mike Parson announced the creation of a "Blue Ribbon" panel to examine the specifics of funding and construction of the Missouri Hyperloop. The route would connect Missouri's largest cites including St. Louis, Kansas City, and Columbia. This comes after a 2018 feasibility study found the route viable, the first such study in the United States.
In July 2019, the Government of Maharashtra State of India and Hyperloop One set a target to create the first hyperloop system in the world between Pune and Mumbai.
In November 2020, Company co-founder Josh Giegel and head of Passenger Experience Sara Luchian were part of the first crewed Hyperloop trip on the company's DevLoop in Nevada, reaching a speed of 172 km/h (107 mph).
Hyperloop Transportation Technologies
Hyperloop Transportation Technologies (HTT) is the first Hyperloop company created (founded in 2013), with a current workforce of more than 800 engineers and professionals located around the world. Some collaborate part-time; others are full-time employees and contributors. Some members are full-time paid employees; others work in exchange for salary and stock options.
After Musk's Hyperloop concept proposal in 2012, Jumpstarter, Inc founder Dirk Ahlborn placed a 'call to action' on his Jumpstarter platform. Jumpstarter started pooling resources and amassed 420 people to the team.
HTT announced in May 2015 that a deal had been finalized with landowners to build a 5-mile (8 km) test track along a stretch of road near Interstate 5 between Los Angeles and San Francisco. In December 2016, Hyperloop Transportation Technologies and the government of Abu Dhabi announced plans to conduct a feasibility study on a Hyperloop link between the UAE capital and Al Ain, reducing travel time between Abu Dhabi and Al Ain to just under 10-minutes. In September 2017, HTT announced and signed an agreement with the Andhra Pradesh state government of India to build a track from Amaravathi to Vijayawada in a public-private partnership, and suggested that the more than one hour trip could be reduced to 5 minutes through the project. For yet undisclosed reason, neither the test track that HTT announced in May 2015 nor any other test track has been built in the last 3 years.
In June 2018, Ukraine's Infrastructure Ministry reached an agreement with Hyperloop Transportation Technologies to develop its high-speed vacuum transport technology in Ukraine. According to minister, Volodymyr Omelyan, a joint research and development center will be created in Kyiv or Dnipro, which will not only work on Hyperloop but new “materials and components for modern transportation systems.”
Later in 2018, the company signed an agreement with the Guizhou province of China to build a Hyperloop. In its China deal, HTT will provide technology, engineering expertise, and essential equipment in the venture, while Tongren will take charge of relevant certifications, regulatory framework, and construction of the system, the press release said. The venture will be a public private partnership in which 50 percent of the funds will come directly from Tongren, it added.
In May 2019, the company and TÜV SÜD presented the EU with generic guidelines for hyperloop design, operation and certification. In June 2019,Hyperloop Transportation Technologies met with officials from the United States Department of Transportation, USDOT, at HyperloopTT's research facilities in Toulouse, France. Simultaneously, other members of HyperloopTT met with the USDOT at the agency's offices in Washington D.C. presenting a technical overview of Hyperloop technology and the certification guideline completed by TÜV SÜD.
HyperloopTT is now beginning the process of integrating their full-scale passenger capsule for human trials in 2020.
TransPod Inc. is a Canadian company designing and manufacturing ultra-high-speed tube transportation technology and vehicles. In November 2016 TransPod raised a US$15 million seed round from Angelo Investments, an Italian high-tech holding group, specializing in advanced technologies for the railway, space, and aviation industries.
In September 2017, TransPod released a scientific peer-reviewed publication in the journal Procedia Engineering. The paper was premiered at the EASD EURODYN 2017 conference, and presents the physics of the TransPod system.
