Project 10^100 opens up for voting

It's been a while since Google launched project 10^100 -- created to harvest great ideas from people around the world that could change the world.

Google will invest millions of dollars in the winning ideas -- and that's where you come in. Tonight, Google launched a website that lets you vote on ideas that have been aggregated into several different categories.

Your votes will help an advisory group decide which projects to give funding to over the next couple weeks.
