A boring machine showed up at SpaceX headquarters near Los Angeles where it will soon begin to bore some test tunnels, and Musk shared a brief video at TED showing how he hopes to help cities dig their way under and around gridlock.
I'm hoping he will be using it to get high speed transit line pushed through whatever mountain ranges and hills get in the way of making a monorail from LA to NY, Seattle to San Diego
Musk first introduced the world to his tunnel idea in December, when he got caught in one of Los Angeles's notorious traffic jams. Frustrated, he sent out a tweet promising to buy a tunnel boring machine and "just start digging."
Can he pull off making a new high speed rail? Maybe. So far he has accomplished some very difficult and complicated things, like making a car company that competes with Detroit and launching re-usable rockets into orbit and landing them.
the first and easiest problem to see that he;ll need to overcome is the hole in the road left when his elevator takes a car down. Obviously, that's not going to be accepted by any govt in the world. Might as well realize right now that anyone using this system will be paying a fortune to get out of the rat race, and into the new system... and so they'll most likely be driving to a parking garage, and then swiping a credit card. Then they can proceed.
I doubt this has any chance of going anywhere though, getting the US Govt or any other to issue a mining permit and then using it for transportation? Hell, too much govt red tape with the DOT (department of transportation) and potential for disaster or transfer of goods without going through customs/border patrol... see what I mean? Nice idea, at best, but lets get Musk focused back on some needed transportation issues, like high speed rail in the USA.
