Tesla's Elon Musk: "I ran out of cash"

Tesla Motors CEO Elon Musk seems to have it all. The electric-car entrepreneur is the toast of Silicon Valley, Sacramento, and Tokyo after unveiling a plan to revive Toyota’s shuttered NUMMI plant last week. And deal-hungry Wall Street bankers are angling to take his company public. He’s even a Hollywood star, with a cameo in the hit Iron Man 2 movie, said to be based on his life story.
