Quite an amazing concept: digging huge caverns on the moon, put some water in them, blow up fusion bombs, and get the generated steam energy with turbines.

I like the way the guy is capable of "thinking big". No wonder he was inspired by the Orion project.
Yet the energy would have to be sent via microwaves to geostationnary satellites, therefore I wonder if this whole thing would be much more usefull than the Sun itself anyway. After all, our star is already a fusion reactor in space that transmits its energy via radiation.
