Drilling cost is usually estimated as ~depth^2.

So, a 1km geothermal well? Break even, and you are limited to only a few places in the world.

A 5km geothermal well (needed for broad power availability)? 25x the cost...

So, sure, if you can get a 25x cost reduction in an already cutthroat industry, all power to you (no pun intended).
