[ExI] Michio Kaku makes 3 predictions about the future

[Darin Sunley]

Mars has gravity, and large amounts of free mass [soil] for radiation
shielding, located at the bottom of a gravity well [boo!] that's
conveniently shallow enough that we can build a space elevator using
materials technology that actually exists [yay!].

That isn't nothing.
