Elon Musk, the visionary entrepreneur known for pushing the boundaries of technology, has floated another ambitious idea: an underwater tunnel that would connect London to New York in just 54 minutes. The concept, which Musk claims his Boring Company could build for £20 billion, has sparked intrigue and debate around the feasibility of such a project. Let’s dive into this revolutionary proposal, its implications, and whether it could truly reshape global travel.

Musk’s Vision: From Rockets to Underwater Tunnels
Elon Musk is no stranger to bold ideas. From Tesla’s electric vehicles to SpaceX’s reusable rockets, his ventures consistently aim to redefine what’s possible. Recently, Musk proposed using SpaceX’s Starship rocket to transport passengers between cities at speeds of up to 27,000 km/h. With a promise to connect cities in under an hour, he teased the potential for journeys like London to New York in just 29 minutes.
While rocket-based travel grabs headlines, Musk’s latest idea takes a different route—literally. Responding to speculation about a $20 trillion underwater tunnel, Musk suggested that his infrastructure company, The Boring Company, could build it for a fraction of the cost.
“The @boringcompany could do it for 1000X less money,” Musk tweeted, hinting at his confidence in delivering cutting-edge tunneling projects at a significantly reduced price.
The Boring Company’s Expertise in Tunneling
Founded in 2017, The Boring Company focuses on innovative tunneling solutions to combat traffic congestion and revolutionize infrastructure. Known for projects like the Las Vegas Convention Center Loop, which uses electric vehicles to transport passengers underground, the company aims to make tunneling faster, cheaper, and more efficient.
Musk’s suggestion of an underwater tunnel connecting London and New York isn’t entirely far-fetched when considering The Boring Company’s mission. The idea would involve a high-speed train or vacuum tube, potentially leveraging magnetic levitation (maglev) technology to achieve speeds far beyond conventional rail systems.
The Concept of Underwater Tunnels: Feasibility and Precedents
Building an underwater tunnel on such a massive scale may sound futuristic, but the idea isn’t unprecedented. Engineering feats like the Channel Tunnel, which connects the UK to France, demonstrate that underwater transportation is possible.

Current Underwater Tunneling Projects
One relevant example is the Fehmarnbelt Tunnel, currently under construction to connect Denmark and Germany beneath the Baltic Sea. Spanning 18 kilometers, the tunnel will accommodate both road and rail traffic and is expected to open in 2029.
Denise Juchem, a spokesperson for Femern A/S, the company behind the project, explained that the tunnel’s design prioritizes environmental sustainability, cost-effectiveness, and weather resilience. Markus Just, the Tunnel Design Quality Manager, noted the intricate planning required, including specialized basins that allow prefabricated tunnel segments to float and be transported to the site.
The Fehmarnbelt Tunnel’s successful implementation could serve as a stepping stone for even larger projects, like Musk’s proposed London-to-New York connection.
The Science Behind Musk’s Underwater Tunnel Proposal
Musk’s concept likely involves a combination of advanced tunneling techniques and high-speed transportation technology. Here’s how it could work:
- Vacuum Tubes and Maglev Technology: To achieve the 54-minute travel time, the tunnel might utilize vacuum tubes and maglev trains. Vacuum tubes significantly reduce air resistance, while magnetic levitation eliminates friction, allowing for ultra-fast travel.
- Deep-Sea Tunneling: The tunnel would need to run beneath the Atlantic Ocean, requiring advanced engineering to withstand immense water pressure and geological challenges.
- Environmental Considerations: Minimizing environmental impact would be crucial. Drawing lessons from the Fehmarnbelt Tunnel, careful planning and eco-friendly construction methods would be essential to gain approval for such a project.
Challenges and Obstacles to Overcome
While Musk’s vision is undoubtedly exciting, there are significant challenges to address before this project can become a reality.
1. Financial Feasibility
Musk claims The Boring Company could complete the project for £20 billion, a fraction of the $20 trillion estimate floated by others. However, even with reduced costs, securing funding for such a colossal project would be a daunting task. Governments, private investors, and international partnerships would need to collaborate on financing.
2. Engineering Complexities
The proposed tunnel would span thousands of kilometers beneath the Atlantic Ocean, requiring groundbreaking engineering solutions to tackle water pressure, geological stability, and the sheer scale of the construction.
3. Regulatory Approval
A project of this magnitude would involve multiple countries, requiring extensive negotiations, environmental assessments, and compliance with international laws. Securing regulatory approval could take years, if not decades.
4. Safety and Reliability
Ensuring the safety of passengers traveling at unprecedented speeds through an underwater tunnel is non-negotiable. Advances in materials, structural integrity, and emergency response systems would be critical.
Why Musk’s Proposal Matters
Even if the London-to-New York tunnel remains a concept for now, Musk’s vision has reignited conversations about the future of global transportation. Here’s why it’s significant:
- Redefining Connectivity: A 54-minute journey between London and New York would revolutionize international travel, making the world more interconnected than ever before.
- Driving Innovation: Musk’s proposal pushes the boundaries of what’s possible, inspiring engineers, policymakers, and visionaries to think big.
- Environmental Benefits: High-speed rail and maglev technologies offer a greener alternative to air travel, reducing carbon emissions and dependence on fossil fuels.
The Future of High-Speed Global Travel
While the feasibility of an underwater tunnel linking London and New York remains uncertain, Musk’s track record of turning ambitious ideas into reality gives the concept credibility. Whether through vacuum tube trains, rockets, or other futuristic technologies, the dream of connecting the world in under an hour is closer than ever.
For now, projects like the Fehmarnbelt Tunnel provide a glimpse into what’s achievable with current technology. As engineering advances and infrastructure funding align, Musk’s vision might one day become a reality—forever transforming the way we travel and connect across the globe.
Conclusion: The Journey Ahead
Elon Musk’s proposal for a £20 billion underwater tunnel from London to New York is an audacious idea that captures the imagination. While there are immense technical and logistical hurdles to overcome, the concept serves as a powerful reminder of humanity’s capacity to dream big.
As discussions about high-speed global transportation continue, Musk’s vision could inspire the next generation of engineers, entrepreneurs, and policymakers to push the boundaries of innovation. One thing is certain: the future of travel is bound to be faster, greener, and more connected than we ever imagined.
