This is only in concept at the moment. Robots that use plasma to vaporize the rock in a tunnel to drill 100 times faster than today’s boring machines. And 98% cheaper.
This makes way for a great deal of progress in underground dwellings, underground transportation, underground cables and much more. I’m actually very excited because when the Earth heats up from global warming we got no place else to go, right???
If you are a science fiction fan you would have seen this kind of technology before. I recall that one work of science fiction art actually used this concept to travel toward the earth’s core.
The big problem is that is if the rig fails and everything around you cools off, you can find yourself stuck in solid rock!
