Could there be a completely novel way of digging ? Maybe with Laser ? maybe a chemical process ? or a high pressure water cutter ? what if you could cut small

Could there be a completely novel way of digging ? Maybe with Laser ? maybe a chemical process ? or a high pressure water cutter ? what if you could cut small block of stone in the hole without using so much energy reducing it to sand ?
- mNovak 5y agoI imagine part of the challenge would be undercutting the resulting cylindrical rock (still attached to bedrock at the bottom). Also there's the significant issue of removing the cut rock from 10k feet below ground. This is much easier to do with sand which gets picked up in a mud slurry.
