ClassX Video Lessons Youtube Channel Curiosity Stream The Challenges The Hyperloop System Needs To Overcome | Engineering The Future
In the United States, an ambitious company is working to prove that a hyperloop pod can travel at high speeds along a full-scale track while ensuring passenger safety. In January 2017, the team began assembling the world’s longest full-width hyperloop tube, measuring 1,600 feet. Although this length isn’t sufficient to reach the speeds of an aircraft, it holds promise for supporting high-speed rail.
Embarking on a project that has never been attempted before is thrilling, but it also comes with its own set of challenges. Without established guidelines, the team had to rely on trial and error, learning from mistakes and gradually improving their efficiency. Initially, they managed to install only one or two feet of track per day, but by the end of the project, they were installing 30 to 50 feet daily, thanks to their growing expertise.
Josh Gell, co-founder of Virgin Hyperloop and a former SpaceX employee, was inspired by Elon Musk’s hyperloop paper in 2013. Despite initial skepticism due to some mathematical errors, he became fascinated by the potential to revolutionize transportation. In November 2014, the team started working out of a garage in North Los Angeles, aiming to create a prototype to demonstrate the hyperloop’s feasibility.
After considering various sites for a test track, the team selected a desert area near Las Vegas, close to Los Angeles. The region’s extreme temperature fluctuations posed challenges, causing the steel track to expand and contract significantly. To counter this, they installed rings to accommodate expansion and elevated the tube to minimize environmental impact.
By March 2017, despite weather-related obstacles, the team made significant progress at the test site. They began commissioning the vacuum tent, which creates a low-pressure environment inside the tube. The vacuum system, comprising several pumps, reduces air pressure to the equivalent of 200,000 feet in altitude, drastically cutting air resistance.
A critical component of the hyperloop is its propulsion system, which uses copper coils to generate a propulsion wave that the vehicle follows. These coils interact with magnets on the pod, adjusting the flow of electricity to create varying magnetic fields that propel the pod forward.
Simultaneously, the team worked on the passenger capsule. Structural Engineering Manager Helen Duran highlighted the unique challenges of designing a completely new and untested vehicle. They started from scratch, drawing inspiration from various sources, including NASA’s open-source documentation.
By May 2017, just a year after construction began, enough of the track and sled were ready for testing. Although individual components had been tested separately, this was the first time they would all work together. The initial test confirmed the technology’s viability, achieving speeds of about 70 mph.
Subsequent tests aimed to push the system further and faster. In July 2017, the team reached a top speed of approximately 240 mph, surpassing conventional high-speed rail. This demonstrated that the hyperloop could exceed high-speed rail speeds, even with a relatively short track.
The next focus was on passenger safety. The team constructed a shell for the capsule, altering the vehicle’s characteristics and requiring the team to relearn control mechanisms. Engineers then designed a pressurized capsule capable of withstanding a vacuum equivalent to high altitudes.
By November 2020, the capsule was ready for the world’s first passenger hyperloop ride. Josh Gell was determined to be the first passenger, underscoring the importance of safety. The experience was exhilarating, marking a significant milestone for the company.
Despite this success, the team faced a setback. They needed to build a longer track to achieve true hyperloop speeds, but calculations showed that the technology used in Nevada would not be economically viable for longer distances. They realized they needed to re-engineer their system to make it cost-effective for widespread deployment.
Building and maintaining the hyperloop infrastructure over long distances would be costly, with estimates suggesting expenses could exceed $100 million per mile. As technology advances, upgrading the entire network would also present substantial challenges.

[Music] In America, a company is setting out to demonstrate for the first time that a pod can be propelled along a full-scale track at high speed and that it’s safe for passengers. In January 2017, their team was assembling the world’s longest full-width hyperloop tube at 1,600 feet. While this length is still not enough to reach aircraft speeds, it could potentially support high-speed rail.
The exciting aspect of doing something that has never been done before is that there are no established guidelines. However, this also presents challenges, as there is no one to tell you how to proceed. The team learned through trial and error, making plenty of mistakes but also discovering how to improve efficiency. Initially, they could only install one or two feet of track per day, but by the end, they were installing 30 to 50 feet daily due to their learning curve.
