LIMITLESS Project Pioneers Sustainable Hyperloop Technology for High-Speed Travel

Introduction-A Leap Towards Tomorrow's Travel

The LIMITLESS project—a collaborative effort between EPFL, the School of Business and Engineering Vaud (HEIG-VD), and Swisspod Technologies—has set a new benchmark in the development of hyperloop technology. This project aims to bring sustainable, efficient, and ultra-fast transportation systems closer to reality, presenting a modern, scalable alternative for intra-continental travel. This recent achievement, unveiled during EPFL's Hyperloop Day, underscores the potential of a high-speed transit system operating on low-pressure infrastructure, marking a breakthrough in sustainable transit innovation.

The Foundation of LIMITLESS-Hyperloop’s Technological Backbone

The hyperloop concept envisions high-speed travel within a vacuum or low-pressure tube that minimizes air resistance, allowing capsules to reach remarkable speeds with enhanced energy efficiency. The LIMITLESS project, supported by Innosuisse, builds on this concept by developing a linear induction motor (LIM) that integrates both levitation and propulsion functionalities, a transformative advancement over conventional approaches. This LIM-based system enables the hyperloop to operate on a passive infrastructure, dramatically reducing implementation costs while increasing efficiency.

Swisspod Technologies, under the guidance of CEO Denis Tudor, collaborated closely with EPFL and HEIG-VD to leverage EPFL’s hyperloop testing facility, located in Lausanne. This facility, a circular track with a diameter of 40 cm and a circumference of 125.6 meters, serves as a scaled-down version of the hyperloop system envisioned in Tudor’s doctoral research at EPFL. The structure allows direct scalability of test results to full-scale performance, giving the project an ideal testing ground to refine core technologies and propulsion mechanics.

A Controlled Environment-The Testing Facility’s Impact on Innovation

The EPFL testing facility plays a pivotal role in LIMITLESS’s ability to rapidly prototype and iterate on hyperloop technology. Designed with a 1:12 scale factor, the circular loop track replicates real-world hyperloop conditions in a smaller format. The environment is controlled at 50 millibars of pressure, simulating the low-pressure conditions necessary for hyperloop travel. This enables accurate testing of speed, thrust, and energy efficiency without the complications of a full-scale build, reducing both costs and time for each test cycle.

During the project’s experimental phase, the team conducted a series of 82 tests, meticulously analyzing the propulsion, power electronics, communication systems, and thermal management of the capsule. The infrastructure’s closed-loop design ensures that there is no inherent length limitation, offering the team an unrestricted environment for exploring the hyperloop’s full range of capabilities. This approach allows researchers to systematically assess every aspect of the technology, including energy efficiency and acceleration, before transitioning to larger-scale implementations.

Record-Breaking Achievements-Speed and Distance Milestones

A significant milestone for LIMITLESS was the successful completion of a hyperloop journey equivalent to 141.6 km at full scale. In the reduced-scale setup, this covered a distance of 11.8 km, with the capsule reaching a top speed of 40.7 km/h—translating to 488.2 km/h in full-scale terms. These figures demonstrate the hyperloop’s potential to become a formidable mode of high-speed transport, rivaling traditional rail and air travel in both speed and efficiency.

The capsule, fully autonomous in terms of navigation, energy, and propulsion, contains its own energy source, allowing it to operate independently of any external power supply. This self-sufficient approach emphasizes the hyperloop’s reliance on minimal infrastructure, making it a highly adaptable solution for regions pursuing efficient and sustainable transit alternatives. The project's success reinforces the scalability of hyperloop technology, paving the way for its use in longer-distance routes and real-world applications.

Linear Induction Motor (LIM)- The Heart of Hyperloop Propulsion

One of the core advancements in LIMITLESS is the development of a linear induction motor (LIM) that powers both levitation and propulsion. This novel LIM design, spearheaded by Simone Rametti’s doctoral research at EPFL’s Distributed Electrical Systems Laboratory (DESL), represents a leap in hyperloop engineering. Unlike traditional propulsion systems that separate levitation and movement, the LIM used in LIMITLESS integrates both functionalities into a single motor, ensuring optimal energy conversion efficiency and streamlined design.

Mario Paolone, professor at DESL, highlighted the importance of this innovation, explaining, “By leveraging this knowledge, we were able to integrate levitation and propulsion functionalities into a single motor with very high energy conversion efficiency.” This efficient use of energy is a critical factor in achieving sustainable hyperloop travel, reducing the environmental impact associated with long-distance transportation.

Testing in a Controlled Environment-82 Trials for Precision and Efficiency

The series of 82 trials conducted at the EPFL facility were instrumental in pushing the boundaries of what the LIMITLESS hyperloop system could achieve. The team evaluated each component under varied conditions, assessing factors such as energy consumption, thrust variations, and LIM response across different speeds and pressure levels. By operating the tests within a closed-loop, low-pressure environment, the researchers could simulate realistic hyperloop conditions without external variables affecting the results.

The team’s extensive data collection has provided invaluable insights into the performance and scalability of the LIM-based propulsion system. Testing scenarios ranged from acceleration and cruising to coasting and braking, allowing the researchers to refine their control algorithms and ensure consistent performance across various travel phases. These findings not only affirm the technical viability of hyperloop travel but also lay a foundation for further optimization as the project advances.

LIMITLESS’s Vision-Sustainable High-Speed Travel

With the LIMITLESS project, EPFL, Swisspod, and HEIG-VD are leading the charge toward sustainable, efficient hyperloop travel. The focus on a passive infrastructure eliminates the need for complex external power sources, allowing hyperloop systems to be implemented in a cost-effective manner that is both adaptable and environmentally friendly. The modular design of the LIM and the closed-loop test infrastructure also support future scalability, making it easier to adapt the system for different regional needs and travel distances.

Cyril Dénéréaz, Swisspod’s CTO, emphasized the strategic advantages of LIMITLESS, stating, “Our infrastructure operates as a closed loop, so it truly is LIMITLESS, free from any inherent length limitations. The way our track was designed enables us to consider everything — the capsule’s energy efficiency, the propulsion systems, and more — in ways that other hyperloop infrastructures cannot.” This adaptability allows for comprehensive experimentation and optimization, giving LIMITLESS a unique edge in the hyperloop landscape.

Beyond the Test Track-Future Applications and Real-World Potential

LIMITLESS’s contributions extend beyond the immediate scope of hyperloop technology, with potential applications in automotive, metro, rail, and aerospace industries. The project’s innovations in propulsion and levitation could influence a range of high-speed transportation modes, promoting sustainability and efficiency across multiple sectors. As the LIMITLESS team continues to refine their technology, they are setting the stage for hyperloop to emerge as a viable alternative for passenger and freight transport on a larger scale.

Swisspod’s CEO, Denis Tudor, envisions a future where hyperloop not only transforms long-distance travel but also reshapes entire economies by enhancing connectivity between urban and rural areas. “This milestone brings us closer to a future where hyperloop becomes a catalyst for societal change. Putting our years of technological innovation to the test is a critical step in pushing the development and deployment of efficient hyperloop technologies worldwide,” he remarked. Swisspod plans to test a hyperloop freight transport system at a larger facility in the United States, further expanding the practical applications of LIMITLESS’s technology.
