That's amazing tech. Would lasers not be better suited for underground cutting for tunnels?

  Lasers would probably need a lot of energy to cut that much material. Can somebody do a quick analysis how much it would probably cost using conventional/water/lasers?

    Do we even have the capacity to create sustained lasers with sufficient energy output to cut through solid rock?

    Actually they would vaporise the material, not cut it. So yeah, a lot of energy needed !

      In addition you need a lot of fast air exchange to prevent vapor from building up. So the prize of addtional infrastructure is on laser.
