Hyperloop: A Vision of Future Transport

Hyperloop, an innovative ultra-high-speed transportation system that operates at ground level and is powered by solar energy, was first proposed in 2013 by Elon Musk. The concept, detailed in a 58-page white paper, describes a network of steel tubes in which pods travel at speeds of up to 1,220 km/h (760 mph) in a near-vacuum environment using magnetic levitation and propulsion. The system would link cities across the globe, with Musk releasing his “Hyperloop Alpha” white paper for open-source research and development by universities and companies. Despite the passage of more than a decade, only two people have experienced a ride on a hyperloop pod.

The design behind Hyperloop is similar to a maglev train system. It uses magnets to levitate the pods, enabling them to float above the track, and another set of magnets to push them forward. The track itself is contained within a low-pressure tube, where almost all air is removed, creating an environment that reduces friction and allows for incredibly high speeds.

Advocates argue that Hyperloop could revolutionize transport by significantly lowering greenhouse gas emissions compared to traditional methods. It could also reduce energy consumption, air pollution, noise, traffic congestion, and even decrease accidents. Several companies, including Musk’s Boring Company and Hyperloop Transportation Technologies, are actively developing the technology. However, one of the companies, Hyperloop One, ceased operations in late 2023, as reported by Bloomberg. Projects are also underway in Canada and the Netherlands. In 2016, Musk’s Boring Company set up a prototype tube in front of SpaceX’s headquarters in Hawthorne, California, but after years of inactivity, it was dismantled in 2022 at the city’s request.

The first full-scale Hyperloop test track, constructed by Virgin Hyperloop (formerly Hyperloop One) in 2016, was 500 meters (1,640 feet) long, built in Las Vegas. In 2020, it made history by being the first to transport passengers, with two employees riding at speeds of 172 km/h (107 mph). Smaller test tracks have since been set up in France and Germany.

Despite the potential of Hyperloop, the technology still faces significant hurdles. The costs are steep: for example, building just one kilometer of Hyperloop track was estimated to cost over $75 million. Other challenges include the complexity of meeting government safety standards, integrating the system with existing infrastructure, and minimizing environmental impact during construction. There are also concerns about security, such as the risk of attacks on the system, as well as the physical forces passengers would experience, which might cause discomfort or nausea.

High-Speed Rail (HSR): The Current Alternative

High-speed rail (HSR) refers to passenger trains that typically operate at speeds of at least 200 km/h (124 mph), with some trains reaching up to 355 km/h (221 mph). More than 20 countries, primarily in Asia and Europe, have established HSR networks. In certain regions, HSR is a competitive alternative to air travel for distances up to about 1,000 km (620 miles).

The first high-speed rail service was Japan’s Shinkansen line, launched in 1964 ahead of the Tokyo Olympics. Connecting Tokyo and Osaka, the line became famous for its speed and the distinct aerodynamic design of the trains, earning the nickname “bullet train.” Many groundbreaking features were incorporated into the Shinkansen, including prestressed concrete ties and welded track sections.

The success of Japan’s Shinkansen inspired other countries to adopt similar technology. Europe’s first high-speed rail line debuted in Italy in 1977 between Rome and Florence, followed by France in 1981 with the Paris-Lyon route. In 2007, the Channel Tunnel Rail Link (CTRL) in the UK, now called High-Speed 1, connected London to mainland Europe. Other notable HSR systems include Korea’s high-speed rail, which opened in stages between 2004 and 2010, and Morocco’s Al Boraq line, which brought the first high-speed railway to Africa in 2018. However, there are no high-speed rail systems in Latin America.

China, which had no high-speed rail at the start of the 21st century, now leads the world with a vast network covering 38,000 km (24,000 miles). The country plans to extend its network to nearly 70,000 km (43,000 miles) by 2035, positioning high-speed rail as a symbol of China’s economic growth and technological prowess.

In contrast, the United States has struggled to develop a widespread high-speed rail network. Despite early efforts, including the 1965 High-Speed Ground Transportation Act, America’s high-speed rail system has been limited. The Acela Express, which operates in the Northeast Corridor between Boston and Washington, D.C., is the only operational high-speed rail line in the U.S., but its speed is constrained by aging infrastructure and other limitations. Although the 2008 California ballot initiative to fund a bullet train between San Francisco and Los Angeles saw support, the project has faced delays and cost overruns, with only one section under construction by 2022.

There is hope for high-speed rail in the U.S. due to the 2021 Infrastructure Investment and Jobs Act, a $1 trillion law that allocated $66 billion for rail modernization. The funding is meant to improve Amtrak services, including replacing outdated infrastructure and boosting train speeds. Amtrak’s new trains, built by French manufacturer Alstom, are set to be the fastest in the U.S., capable of reaching nearly 300 km/h (186 mph), although their speed will be limited at first due to existing infrastructure constraints.

A noteworthy addition to the global railway system was the Gotthard Base Tunnel, which opened in 2016 in Switzerland. At 57 km (35 miles), it’s the world’s longest and deepest railway tunnel. It facilitates faster travel for both freight and passengers between northern and southern Europe, while also offering significant safety and environmental benefits.
