California utilities have spent years undergrounding power lines to mitigate fire risks.
U.S. Department of Energy launched GOPHURRS program to develop more efficient undergrounding technologies.
Case Western Reserve University in Ohio is building a self-propelled robotic sleeve that mimics earthworms’ characteristic peristaltic movement to advance through soil.
Case’s drilling concept generates the force needed for the tip from the peristaltic segments within the borehole.
As the path gets longer, only the front segments dig deeper.
Another key difference from HDD is integrated conduit installation.
The project aims to halve undergrounding costs, though it's too early to commit to a specific cost model.
