ELON MUSK'S BORING COMPANY REVEALS PRUFROCK TBM'S MOST DISRUPTIVE FEATURE

Summary from the TLDR newsletter

The Boring Company's Prufrock-5 tunnel boring machine (TBM) will begin tunneling by December 1. One of the key features of the Prufrock machines is that they can be retrieved, upgraded, and deployed again with improvements. Standard TBMs are often left underground at the end of projects because retrieving them is usually too expensive and impractical. TBMs from the Boring Company could eventually be as reusable as SpaceX's boosters.
