Elon Musk Really Is Boring  

Posted by Big Gav in

Bloomberg has an update on Elon Musk's tunnelling hobby - Elon Musk Is Really Boring.

Tunnel technology is older than rockets, and boring speeds are pretty much what they were 50 years ago. As with space launches, tunnels are often funded through cost-plus government contracts, in which the contractor assumes no risk for cost overruns, which tend to be enormous as a result. Famously, Boston’s Big Dig, which moved a section of Interstate 93 underground, was delayed by roughly eight years and cost $12 billion more than originally planned, but all tunnels tend to be wildly expensive. In L.A., plans to extend the subway’s Purple Line by 2.6 miles will cost more than $2.4 billion and take almost 10 years. “It’s basically a billion dollars a mile,” Musk says. “That’s crazy.”

Musk wouldn’t comment on Trump, but a person close to him says that while the Boring Company would be open to building tunnels as part of Trump’s infrastructure plan, it intends to move forward regardless of what happens in Washington. Musk says he hopes to build a much faster tunneling machine and use it to dig thousands of miles, eventually creating a vast underground network that includes as many as 30 levels of tunnels for cars and high-speed trains such as the Hyperloop.

Objections spring to mind. Such as: Wouldn’t having hundreds of feet of hollow tunnels destabilize the ground? Nope, Musk says, the mining industry does it all the time. “The earth is big, and we are small,” he says. “We are so f---ing small you cannot believe it.” Not only are these megatunnels possible, he argues, they’re the only way we can rid ourselves of the scourge of traffic.

“We have skyscrapers with all these levels, and we have a flat, two-dimensional road system,” he says. “When everyone decides to go into these structures and then exits them at the same time, you’re going to get jammed.” Tunnels, on the other hand, would represent a 3D transportation network.
