Being faster than a snail is truly an innovation in tunneling. TUM Boring – Innovation in Tunneling is an initiative of the Technical University of Munich consisting of 60 highly motivated students who have teamed up to innovate tunneling towards a greener future by developing the fastest and fully functional Tunnel Boring Machine (TBM). Along with their vision TUM Boring also participates in the first Not-a-Boring Competition by Elon Musk’s The Boring Company. The goal is to design and build a Tunnel Boring Machine that tunnels faster than a snail crawls and accelerate the transition to three-dimensional transportation.
