He sure does talk. I mean he talked about Electric cars being a reality NOW...then produced the Tesla roadster as proof, the Model S as the first fully designed Tesla offering, and soon the Model 3 (which will introduce an affordable electric vehicle for all).

He talked about the inefficiencies of the space program and the fact that the rockets were one time use and discard...then worked to produce a reusable rocket that can land (even on mobile platforms at Sea). He proved this could work, and then showed NASA...yes NASA that you could reuse the rockets when they said it could NOT be done.

Elon is a visionary. He is years ahead in his thinking. So while he does talk quite a bit, you will start to see what he is speaking about come to fruition.

Take a look at the Tesla Hawaii project. Very very cool.

Finally, keep in mind that many of the entrenched entities that today mfg automobiles, rockets, sell you oil, generate your power etc DO NOT want Elon or his companies to succeed. The fact that he has gotten as far as he has, as fast as he has is absolutely amazing.

OMG! The Roadster was a hoax? And those Model X and Ss I see daily in my city aren't real? Don't believe my lying eyes? And there really isn't a Model E(SEX lives on)?The astronauts are going to starve because NASA thinks he has a rocket. And that video of the electric cart in the tunnel he released recently was really found footage from the same area they found the Blaire Witch stuff. What the hell is going on? Please tell Power Wall is real. It all seemed so real. Who stole my ruby slippers?
