"The same oil and gas drilling techniques that reliably reach kilometer-deep wells can be adapted to host nuclear reactors..."
The last time I looked, oil and gas drilling was done with strings of pipe a few inches in diameter. Unless they're proposing constructing everything in a ship-in-a-bottle fashion, the bore-hole is going to need to be more like a mine-shaft - which is certainly doable, but is not going to be nearly as easy or cheap as they claim.
As well as the reactors, they've also got to get the heat-exchangers, turbines and generators down there too - all of which will require regular maintenance.
Oh, and then it's all got to be connected together.
Finally, they've got to have mile-long cables to bring the power to the surface - which need to be capable of supporting their own weight when strung vertically.
I suspect they're going to burn through a whole load of VC/investor cash before quietly folding and moving on to the next grift/scam/exciting project.
