Futurology

The technology for drilling deeper is getting better fast. There was a breakthrough by using microwaves to vaporize rock. It's a triple duty method that cases the walls with glass rock, pressure from vapor pushes the condensed dust upwards and removes the material.

It eleminates the need for drilling sludge, excessively long metal rods etc. It's still cheaper to drill conventionally for 3km but to reach the 10km for EGS it's a lot cheaper. Drilling conventionally becomes exponentially more expensive with depth