TransPod vehicles are being designed to travel at over 1,000 km/h between cities using fully electric propulsion and zero need for fossil fuels. The TransPod tube system is distinct from the hyperloop concept proposed by Elon Musk's Hyperloop Alpha white paper. The TransPod system uses moving electromagnetic fields to propel the vehicles with stable levitation off the bottom surface, rather than compressed air. TransPod is stated to contain further developments beyond hyperloop. To achieve fossil-fuel-free propulsion, TransPod "pods" take advantage of electrically driven linear induction motor technology, with active real-time control and sense-space systems. The cargo transport TransPod pods will be able to carry payloads of 10–15 tons and have compatibility with wooden pallets, as well as various unit load devices such as LD3 containers, and AAA containers.
At the InnoTrans Rail Show 2016 in Berlin, TransPod premiered their vehicle concept, alongside implementation of Coelux technology—an artificial skylight to emulate natural sunlight within the passenger pods.
TransPod has partnered with investor Angelo Investments' member companies MERMEC, SITAEL, and Blackshape Aircraft. With international staff of over 1,000 employees, 650 of whom are engineers, they will collaborate with the development and testing of the TransPod tube system It has since expanded from its Toronto, Canada headquarters at MaRS Discovery District to open offices in Toulouse, France and Bari, Italy. TransPod is additionally partnered with university researchers, engineering firm IKOS, REC Architecture and Liebherr-Aerospace.
TransPod is developing routes worldwide and in Canada such as Toronto-Montreal, Toronto-Windsor, and Calgary-Edmonton. TransPod is preparing to build a test track for the pod vehicles in Canada. This track will be extendable as part of a full route pending a combination of private and public funding to construct the line.
In July 2017, TransPod released an initial cost study which outlines the viability of building a hyperloop line in Southwestern Ontario between the cities of Windsor and Toronto. The study indicates a TransPod tube system would cost half the projected cost of a high-speed rail line along the same route, while operating at more than four times the top speed of high speed rail.
TransPod has announced plans for a test track to be constructed in the town of Droux near Limoges in collaboration with the French department of Haute-Vienne. The proposed test track would exceed 3 km in length, and operate as a half-scale system 2 m in diameter. In February 2018 Vincent Leonie, vice president of Limoges Métropole and a deputy mayor of Limoges, has announced agreements for the "Hyperloop Limoges" organization have been signed to promote and accelerate the technology.
Established in 2015, DGWHyperloop is a subsidiary of Dinclix GroundWorks, an engineering company based in Indore, India. DGWHyperloop's initial proposals include a Hyperloop-based corridor between Delhi and Mumbai called the Delhi Mumbai Hyperloop Corridor (DMHC). The company has partnered with many government agencies, private companies, and institutions for its research on Hyperloop. DGWHyperloop is the only Indian company working on implementing the Hyperloop system across the nation.
Arrivo was a technology architecture and engineering company founded in Los Angeles in 2016. In November 2017, it disclosed a plan to build a 200 mph (320 km/h) link for automobiles to Denver International Airport using maglev train technology by 2021. On 14 December 2018 Technology news site The Verge reported Arrivo was shutting down, due to being unable to secure Series A funding.
On 17 October 2019, The Verge reported the Intellectual Property from Arrivo was purchased by rLoop, a reddit-born engineering group.
Hardt Global Mobility
The Dutch team is setting up a full-scale testing center for hyperloop technology in Delft. Hardt has received over €600,000 in funding for the initial rounds of testing, with plans to raise more to build a high-speed test line by 2019. At the unveiling of the test track, Dutch Minister of Infrastructure and Environment Schultz van Haegen said a Hyperloop system could help cement the Netherlands' position as a gateway to Europe by transporting freight arriving at Rotterdam's sprawling port.
On 9 October 2017 a report was released with information from Hardt Global Mobility and Hyperloop One. The report has been sent to the Dutch House of Representatives and judges the added value of a hyperloop test track facility. The report recommends building a test track of 5 km in Flevoland.
