|INNOVATION: Elon Musk, CEO, Tesla Motors Inc.|
After years of hearing people say that Tesla's Model S -- an electric vehicle with a 250-mile range and faster than a Porsche -- was a pipe dream, serial production began in earnest this year.
Musk, 42, also has set up a factory-owned retail channel and a bespoke fast-charging network and has laid plans for a massive battery manufacturing plant.
Tesla's quarterly profits may come scattered with asterisks, but the numbers are headed in the right direction. The company's stock is a Wall Street darling. All this was accomplished while Musk's other companies launched rockets into space and installed residential solar panels by the tens of thousands.
This would be a landmark career for most CEOs. For Musk, it was just another year.
