Did he explain how any of this was actually going to happen? How he would make resources so plentiful? Or is this just like the Hyperloop, where he claims to have invented something first devised a century beforehand, tells everyone it's the best way forward and it's not that hard, but does none of the actually engineering, design or even starts a project to make it? I mean, we all know he only did it so the California High Speed Rail would get shelved and he'd sell more cars, and so far no hyperloop has come into existence (and never will) so I fail to see why anyone would pay any attention to him at this point.