Zeleros was founded in Valencia (Spain) in November 2016 by Daniel Orient (CTO), David Pistoni (CEO) and Juan Vicén (CMO), former leaders of the Hyperloop UPV team from Universitat Politècnica de València. The team was awarded "Top Design Concept" and "Propulsion/Compression Subsystem Technical Excellence" at SpaceX's Hyperloop Design Weekend, the first phase of the Hyperloop Pod Competition conducted at Texas A&M University on 29–30 January 2016. After building Spain's first Hyperloop prototype with the support of Purdue University and building a 12-meter research test-track in Spain at the university, the company was awarded in November 2017 the international Everis Foundation prize. Zeleros has the support of the Silicon Valley accelerator Plug and Play Tech Center, its partner Alberto Gutierrez, (partner of Plug and Play Spain and founder of Aqua Service), and the Spanish venture capital fund Angels Capital owned by the Spanish businessman Juan Roig, owner of Mercadona. By June 2018, the corporation signed an agreement with the rest of the Hyperloop European companies (Hyper Poland and Hardt) and the Canadian TransPod to collaborate with the European Union and other international institutions for the implementation of a definition of the standards to ensure the interoperability and the security of a Hyperloop. In August 2018, Zeleros held a meeting with Pedro Duque, the ministry of science to push for his support of the European initiative. By September 2018, the corporation announced the construction of a 2 km test track to perform dynamic tests of the system. The test track will be allocated in Sagunto in 2019 with the support of the Sagunto council and the Generalitat Valenciana. In November 2018, Zeleros received the international award in the World Transport Congress in Mascate, Omán. By February 2019, the corporation was formed by a team of 20 engineers and doctors specialized in different fields, developing and testing the systems and subsystems of the Hyperloop integrators.
In June 2020 Zeleros raised more than €7 million in financing, with plans to use them in the development of its core technologies, the construction of a European Hyperloop Development Centre in Spain and building a 3 km test track.
Their designs are said to incorporate an on-board maglev levitation and linear electric motor propulsion rather than in-track inductors coupled with pneumatic tube thrust motors, together allegedly capable of achieving one thousand Km/h (≈620 MPH). The ultimate intention is to combine both intermodal container and passenger compartments that will exploit advanced aircraft technology.
Nevomo (previously Hyper Poland)
Nevomo (until November 2020 Hyper Poland) is a Polish company founded in 2017 by Przemysław Pączek, Katarzyna Foljanty, Paweł Radziszewski and Łukasz Mielczarek, mostly graduates from the Warsaw University of Technology. In the summer of 2017, acting as the Hyper Poland University Team, they built a hyperloop vehicle model which took part in the SpaceX Pod Competition II in California. In March 2018, the company was recognized as one of the best startups in the mobility sector in Europe.
Unlike other companies in the Hyperloop sector, Nevomo develops a system aimed at offering a low-cost upgrade to existing conventional railway corridors. The system - dubbed ‘magrail’ - is based on magnetic levitation, linear motor and autonomous control systems and can be transformed into a full-fledged, vacuum Hyperloop at a later stage.
Key differentiator of Nevomo's magrail technology is its interoperability with conventional railway systems which allows for the functionality of both the magrail system and conventional trains on the same tracks and promises reduced infrastructure costs and faster implementation by using existing and regulatorily approved railway corridors. In its initial implementation stage, the system is designed for speeds comparable to today's conventional high-speed rail (300–415 km/h), but at significantly lower implementation costs. The system allows a subsequent upgrade into a vacuum system with speeds of up to 600 km/h on conventional tracks and 1,000 km/h on HSR lines.
In the first half of 2019, Nevomo secured a EUR 3.8 million grant from the Polish National Center for Research and Development and two pre-seed rounds on a UK equity crowdfunding platform of EUR 820k total.
In October 2019, Nevomo presented its 'magrail' prototype vehicle and a track in 1:5 scale. Nevomo has completed the first magrail tests on a medium-sized track and plans to start full-scale tests in mid-2021.
