When talking about Elon Musk, one has to admit the guy is a millipede with an untamable amount of energy.
(Tip; the twitter handle BoredElonMusk is a gem !)
His latest focal point are TBM’s, aka Tunnel Boring Machines.
The company is called: “The Boring Company” and as with almost every company he starts, there’s a competition!
This time it’s a race (km/h) between a snail (Gary) and a TBM (Godot).

Musk also gave a TED talk about the subject of tunneling (ofcourse from an USA perspective).
