Musk Plans Subway For Cars

|Includes: ACM, Tesla, Inc. (TSLA)

The Dos Equis beer ads are dead wrong; Elon Musk and not some guy with a beard is the most interesting man in the world. Just last week, Musk unveiled yet another revolutionary transportation system proposal.

Musk revealed plans to build subways for cars to ease traffic congestion at a TED talk in Vancouver, The Verge reported. He even played a video that showed how cars can be moved through the tunnels.

"The deepest mines are much deeper than the tallest buildings are tall, so you can alleviate any arbitrary level of open congestion with a 3D tunnel network," Musk said.

Musk's Subway for Cars

The idea is to put cars on devices called "electric skates" that can be moved onto elevators. The elevators would take the cars into tunnels where they moved on a sort of subway for autos.

This idea sounds rather dumb, because a passenger subway would be cheaper and far more practical. It would be a lot cheaper for people to park their vehicles and take an elevator, escalator or stairs down to the subway.

Musk is apparently serious about this scheme; he's bought a tunneling machine that's been moved to SpaceX Headquarters in Hawthorne, California, The Verge reported. If that was not enough Musk has formed a tunneling venture he calls the Boring Company.

Ironically, Musk's latest play toy was formerly used by the Los Angeles Metropolitan Transportation Authority (MTA) to dig subway tunnels. Musk's concept is that dozens of tunnels for moving cars can be dug under city streets. The idea might be attractive to urban planners because it would make for far more pedestrian-friendly cities by banishing traffic underground.

Hyperloop Subway Proposed

Musk proposed a far more practical solution for crowded cities - a Hyperloop subway system. In response to a question from TED Curator Chris Anderson Elon noted that Hyperloop tech can be used in tunnels.

Hyperloop works well underground because most tunnels are already designed to contain much more vacuum than the system needs, Musk pointed out.

It would possible to build extremely long Hyperloop subways, Musk noted. He proposed a route from Washington D.C. to New York City.

Musk is not the only one interested in underground Hyperloops, Hyperloop One has put up blog posts about the idea. Hyperloop One is working with a company that has a lot of experience in tunneling, AECOM (NYSE: ACM). The engineering, design and construction company is involved in one of the world's most ambitious railroad tunnel projects the Crossrail tunnel under London.