In June 2021 Nevomo signed a memorandum of understanding with Rete Ferroviaria Italiana (RFI) to collaborate on studies to verify the technical and economic feasibility of superposing magrail technology. The two firms will apply to the European Union for funding to built a full-scale system pilot on a test track at the Bologna San Donato railway test circuit, which is owned by RFI.
Hyperloop research programs
TUM Hyperloop (previously WARR Hyperloop)
TUM Hyperloop is a research program that emerged in 2019 from the team of Hyperloop pod competition from the Technical University of Munich. The TUM Hyperloop team had won all four competitions in a row, achieving the world record of 463 km/h (288 mph), which is still valid today. The research program has the goals to investigate the technical feasibility by means of a demonstrator, as well as by simulation the economic and technical feasibility of the Hyperloop system. The planned 24m demonstrator will consist of a tube and the full-size pod. The next steps after completion of the first project phase are the extension to 400m to investigate higher speeds. This is planned in the Munich area, in Taufkirchen, Ottobrunn or at the Oberpfaffenhofen airfield.
EuroTube is a non-profit research organization for the development of vacuum transport technology. EuroTube is currently developing a 3.1 km test tube in Collombey-Muraz, Switzerland. The organization was founded in 2017 at ETH Zurich as a Swiss association and became a Swiss foundation in 2019. The test tube is planned on a 2:1 scale with a diameter of 2.2 m and designed for 900 km/h (560 mph).
Hyperloop pod competition
A number of student and non-student teams were participating in a Hyperloop pod competition in 2015–16, and at least 22 of them built hardware to compete on a sponsored hyperloop test track in mid-2016.
In June 2015, SpaceX announced that they would sponsor a Hyperloop pod design competition, and would build a 1-mile-long (1.6 km) subscale test track near SpaceX's headquarters in Hawthorne, California, for the competitive event in 2016. SpaceX stated in their announcement, "Neither SpaceX nor Elon Musk is affiliated with any Hyperloop companies. While we are not developing a commercial Hyperloop ourselves, we are interested in helping to accelerate development of a functional Hyperloop prototype."
More than 700 teams had submitted preliminary applications by July, and detailed competition rules were released in August. Intent to Compete submissions were due in September 2015 with more detailed tube and technical specification released by SpaceX in October. A preliminary design briefing was held in November 2015, where more than 120 student engineering teams were selected to submit Final Design Packages due by 13 January 2016.
A Design Weekend was held at Texas A&M University 29–30 January 2016, for all invited entrants. Engineers from the Massachusetts Institute of Technology were named the winners of the competition. While the University of Washington team won the Safety Subsystem Award, Delft University won the Pod Innovation Award as well as the second place, followed by the University of Wisconsin–Madison, Virginia Tech, and the University of California, Irvine. In the Design Category, the winner team was Hyperloop UPV from Universitat Politecnica de Valencia, Spain. On 29 January 2017, Delft Hyperloop (Delft University of Technology) won the prize for the "best overall design" at the final stage of the SpaceX Hyperloop competition, while WARR Hyperloop of the Technical University of Munich won the prize for "fastest pod". The Massachusetts Institute of Technology placed third.
The second Hyperloop pod competition took place from 25–27 August 2017. The only judging criteria being top speed provided it is followed by successful deceleration. WARR Hyperloop from the Technical University of Munich won the competition by reaching a top speed of 324 km/h (201 mph).
A third Hyperloop pod competition took place in July 2018. The defending champions, the WARR Hyperloop team from the Technical University of Munich, beat their own record with a top speed of 457 km/h (284 mph) during their run. The fourth competition in August 2019 saw the team from the Technical University of Munich, now known as TUM Hyperloop (by NEXT Prototypes e.V.), again winning the competition and beating their own record with a top speed of 463 km/h (288 mph).
