The Original Hyperloop Concept: A Leap Toward Subsonic Tube Travel

While Elon Musk popularized the term “Hyperloop,” it’s essential to note that the initial conceptual groundwork for tube transportation was laid by Daryl Oster. His visionary idea of transporting passengers and goods in tubes at remarkable speeds sparked the imaginations of engineers and entrepreneurs worldwide.

Elon Musk’s Hyperloop concept, as detailed in his 2013 alpha-design white paper, was a bold step forward in this field. It envisioned a high-speed transit system where passengers or cargo would be transported in capsules or “pods.” These pods would travel through low-pressure tubes, propelled with linear electric motors while levitated via onboard fans. The design aimed to achieve silent, turbulence-free travel at speeds of up to 760 mph, making it a subsonic mode of transportation. The original Alpha design required a low pressure environment, not a vacuum.

Musk’s capsules were envisaged to be large, aiming to accommodate about 28 passengers at a time, much like a traditional train or subway car. However, the large capsule design has sparked a debate. Would it be more efficient and cost-effective to build smaller, packet-like capsules? Hyperloop One and other efforts have come to that conclusion.

When we consider the Hyperloop’s ambitious speed and efficiency targets, smaller capsules emerge as an intriguing proposition. The smaller the capsules, the lower the infrastructure costs, as less material would be required for tube construction. Furthermore, smaller capsules could potentially reduce the energy needed for propulsion and increase the system’s overall efficiency.

As we turn to the adaptations and iterations of Musk’s original Hyperloop concept, we see a fascinating diversity in capsule design and strategy. Let’s take a closer look at how companies like Hyperloop One, ET3, and HyperloopTT have interpreted and expanded upon the original vision for tube transportation.

Hyperloop One: From Passenger Travel to Freight

Among the various companies striving to make tube travel a reality, Hyperloop One, known from 2017 to 2022 as Virgin Hyperloop, has emerged as a significant player. Founded in 2014, this American transportation technology company has committed itself to the commercialization of the Hyperloop concept, though not without making some notable changes to the original vision.

Hyperloop One’s technical adaptations have led to a variation of the vacuum train concept. They have managed to design systems intended to move cargo at speeds comparable to airlines, but at a fraction of the cost. These systems operate with capsules suspended by magnetic systems in vacuum tubes, embodying Musk’s original concept of air-bearing levitated pods but with some strategic shifts.

A pivotal change was Hyperloop One’s decision to transition its focus from passenger travel to freight. This strategic shift was accompanied by a reconsideration of the size and design of their capsules. While passenger capsules would need to be large enough to accommodate humans comfortably, cargo capsules could be smaller and more akin to packets. This shift towards smaller, packet-like capsules has the potential to enhance the efficiency and cost-effectiveness of the system significantly.

However, the journey towards commercial operations, which Hyperloop One aims to launch by 2030, has not been without its challenges. After more than 400 uncrewed tests and the first human trial conducted at a speed of 107 mph, the company decided to abandon plans for human-rated travel in February 2022. The decision led to a significant reduction in workforce and a reversion to the company’s original name, Hyperloop One, after parting ways with the Virgin branding. Despite these hurdles, Hyperloop One’s journey underscores the evolving nature of Hyperloop technology and the importance of flexibility and innovation in realizing this ambitious concept.

HyperloopTT – Transportation Technologies: Size Matters

Another noteworthy player in the Hyperloop saga is Hyperloop Transportation Technologies (HyperloopTT). This company has embraced the original Hyperloop vision, but it’s their approach to capsule design that merits our attention, particularly in the context of our discussion on capsule size.

HyperloopTT has proposed large passenger capsules that seem to align with the original vision of Musk. Their designs showcase spacious capsules that prioritize passenger comfort and seek to provide an immersive travel experience. However, these larger capsules, while attractive in their passenger-centric design, come with a set of challenges that warrant further exploration.

The larger the capsule, the larger the tube needs to be to accommodate it. This requirement could lead to significant increases in infrastructure costs due to the increased materials needed for tube construction. Additionally, larger capsules could potentially consume more energy for propulsion, impacting the system’s overall efficiency.

This raises the question: While large capsules may offer an enhanced passenger experience, are they the most efficient and cost-effective solution for the Hyperloop system? As we look to the future of Hyperloop technology, the importance of balancing passenger comfort with system efficiency and affordability becomes increasingly apparent. This delicate balance forms the crux of the debate on capsule size, and it’s here that we see the case for smaller, packet-like capsules gain strength.

ET3: Hypersonic Speeds and the Case for Smaller Capsules

When discussing the evolution of tube transportation and the debate around capsule size, it is crucial to mention Evacuated Tube Transport Technologies (ET3). Founded by Daryl Oster, who we’ve acknowledged as the original brainchild behind the concept of tube transportation, ET3 has been a significant force in advocating for smaller, packet-like capsules.

ET3’s vision diverges significantly from the large capsule design proposed by companies like HyperloopTT. The company’s design involves small capsules, capable of carrying up to six people or an equivalent amount of cargo. These smaller capsules are designed to travel in tubes with a significantly smaller diameter than those proposed for larger capsules. This design choice aligns with the principle we’ve been exploring – smaller capsules could lead to more cost-effective infrastructure due to the reduced size of the tubes.

But the innovation of ET3 doesn’t stop with capsule size. The company has also pushed the boundaries of speed. While Hyperloop concepts are subsonic, aiming for speeds around 760 mph, ET3 envisions a hypersonic model with an estimated top speed of 4000 mph. This leap in speed is another domain where the smaller capsule design of ET3 could have an advantage – smaller capsules could potentially manage high speeds more effectively.

By embodying the principles of smaller, packet-like capsules and hypersonic speeds, ET3 illuminates a path that others in the field, such as Hyperloop One, have begun to follow. It demonstrates that the original concept, as conceived by Oster, remains a guiding force in the evolution of tube transportation technology. Hyperloop One’s latest vision also includes ET3 capsule and tube switched network for seamless travel from beginning to end. Switching and smaller – hypersonic speed capsules are the real game changer when considering intercontinental travel. How quickly can you get from San Francisco to Tokyo at 4000 Mph? Think about it…

In conclusion, while the journey towards operational tube transportation systems is still ongoing, the discourse around capsule size is an essential facet of these technological advances. The strategic choices made by companies like Hyperloop One, HyperloopTT, and ET3 will significantly influence the future of tube transportation. Whether the industry will lean towards larger, passenger-centric capsules or smaller, packet-like capsules remains to be seen.
