Meet the Next Jobs, Gates or Zuckerberg

Sixteen hundred teenagers have invaded Los Angeles, but don't worry. It's unlikely they will be creating much mayhem. Instead, this global group is participating in the Intel International Science and Engineering Fair . More than $4 million in prize money is at stake, and Intel has been involved in the competition for nearly two decades.

There are no dioramas or baking soda volcanos at this science fair. Rather, you'll find inventions to clean up oil spills, cut down on carbon emissions, or put drums in your pants. Literally.

Two of three contestants here are from the US, but this is also an opportunity to entice the world's youngest and brightest to come to America.

Winners will be announced Friday, but here are interviews with two of the finalists, Dimitri Xue of China, and Aseem Mishra of the UK.