Criticism and human factor considerations
Some critics of Hyperloop focus on the experience—possibly unpleasant and frightening—of riding in a narrow, sealed, windowless capsule inside a sealed steel tunnel, that is subjected to significant acceleration forces; high noise levels due to air being compressed and ducted around the capsule at near-sonic speeds; and the vibration and jostling. Even if the tube is initially smooth, ground may shift with seismic activity. At high speeds, even minor deviations from a straight path may add considerable buffeting. This is in addition to practical and logistical questions regarding how to best deal with safety issues such as equipment malfunction, accidents, and emergency evacuations.
Other maglev trains are already in use, which avoid much of the added costs of Hyperloop. The SCMaglev in Japan has demonstrated 603 km/h (375 mph) without a vacuum tube, by using an extremely aerodynamic train design. It also avoids the cost and time required to pressurize and depressurize the exit and entry points of a Hyperloop tube.
There is also the criticism of design technicalities in the tube system. John Hansman, professor of aeronautics and astronautics at MIT, has stated problems, such as how a slight misalignment in the tube would be compensated for and the potential interplay between the air cushion and the low-pressure air. He has also questioned what would happen if the power were to go out when the pod was miles away from a city. UC Berkeley physics professor Richard Muller has also expressed concern regarding "[the Hyperloop's] novelty and the vulnerability of its tubes, [which] would be a tempting target for terrorists", and that the system could be disrupted by everyday dirt and grime.
Political and economic considerations
The alpha proposal projected that cost savings compared with conventional rail would come from a combination of several factors. The small profile and elevated nature of the alpha route would enable Hyperloop to be constructed primarily in the median of Interstate 5. However, whether this would be truly feasible is a matter of debate. The low profile would reduce tunnel boring requirements and the light weight of the capsules is projected to reduce construction costs over conventional passenger rail. It was asserted that there would be less right-of-way opposition and environmental impact as well due to its small, sealed, elevated profile versus that of a rail easement; however, other commentators contend that a smaller footprint does not guarantee less opposition. In criticizing this assumption, mass transportation writer Alon Levy said, "In reality, an all-elevated system (which is what Musk proposes with the Hyperloop) is a bug rather than a feature. Central Valley land is cheap; pylons are expensive, as can be readily seen by the costs of elevated highways and trains all over the world". Michael Anderson, a professor of agricultural and resource economics at UC Berkeley, predicted that costs would amount to around US$100 billion.
The Hyperloop white paper suggests that US$20 of each one-way passenger ticket between Los Angeles and San Francisco would be sufficient to cover initial capital costs, based on amortizing the cost of Hyperloop over 20 years with ridership projections of 7.4 million per year in each direction and does not include operating costs (although the proposal asserts that electric costs would be covered by solar panels). No total ticket price was suggested in the alpha design. The projected ticket price has been questioned by Dan Sperling, director of the Institute of Transportation Studies at UC Davis, who stated that "there's no way the economics on that would ever work out." However, some critics have argued that, being designed to carry fewer passengers than typical public train systems, it could make it difficult to price tickets to cover the costs of construction and running.
The early cost estimates of the Hyperloop are a subject of debate. A number of economists and transportation experts have expressed the belief that the US$6 billion price tag dramatically understates the cost of designing, developing, constructing, and testing an all-new form of transportation. The Economist said that the estimates are unlikely to "be immune to the hypertrophication of cost that every other grand infrastructure project seems doomed to suffer."
Political impediments to the construction of such a project in California will be very large. There is a great deal of "political and reputation capital" invested in the existing mega-project of California High-Speed Rail. Replacing that with a different design would not be straightforward given California's political economy. Texas has been suggested as an alternate for its more amenable political and economic environment.
Building a successful Hyperloop sub-scale demonstration project could reduce the political impediments and improve cost estimates. Musk has suggested that he may be personally involved in building a demonstration prototype of the Hyperloop concept, including funding the development effort.
