There's zero technical analysis in this paper. Is there no better source for this discussion? edit: It doesn't even make much sense. It asserts, without any engineering rationale, that a large fusion bomb will efficiently pulverize 4 trillions tons of basaltic rock—the volume of a sphere of basalt 20 km (!!) in diameter—into a fine silt. So many strange assumptions going into that.
