THE $20-TRILLION TUNNEL THAT COULD LINK NEW YORK AND LONDON

Summary from the TLDR newsletter

A transatlantic tunnel connecting the UK to the US may be possible, but it would be extremely expensive, with estimates of almost $20 trillion for the project. It would take many years for the 3,000-mile tunnel to be completed - it took six years to build the 23.5-mile Channel Tunnel linking England and France. Developments in vacuum tube technology have made the concept more viable. A vehicle traveling in a hyperloop system could theoretically reach speeds of more than 3,000 mph, making the journey between London and New York barely an hour long.
