Another consideration is the technology in the tunnel boring machine or subterrene. Experiments in the 80's using a fission reactor melting lithium to heat rods used to melt and fractures the stone and soil in front showed some promise. The Project has fusion reactors and laser technology. It is possible that a Project built borer could be arguably simpler than modern borers.
