Could an Undersea Hyperloop Train Tunnel Offer One-Hour Trips From London to New York?

"Proposals for a tunnel connecting the U.K. to the U.S. underneath the Atlantic Ocean have resurfaced," reports Newsweek, "but with a price tag of almost $20 trillion, the project is a big ask." With the two global cities being over 3,000 miles apart, construction would take several years —...

By creating a vacuum within the tunnel and using pressurized vehicles, trains traveling along the structure could theoretically reach speeds of more than 3,000 mph, making the journey between London and New York barely an hour long. Cutting the intercontinental journey down to a matter of minutes means that for the first time, the Transatlantic Tunnel justifies the hefty price tag that undersea construction comes with, as it would become significantly more efficient and environmentally friendly than flying. Weighing in, Elon Musk "has suggested the idea of building a '£20 trillion' underground tunnel link from London to New York appears to be a genuine possibility," according to the site LADbible, "although he says he could do it for less."
