Late last year we announced Project 10^100, a call for ideas to help as many people as possible, and a program to bring the best of those ideas to life with a total of $10 million. We hoped to capture the imagination of people around the world and offer a way to bring their best ideas to fruition. We were overwhelmed by the response — you sent us more than 150,000 ideas (approximately 10^5.2) in more than 25 languages and it took more than 3,000 Googlers in offices around the world to review the submissions. (The review process took us much longer than we expected and we appreciate your patience!)

Some ideas we received suggested broad areas of investment, others were very specific technology or implementation proposals, and many of the ideas shared overlapping elements. So rather than posting individual idea submissions, we've decided to do something a little different. We've pooled similar ideas into a set of 16 top idea themes aimed at addressing some important common goals, from making government more transparent to driving innovation in public transport. Every theme has different possible implementations and we intend to consider all reasonable possibilities. But we need your help.

Over the next two weeks we'll be gathering your votes to help inform an advisory board that will then choose up to five winning ideas that will receive funding. After that, we'll present the finalists and ask for proposals from individuals or organizations that can implement these ideas.

It has been a long road for those of us who have worked on this from the beginning. Although it took a lot longer than we first planned, we're pleased with the outcome. In the end, we followed the tried-and-true Google method of "launch and iterate." We enjoyed going through so many interesting proposals and adapted to the massive volume of ideas. We are incredibly proud to be able to put these 16 ideas in front of you to see what you think. Let the voting begin!
