wesolveforx.com . it was rumored some time ago by the New York Times in a article called "Google's lab of Wildest Dreams" that X was referring to a secret lab of Google where they where gathering the brightest minds to solve all kind of issues in the most futuristic ways imaginable. Accoording to the New York Times Sebastian Thrun, one of the world's top robotics and artificial intelligence experts, is a leader at Google Sebastian Thrun, one of the world's top robotics and artificial intelligence experts, is a leader at Google X.
BY looking at the WOIS information of the domain your could see the website was indeed registered by Google. Now Google is releasing more information about "we solve for X" and it turns out that is a great think tank where some great minds are gathering and where everyone else also can participate via the internet to find solutions on some of worlds great challenges in all kind of fields.
Some people already made comparisons to TED.com however in my opinion it go's way future than TED. Within TED you have a broadcasting way of communication where Google X is likely to evolve as a more continuos corporation and social interaction kind of platform. It would be good to keep an eye on the google+ page, the youtube channel and the website of Google X to see where this is heading however it might bring some intersting insights and possibly products in the future.
Or in the words of Google:
"Solve for X is a place to hear and discuss radical technology ideas for solving global problems. Radical in the sense that the solutions could help billions of people. Radical in the sense that the audaciousness of the proposals makes them sound like science fiction. And radical in the sense that there is some real technology breakthrough on the horizon to give us all hope that these ideas could really be brought to life.
This combination of things - a huge problem to solve, a radical solution for solving it, and the breakthrough technology to make it happen - is the essence of a moonshot.
Solve for X is intended to be a forum to encourage and amplify technology-based moonshot thinking and teamwork. This forum started with a small face-to-face event co-hosted by Astro Teller, Megan Smith, and Eric Schmidt - the Solve for X talks are now being posted here on this site. We encourage you to watch the Solve for X talks, join the G+ conversation, and post your own Solve for X talks."
