Just watched this on YT (unrelated to this post) and it's a fantastic upload. They're already achieving 1m/hr drilling speed which stomps traditional bit-drill tech by a lot. And they can go way deeper.

This is why investing in stuff like nuclear fusion isn't useless. People shitting on it are just ignorant of how science works and how things that seem completely unrelated to each other can be transferable or even be foundational. Very nice to see gyrotrons used in the manner.

My thought however is: how stable will these holes be? There's probably a few things moving at that depth that could easily sheer off a part of the hole.