The solar panels Musk plans to install along the length of the Hyperloop system have been criticized by engineering professor Roger Goodall of Loughborough University, as not being feasible enough to return enough energy to power the Hyperloop system, arguing that the air pumps and propulsion would require much more power than the solar panels could generate.
The concept of transportation of passengers in pneumatic tubes is not new. The first patent to transport goods in tubes was taken out in 1799 by the British mechanical engineer and inventor George Medhurst. In 1812, Medhurst wrote a book detailing his idea of transporting passengers and goods through air-tight tubes using air propulsion.
In the early 1800s, there were other similar systems proposed or experimented with and were generally known as an atmospheric railway although this term is also used for systems where the propulsion is provided by a separate pneumatic tube to the train tunnel itself.
One of the earliest was the Dalkey Atmospheric Railway which operated near Dublin between 1844 and 1854.
The Crystal Palace pneumatic railway operated in London around 1864 and used large fans, some 22 ft (6.7 m) in diameter, that were powered by a steam engine. The tunnels are now lost but the line operated successfully for over a year.
Operated from 1870 to 1873, the Beach Pneumatic Transit was a one-block-long prototype of an underground tube transport public transit system in New York City. The system worked at near-atmospheric pressure, and the passenger car moved by means of higher-pressure air applied to the back of the car while somewhat lower pressure was maintained on the front of the car.
In the 1910s, vacuum trains were first described by American rocket pioneer Robert Goddard. While the Hyperloop has significant innovations over early proposals for reduced pressure or vacuum-tube transportation apparatus, the work of Goddard "appears to have the greatest overlap with the Hyperloop".
In 1981 Princeton physicist Gerard K. O'Neill wrote about transcontinental trains using magnetic propulsion in his book 2081: A Hopeful View of the Human Future. While a work of fiction, this book was an attempt to predict future technologies in everyday life. In his prediction, he envisioned these trains which used magnetic levitation running in tunnels which had much of the air evacuated to increase speed and reduce friction. He also demonstrated a scale prototype device that accelerated a mass using magnetic propulsion to high speeds. It was called a mass driver and was a central theme in his non-fiction book on space colonization "The High Frontier".
Swissmetro was a proposal to run a maglev train in a low-pressure environment. Concessions were granted to Swissmetro in the early 2000s to connect the Swiss cities of St. Gallen, Zurich, Basel, and Geneva. Studies of commercial feasibility reached differing conclusions and the vactrain was never built.
The ET3 Global Alliance (ET3) was founded by Daryl Oster in 1997 with the goal of establishing a global transportation system using passenger capsules in frictionless maglev full-vacuum tubes. Oster and his team met with Elon Musk on 18 September 2013, to discuss the technology, resulting in Musk promising an investment in a 3-mile (5 km) prototype of ET3's proposed design.[needs update]
From 2003 Franco Cotana led the development of Pipenet which had a small bore evacuated tube for moving freight at up to 2,000 km/h (1,200 mph) using linear synchronous motors and magnetic levitation. A prototype system - 100 m (110 yd) long and 1.25 m (1.37 yd) in diameter - was constructed in Italy in 2005. However development stopped after funding ceased.
China was reported to be building a vacuum based 600 mph (1,000 km/h) maglev train in August 2010 according to a laboratory at Southwest Jiaotong University. It was expected to cost CN¥10–20 million (US$2.95 million at the August 2010 exchange rate) more per kilometer than regular high-speed rail. In 2018 a 45 m (49 yd) loop test track was completed to test some of the technology.
In May 2021 it was reported that low-vacuum test system capable of 1,000 km/h (620 mph) had begun construction in Datong, Shanxi Province. An initial 2 km (1.2 mi) section is to be completed by July 2022 and a 15 km (9.3 mi) test line within two years. The line will be built by the North University of China and the Third Research Institute of China Aerospace Science and Industry Corporation.
