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

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

                    ' 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.
