Few people in the world don't know who Elon Musk is, and that's exactly the way the billionaire entrepreneur wants it. Musk's cult of personality is largely responsible for powering his clean energy cars and fueling his SpaceX rockets.
His handlers court Hollywood. He's appeared in Iron Man, dated actresses, and has his own rocket company. Musk has cornered cool, and his clean energy empire has been built on that image.
