40位40岁以下商界精英：往届人物今何在

艾隆•马斯克

• 目前头衔：亿万富翁，创业者，发明家

• 上榜时间（排名）：2010年（第16位）

马斯克或许是这个世界上最忙碌的人。他是电动汽车制造商特斯拉（Tesla）的联合创始人兼CEO，是火箭公司SpaceX的创始人兼CEO，是太阳能供应商SolarCity的董事会主席。而且，他还在考虑新的项目。今年，马斯克提出了一个被大肆炒作的城市交通计划——Hyperloop。他表示，通过该计划，乘客从洛杉矶到旧金山仅需要30分钟，时速达到350英里。此外，他还展示了一款可用手势控制的电脑程序的原型【灵感来自电影《钢铁侠》（Iron Man）】。大家是不是觉得这些创意还太过遥远？理论上确实如此。然而，当初电动汽车公司能够实现盈利也被许多人认为是遥不可及的目标，但马斯克的特斯拉在今年就实现了盈利。不过，现在讨论他的自动驾驶汽车计划依然为时过早。

Elon Musk

• Current title: Billionaire, entrepreneur, inventor

• Year on list (rank): 2010 (No. 16)

Musk may be the world's busiest man. He is co-founder and CEO of electric car maker Tesla, founder and CEO of rocket company SpaceX, and the chairman of solar power provider SolarCity. And still, he's tacking on projects. This year, Musk unveiled a much-hyped proposal for urban transit that he called the Hyperloop, which he said would be able to transport passengers from Los Angeles to San Francisco in just 30 minutes, at 350 miles per hour. He also showed off a prototype for a computer program that you can control by simply moving your hands (a la the "Iron Man" movies) . Far-fetched? Sure. But so was the idea that an electric car company could be profitable, and Musk's Tesla managed that this year. Still too soon to say about his plans to get that car to drive itself, though.
