Re: WOW
Removing cuttings via a non-liquid medium is going to be a real bugger of a problem.
Drilling mud would not work well, I think.
And how to hold down liquids and gasses under great pressure without heavy barium-based muds?
This is very interesting, but I see it being used in hard rock mining first.
And I would not want to be too near if the hot laser cut into a methane pocket, although the lack of O2 to burn would be a very good limit on explosive problems down hole.
But it still totally cool.
