        This prufrock thing pure vaporware. Elon Musk has no expe...rience in mechanical engineering yet alone in tunnel boring machines. You may hire some experien...this and that on a Lovat TBM. But inventing a tunnel boring machine 10 times faster than standard...

          ' thanks to the Japanese engineers' contributions to tunnel boring machine technology'? Are you serious? The last time I checked it was the USA a.k.a Robbins, who invented TBM and took it further than anyone else.

                  Elon Musk was not a rocket scientist either. I am sure those rockets are more complicated than tunnel boring machines.

                    Hi Peter, actually, it can... It is an old NFM machine from the Thomson Line project in Singapore that was refurbished by Robbins for this drive in Mumbai.
