Google seems to be establishing a presence for discussing "radical technology ideas for solving global problems" at Solve for X. I thought there might be some overlap of ideas here, so this is for anyone that hasn't already seen it elsewhere. It might just be hype, though. (I'm inclined to think it probably is, but that may be my cynical side talking. Take everything it says with a grain of salt.)

There doesn't seem to be much more to say about the site at the moment.

Edit: Video presentations are starting to appear here.
