Google has just announced a new project: Project 10^100 (pronounced "Project 10 to the 100th"), which is a global call for ideas to change the world by helping as many people as possible. Here’s how it works. You submit your idea by October 20th. Google will cull through everything and post 100 ideas. Starting on January 27, 2009, the world starts voting on those to choose 20 semi-finalists. From there, an advisory board will choose 5 finalists. Then, Google will spend at least $10 M implementing those final 5 ideas.
