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?

[Faaak]

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